DROP and DELETE statements are used in different situations while performing mySQL queries so it is confusing when to use what statement.
you would use the DROP statement when you want to remove an entire database object, such as a table, and all its data. On the other hand, you would use the DELETE statement to remove specific rows or records from a table while keeping the table itself intact.
In summary, use the DELETE statement when you want to remove specific rows from a table while preserving the table structure. On the other hand, use the DROP statement when you want to permanently delete an entire database object and its associated data. Always exercise caution when using the DROP statement, as it can lead to irreversible data loss if used incorrectly.
Delete Statement – This statement is a Data Manipulation Language which is used to remove certain or all records of a table and if by mistake we have deleted that record or records we can retrieve them using commit command followed by rollback command as when we execute the delete command log file is created , all the records get saved in the transaction log which is a MySql feature that records all the modifications in the database in binary format.
Syntax:- DELETE from //table name :- This deletes all the records of your table .
DELETE from //table name
[Where condition]:- This deletes records according to a condition that you specify.
DROP Statement- This statement is a Data Definition Language which is used to remove entire database, index, record or a table and that also permanently which again is the reason why the memory pace gets freed up.
Syntax;-
Drop table //table name;
Drop database //database name;
DELETE is a Data Manipulation Language (DML) command. It is used to remove tuples/records from a relation/table. On the other hand, DROP is a Data Definition Language (DDL) command and is used to remove named elements of schema like relations/table, constraints or entire schema.
Use the DELETE statement when you want to remove specific rows from a table while keeping the table structure intact. Use the DROP statement when you want to permanently remove an entire table or a database from the MySQL server.
The decision to use a DELETE statement or a DROP statement depends on the specific situation and the desired outcome.
DELETE Statement:
(1) The DELETE statement is used to remove specific rows or records from a table while keeping the table structure intact.
(2) Use DELETE when you want to selectively remove specific records based on certain conditions or criteria.
(3) When using DELETE, be careful to provide the appropriate WHERE clause to ensure you delete the intended rows, as omitting the WHERE clause can result in accidentally deleting all rows from the table.
DROP Statement:
(1) DROP statement is used to remove an entire object from the database, such as a table, view, or index.
(2) Use DROP when you want to completely eliminate an entire object and its associated data from the database.
A Data Manipulation Language (DML) command is DELETE.The Data Definition Language (DDL) command is called “DROP.” The difference between the DELETE and DROP commands is that whereas the query may be used to delete one or more records from an existing table based on the criterion supplied, DELETE is used to remove tuples from a table.Additionally, the DROP command is used to delete the database’s whole schema, table, domain, or constraints.
Syntax of delete command-DELETE FROM Table_Name WHERE [Conditions];
Syntax of drop command-DROP TABLE Table_Name;
When working with MySQL queries, it’s important to understand the differences between the DELETE and DROP statements and when to use each one. Here’s a breakdown to help you decide:
DELETE statement:
The DELETE statement is used to remove specific rows from a table that match a given condition. It allows you to selectively delete data while keeping the table structure intact. Here are some key points to consider when using the DELETE statement:
Use DELETE when you want to remove specific rows from a table.
You can use the WHERE clause to specify the condition for row deletion.
Deleting rows with the DELETE statement does not remove the table or its structure.
The data can be recovered if you have a backup or if you have not committed the changes (depending on your transaction settings).
Example:- DELETE FROM table_name WHERE condition;
DROP statement:
The DROP statement is used to remove an entire table, including its structure and all the data stored within it. It is a more drastic action and should be used with caution. Here are some points to consider when using the DROP statement:
Use DROP when you want to completely remove a table and all its data.
Dropping a table removes the table structure, indexes, and associated data.
The action is irreversible, and the data cannot be recovered unless you have a backup.
You may need appropriate privileges to execute the DROP statement.
In summary, use the DELETE statement to remove specific rows from a table, while keeping the table structure intact. Use the DROP statement when you want to delete an entire table, including its structure and all the data. Remember to exercise caution when using the DROP statement, as it permanently removes data. Always back up your data before performing any critical operations.
Example:- DROP TABLE table_name;
Indeed, the DROP and DELETE statements in MySQL serve different purposes and are used in different situations. Here’s a clarification on when to use each statement:
DROP TABLE table_name;(Drops the specified table from the database)DELETE FROM table_name WHERE condition;(Deletes rows from the table that match the specified condition)In summary, use the DROP statement when you want to remove an entire database or table entirely, eliminating all its contents. On the other hand, use the DELETE statement when you want to remove specific rows or records from a table while keeping the table structure intact.
It’s crucial to exercise caution when using these statements, especially the DROP statement, as they permanently affect the data in your database. Always double-check your queries and consider taking backups before executing any potentially destructive statements.
Use the DELETE statement when you want to selectively remove specific rows or subsets of data while keeping the table intact. On the other hand, use the DROP statement when you want to entirely remove database objects, such as tables, views, indexes, or even an entire database. Always exercise caution when using the DROP statement, as it permanently deletes data and cannot be undone without backups.
Use the DELETE statement when you want to selectively remove specific rows or subsets of data while keeping the table intact.

When working with MySQL queries, it’s important to understand the differences between the DELETE and DROP statements and when to use each one. Here’s a breakdown of the two statements and their typical use cases:
Example:
sqlCopy code
DELETE FROM table_name WHERE condition;
Example:
sqlCopy code
DROP TABLE table_name;
In summary, you should use the DELETE statement when you want to selectively remove specific rows from a table while preserving the table structure. On the other hand, you should use the DROP statement when you want to completely remove an entire table, including its structure and all associated data.
It’s crucial to exercise caution when using the DROP statement since it permanently removes the table and its data. It’s recommended to take backups or verify your intentions before executing a DROP statement to avoid unintended data loss.
The DELETE statement is used to delete specific rows from a table, while the DROP statement is used to delete an entire table.
Use the DELETE statement when you want to remove specific rows and the DROP statement when you want to completely remove a table and all its data.
The DELETE statement is used to remove specific rows or data from a table while retaining the table structure. It is typically used when you want to selectively remove records from a table based on certain conditions. The DELETE statement is commonly used in scenarios where you want to delete specific rows but keep the table and its structure intact.
The DROP statement is used to delete an entire table or database from the MySQL server. It removes both the table structure and the data contained within it. The DROP statement is typically used when you want to completely remove a table or database, including all associated data and indexes.
To decide whether to use the DELETE or DROP statement, consider Intention,Data Preservation, Impact, Backup and Recovery
DELETE statement will delete a single row or column of a database. While on the other hand DROP statement is used to delete the whole table structure from your database.
When working with MySQL queries, the decision to use either the DELETE statement or the DROP statement depends on the specific task or goal you want to achieve. Let’s discuss the purpose and usage of each statement to help you make an informed decision:
DELETE Statement: The DELETE statement is used to remove specific records from a table in a database. It is typically used when you want to selectively delete specific rows while keeping the table structure intact. Here are some key points to consider when deciding to use the DELETE statement:
DROP Statement: The DROP statement is used to remove database objects entirely, such as tables, views, indexes, or stored procedures. It is typically used when you want to remove an entire object from the database. Here are some considerations for using the DROP statement:
In summary, use the DELETE statement when you want to selectively remove specific rows from a table while keeping the table structure intact. Use the DROP statement when you want to permanently remove an entire database object from the database, such as a table or a view. Remember to exercise caution when using the DROP statement due to its irreversible nature.
DELETE statement:
The DELETE statement is used to remove specific rows from a table.
It is typically used when you want to selectively remove specific records based on certain conditions or criteria.
The data structure and the table itself remain intact after executing a DELETE statement.
Example usage: DELETE FROM table_name WHERE condition;
Use the DELETE statement when:
You want to remove specific rows from a table while keeping the table’s structure and other data intact.
DROP TABLE table_name;When working with MySQL queries, the decision to use a

When working with MySQL queries, it’s important to understand the differences between the DELETE statement and the DROP statement, as they serve different purposes.
1. DELETE Statement:
The DELETE statement is used to remove specific rows from a table that match certain conditions. It is typically used when you want to selectively remove data from a table while keeping the table structure intact. Here are a few considerations for using the DELETE statement:
– Use DELETE when you want to remove specific rows from a table based on specific criteria.
– DELETE does not remove the table itself or its structure; it only removes data.
– It is a good choice when you want to retain the table structure, indexes, and associated permissions.
– Be cautious when using DELETE without specifying conditions (e.g., without a WHERE clause), as it will remove all rows from the table.
Example DELETE statement:
DELETE FROM table_name WHERE condition;
2. DROP Statement:
The DROP statement is used to remove an entire table, including its structure, indexes, and associated permissions. It essentially deletes the table from the database schema. Here are some considerations for using the DROP statement:
– Use DROP when you want to completely remove a table from the database.
– DROP deletes both the table’s data and its structure, so use it with caution.
– This statement is irreversible, and once a table is dropped, all the data and associated objects are permanently deleted.
– Ensure you have appropriate backups or a data recovery plan before using DROP.
Example DROP statement:
DROP TABLE table_name;
In summary, use the DELETE statement to remove specific rows from a table while retaining the table structure, and use the DROP statement to completely remove a table, including its structure, indexes, and permissions.
drop is used to delete particular whereas drop is used to entirely
In MySQL use DELETE and DROP by seeing the following difference:
1)We use the DELETE statement when we want to remove specific rows from a table while keeping the table structure unchanged, And
2)We use the DROP statement when we want to completely remove an entire table . Complete structure , all data and attributes will get deleted.
Use the DELETE statement to remove specific rows from a table while keeping the table structure intact.
Use the DROP statement to completely remove a table or other database objects along with all associated data and metadata
DELETE Statement: The DELETE statement is used to remove specific rows from a table while keeping the table structure intact. It is typically used when you want to selectively remove data based on certain conditions.
This does not free up space but rather marks the rows as removed so that the space can be taken up by rows which will be added in the future.
Syntax-
DELETE FROM table_name WHERE condition;
DROP Statement: The DROP statement is used to remove database objects entirely from the database, including tables, views, indexes, or entire databases. It is used when you want to completely eliminate an object and all associated data. This does free up space as it removes the object completely along with its configuration.
Syntax –
DROP TABLE table_name
When you want to delete certain rows from a table without maintaining the table’s structure, use the DELETE statement. When you wish to permanently delete a whole table or database from the MySQL server, use the DROP statement.
The DROP statement serves to delete an entire table, including its structure and data, from the database. It is typically used when you don’t need a table anymore or when you want to recreate it with a different structure.
The DELETE instruction is used to delete specific rows or records from a table while preserving the table structure. It is useful when you want to delete data according to special conditions.
In summary, use the DROP statement when you want to remove a whole table from the database, including its structure and data. Use the DELETE instruction to delete specific rows of a table while maintaining the table structure.

It is used when you want to completely eliminate an object and all associated data. This does free up space as it removes the object completely along with its configuration.
Syntax –
DROP TABLE table_name
•To remove specific rows use ‘DELETE’
•To remove complete table with its structure and data use ‘DROP’
In MySQL, it is your choice between the DELETE statement or a DROP statement it all depends on what you want to achieve the context of your query.
Now,explore each Statement;
1. DELETE Statement
The DELETE Statement is used to remove the specific rows from a tables and allows you to delete specific records from a table which are not required.
Examples;
A. Deleting the specific records,
In this case you need to tell a specific condition on which row should be deleted.
B. Deleting all records;
This statement deletes all rows from the specified table.
It is helpful and useful when you want to remove some records while preserving the structure of the table.
2.DROP Statement;
For the completey remove the database like the tables, views , or entire databases in this situation this DROP Statement is used.
Example;
A. dropping a table;
This statement removes the entire table and all its data.
When you want to remove complete database object and you don’t need any of the data or the object itself anymore then this DROP Statement is appropriate.
In short,
Use the DELETE statement when you want to remove some specific rows or all rows from the table while preserving the table structure.
Use the DROP Statement when you want to permanently remove an entire databases object, including its data.
Use the `DELETE` statement when you want to remove specific rows from a table while keeping the table structure intact.
Use the `DROP` statement when you want to permanently delete an entire table or database, including its data and structure. Be cautious as this operation cannot be undone.
When you use the DELETE statement, you have to specify which records you want to delete by using a WHERE clause. For example, if you have a table called “customers” and you want to delete all records where the “age” column is equal to 30, you would use the following SQL statement:
DELETE FROM customers
WHERE age = 30
This would delete all records from the “customers” table where the “age” column is equal to 30.
When you use the DROP statement, you are removing an entire table from the database. For example, if you have a table called “customers” and you want to remove it from the database, you would use the following SQL statement:
DROP TABLE customers;
This would remove the “customers” table and all of its data from the database.
It’s important to note that when you use the DROP statement, all of the data in the table is permanently deleted. This means that if you accidentally execute the DROP statement, you may lose all of your data. So, it’s important to use this statement with caution and make sure you have a backup of your data before executing the statement.
Use DELETE when you want to remove specific rows that meet certain criteria, such as deleting all rows with a specific value in a particular column.
DELETE is typically used to remove data from a table while preserving the table structure, indexes, and associated constraints.
After executing a DELETE statement, the table will still exist, and any other data in the table will remain unaffected.
DROP statement: The DROP statement is used to remove database objects entirely. It is used to delete an entire table, database, or other database objects. Here are some considerations for using the DROP statement:
Use DROP when you want to completely remove a table, along with all its data, indexes, and associated constraints.
DROP permanently deletes the table or database object, and there is no way to retrieve the data once it has been dropped.
DELETE statement:
The DELETE statement is used to remove specific rows from a table that match a given condition. It allows you to selectively delete data while keeping the table structure intact.
Use DELETE when you want to remove specific rows from a table.
DROP :
DROP statement is used whenever you want to delete complete table structure permanently including data.
TRUNCATE statement is also almost similar to DROP statement but truncate is used to delete the all tuples (rows) at once but structure remains in database.
DELETE is the data manipulation language, used to delete data from relation of data while DROP is the data definition language is to remove data like the whole table. DELETE is a part while DROP is whole.
DELETE and DROP belong to the SQL command statement
DELETE statement comes under Data Manipulation Language (DML commands) and it is used to remove or delete a particular row or a column from a table
DROP is a Data defination Language command (DDL command) it is used to remove the described element and also to Eliminate the entire table.
DELETE is used to remove existing records from the database.
DELETE command is a DML statement so that it can be rolled back. And delete particular rows and columns from a table.
DROP is used to delete the whole table, including its structure.
DROP is a DDL command that lost the data permanently, and it cannot be rolled back. Including its structure and data use DROP TABLE statement.
DELETE – It is used when you have to delete a particular record, for example a row or an element in a row.
DROP – It is used when you have to delete a complete column/field, table, database.
Use DELETE when you want to remove specific tuples (rows) from the table, such as deleting all tuples(rows) with a specific value in a particular column. If once DELETE statement is used then the only selected row is deleted from the table.
DROP:
The DROP statement is used to remove the complete table from the database permanently. If once DROP statement is used then the table which is consisting of tuples, attributes all were deleted including table structure too.
TRUNCATE statement is also almost similar to drop statement but slight difference is if we use truncate statement it won’t erase the structure of the table it only removes the data which is existed in the table, but drop statement removes table structure also along with data.
Use delete when you want to remove specific row that meet certain criteria,such as deleting all rows with a specific value in a particular column.
Drop statement — the drop statement is used to remove database objects entirely. It is used to delete entire table ,database or other database objects.
Use drop Statement when you want to completely remove the table with all of its data .
Use DROP command when you want do drop or permanently delete the entire table or database.
Use DELETE command when you want to delete or remove only specific field such as row,column,attribute,etc.
Delete Statement – This statement is a Data Manipulation Language which is used to remove certain or all records of a table and if by mistake we have deleted that record or records we can retrieve them using commit command followed by rollback command
Syntax:- DELETE from //table name :- This deletes all the records of your table .
DELETE from //table name
[Where condition]:- This deletes records according to a condition that you specify.
like [column name ]== <value> so it will delete all the record which is equal to that value.
DROP Statement- This statement is a Data Definition Language which is used to remove entire database, index, record or a table and that also permanently which again is the reason why the memory pace gets freed up.
DROP is a DDL command that lost the data permanently, and it cannot be rolled back. Including its structure and data use DROP TABLE statement.
Syntax;-
Drop table //table name;
Drop database //database name;
DELETEstatement.DROPstatement.The decision to use a DELETE statement or a DROP statement in MySQL queries depends on the specific task requirements. Use DELETE when you want to remove specific rows while preserving the table’s structure and other data. This is useful for deleting subsets of data based on conditions. On the other hand, use DROP when you want to completely remove an entire table, including its structure, data, and associated objects. Exercise caution with DROP, as it permanently deletes the table and its contents. Consider backups and ensure the intention is to remove all associated data and objects.
