In MySQL, the DELETE query is used to remove one or more rows from a table based on specified conditions. It allows you to selectively delete records that meet certain criteria. Let's discuss the details of the DELETE query in MySQL:

Syntax:

                
    DELETE FROM table_name WHERE condition;
                
            

Explanation of the syntax elements:

* DELETE FROM: This keyword combination indicates that you want to delete rows from a table.

* table_name: This is the name of the table from which you want to delete rows.

* WHERE: This keyword is used to specify the conditions that determine which rows should be deleted. If you omit the WHERE clause, all rows in the table will be deleted.

* condition: This is the condition that determines which rows should be deleted. It can be a combination of comparisons, logical operators, and functions.

Example:

Let's assume we have a table called "customers" with columns "customer_id", "first_name", "last_name", and "email". Here's an example of a DELETE query:

Syntax:

                
    DELETE FROM customers WHERE customer_id = 1;
                
            

This query deletes the row from the "customers" table where the "customer_id" is equal to 1. Only the row(s) that match the specified condition will be deleted.

You can delete multiple rows at once by specifying more complex conditions in the WHERE clause. Here's an example:

Syntax:

                
    DELETE FROM customers WHERE last_name = 'vikash' AND email LIKE '%@gmail.%';
                
            

This query deletes all rows from the "customers" table where the "last_name" is 'Smith' and the "email" column ends with '@example.com'.

Remember to adjust the table name and condition based on your specific scenario. Be cautious when using DELETE queries as they can permanently remove data from the table. It's a good practice to take a backup before executing DELETE queries, especially when dealing with important data.
