What is the usage of “IGNORE” in MySQL?

In MySQL, IGNORE is a modifier typically used to ignore specific errors when inserting data. When using the IGNORE modifier, if the insertion operation results in certain errors (like duplicate key errors), MySQL will disregard those errors and continue with the insertion process.

IGNORE is commonly used in conjunction with the INSERT statement to ignore duplicate key errors when inserting data. For example:

INSERT IGNORE INTO table_name (column1, column2) VALUES (value1, value2);

In the example above, if there are records in the table_name table with the same values in column1 and column2, the duplicate key error will be ignored and the insertion operation will continue.

It is important to note that the IGNORE modifier can only be used for specific errors and will not display any error message. Therefore, when using IGNORE, make sure to understand the possible errors that may occur and confirm whether they can be ignored.
