Suppress Errors When Duplicate Data Is Inserted in MySQL

There are times in which we need to suppress some errors that are not impacting what we currently are working on.

In MySQL, we may want to suppress an error that is caused by duplicate data insertion with INSERT IGNORE.

Code snippet:

CREATE TABLE `EMPLOYEE` (   `FIRSTNAME` VARCHAR(25) NOT NULL,   `LASTNAME` VARCHAR(25) NOT NULL,   PRIMARY KEY (FIRSTNAME, LASTNAME));INSERT IGNORE INTO EMPLOYEE (FIRSTNAME, LASTNAME) VALUES( 'Ray', 'Neil');

Expected result:

-- First time insertionINSERT IGNORE INTO EMPLOYEE (FIRSTNAME, LASTNAME) VALUES( 'Ray', 'Neil');/* Affected rows: 1  Found rows: 0  Warnings: 0  Duration for 1 query: 0.016 sec. */-- Subsequent insertionINSERT IGNORE INTO EMPLOYEE (FIRSTNAME, LASTNAME) VALUES( 'Ray', 'Neil');/* Affected rows: 0  Found rows: 0  Warnings: 0  Duration for 1 query: 0.000 sec. */
