MySQL will then run the INSERT statement to replace the deleted row. When a row with the same unique value is found, then the row will be deleted using the DELETE statement.MySQL will check the existing record to see if a row with the same unique value already exists.Note: The existing records in the target table are unaffected. The INSERT INTO SELECT statement requires that the data types in source and target tables matches. The statement essentially does two things: The INSERT INTO SELECT statement copies data from one table and inserts it into another table.

MYSQL INSERT SQL UPDATE

The REPLACE statement is an alternative to the ON DUPLICATE KEY UPDATE clause. Using the REPLACE statement for when a unique value already exists. This query is useful if you still want the row to be updated when the unique value already exists. When a duplicate value is found, then MySQL will perform an update instead of an insert. INSERT INTO users ( user_id, first_name, last_name ) VALUES ( 202, "Tony", "Smith" ) ON DUPLICATE KEY UPDATE first_name = "Tony", last_name = "Smith" įirst, MySQL will execute the regular insert query above.

The MySQL INSERT IGNORE statement is commonly used to change the error that MySQL throws when you use a normal INSERT statement into a warning so that the execution of your query isn’t interrupted.įor example, suppose you have a users table with the following data: Insert a new row if not exists using INSERT IGNORE Without putting a constraint on the column that you want to be distinct, then the queries below won’t work as intended. Keep in mind that before you create an insert if not exists query, the MySQL table in use must already have one or more column(s) with PRIMARY KEY or UNIQUE constraint.

Using the ON DUPLICATE KEY UPDATE clause.

There are three ways you can perform an “insert if not exists” query in MySQL: Still, if you want to perform an insertion only when the data doesn’t already exist, then you need to create a work-around solution with the statements provided by MySQL. This is because when you have table column(s) with PRIMARY KEY or UNIQUE constraint, then MySQL will throw an error each time your query inserts a new row with duplicate values for those columns. Using this statement you can store the output for both DATE and TIME. Using DATETIME you can store both the date and the time.
