I want to add a row to a database table, but if a row exists with the same unique key I want to update the row.
For example,
insert into table (id, name, age) values(1, "A", 19)
Let’s say the unique key is id
, and in my database there is a row with id = 1
. In that case I want to update that row with these values. Normally this gives an error. If I use insert IGNORE
it will ignore the error, but it still won’t update.
Answer
Use INSERT ... ON DUPLICATE KEY UPDATE
QUERY:
INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE
name="A", age=19
