Question

I Have 2 Table “users” and “querys”. Normally i use

INSERT INTO querys (row1,row2,row3) values(.....)
UPDATE users SET credit=credit-1 ......

I want to use one query.

Answer 1

You can write multiple statements using the semi-colon delimiter. Additionally, you can use a transaction to ensure that both statements execute in your batch.

START TRANSACTION;
INSERT INTO querys (row1,row2,row3) values('A', 'B', 'C');
UPDATE users SET credit=credit-1;
COMMIT;
