Question

I’m confounded. The following MySQL query:

SET @a := 0;   

SELECT * 
  FROM users;

Gives the error:

Invalid query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘SELECT * FROM users’ at line 2`

When I switch the order of the statements, I get the same error, again on line 2 (even though I switched them)

However, either line by themselves runs fine. What could possibly cause this?

Answer 1

I bet you’re trying to perform this query in the mysql_query() (or some similar function from any programming language), but it accepts only single query. So the solution is to split this queries into 2 calls.
