Question

I have the below stored procedure to check the user name availability

DELIMITER $$;  DROP PROCEDURE IF EXISTS tv_check_email$$  CREATE PROCEDURE tv_check_email (IN username varchar(50)) BEGIN   select USER_ID from tv_user_master where EMAIL=username; END$$  DELIMITER ;$$ 

When I run this from my MySQL front end tool, it is works just fine:

call tv_check_email('[e-mail]') 

But when trying to execute from the PHP page, I get an error like

'PROCEDURE mydatabase.tv_check_email can't return a result set in the given context' 

I am sure that my PHP version is 5.2.6.

Cody is not 100% right. You can bind your resulting return columns and return select data from within a stored procedure.

$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'world');  $stmt = $mysqli->prepare('call tv_check_email(?)'); $stmt->bind_param('s', '[e-mail]'); $stmt->execute();  $stmt->bind_result($userid);  while ($stmt->fetch()) {   printf('User ID: %d\n', $userid); }  $stmt->close(); $mysqli->close();
