Hi,
I am using this SP, am getting both the result when using mysql workbench.
CREATE PROCEDURE SP(IN _start INT,IN _end INT,INOUT _count INT)
BEGIN
SET _count = (SELECT COUNT(*) FROM tbl);
SET @qry = CONCAT('select * from tbl limit ', _start, ',', _end);
PREPARE stmt FROM @qry;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END
But when using with PDO am returning this error
$c=0;
$stmt = $this->_dbc->getConnection()->prepare("CALL SP(0,10,:count)");
$stmt->bindParam(":count",$c,PDO::PARAM_INT|PDO::PARAM_INPUT_OUTPUT,0);
$stmt->execute();
return $c;
PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1414 OUT or INOUT argument 3 for routine db22.SP is not a variable or NEW pseudo-variable in BEFORE trigger
But on changing
$this->_dbc->getConnection()->prepare("CALL SP(0,10,[B]:count[/B])");
to
$this->_dbc->getConnection()->prepare("CALL SP(0,10,@count)");
am not returning any error, but always getting the count as 0.
1.Whats the difference between :count and @count ?
2.How to get exact count via pdo ?
