Description:
------------
In moving from PHP 5.1.6 to 5.2.9 I've lost the ability to bind to a
LIMIT or OFFSET parameter against MySQL 5.0; that is, if I have
... LIMIT ?
or
... OFFSET ?
it fails with
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 ''3'' at line 1
(where "3" is the actual value of the parameter bound to the ?).
Reproduce code:
---------------
<?php
$dsn = "mysql:host=localhost;dbname=test";
$dbh = new PDO($dsn, '', '', array());
run_PDO($dbh, "CREATE TABLE t (n int)", array());
run_PDO($dbh, "select n FROM t LIMIT ?", array(3));
run_PDO($dbh, "select n FROM t LIMIT 3 OFFSET ?", array(3));
run_PDO($dbh, "DROP TABLE t", array());
function run_PDO($dbh, $sql, $params) {
$stmt = $dbh->prepare($sql);
if (!$stmt) {
$i = $dbh->errorInfo();
print "Preparing \"$sql\" failed: $i[2]\n";
} else if (!$stmt->execute($params)) {
$i = $stmt->errorInfo();
print "Executing \"$sql\" failed: $i[2]\n";
} else {
print "\"$sql\" succeeded\n";
}
}
?>
Expected result:
----------------
"CREATE TABLE t (n int)" succeeded
"select n FROM t LIMIT ?" succeeded
"select n FROM t LIMIT 3 OFFSET ?" succeeded
"DROP TABLE t" succeeded
(This is what happens with PHP 5.1.6 MySql 5.0.45)
Actual result:
--------------
"CREATE TABLE t (n int)" succeeded
Executing "select n FROM t LIMIT ?" failed: 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 ''3'' at line 1
Executing "select n FROM t LIMIT 3 OFFSET ?" failed: 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 ''3'' at line 1
"DROP TABLE t" succeeded
(With PHP 5.2.9 MySQL 5.0.77)
