Bug Type: PDO related
Operating System: Windows XP
PHP Version: 5.2.4
Assigned To: fmk
New Comment:
I was able to reproduce this error using the 2008-01-05 snapshot of
PDO_ODBC.
Reproduce code:
---------------
<?php
$db = new PDO('odbc:Driver={SQL Server}; Server=localhost; Uid=test;
Pwd=test; Database=test;');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->exec('CREATE TABLE #foo (id INT NOT NULL)');
$db->exec('INSERT INTO #foo VALUES(1)');
$stmt = $db->prepare('SELECT id FROM #foo WHERE id IN (SELECT id FROM
#foo WHERE id = ?)');
$stmt->bindValue(1, 1, PDO::PARAM_INT);
$stmt->execute();
var_dump($stmt->fetch(PDO::FETCH_ASSOC));
?>
Expected result:
----------------
array(1) { ["id"]=> string(1) "1" }
Actual result:
--------------
PHP Fatal error: Uncaught exception 'PDOException' with message
'SQLSTATE[42000]: Syntax error or access violation: 306 [Microsoft][ODBC
SQL Server Driver][SQL Server]The text, ntext, and image data types
cannot be compared or sorted, except when using IS NULL or LIKE
operator. (SQLExecute[306] at ..\pecl_5_2\pdo_odbc\odbc_stmt.c:133)'
A trace using the Profiler tool shows that the bound integer value is
incorrectly interpreted as text:
CREATE TABLE #foo (id INT NOT NULL)
go
INSERT INTO #foo VALUES(1)
go
declare @P1 int
set @P1=NULL
exec sp_prepare @P1 output, N'@P1 text', N'SELECT id FROM #foo WHERE id
IN (SELECT id FROM #foo WHERE id = @P1)', 1
select @P1
go
Incorrect: N'@P1 text'
It should be: N'@P1 int'

Very nice that you didn't bother trying with the RCs..

the problem still occurs on:
PHP 5.2.4 (cli) (built: Aug 30 2007 07:06:31)

This bug affects my app, too. I'm using PHP 5.2.3 on Windows XP Pro
SP2, under both IIS 5.1 and Apache 2.2, with SQL Server 2005 Express.
I don't know if it'll help or not, but here's some more reproduce code.
Just fix the PDO DSN string to something valid.
<?php
$db = new PDO("odbc:dsn=$odbcDsn;uid=$user;pwd=$pass");
$createTable =
'CREATE TABLE ##test (
intCol int,
textCol varchar(20)
)';
$createTable2 =
'CREATE TABLE ##test2 (
intCol2 int,
textCol2 varchar(20)
)';
$db->exec($createTable);
$db->exec($createTable2);
$ins = $db->prepare('INSERT INTO ##test (intCol, textCol) VALUES (:i,
:t)');
$ins->execute(array('i'=>1, 't'=>'A String'));
$ins2 = $db->prepare('INSERT INTO ##test2 (intCol2, textCol2) VALUES
(:i, :t)');
$ins2->execute(array('i'=>1, 't'=>'Another String'));
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE textCol2 = :t)');
$sel->execute(array('t'=>'Another String')) or
var_dump($sel->errorInfo());
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE intCol2 = :i)');
$sel->execute(array('i'=>1)) or var_dump($sel->errorInfo());
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE textCol2 = :t)');
$sel->bindValue('t', 'Another String');
$sel->execute() or var_dump($sel->errorInfo());
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE intCol2 = :i)');
$sel->bindValue('i', 1);
$sel->execute() or var_dump($sel->errorInfo());
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE textCol2 = :t)');
$sel->bindValue('t', 'Another String', PDO::PARAM_STR);
$sel->execute() or var_dump($sel->errorInfo());
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE intCol2 = :i)');
$sel->bindValue('i', 1, PDO::PARAM_INT);
$sel->execute() or var_dump($sel->errorInfo());
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE textCol2 = :t)');
$t = 'Another String';
$sel->bindParam('t', $t, PDO::PARAM_STR);
$sel->execute() or var_dump($sel->errorInfo());
$sel = $db->prepare('SELECT * FROM ##test WHERE intCol = (SELECT
intCol2 FROM ##test2 WHERE intCol2 = :i)');
$i = 1;
$sel->bindParam('i', $i, PDO::PARAM_INT);
$sel->execute() or var_dump($sel->errorInfo());
?>

Hey Wez, I never saw the feedback til I stumbled on it today, and
clearly have been able to work around this, but it does keep stopping
me.
It happens exactly the same if I omit the PDO::PARAM_INT as the final
parameter.
I am still using the branched version you gave me... I'd be happy to
test with the latest if you think it might be fixed there.
