Here the final code

// will not specify scrollable if it’s DML commands
function _execute($sql)
{
$sql = $this->_prep_query($sql);
if(stripos($sql,’UPDATE’) !== FALSE || stripos($sql,’INSERT’) !== FALSE) {
return sqlsrv_query($this->conn_id, $sql, null, array());
}
return sqlsrv_query($this->conn_id, $sql, null, array(
‘Scrollable’ => SQLSRV_CURSOR_STATIC,
‘SendStreamParamsAtExec’ => true
));
}
function affected_rows()
{
return @sqlsrv_rows_affected($this->result_id);
}

It works perfectly with my SQL 2008 instance except the only error message

ERROR: [2] sqlsrv_rows_affected(): supplied resource is not a valid sqlsrv_stmt resource (line 297)

be written in the CI’s log when I call affected_rows() after an UPDATE execution.

I figured it out by change affected_rows()’s code, according to MSDN(http://msdn.microsoft.com/en-us/library/cc296178(SQL.90).aspx), to

function affected_rows()
{
return @sqlsrv_rows_affected($this->result_id);
}

which seems to fix the problem.

I got an error when using the version 1.1

Fatal error: Call to undefined function sqlsrv_connect() in ……/system/database/drivers/sqlsrv/sqlsrv_driver.php on line 85

What can I do to fix this?

Hopefully this will be included in the main CI build soon.

Great site design, btw.

Spent Hours upon Hours trying to connect to MIcrosoft SQL 2005 Server.

I’ve actually found a few minutes to update the driver for php_sqlsrv.dll version 1.1, and CodeIgniter 1.7.2 – You can get a newer version of it from the following URL:

http://www.phrenzy.org/code/sqlsrv-1.1.tar.gz

It contains many of the fixes mentioned in the comments here, plus a few from the CodeIgniter forums. I hope this helps some of you.

I followed the instructions on the Microsoft site to install the new PHP driver. I did have to create an empty db_set_charset function in sqlsrv_driver.php to finally get it to work.

Thanks again for your work!

I also got a blank screen and “PHP Fatal error: Call to undefined method CI_DB_sqlsrv_driver::_db_set_charset(). Adding function db_set_charset to sqlsrv_driver.php solved the issue:

function db_set_charset($charset, $collation) { return TRUE; }

(Using IIS7, SQL Server 2008 and Codeigniter 1.7.2)

First port of call would be to check your IIS7 error log, and your connection settings in config/database.php.
