SQL Server Stored Procedure Output Params In PHP

I need help running a stored procedure from SQL Server in PHP. PHP is running on a Unix/Linux server. We cannot get OUTPUT variables to return in PHP. The following is the PHP c

Solution 1:

According to this page on PHP bugs, you have to (emphasis mine):

call mssql_next_result() for each result set returned by the SP. This way you can handle multiple results.

When mssql_next_result() returns false you will have access to output parameters and return value.

Solution 2:

The second param of execute needs to be true, rather than conn. This should work:

$conn = mssql_connect('server', 'user', 'pass');
mssql_select_db('db', $conn);

$procedure = mssql_init('usp_StoredProc', $conn);

$tmpVar1 = 'value';
$tmpVar2 = 'value2';

$outVar1 = '';
$outVar2 = '';

mssql_bind($procedure, "@var1", $tmpVar1, SQLVARCHAR, false, false);
mssql_bind($procedure, "@var2", $tmpVar2, SQLVARCHAR, false, false);

mssql_bind($procedure, "@outVar1", $outVar1, SQLVARCHAR, true);
mssql_bind($procedure, "@outVar2", $outVar2, SQLVARCHAR, true);

mssql_execute($procedure,true);

print($outVar1);
print($outVar2);

Solution 3:

Try specifying the specific lengths of the output fields

mssql_bind($procedure, "@outVar1", &$outVar1, SQLVARCHAR, true, false, 36);
mssql_bind($procedure, "@outVar2", &$outVar2, SQLVARCHAR, true, false, 36);

And see if that makes a difference.

Also note the explicit & to pass the output vars by reference, though I don't know if it's still required or not.

Solution 4:

I doubt this is causing your problem, but why are you using DISTINCT?

That's just a codesmell - any time you see that, it means that there is a potential for returning duplicates that is being "handled" with DISTINCT, and why duplicates would be returned probably needs to be looked at.

Solution 5:

Not sure which version of PHP you are running, but i think in some of the older ones you needed to pass variables by reference to get the value to come out again:

So you'd need to put the & charcter before the variable when calling the function:

mssql_bind($procedure, "@outVar1", &$outVar1, SQLVARCHAR, true);
mssql_bind($procedure, "@outVar2", &$outVar2, SQLVARCHAR, true);

Also according to this link some versions had a issue with output paramters
