mssql_query() can't fetch result from server if I use
sql server variables in query. 
For example this script:
<?php
mssql_connect([server],[user],[password])
$sql_result=mssql_query("declare @kala int;select @kala=5;delete from [table] where field1=@kala");

$sql_result2=mssql_query("select * from kasutajad");
?>

If I turned error severity to 0 I saw following 
error:MS SQL error: 
Attempt to initiate a new SQL Server operation with results pending. (severity 7) in c:\htdocs\sqltest.php on line 4

...but the first query has no result to fetch...
