sybase function for MS-SQL Server

Hi, I am working on Unix(Solaris 2.8) with Apache 1.3 and php4. I need to connect MS-SQL Server without ODBC. I know there is an option that using freetds but I haven't tried it yet. Someone told me that sybase functions can work with MS-SQL Server directly. So I called sybase_xxx() instead of mssql_xxx(). I was surprised that most of them really work! But the problem is that sybase_query() seems only work for "select ..." statement. When I tried to pass "insert...","update..." or "delete...", this function returned "false", but the database was actually updated. And the following sybase_query() would always return "false" even it is for "select...". Here is an example: $conn=mssql_connect("MS-SQL Server","login","password"); //successful sybase_select_db("db",$conn); //return true $result=@sybase_query("select ...",$conn); //Great! That's what I want. sybase_free_result($result); //no problem so far $result=@sybase_query("insert ...",$conn); //return false, but I did insert a new record into SQL Server. sybase_free_result($result); //successful $result=@sybase_query("select...",$conn); //return false, can't work with "select..." any more. ... Anybody had same experience before? I will appriecate any information from you. Wen __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
