I need to exec my sql statement with "set nocount on" and "set nocount off" within the for-loop by the function of mssql_query. But it seems only to be successful at the first time and the others were failed with the error message "MSSQL Query Failed". My platform is WinNT4.0sp4+Apache1.3.14+Php4.03pl1+MSSQL7.0sp2. The sql-statement is
<pre>
 $db = mssql_connect("test","","");
 for ($i=0;$i<=3;$i++){
     $SQLstr = "set nocount on
                select news from table_news 
                set nocount off";
     $result = mssql_query($SQLstr,$db);
     print $result;
 }
 mssql_close($db);

========================
The result is:
 1
 Warning: MS SQL: Query failed in c:\test.php3 on line 16
 Warning: MS SQL: Query failed in c:\test.php3 on line 16
</pre>
I use the mssql profiler to trace the execution. I found that the sql statement was only executed at the first time and another times were not found. Is this is a bug of mssql_query ?

Thanks anyway,

Vicent,Lin.

Divide your query into three.
You dont need to set options at each query. Options should be ste once in each session.

There is some supplement about this problem. May be  described sql-statement is not a good example, so it will
confuse the point. There are several SQL-command instead of
the original select query (select news from table),and these
SQL command may be closed by transaction because the query are related. And the for loop is used for several
indep. operations, so set option can't be put outside the loop.
