(PHP 4 >= 4.0.5, PHP 5, PECL odbtp:1.1.1-1.1.4)
mssql_next_result — Move the internal result pointer to the next result
Описание
When sending more than one SQL statement to the server or executing a stored procedure with multiple results, it will cause the server to return multiple result sets. This function will test for additional results available form the server. If an additional result set exists it will free the existing result set and prepare to fetch the rows from the new result set.
Список параметров

-
The result resource that is being evaluated. This result comes from a call to mssql_query().
Возвращаемые значения
Returns TRUE if an additional result set was available or FALSE otherwise.

This function does not exist as a Sybase (Sybase-CT) alias, so if you have PHP+FreeTDS||Sybase as a MSSQL client on Unix platform, it will not work.It seems that mssql_next_result does not work with result sets returned by stored procedures.you cant return multiple values from store proc but you can return multiple resultset, so you can use mssql_next_result()
eg..
$stmt = mssql_init("AuthLoginUser", $objDBH);
mssql_bind($stmt,"@LoginUser",$LoginUser,SQLVARCHAR);
mssql_bind($stmt,"@Password",$strNewPassword,SQLVARCHAR);
mssql_bind($stmt,"@SessionId",$SessionId,SQLVARCHAR);
//mssql_bind($stmt,"@ReturnVal",$ReturnVal,SQLVARCHAR,True);
$rs=mssql_execute($stmt);
do {
while ($row = mssql_fetch_row($rs)) {
echo "$row[0] -- $row[1]<BR>";
}
} while (mssql_next_result($rs));
mssql_free_result($rs);
When retrieving multiple resultsets from a stored procedure, don't call mssql_free_statement on the statement resource, as any resultsets not yet retrieved will be lost, and mssql_next_result will report no more result sets were available.As of today, this function is defined in FreeTDS (at least in the CVS version) and works perfectly with stored procedures.
Useful to avoid outer joins.
