范例
Example #1 odbc_next_result()
<?php
$r_Connection = odbc_connect ( $dsn , $username , $password );
$s_SQL = <<<END_SQL
SELECT 'A'
SELECT 'B'
SELECT 'C'
END_SQL;
$r_Results = odbc_exec ( $r_Connection , $s_SQL );
$a_Row1 = odbc_fetch_array ( $r_Results );
$a_Row2 = odbc_fetch_array ( $r_Results );
echo "Dump first result set" ;
var_dump ( $a_Row1 , $a_Row2 );
echo "Get second results set " ;
var_dump ( odbc_next_result ( $r_Results ));
$a_Row1 = odbc_fetch_array ( $r_Results );
$a_Row2 = odbc_fetch_array ( $r_Results );
echo "Dump second result set " ;
var_dump ( $a_Row1 , $a_Row2 );
echo "Get third results set " ;
var_dump ( odbc_next_result ( $r_Results ));
$a_Row1 = odbc_fetch_array ( $r_Results );
$a_Row2 = odbc_fetch_array ( $r_Results );
echo "Dump third result set " ;
var_dump ( $a_Row1 , $a_Row2 );
echo "Try for a fourth result set " ;
var_dump ( odbc_next_result ( $r_Results ));
?> 以上例程会输出：
Dump first result set array(1) {
["A"]=>
string(1) "A"
}
bool(false)
Get second results set bool(true)
Dump second result set array(1) {
["B"]=>
string(1) "B"
}
bool(false)
Get third results set bool(true)
Dump third result set array(1) {
["C"]=>
string(1) "C"
}

Try for a fourth result set bool(false)

Using dbase always returns false or -1. It won't work. Just like odbc_num_rows.

This function works exactly like its equivalent Microsoft SQL Server function: mssql_next_result(). The information above is rather vague and a bit misleading, so refer to the mssql version of this function for details on to use it properly.
P.S. It works with stored procedures.
