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" } bool(false) Try for a fourth result set bool(false)
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.
Using dbase always returns false or -1. It won't work. Just like odbc_num_rows.
