例1 cubrid_next_result() example

<?php
$conn
= cubrid_connect("127.0.0.1", 33000, "demodb", "dba");

$sql_stmt = "SELECT * FROM code; SELECT * FROM history WHERE host_year=2004 AND event_code=20281";
$res = cubrid_execute($conn, $sql_stmt, CUBRID_EXEC_QUERY_ALL);

get_result_info($res);
cubrid_next_result($res);
get_result_info($res);

function
get_result_info($req)
{
printf("\n------------ get_result_info --------------------\n");

$row_num = cubrid_num_rows($req);
$col_num = cubrid_num_cols($req);

$column_name_list = cubrid_column_names($req);
$column_type_list = cubrid_column_types($req);

$column_last_name = cubrid_field_name($req, $col_num - 1);
$column_last_table = cubrid_field_table($req, $col_num - 1);

$column_last_type = cubrid_field_type($req, $col_num - 1);
$column_last_len = cubrid_field_len($req, $col_num - 1);

$column_1_flags = cubrid_field_flags($req, 1);

printf("%-30s %d\n", "Row count:", $row_num);
printf("%-30s %d\n", "Column count:", $col_num);
printf("\n");

printf("%-30s %-30s %-15s\n", "Column Names", "Column Types", "Column Len");
printf("------------------------------------------------------------------------------\n");

$size = count($column_name_list);
for(
$i = 0; $i < $size; $i++) {
$column_len = cubrid_field_len($req, $i);
printf("%-30s %-30s %-15s\n", $column_name_list[$i], $column_type_list[$i], $column_len);
}
printf("\n\n");

printf("%-30s %s\n", "Last Column Name:", $column_last_name);
printf("%-30s %s\n", "Last Column Table:", $column_last_table);
printf("%-30s %s\n", "Last Column Type:", $column_last_type);
printf("%-30s %d\n", "Last Column Len:", $column_last_len);
printf("%-30s %s\n", "Second Column Flags:", $column_1_flags);

printf("\n\n");
}
?>

上の例の出力は以下となります。
