示例
示例 #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");
}
?>以上示例会输出：
------------ get_result_info -------------------- Row count: 6 Column count: 2 Column Names Column Types Column Len ------------------------------------------------------------------------------ s_name char 1 f_name varchar 6 Last Column Name: f_name Last Column Table: code Last Column Type: varchar Last Column Len: 6 Second Column Flags: ------------ get_result_info -------------------- Row count: 4 Column count: 5 Column Names Column Types Column Len ------------------------------------------------------------------------------ event_code integer 11 athlete varchar 40 host_year integer 11 score varchar 10 unit varchar 5 Last Column Name: unit Last Column Table: history Last Column Type: varchar Last Column Len: 5 Second Column Flags: not_null primary_key unique_key
