您可以使用information_schema简单地获取一个表的所有列。列只需添加group_concat以获得逗号分隔的列列表。
select group_concat( column_name ) as ColumnNames from information_schema.columns where table_schema = 'ur_db_name' and table_name = 'ur_tbl_name'
列出MySQL表中的所有字段:
select *
from information_schema.columns
where table_schema = 'your_DB_name'
and table_name = 'Your_tablename'
<?php
$table = 'orders';
$query = "SHOW COLUMNS FROM $table";
if($output = mysql_query($query)):
$columns = array();
while($result = mysql_fetch_assoc($output)):
$columns[] = $result['Field'];
endwhile;
endif;
echo '<pre>';
print_r($columns);
echo '</pre>';
?>
