您可以运行此查询

SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%%' --if you want to find specific column write here 
ORDER BY schema_name, table_name;

在Oracle中，有两个描述列的视图:

DBA_TAB_COLUMNS描述所有表、视图和的列 数据库中的集群。 USER_TAB_COLUMNS描述表、视图和的列 当前用户拥有的集群。属性 老板列。

SELECT A.COLUMN_NAME, A.* FROM all_tab_columns a 
WHERE table_name = 'Your Table Name'
AND A.COLUMN_NAME = 'COLUMN NAME' AND a.owner = 'Schema'

对于MySQL，使用

SELECT column_name 
FROM information_schema.columns 
WHERE 
table_schema = 'Schema' AND table_name = 'Table_Name'

答案在这里:http://php.net/manual/en/function.mysql-list-fields.php 在你的情况下，我会使用以下代码:

$result = mysql_query("SHOW COLUMNS FROM sometable");
if (!$result) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}
$fields = array();
if (mysql_num_rows($result) > 0) {
    while ($row = mysql_fetch_assoc($result)) {
        $fields[] = $row['Field'];
    }
}

对甲骨文

SELECT column_name FROM user_tab_cols WHERE table_name=UPPER('tableName');
