其他答案充分回答了这个问题，但我想分享一些额外的信息。其他人描述“describe table”语法以获取表信息。如果你想获得相同格式的信息，但不使用DESCRIBE，你可以这样做:

SELECT column_name as COLUMN_NAME, nullable || '       ' as BE_NULL,
  SUBSTR(data_type || '(' || data_length || ')', 0, 10) as TYPE
 FROM all_tab_columns WHERE table_name = 'TABLENAME';

可能不太重要，但我之前写过，它似乎是合适的。

我是这样做的

SELECT 
    TOP 0
    *
FROM
    Posts

它甚至可以在http://data.stackexchange.com的服务表我不知道!

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'];
    }
}

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;

select column_name,* from information_schema.columns
 where table_name = 'YourTableName'
order by ordinal_position

在SQL Server中…

SELECT [name] AS [Column Name]
FROM syscolumns
WHERE id = (SELECT id FROM sysobjects WHERE type = 'V' AND [Name] = 'Your table name')

Type = 'V'表示视图 Type = 'U'表示表
