我同意只选择*是不够的，如果你不需要，正如在其他地方提到的，是一个BLOB，你不希望有这个开销。

我会用所需的数据创建一个视图，然后您可以轻松地选择*——如果数据库软件支持它们的话。否则，将大量数据放到另一个表中。

我喜欢@Mahomedalid的回答，除了@Bill Karwin评论中提到的事实。@Jan Koritak提出的可能的问题是真的，我遇到过，但我找到了一个技巧，只是想在这里与面临这个问题的人分享。

我们可以在Prepared语句的子查询中用where子句替换replace函数，如下所示:

使用我的表和列名

SET @SQL = CONCAT('SELECT ', (SELECT GROUP_CONCAT(COLUMN_NAME) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'users' AND COLUMN_NAME NOT IN ('id')), ' FROM users');
PREPARE stmt1 FROM @SQL;
EXECUTE stmt1;

因此，这将只排除字段id，而不包括company_id

(不要在大桌子上尝试，结果可能是……令人惊讶的!)

临时表

DROP TABLE IF EXISTS temp_tb;
CREATE TEMPORARY TABLE ENGINE=MEMORY temp_tb SELECT * FROM orig_tb;
ALTER TABLE temp_tb DROP col_a, DROP col_f,DROP col_z;    #// MySQL
SELECT * FROM temp_tb;

DROP语法可能因数据库而异

您可以使用DESCRIBE my_table并使用其结果动态地生成SELECT语句。

虽然我同意Thomas的答案(+1;))，但我想补充一点，即我假设您不想要的列几乎不包含任何数据。如果它包含大量的文本、xml或二进制blob，那么请花时间单独选择每一列。否则你的表现就会受到影响。干杯!

也许我有一个解决Jan Koritak指出的矛盾的方法

SELECT CONCAT('SELECT ',
( SELECT GROUP_CONCAT(t.col)
FROM
(
    SELECT CASE
    WHEN COLUMN_NAME = 'eid' THEN NULL
    ELSE COLUMN_NAME
    END AS col 
    FROM INFORMATION_SCHEMA.COLUMNS 
    WHERE TABLE_NAME = 'employee' AND TABLE_SCHEMA = 'test'
) t
WHERE t.col IS NOT NULL) ,
' FROM employee' );

表:

SELECT table_name,column_name 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_NAME = 'employee' AND TABLE_SCHEMA = 'test'

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

table_name  column_name
employee    eid
employee    name_eid
employee    sal

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

查询结果:

'SELECT name_eid,sal FROM employee'
