基于@Mahomedalid的答案，我做了一些改进，以支持“选择mysql中除某些列外的所有列”

SET @database    = 'database_name';
SET @tablename   = 'table_name';
SET @cols2delete = 'col1,col2,col3';

SET @sql = CONCAT(
'SELECT ', 
(
    SELECT GROUP_CONCAT( IF(FIND_IN_SET(COLUMN_NAME, @cols2delete), NULL, COLUMN_NAME ) )
    FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @tablename AND TABLE_SCHEMA = @database
), 
' FROM ',
@tablename);

SELECT @sql;

如果确实有很多cols，则使用此sql语句更改group_concat_max_len

SET @@group_concat_max_len = 2048;

据我所知，没有。你可以这样做:

SELECT col1, col2, col3, col4 FROM tbl

并手动选择所需的列。然而，如果你想要很多列，那么你可能只需要做一个:

SELECT * FROM tbl 

忽略你不想要的。

针对你的特殊情况，我建议:

SELECT * FROM tbl

除非你只想要几列。如果你只想要四列，那么:

SELECT col3, col6, col45, col 52 FROM tbl

这很好，但如果您想要50个列，那么任何使查询变得(太?)难以阅读的代码。

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'

我也想要这个，所以我创建了一个函数。

public function getColsExcept($table,$remove){
    $res =mysql_query("SHOW COLUMNS FROM $table");

    while($arr = mysql_fetch_assoc($res)){
        $cols[] = $arr['Field'];
    }
    if(is_array($remove)){
        $newCols = array_diff($cols,$remove);
        return "`".implode("`,`",$newCols)."`";
    }else{
        $length = count($cols);
        for($i=0;$i<$length;$i++){
            if($cols[$i] == $remove)
                unset($cols[$i]);
        }
        return "`".implode("`,`",$cols)."`";
    }
}

所以它的工作原理是，你输入表格，然后是你不想要的列或在数组中:array("id"，"name"，"whatevercolumn")

所以在select中你可以这样使用它:

mysql_query("SELECT ".$db->getColsExcept('table',array('id','bigtextcolumn'))." FROM table");

or

mysql_query("SELECT ".$db->getColsExcept('table','bigtextcolumn')." FROM table");

我的主要问题是在连接表时获得了许多列。虽然这不是您问题的答案(如何从一个表中选择除某些列之外的所有列)，但我认为值得一提的是，您可以指定表。从特定表中获取所有列，而不是仅指定。

下面是一个很有用的例子:

select users.*, phone.meta_value as phone, zipcode.meta_value as zipcode

from users

left join user_meta as phone
on ( (users.user_id = phone.user_id) AND (phone.meta_key = 'phone') )

left join user_meta as zipcode
on ( (users.user_id = zipcode.user_id) AND (zipcode.meta_key = 'zipcode') )

结果是用户表中的所有列，以及从元表中连接的两个附加列。
