如果愿意，可以使用SQL生成SQL，并对生成的SQL进行评估。这是一种通用的解决方案，因为它从信息模式中提取列名。下面是一个Unix命令行的示例。

替换

MYSQL的MYSQL命令 带有表名的TABLE 包含排除字段名的EXCLUDEDFIELD

echo $(echo 'select concat("select ", group_concat(column_name) , " from TABLE") from information_schema.columns where table_name="TABLE" and column_name != "EXCLUDEDFIELD" group by "t"' | MYSQL | tail -n 1) | MYSQL

实际上，您只需要以这种方式提取列名一次，就可以构造排除该列的列列表，然后只需使用已构造的查询。

比如:

column_list=$(echo 'select group_concat(column_name) from information_schema.columns where table_name="TABLE" and column_name != "EXCLUDEDFIELD" group by "t"' | MYSQL | tail -n 1)

现在可以在构造的查询中重用$column_list字符串。

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。

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;

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'

我很晚才想出一个答案，坦率地说，这是我一直在做的事情，它比最好的答案要好100倍，我只希望有人能看到它。发现它很有用

    //create an array, we will call it here. 
    $here = array();
    //create an SQL query in order to get all of the column names
    $SQL = "SHOW COLUMNS FROM Table";
        //put all of the column names in the array
        foreach($conn->query($SQL) as $row) {
            $here[] = $row[0];
        }
    //now search through the array containing the column names for the name of the column, in this case i used the common ID field as an example
    $key = array_search('ID', $here);
    //now delete the entry
    unset($here[$key]);

我同意列出所有列的“简单”解决方案，但这可能会造成负担，而且打字错误可能会浪费大量时间。我使用“getTableColumns”函数检索适合粘贴到查询中的列的名称。然后我要做的就是删除我不想要的。

CREATE FUNCTION `getTableColumns`(tablename varchar(100)) 
          RETURNS varchar(5000) CHARSET latin1
BEGIN
  DECLARE done INT DEFAULT 0;
  DECLARE res  VARCHAR(5000) DEFAULT "";

  DECLARE col  VARCHAR(200);
  DECLARE cur1 CURSOR FOR 
    select COLUMN_NAME from information_schema.columns 
    where TABLE_NAME=@table AND TABLE_SCHEMA="yourdatabase" ORDER BY ORDINAL_POSITION;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
  OPEN cur1;
  REPEAT
       FETCH cur1 INTO col;
       IF NOT done THEN 
          set res = CONCAT(res,IF(LENGTH(res)>0,",",""),col);
       END IF;
    UNTIL done END REPEAT;
  CLOSE cur1;
  RETURN res;

您的结果返回一个以逗号分隔的字符串，例如…

col1, col2 col3 col4, ... col53
