MySQL：将数据从61列表移动到58列表

我是一个漂亮的绿色新手，仍然是SQL，并且任务非常繁琐。我需要将tableA中61列中的58列移到tableB中。 tableA有61列，只有15行，tableB现在有58列和零行。我已经阅读了关于如何实现这一点的多个源文件（将数据从一个表格移动到相关表格），但没有一个具体谈论我正在处理的这个特定情况。MySQL：将数据从61列表移动到58列表

使事情变得更加复杂，第二个表没有与第一个表的顺序相同的列，所以这也带来了问题。这个SO帖子看起来很有希望，但它正在使用一个相当小的数据集：SQL: Move column data to other table in same relation。这一个也是类似的MYSQL - Move data from one table to a related one?。问题是他们都从一张小桌子移到一张更大的桌子上，而不是面对面。

这里是我的企图使这一过渡发生（和不成功的包括错误指示）初始查询：

INSERT INTO tableB SELECT * FROM tableA; 
ERROR 1136 (21S01): Column count doesn't match value count at row 1

58 rows in set (0.01 sec)

我会包括的模式，如果有人想看看他们。

我想知道是否有一种方法可以做到这一点，而不必在INSERT INTO语句中明确标注每一列。任何帮助将不胜感激！

nah。只需放上一个好的播放列表并剪切并粘贴名称即可。 – Drew

Bill Karwin您看到的结果来自“describe tableA”和“describe tableB”命令。我向你保证，模式分别是61列和58列。我将编辑问题以包含这些命令的完整结果。 – TomJ

啊，以前不清楚你是在查询'describe'而不是'select'。对于在您写回复时删除我的问题，我表示抱歉。 –

没有，有没有办法做到这一点没有标注每列名柱。在SQL没有语法SELECT *_except_for_a_few_columns

可以产生出INFORMATION_SCHEMA列的清单，让您在繁琐的打字减少：

SELECT GROUP_CONCAT(column_name ORDER BY ordinal_position) AS _cols 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE table_schema = 'mydatabase' AND table_name = 'tableA' 
    AND column_name NOT IN ('do', 'not', 'want')

更复杂的是，第二个表不没有与第一个列相同的列...

如果两个表中的列至少有相同的名称，那么可以在INSERT语句中使用列列表，而不管自然顺序位置如何on表中定义的那些列。换句话说，以下工作：

INSERT INTO tableB (col1, col4, col2, col6, col9) 
    SELECT col1, col4, col2, col6, col9 FROM tableA;

如果列数，顺序，和名称有所不同，我建议你仔细检查你插入正确的表！ :-)

尼斯彻底的周到答案 – Drew

正是我在找的东西！在意识到列计数产生的混淆之后，我在原始问题中发布了模式。在原始表中只有15行，我真的很希望有一个更有效的方法来完成这个任务。谢谢你的伟大答案！我接受了它。 – TomJ

是那错误是非常简单的，并说，你不能使用*和需要明确指定像

INSERT INTO tableB 
SELECT col1, col2, col3, ..., col58 FROM tableA;

这就是我所害怕的，正如你所说的，语法错误非常清楚。虽然真的希望有某种秘密的SQL黑魔法！ – TomJ

@TomJ，黑魔法已经被*黑魔法师拼写*见其他答案。 – Rahul
