我有不同的表具有相同的结构，我想通过他们的列之一加入他们。
问题是他们不会在该列中共享信息。
表1 - 类型A： 名称|值 表2 - 类型B： 名称|值结果表：
a single column）
nameFromA nameFromB ...到目前为止，我尝试过：
code> SELECT TABLE1.NAME，TABLE2.NAME FROM TABLE1，TABLE2 WHERE TABLE1.NAME ='SearchQuery' OR TABLE2.NAME ='SearchQuery'LIMIT 2;我知道我的查询是错误的，因为我调用更多的列，我不知道如何加入一列中的一切。
$ p> SELECT TABLE1.NAME FROM TABLE1 WHERE TABLE1.NAME ='SearchQuery' UNION SELECT TABLE2 .NAME FROM TABLE2 WHERE TABLE2.NAME ='SearchQuery';您可能想使用 UNION ALL if
要限制结果集，您可以执行以下操作：
SELECT * FROM（这里是上面的查询）LIMIT 2;
I have different tables with the same structure, and I would like to join them by one of their columns.
The problem is that they don't share information in that column.
Table 1 - Type A: Name | Value Table 2 - Type B: Name | ValueResulting table:
(In a single column)
nameFromA nameFromB ...So far, I have tried:
SELECT TABLE1.NAME, TABLE2.NAME FROM TABLE1, TABLE2 WHERE TABLE1.NAME = 'SearchQuery' OR TABLE2.NAME = 'SearchQuery' LIMIT 2;I know that my query is wrong because I'm calling more columns that what I want, but I am not sure how to join everything in a single column. How can I accomplish this?
解决方案Have you tried?
SELECT TABLE1.NAME FROM TABLE1 WHERE TABLE1.NAME = 'SearchQuery' UNION SELECT TABLE2.NAME FROM TABLE2 WHERE TABLE2.NAME = 'SearchQuery';You may want to use UNION ALL if you don't want to exclude repeated values.
To limit your result set you can do something like this:
SELECT * FROM ( HERE GOES ABOVE QUERY ) LIMIT 2;
