Question

第一次提出问题，长时间访问者和自己编写的必要编码，因为Excel并没有削减它！那就是说...请善待，我对此很新。

我有两张桌子，比较＆＃39;和＆＃39; himsshospital＆＃39;在架构＆＃39; physician_compare＆＃39;。两个表都有一列“CCN1＆＃39;”。我想将两个表合并在一起，使用CCN1是匹配的标识符。两个表中都没有主键。我想将重复值保留在＆＃39;比较＆＃39;表格，只需在＆＃39; himsshospital＆＃39;中添加列表即可。表基于CCN1。在excel中，这相当于在比较＆＃39;中基于CCN1进行vlookup。表，而不是参考“他的医院”＃39;桌子和拖下来。最终产品将是＆＃39;比较＆＃39;与相应的医院相关的桌子＆＃39;添加到其中的列根据CCN1进行匹配。

从我的论坛搜索，我认为我需要进行内部联接，但不断收到错误，例如错误代码：1146表不存在＆＃39;或者＆＃39;错误代码：1052列是明确的＆＃39;。

提前谢谢！

这是我之前尝试的查询，我也包含了表/列设置。我正在使用MySQL Workbench。

 select tbl_names.CCN1
 from tbl_names.compare
 inner join tbl_names.himsshospital
 on tbl_names.CCN1=tbl_names.CCN1;`

Answer 1

可能是合并是加入betten tbl_names.compare和tbl_names.himsshospital的alis然后你应该为每一侧使用不同的表格（两侧的表格列tbl_names.CCN1 = tbl_names.CCN1不同）

   use physician_compare;

   select tbl_names.CCN1
   from tbl_names.compare and 
   inner join tbl_names.himsshospital
   on tbl_names.CCN1=himsshospital.CCN1;

基于单列标识符的表合并
