Question

我有4个表，detail_table，adders_table，form_table和summary_table 前3个表有一个共同的列piece_ID，但是第4个表summary_table没有Piece_ID列，而是有ID列，它只出现在详细信息表中而不是地址和表格表中现在有什么方法可以将所有这4张桌子加在一起吗？

（我已成功加入表格，地址和详细信息表仅保留为摘要）下面是3个表的查询，我得到了成功的结果。

    Select archive_address.PieceID, archive_adf_detail.Job_ID, prod_code, 
seq_number,process_date, seq_queue, addline1, addline2,addline3,addline4,addline5, archive_freeform.free_form1, archive_Free_Form2
from archive_Address join archive_adf_detail
on archive_address.PieceID = archive_adf_detail.F_key
join archive_freeform
on archive_address.PieceID = archive_freeform.PieceID
Where (archive_Address.addline1 like '%Cons%' 
or archive_Address.addline2 like '%Cons%' )
and archive_Address.pieceID like '%FB2K%'
order by addline1

我正在使用以下查询添加第4个表格

Select archive_address.PieceID, archive_adf_detail.Job_ID, prod_code, job_summary.Status_Date,
seq_number,process_date, seq_queue, addline1, addline2,addline3,addline4,addline5, archive_freeform.free_form1, archive_freeform.Free_Form2
from archive_Address join archive_adf_detail
on archive_address.PieceID = archive_adf_detail.F_key
join archive_freeform
on archive_address.PieceID = archive_freeform.PieceID
join job_summary 
on archive_adf_detail.job_ID = job_summary.job_ID
Where (archive_Address.addline1 like '%Cons%' 
or archive_Address.addline2 like '%Cons%' )
and archive_Address.pieceID like '%FB2K%'
order by addline1

执行上述操作后，我收到以下错误：

Msg 207, Level 16, State 1, Line 8
Invalid column name 'jobID'.
Msg 209, Level 16, State 1, Line 1
Ambiguous column name 'prod_code'.
Msg 209, Level 16, State 1, Line 2
Ambiguous column name 'seq_number'.
Msg 209, Level 16, State 1, Line 2
Ambiguous column name 'process_date'.
Msg 207, Level 16, State 1, Line 2
Invalid column name 'archive_Free_Form2'.

如果我使用的语法不正确或者无法像这样加入第4个表格，请纠正我谢谢！

根据查询表达的关系连接表。你的联盟很好。

该错误与以下事实有关：列的名称在表的集合中不是唯一的（不明确的：具有多个含义）。您需要指定具有列名的表。

Select 
    archive_address.PieceID, 
    archive_Address.addline1,
    archive_Address.addline2,
    archive_Address.addline3,
    archive_Address.addline4,
    archive_Address.addline5,
    archive_adf_detail.prod_code,
    archive_adf_detail.seq_number,
    archive_adf_detail.process_date,
    archive_adf_detail.seq_queue,
    archive_freeform.Job_ID,
    archive_freeform.free_form1,
    archive_freeform.Free_Form2,
    job_summary.Status_Date
From archive_Address 
Join archive_adf_detail on archive_address.PieceID = archive_adf_detail.F_key
Join archive_freeform on archive_address.PieceID = archive_freeform.PieceID
Join job_summary on archive_freeform.job_ID = job_summary.job_ID
Where (archive_Address.addline1 like '%Cons%' or archive_Address.addline2 like '%Cons%' )
and archive_Address.pieceID like '%FB2K%'
Order by archive_Address.addline1

我并不完全确定您已传达了架构，因为您问题中的错误消息与第二个查询不对应。您需要了解哪些数据在哪里以及您想要哪些部分。
