如何連接3臺MSSQL服務器

Question

在一個數據庫中，我有如下三個表：

我想將它們串聯在一些單個表，什麼建議嗎？

Answer 1

感謝。

SELECT mtlreq.proposalid, mtlreq.prp_mtlreq_taskgrp,mtlreq.prp_mtlreq_taskcode,mtlreq.prp_mtlreq_itemcode,mtlreq.prp_mtlreq_rateper,mtlreq.prp_mtlreq_qty,mtlreq.prp_mtlreq_Inter_MaterCost,mtlreq.prp_mtlreq_UOM,mtlreq.item_short_desc, resreq.proposalid,resreq.prp_resreq_taskcode ,resreq.prp_resreq_resource,resreq.prp_resreq_usage,resreq.prp_resreq_uom,resreq.prp_resreq_rate,resreq.prp_resreq_overhd_pers 
FROM (
    SELECT proposalid,prp_mtlreq_taskgrp,prp_mtlreq_taskcode,prp_mtlreq_itemcode,prp_mtlreq_rateper,prp_mtlreq_qty,prp_mtlreq_Inter_MaterCost,prp_mtlreq_UOM,item_short_desc, 
      ROW_NUMBER() OVER (ORDER BY proposalid) AS rn 
    FROM prjdet_prp_taskwork_mtlreq ) AS mtlreq 
FULL OUTER JOIN (
    SELECT proposalid,prp_resreq_taskcode ,prp_resreq_resource,prp_resreq_usage,prp_resreq_uom,prp_resreq_rate,prp_resreq_overhd_pers, 
      ROW_NUMBER() OVER (ORDER BY proposalid) AS rn 
    FROM prjdet_prp_taskwork_resreq) AS resreq 
ON mtlreq.rn = resreq.rn 
FULL OUTER JOIN (
SELECT proposalid,mtprp_delv_lineno,mtprp_delv_itemcode,mtprp_delv_cost,mtprp_delv_linelevelmrg,mtprp_delv_proposedamt, 
      ROW_NUMBER() OVER (ORDER BY proposalid) AS rn 
    FROM prjproposal_delidtl) AS delidtl 
    on mtlreq.rn = delidtl.rn and resreq.rn=delidtl.rn 

Answer 2

如果我理解正確的答案，你想是這樣的：

CREATE TABLE COMBINED (/*Insert the set of fields here*/); 
GO 

INSERT INTO COMBINED 
    SELECT Table1.ProposalId 
     , /*all other Table1 fields*/ 
     , Table2.ProposalId 
     /*all other Table2 fields*/ 
     , Table3.ProposalId 
     , /*all other Table2 fields*/ 
    FROM Table1 
    FULL JOIN Table2 
     ON Table1.ProposalId = Table2.ProposalId 
    FULL JOIN Table3 
     ON Table1.ProposalId = Table3.ProposalId; 

這將匹配具有相同的提案編號行（但保留所有的值proposalid_1，proposalid_2 ...和對於那些不匹配會帶來全行NULL對錶的其餘部分的每一個領域。對你有所幫助的問題已經解決
