而不是输入“NXT_US.dbo”。一遍又一遍，我还能怎么做？

SELECT DISTINCT 
                      NXT_US.dbo.icsp.prod, NXT_US.dbo.icsp.descrip##1, NXT_US.dbo.icsp.descrip##2, NXT_US.dbo.icsw.whse, NXT_US.dbo.sastn.descrip AS branch, NXT_US.dbo.icsw.qtyonhand, NXT_US.dbo.icsp.unitstock AS UOM, NXT_US.dbo.apsv.vendno AS VendorNumber, 
                      NXT_US.dbo.apsv.name AS VendorName, NXT_US.dbo.icsp.prodcat, NXT_US.dbo.sasta.descrip, NXT_US.dbo.icsw.prodline, NXT_US.dbo.icsw.statustype, NXT_US.dbo.icsw.lastinvdt, NXT_US.dbo.oeel.invoicedt, NXT_US.dbo.icsw.avgcost, NXT_US.dbo.oeel.vendno, 
                      NXT_US.dbo.icsw.avgcost * NXT_US.dbo.icsw.qtyonhand AS ExtCost, NXT_US.dbo.oeel.prodcost, NXT_US.dbo.oeel.orderno
INTO InventoryView
FROM         NXT_US.dbo.sasta INNER JOIN
                      NXT_US.dbo.icsp ON NXT_US.dbo.sasta.codeval = NXT_US.dbo.icsp.prodcat LEFT OUTER JOIN
                      NXT_US.dbo.icswu ON NXT_US.dbo.icsp.prod = NXT_US.dbo.icswu.prod LEFT OUTER JOIN
                      NXT_US.dbo.icsw LEFT OUTER JOIN

                      NXT_US.dbo.sastn RIGHT OUTER JOIN

第一次在 FROM 子句中使用每个表时为其命名。然后，您可以在 SELECT、WHERE、GROUP BY 子句中使用别名。这是示例（但使用的别名比我放在这里的通用别名更好）：

SELECT DISTINCT 
                      t2.prod, t2.descrip##1, t2.descrip##2, t4.whse, t6.descrip AS branch, t4.qtyonhand, t2.unitstock AS UOM, t8.vendno AS VendorNumber, 
                      t8.name AS VendorName, t2.prodcat, t1.descrip, t4.prodline, t4.statustype, t4.lastinvdt, t5.invoicedt, t4.avgcost, t5.vendno, 
                      t4.avgcost * t4.qtyonhand AS ExtCost, t5.prodcost, t5.orderno
INTO InventoryView
FROM         NXT_US.dbo.sasta AS t1 INNER JOIN
                      NXT_US.dbo.icsp AS t2 ON t1.codeval = t2.prodcat LEFT OUTER JOIN
                      NXT_US.dbo.icswu AS t3 ON t2.prod = t3.prod LEFT OUTER JOIN
                      NXT_US.dbo.icsw AS t4 LEFT OUTER JOIN
                      NXT_US.dbo.oeel AS t5 ON t4.lastinvdt = t5.invoicedt AND t4.whse = t5.whse AND t4.prod = t5.shipprod RIGHT OUTER JOIN
                      NXT_US.dbo.sastn AS t6 RIGHT OUTER JOIN
                      NXT_US.dbo.icsd AS t7 ON t6.cono = t7.cono AND t6.codeval = t7.divno ON t4.whse = t7.whse ON t2.prod = t4.prod LEFT OUTER JOIN
                      NXT_US.dbo.apsv AS t8 ON t4.arpvendno = t8.vendno
WHERE     (t1.cono = '1') AND (t1.codeiden = 'c') AND (t4.statustype = 's') AND (t2.cono = '1') AND (t6.codeiden = 'V') and t4.whse = 'G010'
