问题描述
谁能在这个查询中找到我的错误?我正在使用 SQL Server 2000，我想将 CostEntry 表中的所有条目更新为 ActiveCostDetails 表中的相应值.where 子句确实适用于 select 语句.
Can anyone find my error in this query? I'm using SQL Server 2000 and I want to update all entries in the CostEntry table to the corresponding value in the ActiveCostDetails table. The where clause DOES work with a select statement.
UPDATE CostEntry CE
INNER JOIN ActiveCostDetails As AD ON CostEntry.lUniqueID = ActiveCostDetails.UniqueID
SET CostEntry.sJobNumber = ActiveCostDetails.JobNumber
WHERE CostEntry.SEmployeeCode = '002'
AND SubString(CostCentre, 1, 1) = sDepartmentCode
AND substring(CostCentre, 3, 1) = sCategoryCode
AND substring(CostCentre, 5, 2) = sOperationCode
推荐答案
SET 需要位于查询的 FROMJOINWHERE 部分之前.p>
The SET needs to come before the FROMJOINWHERE portion of the query.
UPDATE CE
SET sJobNumber = AD.JobNumber
FROM CostEntry CE
INNER JOIN ActiveCostDetails As AD
ON CE.lUniqueID = AD.UniqueID
WHERE CE.SEmployeeCode = '002'
AND SubString(CostCentre, 1, 1) = sDepartmentCode
AND substring(CostCentre, 3, 1) = sCategoryCode
AND substring(CostCentre, 5, 2) = sOperationCode
