我不能为我的生活弄清楚这段代码有什么问题:
IF NOT EXISTS(SELECT * FROM sys.columns WHERE name = 'Report_Date'
AND object_id = OBJECT_ID('TempTable3'))
ALTER TABLE TempTable3 ADD Report_Date datetime
--Set "ReportDate" field to the date the data was extracted less one.
UPDATE TempTable3
SET Report_Date = '20100815'
我一直收到这个错误:
"Msg 207, Level 16, State 1, Line 51
Invalid column name 'Report_Date'."
答案 0 :(得分:1)
在alter table
之后放一个GOALTER TABLE TempTable3 ADD Report_Date datetime
GO
