SQL SERVER先判断视图是否存在然后再创建视图的语句

时间:2014-08-17 08:00 浏览:

如果我们的语句为:

IF NOT EXISTS(SELECT 1 FROM sys.views WHERE name='Report_IndividualTicket')
BEGIN
create view Report_IndividualTicket
as
SELECT Ticket.TicketNumber, Ticket.TicketID,
GisProcess.StageName,
Content.DtReceived, Content.ContentText
FROM
(GisProcess INNER JOIN Ticket
ON GisProcess.TicketID=Ticket.TicketID)
INNER JOIN Content
ON Ticket.ContentID=Content.ContentID
END 

ZJJKW.CN

会提示以下错误: www.zJjkw.cn

Msg 156, Level 15, State 1, Line 4
Incorrect syntax near the keyword 'view'.

出现这个错误的原因是:create view 这一句必须是批处理中的第一句。

所以可以将该语句修改为:

IF EXISTS(SELECT 1 FROM sys.views WHERE name='Report_IndividualTicket')
DROP VIEW Report_IndividualTicket
GO
create view Report_IndividualTicket
as
SELECT Ticket.TicketNumber, Ticket.TicketID,
GisProcess.StageName,
Content.DtReceived, Content.ContentText
FROM
(GisProcess INNER JOIN Ticket
ON GisProcess.TicketID=Ticket.TicketID)
INNER JOIN Content
ON Ticket.ContentID=Content.ContentID
GO wwW.zjjkw.cn
