SQL SERVER先判断视图是否存在然后再创建视图的语句

如果我们的语句为:

IF NOT EXISTS(SELECT 1 FROM sys.views WHERE name='Report_InpidualTicket')
BEGIN
create view Report_InpidualTicket
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

会提示以下错误:

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_InpidualTicket')
DROP VIEW Report_InpidualTicket
GO
create view Report_InpidualTicket
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
