SQL SERVER先判断视图是否存在然后再创建视图的语

如果我们的语句为： IF NOT EXISTS(SELECT 1 FROM sys.views WHERE name='Report_IndividualTicket')BEGINcreate view Report_IndividualTicketasSELECT Ticket.TicketNumber, Ticket.TicketID,GisProcess.StageName,Content.DtReceived, Content.Co

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

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_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
