首页 / 数据库 / SQLServer / 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_IndividualTicket"）BEGINcreate view Report_IndividualTicketasSELECT Ticket.TicketNumber, Ticket.TicketID,GisProcess.StageName,Content.DtReceived, Content.ContentTextFROM（GisProcess INNER JOIN TicketON GisProcess.TicketID=Ticket.TicketID）INNER JOIN ContentON Ticket.ContentID=Content.ContentIDEND

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_IndividualTicketGOcreate view Report_IndividualTicketasSELECT Ticket.TicketNumber, Ticket.TicketID,GisProcess.StageName,Content.DtReceived, Content.ContentTextFROM（GisProcess INNER JOIN TicketON GisProcess.TicketID=Ticket.TicketID）INNER JOIN ContentON Ticket.ContentID=Content.ContentIDGO
