Question

我有以下SQL语句，因此我可以使用sp_executesql使用if not exists编写视图创建脚本，但由于我上一个where语句中的单引号为1，因此该语句给出了错误。有没有办法解决？

    IF NOT EXISTS (SELECT * FROM SYS.objects WHERE NAME = 'vw_JeopardyAlertDetails' AND    TYPE = 'V')
    EXEC sp_executesql @statement = N'CREATE VIEW [dbo].[vw_JeopardyAlertDetails]
AS 
    SELECT Main.TicketNumber, TS.TicketStateDesc, Main.ApptEnd, ISNULL(C.FirstName, '') AS FirstName, ISNULL(C.LastName, '') AS LastName, ISNULL(Main.CustomerID, '') 
                   AS CustomerID, Main.ApptID, Main.ID, Main.TicketType
    FROM  (SELECT s.TicketState, s.TicketID AS ID, s.ApptEnd, dbo.Ticket.TicketNumber, dbo.Ticket.TimeOpened, dbo.Ticket.CreatedBy, dbo.Ticket.ReportedBy, 
                                  dbo.Ticket.ModifiedBy, dbo.Ticket.ChangedBy, dbo.Ticket.Priority, dbo.Ticket.ServingArea, dbo.Ticket.StructureLink, dbo.Ticket.CustomerID, 
                                  dbo.Ticket.TicketCategory, dbo.Ticket.TicketCode, s.ApptStart, s.TicketType, s.CanReschedule, ISNULL(s.ID, 0) AS ApptID
                   FROM   dbo.Schedule AS s INNER JOIN
                                  dbo.Ticket ON s.TicketID = dbo.Ticket.ID
                   WHERE (s.TicketState IN
                                      (SELECT DISTINCT TicketState
                                       FROM   dbo.AlertJeopardyTicketState
                                       WHERE (IsJeopardyState = '1'))) AND (s.ApptEnd >= CONVERT(DATETIME, CONVERT(VARCHAR(10), GETDATE(), 111) + ' ' + dbo.GetJeopardyStartTime())) 
                                  AND (s.ApptEnd <= GETDATE())) AS Main LEFT OUTER JOIN
                   dbo.Customer AS C ON Main.CustomerID = C.ID LEFT OUTER JOIN
                   dbo.TicketStatus AS TS ON Main.TicketState = TS.ID
    GO' ;
    ELSE PRINT N'vw_JeopardyAlertDetails ALREADY EXISTS'
GO

您需要在Sql @statement中加倍这些引号，例如

ISNULL(C.FirstName, '')

需要

ISNULL(C.FirstName, '''')

在sp_executesql中使用单引号时出错
