将单引号与 sp_executesql 一起使用时出错

Question

我有以下 SQL 语句，以便我可以使用 if not exists with 编写视图创建脚本，sp_executesql但是由于最后一个 where 语句中的单引号，该语句给了我错误。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 中将这些引号加倍，例如

ISNULL(C.FirstName, '')

需要是

ISNULL(C.FirstName, '''')
