异构查询需要ANSI_NULLS

我写过一个触发器。异构查询需要ANSI_NULLS

USE [TEST] 
GO 
/****** Object: Trigger [dbo].[TR_POSTGRESQL_UPDATE_YC] Script Date: 05/26/2010 08:54:03 ******/ 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 

ALTER TRIGGER [dbo].[TR_POSTGRESQL_UPDATE_YC] ON [dbo].[BCT_CNTR_EVENTS] 

FOR INSERT 
AS 
BEGIN 


DECLARE @MOVE_TIME varchar(14); 
DECLARE @MOVE_TIME_FORMATED varchar(20); 
DECLARE @RELEASE_NOTE varchar(32); 
DECLARE @CMR_NUMBER varchar(15); 
DECLARE @MOVE_TYPE varchar(2); 

SELECT @MOVE_TIME = inserted.move_time 
     ,@MOVE_TYPE = inserted.move_type 
     ,@RELEASE_NOTE = inserted.release_note 
     ,@CMR_NUMBER = inserted.cmr_number FROM inserted 


IF(@MOVE_TYPE = 'YC') 
    BEGIN 

    SET @MOVE_TIME_FORMATED = SUBSTRING(@MOVE_TIME,1,4) + '-' + SUBSTRING(@MOVE_TIME,5,2) + '-' + SUBSTRING(@MOVE_TIME,7,2) + ' 00:00:00' 

    --UPDATE OpenQuery(POSTGRESQL_SERV,'SELECT visit_cmr,visit_timestamp,visit_pin FROM VISIT') 
    --  SET visit_cmr = @RELEASE_NOTE 
    --  WHERE visit_timestamp = @MOVE_TIME_FORMATED 
    --  AND visit_pin = right(@CMR_NUMBER,5) 
    --  AND visit_cmr IS NULL 

    END 

    SET NOCOUNT ON; 
END

我收到一个错误，当我试图插入一行。

异构查询需要为连接设置ANSI_NULLS和ANSI_WARNINGS选项。这确保了一致的查询语义。启用这些选项，然后重新发出您的查询。

之后，我试图使用SET SET ANSI_WARNINGS is ON，但它不起作用。（链接服务器的PostgreSQL触发）

同样的错误在触发设置为“ON”的时候？ – gbn 2010-05-26 06:12:24

语法好的。我在我的本地服务器上做了一个测试'触发器' - 这是一个很好的工作！..但是在一个真正的服务器上，它给我一个错误（我用php应用程序）来插入行。 **异构查询需要为连接设置ANSI_NULLS和ANSI_WARNINGS选项。这确保了一致的查询语义。启用这些选项，然后重新发布您的查询。** – Dezigo 2010-05-26 06:19:38

尝试使用此

GO 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 

ALTER TRIGGER [dbo].[TR_POSTGRESQL_UPDATE_YC] ON [dbo].[BCT_CNTR_EVENTS] 

AFTER INSERT 
AS 
BEGIN 


DECLARE @MOVE_TIME varchar(14); 
DECLARE @MOVE_TIME_FORMATED varchar(20); 
DECLARE @RELEASE_NOTE varchar(32); 
DECLARE @CMR_NUMBER varchar(15); 
DECLARE @MOVE_TYPE varchar(2); 

SELECT @MOVE_TIME = inserted.move_time 
     ,@MOVE_TYPE = inserted.move_type 
     ,@RELEASE_NOTE = inserted.release_note 
     ,@CMR_NUMBER = inserted.cmr_number FROM inserted 


IF(@MOVE_TYPE = 'YT') 
    BEGIN 

    SET @MOVE_TIME_FORMATED = SUBSTRING(@MOVE_TIME,1,4) + '-' + SUBSTRING(@MOVE_TIME,5,2) + '-' + SUBSTRING(@MOVE_TIME,7,2) + ' 00:00:00' 

    SET ANSI_NULLS ON 
    SET ANSI_WARNINGS ON 

    UPDATE OpenQuery(POSTGRESQL_SERV,'SELECT visit_cmr,visit_timestamp,visit_pin FROM VISIT') 
      SET visit_cmr = @RELEASE_NOTE 
      WHERE visit_timestamp = @MOVE_TIME_FORMATED 
      AND visit_pin = right(@CMR_NUMBER,5) 
      AND visit_cmr IS NULL 

    END 

    SET NOCOUNT ON; 
END
