我想知道我是否能得到一些帮助,在SQL中,我有两个表,它们之间的关系基于人员ID,我想写sp,检查人员是否已经退出:执行insert语句,否则执行update语句。
我正在检查的表是否为值IsExit-name:GSACPeopleBargeRequest
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[spUpdateIDBadgeInfo]
@PersonID Int,
@RequestedBy Int,
@RequestedOn SmallDatetime,
@BadgeStatusType Int,
@ShippedLocationID Int,
@Notes Varchar(500)= NULL,
@Active bit
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
SET NOCOUNT ON;
DECLARE @retVal INT
SET @retVal = 0
DECLARE @CheckVal Bit
SET @CheckVal = 0
IF @PersonID > 0
BEGIN
'#####################################How do this right.###########################
@CheckVal = select * from GSACPeopleBadgeRequest where PersonID = @PersonID
-- Check if there is any personID in GSACPeopleRequest, if not make a new insert
else
Update dbo.GSACPeopleBadgeRequest
SET
RequestedBy = @RequestedBy,
RequestedOn = @RequestedOn,
BadgeStatusType = @BadgeStatusType,
ShippedLocationID = @ShippedLocationID ,
Notes = ISNULL(@Notes,@Notes),
Active = @Active
WHERE PersonID = @PersonID
-- Set the return value
SET @retVal = CAST(@@ROWCOUNT As int)
Select @retVal
END
END
GO
我认为您想在找不到@perseid时进行插入,否则如果存在,则更新,但在您的问题中,它以相反的方式解释。试试这个。
IF NOT EXISTS (SELECT 1
FROM GSACPeopleBadgeRequest
WHERE PersonID = @PersonID)
INSERT INTO GSACPeopleBadgeRequest
(RequestedBy,RequestedOn,BadgeStatusType,ShippedLocationID,Notes,Active)
SELECT @RequestedBy,
@RequestedOn,
@BadgeStatusType,
@ShippedLocationID,
Isnull(@Notes, ''),
@Active
ELSE
UPDATE dbo.GSACPeopleBadgeRequest
SET RequestedBy = @RequestedBy,
RequestedOn = @RequestedOn,
BadgeStatusType = @BadgeStatusType,
ShippedLocationID = @ShippedLocationID,
Notes = Isnull(@Notes, ''),
Active = @Active
WHERE PersonID = @PersonID
-- Set the return value
SET @retVal = Cast(@@ROWCOUNT AS INT)
