判斷插入值是否重復(fù)：
CREATE PROCEDURE IR_rb_User_UpdateUser
(
@UserID int,
@Name nvarchar(50),
@Email nvarchar(100),
@Password nvarchar(20),
@RoleID int,
@iSuccess int output
)
AS
set @iSuccess = -1 --判斷是否成功有錯(cuò)誤應(yīng)為插入重復(fù)鍵
IF EXISTS (SELECT Email FROM rb_Users WHERE Email = @Email and UserID<>@UserID)
BEGIN
set @iSuccess = -2
return
END
BEGIN TRAN
UPDATE rb_Users SET Name = @Name, Email = @Email, Password = @Password WHERE UserID = @UserID
IF @@ERROR <> 0
BEGIN
ROLLBACK TRAN
return
END
set @iSuccess = -3
update rb_UserRoles set RoleID=@RoleID where UserID=@UserID
IF @@ERROR <> 0
BEGIN
ROLLBACK TRAN
return
END
COMMIT TRAN
set @iSuccess = 1

條件查詢(xún)語(yǔ)句：
CREATE PROCEDURE IR_SysAuthorization_GetAllSysAuthorization
(
@Type int,
@UserID varchar(20)
)
AS
declare @strsql varchar(1500) --臨時(shí)sql語(yǔ)句
declare @strwhere varchar(1000) --臨時(shí)sql的條件語(yǔ)句
set @strsql = ''

set @strsql = @strsql + '(CASE WHEN State = 1 THEN ' + '''有效''' + ' ELSE ' + '''無(wú)效''' + ' END) AS StateTmp '
set @strsql = @strsql + 'FROM SysAuthorization t '

--按用戶(hù)名排序
