在SQL SERVER存储过程中帮助IF

can anyone help me with construction of an IF in a stored procedure in sql server.

任何人都可以帮我在sql server中的存储过程中构建IF。

Basically I have a simple stored procedure but I now need to pass in a new input parameter which depending if it is true I pass the value D and if its false I pass the value A. But the change is in the middle of a subquery.. let me explain... here is the stored procedure. basically if I send in True for ReturnOldStatus I execute the subquery ItemStatus='D' and if it is false then i pass in ItemStatus='A'

基本上我有一个简单的存储过程,但我现在需要传入一个新的输入参数,这取决于它是否为真我传递值D,如果它是假,我传递值A.但是更改是在子查询的中间。让我解释一下......这是存储过程。基本上如果我为ReturnOldStatus发送True,我执行子查询ItemStatus ='D',如果它是false,那么我传入ItemStatus ='A'

CREATE PROCEDURE [dbo].[MyTempStoredProc]
(
 @IdOffice                                 Int,
 @ReturnOldStatus                           bit
)
AS
BEGIN
   SET NOCOUNT ON;
   SELECT * FROM Offices

   WHERE
      IdOffice = @IdOffice  

      AND (V.OffType NOT IN (
                        SELECT *  FROM MiscOff 
                        WHERE
ItemStatus= 'D') // This needs to be ItemStatus ='A' if FALSE is passed in on the input param

Any ideas??

Thanks

I would solve it like this:

我会像这样解决它:

    declare @itemStatus varchar(1);
    if (@inputParam = 'FALSE')
    begin
        set @itemStatus = 'A'
    end
    else
        set @itemStatus = 'D'

   SELECT * FROM Offices
   WHERE
          IdOffice = @IdOffice      
          AND (V.OffType NOT IN (
                   SELECT *  FROM MiscOff 
                   WHERE ItemStatus= @itemStatus) 
              )

T-Sql is not my native language, so there may be errors in there...

T-Sql不是我的母语,因此可能存在错误......

Just use the T-SQL if statement:

只需使用T-SQL if语句:

IF @ReturnOldStatus = 0
    BEGIN
        --Some statements
    END
ELSE
    BEGIN
        --Some other statements
    END

I think this will suffice for your problem. If not, look into the DECLARE/SET statements in TSQL.

我认为这足以解决您的问题。如果没有,请查看TSQL中的DECLARE / SET语句。

CREATE PROCEDURE [dbo].[MyTempStoredProc] 
    (@IdOffice Int, 
     @ReturnOldStatus bit ) 
AS BEGIN 
    SET NOCOUNT ON; 

    SELECT * FROM Offices 
    WHERE IdOffice = @IdOffice  
          AND (V.OffType NOT IN (SELECT * FROM MiscOff 
                                 WHERE (ItemStatus= 'D' AND @ReturnOldStatus = 1)
                                         OR
                                       (ItemStatus= 'A' AND @ReturnOldStatus = 0) 
                                )
