Question

I have 3 tables such as

IndentHeader:

 IndentID        StatusID 
--------         ------   
    1             5      
    2             5

IndentDetail:

IndentID         ItemID           ItemStatusID
--------         ------           ------------
 1                22                 4
 1                23                 4
 2                11                 4
 2                12                 3
 2                13                 3

POIndent:

       POID             IndentID     ItemID      ItemStatusID
      --------           ------      ------      ------------
         1                1            22            4
         1                1            23            4
         1                2            11            4

I want to Update IndentHeader table StatusID = 4 when all the Items in the IndentDetail table (based on the IndentID) ItemstatusID becomes 4 otherwise I want to Update IndentHeader StatusID = 3. In the Condition I need to give POID. Based on the POID, the corresponding Indent is considered for both the IndentHeader and IndentDetail table. My desired Result should be like this:

IndentHeader:

 IndentID        StatusID 
--------         ------   
    1             4      
    2             3

How to achieve this? Please help me.

Hi all, this is my update command. But it update both the StatusID in IndentHeader as 4.

   UPDATE STR_IndentHeader
            SET StatusID = IID
            FROM
            (SELECT 
            STR_IndentDetail.IndentID, MIN(ItemStatusID) AS 'IID'
            FROM 
            STR_IndentDetail INNER JOIN PUR_POIndent PP
            ON PP.IndentID = STR_IndentDetail.IndentID
            AND PP.ItemID = STR_IndentDetail.ItemID
                        WHERE ItemStatusID = 4 AND PP.POID = 1
            GROUP BY STR_IndentDetail.IndentID) ID 
            WHERE ID.IndentID = STR_IndentHeader.IndentID 

I need all your valuable contributions. please help me…

My [revised] solution use one ALL subquery to check ItemStatusID condition:

DECLARE @MyPOID INT = 1;

DECLARE @IndentHeader TABLE
(
    IndentID INT PRIMARY KEY
    ,StatusID INT NOT NULL
);
INSERT  @IndentHeader 
VALUES  (1,5);
INSERT  @IndentHeader 
VALUES  (2,5);
INSERT  @IndentHeader 
VALUES  (3,5);

DECLARE @IndentDetail TABLE
(
    IndentID INT NOT NULL
    ,ItemID INT NOT NULL
    ,ItemStatusID INT NOT NULL
    ,PRIMARY KEY(IndentID, ItemID)
);
INSERT  @IndentDetail
VALUES  (1,22,4);
INSERT  @IndentDetail
VALUES  (1,23,4);
INSERT  @IndentDetail
VALUES  (2,11,4);
INSERT  @IndentDetail
VALUES  (2,12,3);
INSERT  @IndentDetail
VALUES  (2,13,3);
INSERT  @IndentDetail
VALUES  (3,22,3);

DECLARE @POIndent TABLE
(
    POID INT
    ,IndentID INT NOT NULL
    ,ItemID INT NOT NULL
    ,ItemStatusID INT NOT NULL
);
INSERT  @POIndent 
VALUES  (1,1,22,4);
INSERT  @POIndent 
VALUES  (1,1,23,4);
INSERT  @POIndent 
VALUES  (1,2,11,4);
INSERT  @POIndent 
VALUES  (2,3,22,4);

SELECT  *
FROM    @IndentHeader h;
SELECT  *
FROM    @IndentDetail d;
SELECT  *
FROM    @POIndent po;

UPDATE  @IndentHeader 
SET     StatusID = CASE WHEN 4 = ALL(SELECT d.ItemStatusID FROM @IndentDetail d WHERE d.IndentID = h.IndentID) THEN 4 ELSE 3 END
FROM    @IndentHeader h
WHERE   h.IndentID IN (SELECT po.IndentID FROM @POIndent po WHERE po.POID = @MyPOID);

SELECT  *
FROM    @IndentHeader h;
