テーブルに挿入するレコードがない場合、+30の更新用PREMIUM_SERVICE_USERのレコードが存在するかどうかを テーブルで確認したい。strClientIDtimeValidstrClientIDpremium_service_user

私は何を間違っていますか？

timeValid+30 日間増加しますが、別の行も挿入されます。

SELECT @pre_var = count(*) 
FROM PREMIUM_SERVICE_USER 
WHERE strClientID = @strClientID

/* bronze premium - 200 cash */
IF @Premium = 1
BEGIN
    INSERT INTO PREMIUM_SERVICE_USER 
        (strClientID, timeReg, timeValid, bCurrent, durum) 
    VALUES 
        (@strClientID,getdate(),getdate() + 30,'1','1')

    UPDATE TB_USER 
    SET cash = cash+200 
    WHERE strAccountID = @strClientID
END

IF @Premium = 1 AND @pre_var = 1
BEGIN
    UPDATE PREMIUM_SERVICE_USER 
        SET timevalid = timevalid+30 where strClientID = @strClientID
    UPDATE PREMIUM_SERVICE_USER 
        SET bCurrent = 1 where strClientID = @strClientID
    UPDATE TB_USER 
        SET cash = cash+200 WHERE strAccountID = @strClientID
END

あなたの問題はif、の値に関係なく最初に実行されていました@pre_var。

これは少し異なる方法で、 が大きい場合に少し効率的になりますPREMIUM_SERVICE_USER。

if @Premium = 1
  begin
    if exists(Select 1 From PREMIUM_SERVICE_USER Where strClientID = @strClientID)
      BEGIN
        update PREMIUM_SERVICE_USER set timevalid = timevalid+30 where strClientID = @strClientID
        update PREMIUM_SERVICE_USER set bCurrent = 1 where strClientID = @strClientID
        UPDATE TB_USER SET cash = cash+200 WHERE strAccountID = @strClientID
       END
    ELSE
      BEGIN
        INSERT INTO PREMIUM_SERVICE_USER (strClientID, timeReg, timeValid, bCurrent, durum) VALUES (@strClientID,getdate(),getdate() + 30,'1','1')
        UPDATE TB_USER SET cash = cash+200 WHERE strAccountID = @strClientID
       END
  end

行を数えていますが、意思決定には使用していません。これは役に立つかもしれない決定構造です

Select @pre_var = count(*) From PREMIUM_SERVICE_USER Where strClientID = @strClientID

IF @pre_var = 0
BEGIN
    /* Run Insert Code Here */
END
ELSE
BEGIN
    /* Run Update Code Here */
END


IF @Premium = 1 
BEGIN
    /* Run Premier Members Update Code Here */
END
ELSE
BEGIN
    /* Run Non-Premier Members Update Code Here */
END

それともこれ..

IF @pre_var = 0
BEGIN
    /* Run Insert Code Here */
END
ELSE
BEGIN
    IF @Premium = 1 
    BEGIN
        /* Run Premier Members Update Code Here */
    END
    ELSE
    BEGIN
        /* Run Non-Premier Members Update Code Here */
    END
END

最初の IF ステートメントで間違った変数をチェックしているようです。@Premium = 1 の場合、この動作が見られます。

/* bronze premium - 200 cash */
IF @pre_var = 0
BEGIN
INSERT INTO PREMIUM_SERVICE_USER (strClientID, timeReg, timeValid, bCurrent, durum) VALUES (@strClientID,getdate(),getdate() + 30,'1','1')
UPDATE TB_USER SET cash = cash+200 WHERE strAccountID = @strClientID
END

IF @Premium = 1 AND @pre_var = 1
BEGIN
update PREMIUM_SERVICE_USER set timevalid = timevalid+30 where strClientID = @strClientID
update PREMIUM_SERVICE_USER set bCurrent = 1 where strClientID = @strClientID
UPDATE TB_USER SET cash = cash+200 WHERE strAccountID = @strClientID
END
