Question

任何人都可以请指出我在这个存储过程中做错了。我无法编译它，我的软件没有提供任何有用的线索，说明它有什么问题。

CREATE PROCEDURE web.createSubscriptions
   (
   @Member_Id BIGINT,
   @Trans_type VARCHAR(100),
   @Payment_Status VARCHAR(100),
   @Payment_Date DATETIME,
   @Trans_Id VARCHAR(100)
   )

AS
DECLARE @tmpType VARCHAR(15)
BEGIN

INSERT INTO TBL_SUBSCRIPTIONS (subs_MemberID, subs_Type, subs_Status, subs_DateGenerated, subs_PaypalTransaction) VALUES(@Member_Id, @Trans_Type, @Payment_Status, @Payment_Date, @Trans_Id)

IF(@Trans_type = 'subscr_signup')
    BEGIN
    @tmpType = 'premium'
    END
ELSE(@Trans_type = 'subscr_cancel')
    BEGIN
    @tmpType = 'basic'
    END

UPDATE TBL_MEMBERS
SET members_Type = @tmpType
WHERE members_Id = @Member_Id

END

Answer 1

尼克是对的。下一个错误是else应该是else if（你当前在你的else中有一个布尔表达式没有意义）。这应该是什么

ELSE IF(@Trans_type = 'subscr_cancel')
    BEGIN
    SET @tmpType = 'basic'
    END

您目前有以下内容（错误）：

ELSE(@Trans_type = 'subscr_cancel')
    BEGIN
    SET @tmpType = 'basic'
    END

这是未来的提示 - 双击错误，SQL Server Management Studio将转到错误所在的行。如果您认为SQL Server会出现神秘错误（我认为它没有），那么您还没有使用过Oracle！

Answer 2

它没有给出任何错误？尝试
SET @tmpType = 'premium“
和
SET @tmpType = 'basic'

Answer 3

在IF .. ELSE块中分配变量时，是否缺少'SET'语句？

Answer 4

尝试

set @tmptype

Answer 5

是的尼克是对的。

您需要使用SET或SELECT分配给@tmpType

Answer 6

只是提示，如果它只包含一个语句，则不需要BEGIN和END。

即：

IF(@Trans_type = 'subscr_signup')    
 set @tmpType = 'premium' 
ELSE iF(@Trans_type = 'subscr_cancel')  
     set    @tmpType = 'basic'

Answer 7

使用SQL连接语句尝试此操作

CREATE PROCEDURE [dbo].[deleteItem]
   @ItemId int = 0  
 AS
 Begin
 DECLARE @cnt int;

SET NOCOUNT ON
SELECT @cnt =COUNT(ttm.Id) 
    from ItemTransaction itr INNER JOIN ItemUnitMeasurement ium 
        ON itr.Id = ium.ItemTransactionId  INNER JOIN ItemMaster im 
        ON itr.ItemId = im.Id INNER JOIN TransactionTypeMaster ttm 
        ON itr.TransactionTypeMasterId = ttm.Id 
        where im.Id = @ItemId

if(@cnt = 1)
    Begin
    DECLARE @transactionType varchar(255);
    DECLARE @mesurementAmount float;
    DECLARE @itemTransactionId int;
    DECLARE @itemUnitMeasurementId int;

        SELECT @transactionType = ttm.TransactionType,  @mesurementAmount = ium.Amount, @itemTransactionId = itr.Id, @itemUnitMeasurementId = ium.Id
        from ItemTransaction itr INNER JOIN ItemUnitMeasurement ium 
            ON itr.Id = ium.ItemTransactionId INNER JOIN TransactionTypeMaster ttm 
            ON itr.TransactionTypeMasterId = ttm.Id 
            where itr.ItemId = @ItemId  
        if(@transactionType = 'Close' and @mesurementAmount = 0)
            Begin
                delete from ItemUnitMeasurement where Id = @itemUnitMeasurementId;

            End
        else
            Begin
                delete from ItemTransaction where Id = @itemTransactionId;
            End
    End
else
 Begin
    delete from ItemMaster where Id = @ItemId;
 End

END

Answer 8

试

IF(@Trans_type = 'subscr_signup')    
BEGIN 
 set @tmpType = 'premium' 
 END
ELSE iF(@Trans_type = 'subscr_cancel')  
  begin
     set    @tmpType = 'basic'  
  END
