写了个简单函数，报一大串错误，求解

CREATE FUNCTION w_getPushMonet(@userId VARCHAR(40),@yeji MONEY) RETURNS MONEY
AS 
BEGIN
DECLARE @job VARCHAR
DECLARE @unit VARCHAR
DECLARE @rate DOUBLE
DECLARE @minMoney DOUBLE
DECLARE @maxMoney DOUBLE
SELECT @job=JobTitle,@unit=BusinessUnitId FROM [User] WHERE UserId=@userId
DECLARE temp_ CURSOR FOR 
SELECT c__yjed,c__yjedmax,c__tcxs FROM e__tcgz WHERE c__bm=@unit AND c__gw=@job;
OPEN temp_
FETCH NEXT FROM temp_ INTO @minMoney,@maxMoney,@rate
WHILE(@@FETCH_STATUS=0)
BEGIN 
 IF @maxMoney='' OR @maxMoney IS NULL 
 BEGIN 
IF @yeji>=@minMoney
BEGIN 
 RETURN @rate
 END
END
ELSE IF @minMoney<=@yeji AND @maxMoney>@yeji
BEGIN 
RETURN @rate
END
END
FETCH NEXT FROM temp_ INTO @minMoney,@maxMoney,@rate
CLOSE temp_
DEALLOCATE temp_
END

t-sql没有double类型啊
[解决办法]

CREATE FUNCTION w_getPushMonet(@userId VARCHAR(40),@yeji MONEY) 
RETURNS MONEY
AS 
BEGIN
DECLARE @job VARCHAR(10)
DECLARE @unit VARCHAR(10)
DECLARE @rate BIGINT
DECLARE @minMoney BIGINT
DECLARE @maxMoney BIGINT
SELECT @job=JobTitle,@unit=BusinessUnitId FROM [User] WHERE UserId=@userId
DECLARE temp_ CURSOR FOR 
    SELECT c__yjed,c__yjedmax,c__tcxs FROM e__tcgz WHERE c__bm=@unit AND c__gw=@job;
    OPEN temp_
    FETCH NEXT FROM temp_ INTO @minMoney,@maxMoney,@rate
    WHILE(@@FETCH_STATUS=0)
    BEGIN 
         IF @maxMoney='' OR @maxMoney IS NULL

sql server没有double类型
[解决办法]
改成这样，用float类型：

CREATE FUNCTION w_getPushMonet(@userId VARCHAR(40),@yeji MONEY) RETURNS MONEY
AS 
BEGIN
DECLARE @job VARCHAR(20)
DECLARE @unit VARCHAR(20)
DECLARE @rate float
DECLARE @minMoney float 
 
DECLARE @maxMoney float
SELECT @job=JobTitle,@unit=BusinessUnitId FROM [User] WHERE UserId=@userId

DECLARE temp_ CURSOR FOR 
SELECT c__yjed,c__yjedmax,c__tcxs FROM e__tcgz WHERE c__bm=@unit AND c__gw=@job;
OPEN temp_
FETCH NEXT FROM temp_ INTO @minMoney,@maxMoney,@rate
WHILE(@@FETCH_STATUS=0)
BEGIN 
 IF @maxMoney='' OR @maxMoney IS NULL 
 BEGIN 
IF @yeji>=@minMoney
BEGIN 
 RETURN @rate
 END
END
ELSE IF @minMoney<=@yeji AND @maxMoney>@yeji
BEGIN 
RETURN @rate
END
END
FETCH NEXT FROM temp_ INTO @minMoney,@maxMoney,@rate
CLOSE temp_
DEALLOCATE temp_
END

你没算sqlserver吧？sqlserver从来都没出现过double
[解决办法]

我用SqlDBX自动提示出来的double...

那个可能是oracle的。。。
