Question

我正在针对临时表运行2个SQL语句来进行一些计算。第一个运行良好，但在第二个我收到以下错误，我不知道为什么。

Msg 8115，Level 16，State 8，Line 123
算术溢出错误将数字转换为数据类型数字。

也许你可以看到我失踪的东西。以下是我正在使用的陈述和表格。

声明：

update down
Set AMOUNT = case when (up.id is null) then null else  
case when(abs(down.SHAMT)<abs(up.SHAMT) 
and (down.SHQTY<up.SHQTY or down.SHPU#<up.SHPU#) 
and down.GROUPID is not null) then abs(up.SHAMT)-abs(down.SHAMT)
else case when(abs(down.SHAMT)>abs(up.SHAMT) 
and (down.SHQTY>up.SHQTY or down.SHPU#>up.SHPU#) 
and down.GROUPID is not null) then abs(down.SHAMT)-abs(up.SHAMT) end end end
From #ServiceChange down 
join #ServiceChange up 
on up.id = down.id-1 and up.SHCUST = down.SHCUST 
and up.SHDESC = down.SHDESC
where down.GROUPID in ('SD','SI')

update down
Set AMOUNT= case when (up.id is null) then null else  
case when(abs(down.SHAMT)<abs(up.SHAMT) 
and down.GROUPID is not null) then abs(up.SHAMT)-abs(down.SHAMT)
else case when(abs(down.SHAMT)>abs(up.SHAMT) 
and down.GROUPID is not null) then abs(down.SHAMT)-abs(up.SHAMT) end end end
 From #ServiceChange down 
join #ServiceChange up 
on up.id = down.id-1 and up.SHCUST = down.SHCUST 
and up.SHDESC = down.SHDESC
where down.GROUPID in ('PD','PI')

表：

CREATE TABLE #ServiceChange
(
    [ID] [int] identity(1,1),
    [ORDER] [numeric](8, 0) NOT NULL,
    [SHCOMP] [char](2) NOT NULL,
    [SHCRTD] [numeric](8, 0) NOT NULL,
    [SHCUST] [numeric](7, 0) NOT NULL,
    [SHDESC] [char](35) NOT NULL,
    [SHTYPE] [char](1) NOT NULL,
    [SHAMT] [numeric](9, 2) NOT NULL,
    [SHCRTT] [numeric](6, 0) NOT NULL,
    [SHQTY] [numeric](5, 0) NOT NULL,
    [SHPU#] [numeric](2, 0) NOT NULL,
    [CBLNAM] [char](30) NOT NULL,
    [CSTRDT] [numeric](8, 0) NOT NULL,
    [TBODY] [char](6) NOT NULL,
    [GROUPID] [char](2) NULL,
    [AMOUNT] [numeric](8, 2) NULL
)

如果需要更多信息，请告知我们。

也许是因为您想更新价值为[AMOUNT] [numeric](8, 2)的{{1}}？
