我有一个触发器,它在将记录插入表后执行。触发器基本上调用一个函数并将插入值传递给它。但是,虽然它有效,但我也一直收到以下错误:
Msg 8115, Level 16, State 2, Procedure UpdateNabersRating, Line 17
Arithmetic overflow error converting expression to data type int.
触发器如下:
UPDATE BMS_Snapshot SET
NABERS = dbo.SetmetricsNABERSCalculation(
60,
tbl.NetFloorArea,
tbl.ElectricityCumulative,
tbl.GasCumulative,
tbl.ElectricityCumulativeMax,
tbl.GasCumulativeMax,
tbl.ElectricityMaxTotal,
tbl.GasMaxTotal,
tbl.NaturalGasConversionCubicMetersToMJ,
tbl.SuburbId)
FROM
(SELECT
Snap.SnapshotId AS SnapshotId,
Snap.ElectricityCumulative AS ElectricityCumulative,
Snap.GasCumulative AS GasCumulative,
Building.NetFloorArea AS NetFloorArea,
Building.NABERSElecTotalMax AS ElectricityMaxTotal,
Building.NABERSGasTotalMax AS GasMaxTotal,
Building.NABERSExpiry As Expiry,
NABERSTarget.ElecCumulativeMax AS ElectricityCumulativeMax,
NABERSTarget.GasCumulativeMax AS GasCumulativeMax,
[State].NaturalGasConversionCubicMetersToMJ AS NaturalGasConversionCubicMetersToMJ,
Suburb.SuburbId AS SuburbId
FROM inserted AS Snap
INNER JOIN AST_Building AS Building ON Snap.BuildingId = Building.BuildingId
INNER JOIN ESD_Suburb AS Suburb ON Building.SuburbId = Suburb.SuburbId
INNER JOIN ESD_State AS [State] ON Suburb.StateId = [State].StateId
INNER JOIN AST_NABERSTarget NABERSTarget ON Snap.BuildingId = NABERSTarget.BuildingId AND
Snap.TimeStamp = NABERSTarget.Timestamp
/*Where Snap.SnapshotId IN (Select inserted.SnapshotId FROM inserted)*/) AS tbl
WHERE tbl.SnapshotId = BMS_Snapshot.SnapshotId AND BMS_Snapshot.Range = 1
我已经玩了一段时间,但似乎无法解决问题,特别是考虑到它有时会起作用。
答案 0 :(得分:2)
将函数的参数更改为FLOAT,而不是两个参数的INT。
