我有一个触发器，它在将记录插入表后执行。触发器基本上，调用一个函数并将值从插入传递到它。但是，虽然它有时有效，但我也不断收到以下错误：

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

我一直在玩它一段时间，但似乎无法解决这个问题，特别是考虑到它有时会起作用。

将函数的参数更改为 FLOAT，而不是两个参数的 INT。
