SQL Trigger Syntax

I have this trigger: -
    UPDATE dbo.InvMaster
       SET StockOnHold = 'F'
         , StockOnHoldReason = 'NEW'    
     WHERE StockCode in (SELECT StockCode FROM Inserted);

Open in new window


One of the fields inserted is 'WarehouseToUse' (Char(2)),  If the entry in this field is 'B ' I don't want the trigger to fire. Does anyone know the syntax?

You can't stop the trigger firing but you can put an if statement around it.

if exists(select WarehouseToUse from inserted where WarehouseToUse <> 'B')
begin
    UPDATE dbo.InvMaster
       SET StockOnHold = 'F'
         , StockOnHoldReason = 'NEW'    
     WHERE StockCode in (SELECT StockCode FROM Inserted)
end

If WarehouseToUse field is in table InvMaster:
UPDATE dbo.InvMaster
       SET StockOnHold = 'F'
         , StockOnHoldReason = 'NEW'    
     WHERE StockCode in (SELECT StockCode FROM Inserted)
       AND WarehouseToUse <> 'B '
 ;

Open in new window


If WarehouseToUse field is in the Inserted on (and it's different from the InvMaster table :
UPDATE dbo.InvMaster
       SET StockOnHold = 'F'
         , StockOnHoldReason = 'NEW'    
     WHERE StockCode in (SELECT StockCode FROM Inserted WHERE WarehouseToUse <> 'B ');
