I have 2 databases. One, named Test, has a table named Vehicles. Another, named Test2 has a table named Clients.
When I insert a new record on the Vehicles table in Test, I need to update the NumVehicles field on the Clients table in Test2.
Is this possible using triggers?
You need something like
USE Test;
GO
CREATE TRIGGER afterVehicleInsert ON Vehicles AFTER INSERT
AS
BEGIN
IF @@rowcount = 0 RETURN;
UPDATE Test2.[schema_name(default schema is dbo)].Clients
SET NumVehicles = NumVehicles +1 -- or whatever it should be
FROM Test2.[schema_name(default schema is dbo)].Clients c
INNER JOIN inserted i ON ([your join condition])
END;
GO
The only difference between updating the table in current and another db is that you need to refer a "remote" table using [db_name].[schema_name].[table_name]
This is working code is given below
USE BioStar;
GO
CREATE TRIGGER trgAfterInsertnew ON [dbo].[TB_EVENT_LOG]
FOR INSERT
AS
declare @nDateTime int;
declare @nReaderIdn int;
declare @nEventIdn int;
declare @nUserID int;
declare @nIsLog smallint;
declare @nTNAEvent smallint;
declare @nIsUseTA smallint;
declare @nType smallint;
select @nDateTime=i.nDateTime from inserted i;
select @nDateTime=i.nReaderIdn from inserted i;
select @nEventIdn=i.nEventIdn from inserted i;
select @nUserID=i.nUserID from inserted i;
select @nIsLog=i.nIsLog from inserted i;
select @nTNAEvent=i.nTNAEvent from inserted i;
select @nIsUseTA=i.nIsUseTA from inserted i;
select @nType=i.nType from inserted i;
insert into [HRM].dbo.Device_Data
(nDateTime,nReaderIdn,nEventIdn,nUserID,nIsLog,nTNAEvent,nIsUseTA,nType)
values(@nDateTime,@nDateTime,@nEventIdn,@nUserID,@nIsLog,@nTNAEvent,@nIsUseTA,@nType);
--set @audit_action='Inserted Record -- After Insert Trigger.';
PRINT 'AFTER DELETE TRIGGER fired.'
GO
