跨数据库SQL触发器史诗失败

Question

I have the below SQL Trigger on a SQL 2005 box that is supposed to help me replicate certain Person Info to another database to be used for Reporting and various other things as a reference.

I have 1 DB named Connect which is where the current app manipulates the Person Data on tblPerson. I have another DB, on same physical box, named MATRIX where a new app manipulates it's Data. I am trying to build a Table in MATRIX called tblIdentificationMap that simply stores all of the various ID's we have from the different apps in house.

When I enable this Trigger and try to update tblPerson I get the following error --> Msg 208, Level 16, State 1, Procedure tblPersonIDMap_OnUpdate, Line 15 Invalid object name 'MATRIX.dbo.tblIndentificationMap'.

This is my UPDATE statement -->

`  use Connect
  update tblPerson
  set MiddleName = 'Fakey'
  where PersonID = 258243`

And this is my Trigger -->

ALTER TRIGGER [dbo].[tblPersonIDMap_OnUpdate] 


ON  [dbo].[tblPerson] 
   AFTER UPDATE
AS 
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;





UPDATE MATRIX.dbo.tblIndentificationMap
        SET     m.PersonID = i.PersonID
                ,m.FirstName = i.FirstName
                ,m.MiddleName = i.MiddleName
                ,m.LastName = i.LastName

    FROM MATRIX.dbo.tblIdentificationMap m, inserted i, deleted d
    WHERE d.PersonID = m.PersonID
END

Replace

UPDATE MATRIX.dbo.tblIndentificationMap

with

m

in the first line. Also in the SET area you don't need the references to m (although I don't think they do any harm, it makes it a smidgeon harder to maintain).

Your SET statement is confused as you're inconsistently referring to the alias and the real name.
