Issue During Update And Insert (trigger Problems)

Hello,

I have created a job that fill and update a database from a source db with same structure.

INSERT code is made up comparing the pk column in the source and dest db, the missed ones are filled in the destination.

UPDATE: check col by col, if any change value exists, updated is performed with the following statement for any tables in the DB

UPDATE tableADest

SET col1=source.Col1, col2=source.col2, ... coln=source.coln

FROM tableASource source

INNER JOIN tableAdest dest

ON dest.colpk = source.colpk

The main problem is that I cannot identify the row update in the souce db, everytime I have to compare the whole equivalent tables (source and dest db), because there are not timestamp, updated cols or any cols usefuls, to have a subset of data and find any new or upadeted rows.

I tried replication, but it does not work on that db.

So I created a trigger for each table where new insert or updated row must be detected. The PKs are saved on tables.

The problem is that when I run the application it hold-on, when triggers are disabled the application run fine.


How can I use trigger on several tables without affectrunning application?



Thank
