Hello,
i'm trying to execute the following job file :
localhost intranet intranet 3306 intranet localhost extranet extranet 3306 extranet `users` “user_id“ “user_contact“ with sja, all seems to work fine, but on dest db all fields of “users” are copied.
I've tried with sja 4.0 and 4.1.
Any hints ? i followed the sintaxis of the examples in
http://www.webyog.com/sqlyog/sjaschema.html
Thank you !

The behavior is correct.
Specifying column names tells SJA to use those particular columns for generation of checksums. Checksums from source and target tables are then compared to identify a unique row.
Once a unique row has been found, complete row data would be copied from source to target.
Currently there is no way to copy selected columns from source to target.

What about if you change
“user_id“ “user_contact“ to
`user_id` `user_contact` ?

It will be same as SJA checks for extra ` and strips them out.
SJA will always copy whole row from source to target.

Hello,
Is there any way to copy a set of selected columns from source to target as we speak?
Thanks

no way to do that with SJA. We do not plan to implement 'exchanging column data between corresponding rows' either.
What we are considering is a 'row based sync' where some rows can be sync in one direction and others in the other. But still complete rows will be transferred.
