How To

How to Transfer Tables without Constraints and Indexes

Sometime you do not need to move constraints and indexes into the target database. For example, in case when you move data for reporting purpose, or if you want to migrate constraints and indexes later.

Edit sqldata.cfg configuration file, and set -constraints=no and -indexes=no.
