RepAgent selects as the primary key:
- The primary index defined on a table, or
- A unique index with the lowest index identifier if there is no primary index
Note: If there is no primary key or unique index defined on the table, RepAgent does not send primary key information to the LTL. If the table does not have a replication definition, Replication Server treats all columns in the table, except text, image, or unitext columns, as primary key columns. This can degrade replication performance for the table.
