Cross-schema SQL ELT optimization

Cross-schema
SQL ELT optimization

You can use cross-schema
SQL ELT optimization
for a
mapping
task to read from or write data to PostgreSQL objects associated with different schemas within the same PostgreSQL database.
To use cross-schema
SQL ELT optimization
, create two PostgreSQL ODBC connections and specify the schema in each connection. Ensure that the schema in the source connection is different from the schema in the target connection, but both the schemas must belong to the same database. When you configure
SQL ELT optimization
for the
mapping
task, enable cross-schema
SQL ELT optimization
in the advanced session properties. By default, the check box is selected.
