Table and Column Mapping
If no column mapping is specified during the register as link statement, data is promoted from the local database’s iicolumns to Ingres Star’s iicolumns.
The local information is stored in the Ingres Star-specific catalog iiddb_ldb_columns. The representation in iiddb_ldb_columns is used exclusively by Ingres Star.
The column information of the registered name is stored in Ingres Star’s iicolumns standard catalog.
Ingres Star provides column mapping if either the distributed database or the local database (but not both) support mixed-case delimited identifiers.
