A column map is a map that defines the specifications
for mapping columns of compatible data between source and destination
tables.
A table map can reference a column map to complete the following
tasks:
- Map a source column to a destination column that has a different
name
- Transform source column values before inserting them into destination
columns
- Bypass processing for specific columns
A Column Map Procedure facilitates data transformations in a
process that are beyond the scope of Column Map functions.
