Default forward data type mappings
The two kinds of mappings between data source data types and federated database data types are forward type mappings and reverse type mappings. In a forward type mapping, the mapping is from a remote type to a comparable local type.
You can override a default type mapping, or create a new type mapping with the CREATE TYPE MAPPING statement.
These mappings are valid with all the supported versions, unless otherwise noted.
For all default forward data types mapping from a data source to the federated database, the federated schema is SYSIBM.
The following tables show the default forward mappings between federated database data types and data source data types.
