i5/OS database query

 

The database interactive query function, provided by the i5/OS^® licensed program, supports DDM files.

This support is used by iSeries™ Access Family and System/38™-compatible query utility if OPTIMIZE(*YES) is specified. You can query remote files using the Open Query File (OPNQRYF) command, but only if the remote files are on a target iSeries server or a target System/38.

The query utility on the System/38 can be used to query remote files that are not from an iSeries server.

• Multiple remote files
  Database query allows accessing of either multiple local files or multiple remote files (by using DDM files) at the same time, but not both.
