    2. COHi, sorry it has taken so long to reply. I tried out your code above and it works. However, when I try to use it with one of our real temp tables created with `select * from myTable into temp TmpMyTable with no log` I get errors of `Error Code: -9930, Byte, Text, Serial, Serial8 or Bigserial datatypes in collection types not allowed.` We use serial in a lot of tables so it looked promising but not right for my situation. I take it the undocumented function is the 'collectionoutput'? I may take this question to the IIUG list for more ideas. Thanks, Bryce.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
