New domain

To create a new domain open a database, select the Domains tab and click on Main Menu-Object-New, or the create object button on the database tool bar.

You must enter the domain name and the base type.

You can set the size, default values, check constraints, character set, collation orders and create array types by filling the array dimensions table.

Be aware that once a domain is created some options can not change:

  1. Not null
  2. Character set and collation order
  3. Array dimensions
  4. Segment size for blobs

Other domain options can change with limitations

  1. The size of char/varchar fields can be changed if thre is not string truncation.
  2. Warning adding check constraints can result on invalid data.
