Hi,

Is a way to define DEFAULT, NOT NULL and REFERENCES for members of composite type?

--------------------/Original Message---------------

The only way to constrain a Type is to use a DOMAIN but whether you can domain a composite type I do not know.

There is no concept of "Foreign Key" when it comes to Types, only Tables.
