Inserting and Retrieving UDTs with Client Products
A UDT can only exist on the Teradata Database server. Each UDT has an associated “from‑sql
routine” and “to‑sql routine”.
“insert – The “to‑sql routine” constructs a UDT value from a pre‑defined type value.
The “to‑sql routine” is automatically invoked when inserting values from a client
system into a UDT on the Teradata Database server.
Retrieve – The “from‑sql routine” generates a pre‑defined type value from a UDT. The
“from‑sql routine” is automatically invoked when a UDT is retrieved from the Teradata
Database server to a client system.
