Data Types in Distributed DELETE Operations (IDS)

In Dynamic Server, a DELETE (or any other SQL data-manipulation language statement) that accesses a database of another database server can only reference the built-in data types that are not opaque, DISTINCT, extended, nor large-object types. Cross-server DML operations cannot reference a column or expression of an opaque, DISTINCT, complex, large-object, nor user-defined data type (UDT).

Distributed operations that access other databases of the local Dynamic Server instance, however, can also access most built-in opaque data types, which are listed in BOOLEAN and Other Built-In Opaque Data Types (IDS).

Deletes across databases of the local Dynamic Server instance can also reference UDTs, as well as DISTINCT types based on built-in data types, if all the UDTs and DISTINCT types are explicitly cast to built-in data types, and all the UDTs, DISTINCT types, and casts are defined in each of the participating databases.

Deletes cannot access a database of another database server unless both servers define TCP/IP connections in the DBSERVERNAME or DBSERVERALIAS configuration parameters. This applies to any communication between Dynamic Server instances, even if both database servers reside on the same computer.
