Treats an object as nondeterministic

Example

At the unityadmin prompt:

Input Result
OBJECT SET DETERMINISM databasename.objectname FORCE NONDETERMINISTIC; Forces Unity to use CDM replication for SQL statements which
  • Perform a write; and
  • Reference the named object
OBJECT SET DETERMINISM databasename.objectname FORCE DETERMINISTIC; Forces Unity to not use CDM replication due to the named object being referenced in the SQL statement. This does not guarantee that the SQL statement will not result in CDM replication due to the determinism level of other objects referenced within the same SQL statement.
OBJECT SET DETERMINISM databasename.objectname NO OVERRIDE; Allows Unity to decide which replication type to use in regards to the named object being referenced within a SQL statement.
