Table and Column Constraint Limitations
Identity Constraints
Sybase supports identity columns, but none of its attributes.
The DB Access Module for Sybase therefore ignores any identity attributes set on an
RWDBIdentityConstraint
object while creating tables.
When fetching a table schema, an identity column will have a valid
RWDBIdentityConstraint
object, but it will have no attributes set on it.
