#generated? ⇒ Boolean

The only means that Oracle currently provides for auto-generating a column is to define a sequence and a trigger on insert that inserts sequence.nextval

As a result of this, there is no reliable way to determine whether a particular column is generated by the DB.

DrySQL currently makes the assumption that a column is auto-generated if the column is of type integer and is the primary key for the table

Ideally a future release of Oracle will support declaring a default value of sequence.nextval for a column, which will eliminate this problem.

Returns:

  • (Boolean)
