14.13.8 Union of PGX Frames

You can join two PgxFrames that have compatible columns (i.e. same type and order).

• JShell
• Java

opg4j> <first-frame>.union(<secondframe>).print()

<first-frame>.union(<secondframe>).print();

The rows of the resulting PgxFrame are the union of the rows from the two original frames.

Note:

The union operation will not remove duplicate rows that resulted from the union operation.
