dm_pack_tbl()

Description

dm_pack_tbl() converts a parent table to a packed column in its child table. The parent table should not have parent tables itself (i.e. it needs to be a terminal parent table).

Usage

dm_pack_tbl(dm, parent_table, into = NULL)

Arguments

dm	A dm.
parent_table	A terminal table with one child table.
into	The table to pack parent_tables into, optional as it can be guessed from the foreign keys unambiguously but useful to be explicit.
