HJoin Tables

../../../../../_images/hjoin_table.svg

The operation of horizontal join, or HJoin, stacks the columns in the incoming Tables horizontally beside each other. The outgoing Table will have all the columns from all the incoming Tables. Note that all Tables that should be hjoined must have the same number of rows.

If a column name exists in both inputs the latter Table (or lower port) will take precedence and the corresponding column from the former Table (or upper port) will be lost.

The node always tries to give the output table a name, so if the chosen port has a table without name, the other port will be used. This is to preserve backwards compatibility.

class node_hjoin_tables.HJoinTablesSingle[source]

Horizontal join of all incoming Tables into a single outgoing Table. Columns from Tables later in the list will take precedence in the case when a certain column name exists in two or more Tables.

Opposite node:

Inputs:
port1
: [table]
