Join

org.andl.ra version 1.0.0.202004072326 by andl

Outputs the natural join of two relations (tables) where attributes (columns) are matched by name. Matching attributes must be of the same type.

There is no outer join, tuples (rows) that do not match are dropped from the output. Optionally the output may be restricted to just the attributes of the left hand relation (semijoin), or the inverse of that (antijoin).

Options

Join: Output tuples contain all attributes from both inputs.
Semijoin: Output tuples from the left relation that match a tuple from the right relation.
Antijoin: Output tuples from the left relation that DO NOT match a tuple from the right relation.

Input Ports

: The left (top) input relation.
: The right (bottom) input relation.

Output Ports

: The output relation resulting from the join.
