Control Structures¶

branch¶

If the test expression returns False or None, the false_branch will be evaluated. Otherwise, the true_branch will be evaluated.

The branch command is effectively an if renamed due to language constraints.

Example: Return heroes and superheroes.

r.table("marvel").map(
    r.branch(
        r.row().field("victories").gt(100),
        r.row().field("name").add(" is a superhero"),
        r.row().field("name").add(" is a hero")
    )
).run(conn)
