Fixes #13546 # Description Previously, outer joins would remove rows without join columns, since the "did not match" logic only executed when the row had the join column. To solve this, missing join columns are now treated the same as "exists but did not match" cases. The logic now executes both when the join column doesn't exist and when it exists but doesn't match, ensuring rows without join columns are preserved. If the join column is not defined at all, the previous behavior remains unchanged. Example: ``` For the tables: let left_side = [{a: a1 ref: 1} {a: a2 ref: 2} {a: a3}] let right_side = [[b ref]; [b1 1] [b2 2] [b3 3]] Running "$left_side | join -l $right_side ref" now outputs: ╭───┬────┬─────┬────╮ │ # │ a │ ref │ b │ ├───┼────┼─────┼────┤ │ 0 │ a1 │ 1 │ b1 │ │ 1 │ a2 │ 2 │ b2 │ │ 2 │ a3 │ │ │ ╰───┴────┴─────┴────╯ ``` # User-Facing Changes The ```join``` command will behave more similarly to SQL-style joins. In this case, rows that lack the join column are preserved. # Tests + Formatting Added 2 test cases. fmt + clippy OK. # After Submitting I don't believe anything is necessary. |
