Prior to this PR, the less/greater than operators (`<`, `>`, `<=`, `>=`) would throw an error if either side was null. After this PR, these operators return null if either side (or both) is null. ### Examples ```bash 1 < 3 # true 1 < null # null null < 3 # null null < null # null ``` ### Motivation JT [asked the C# folks](https://discord.com/channels/601130461678272522/615329862395101194/1086137515053957140) and this is apparently the approach they would choose for comparison operators if they could start from scratch. This PR makes `where` more convenient to use on jagged/missing data. For example, we can now filter on columns that may not be present in every row: ``` > [{foo: 123} {}] | where foo? > 10 ╭───┬─────╮ │ # │ foo │ ├───┼─────┤ │ 0 │ 123 │ ╰───┴─────╯ ``` |
