Heya folks,
Recently I've been using a Kotlin library SQLDelight which is great but has some issues with PostgreSQL support. In particular, for null parameters it converts `=` to `IS` - and it treats `IS` as a binary operator (rather than `IS NULL` unary operator), which Postgres doesn't like wrt prepared statements prepare test(text) as (SELECT * FROM test WHERE nullable_col IS $1); ERROR: syntax error at or near "$1" LINE 1: ...epare test(text) as (SELECT * FROM test WHERE nullable_col IS $1);full details at [1] I’ve been working on a PR to use `IS NOT DISTINCT FROM` as the `=` substitution for nullable parameters rather than `IS`, however unfortunately that’s not universally supported either (MySQL). Just wondering if anyone has other ideas? I guess there’s no interest in adding support for `IS` as basically an alias for `IS NOT DISTINCT FROM`? (and `IS NOT` for `IS DISTINCT FROM`) TIA David Wheeler |
