Expand description

Comparison / membership operators (query-builder.ts simpleConditionToSQL). Most lower to their raw SQL spelling verbatim; In/NotIn lower to a json_each(?) subquery over a JSON-array literal (query-builder.ts:196-205); the Like family appends ESCAPE '\' and Ilike lowers both sides through lower(...) (query-builder.ts likeConditionToSQL). Is/IsNot are the NULL-aware equality operators in the JS SimpleOperator set (ast.ts:37): they reach the WHERE verbatim (a user .where(c, 'IS', null), and the engine’s NOT EXISTSfield IS NOT literal rewrite, resolve-scalar-subqueries.ts:176). Distinct from the start-bound’s nullable-aware =/IS choice (§3.7), which is a SEPARATE code path keyed on column optionality, not a user operator.

impl PartialEq for SqlOp

Source§

fn eq(&self, other: &SqlOp) -> bool
