OXY-165: Add LIKE / ILIKE predicate support to the oxygen-sql query DSL - #305

Add `like` / `ilike` / `notLike` / `notILike` string-pattern predicates, usable in `where if ...` on String columns. The pattern binds as a single scalar String param, so the generated SQL stays static (`col LIKE ?`). These slot in as new `BinOp.Comp` cases; the rest of the pipeline (RawQueryExpr / QueryExpr / FragmentBuilder) is generic over `Comp`, so no other production code changes were needed. - BinOp: LIKE / ILIKE / NOT LIKE / NOT ILIKE cases - Q.scala: string extension methods - it-test: @compile queries + real-Postgres CustomQuerySpec test (wildcards, case-sensitivity, negation, composition) - docs/sql/queries.md ILIKE / NOT ILIKE are Postgres-specific (fine while PG-only).

OXY-165 — Add LIKE / ILIKE predicate support to the oxygen-sql query DSL
Adds
LIKE/ILIKE(case-insensitive) string-pattern predicates — plus their negations — to the@compilequery DSL, usable inwhere if ...onStringcolumns. The pattern binds as a single scalarStringparam, so the generated SQL stays static (col LIKE ?/col ILIKE ?).How it fits
Per the OXY-163 roadmap, the DSL's binary-operator extension points are generic. These slot in purely as new
BinOp.Compcases — the rest of the pipeline (RawQueryExpr,QueryExpr,FragmentBuilder) is generic overComp, so no other production code changed. Thequery-var op input-varpath already emitscol <op> ?and binds the input using the LHS column'sRowRepr.DSL surface
On
Stringcolumns:col.like(pattern)→col LIKE ?col.ilike(pattern)→col ILIKE ?(Postgres-specific)col.notLike(pattern)→col NOT LIKE ?col.notILike(pattern)→col NOT ILIKE ?(Postgres-specific)Changes

ILIKE/NOT ILIKEare Postgres-specific — acceptable while oxygen-sql is PG-only; flagged for the future Dialect seam.🤖 Generated with Claude Code
