## Summary - tokenize predicates with the same GenericDialect lexical rules Lance delegates to - rewrite only SQL-standard double-quoted identifier tokens to Lance backticks - apply one predicate contract to query, count, update, delete, and both merge conditions - cover mixed-case identifiers, ordinary literals, comments, and every filter-bearing table operation ## Root cause Lance plans double-quoted tokens as string literals for compatibility. As a result, `"PartyAbbrev" = 'D'` compared two literals and silently evaluated to false instead of filtering the mixed-case column. ## Validation - `cargo fmt --all -- --check` - `cargo test --locked --quiet --features remote -p lancedb expr::sql::tests` - `cargo test --locked --quiet --features remote -p lancedb test_double_quoted_predicates_across_table_operations` - `cargo check --quiet --features remote --tests --examples` - `cargo clippy --quiet --features remote --tests --examples` Fixes #2057 <!-- lance-gatekeeper-fix:v1 agent=a44b6567cfd8890abb4f7395ff71971a generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io>

- Windows (x86_64 and aarch64)
Usage
Basic Example
import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
{ id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
{ id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);
The quickstart contains more complete examples.
