Support the LIKE and NOT LIKE operators.

The .like. and .notLike binary operators now work.

Enum Support

Adds support for using SQL enums natively. There are three different levels of support:

• typeName: Postgres-like, has CREATE TYPE ... AS ENUM syntax
• inline: MySQL-like, has ENUM(...) data type
• unsupported: SQLite-like, no enum support.

Supported enum syntax is available via SQLDialect.enumSyntax. This can be used to conditionally run code depending on database support.

A new test case SQLBenchmarker.testEnum has been added that tests the following on all three databases:

• Create table with enum column
• Add new value to enum
• Drop value from enum

Note: Dropping enum values from Postgres-like DBs is not supported.

Here is the raw SQL output from the benchmark for each database:

SQLite

CREATE TABLE "planets"("id" BIGINT PRIMARY KEY, "name" TEXT NOT NULL, "type" TEXT NOT NULL) []
INSERT INTO "planets" ("name", "type") VALUES (?, 'smallRocky'), (?, 'gasGiant') ["Earth", "Jupiter"]
INSERT INTO "planets" ("name", "type") VALUES (?, 'dwarf') ["Pluto"]
DELETE FROM "planets" WHERE "type" = 'gasGiant' []
DROP TABLE "planets" []

Postgres

CREATE TYPE "planet_type" AS ENUM ('smallRocky', 'gasGiant') []
CREATE TABLE "planets"("id" BIGINT PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY, "name" TEXT NOT NULL, "type" "planet_type" NOT NULL) []
INSERT INTO "planets" ("name", "type") VALUES ($1, 'smallRocky'), ($2, 'gasGiant') ["Earth", "Jupiter"]
ALTER TYPE "planet_type" ADD VALUE 'dwarf' []
INSERT INTO "planets" ("name", "type") VALUES ($1, 'dwarf') ["Pluto"]
DELETE FROM "planets" WHERE "type" = 'gasGiant' []
DROP TABLE "planets" []
DROP TYPE "planet_type" []

MySQL

Opening new connection to [IPv6]localhost/::1:3306
CREATE TABLE `planets`(`id` BIGINT PRIMARY KEY AUTO_INCREMENT, `name` TEXT NOT NULL, `type` ENUM('smallRocky', 'gasGiant') NOT NULL) []
INSERT INTO `planets` (`name`, `type`) VALUES (?, 'smallRocky'), (?, 'gasGiant') ["Earth", "Jupiter"]
ALTER TABLE `planets` MODIFY `type` ENUM('smallRocky', 'gasGiant', 'dwarf') []
INSERT INTO `planets` (`name`, `type`) VALUES (?, 'dwarf') ["Pluto"]
DELETE FROM `planets` WHERE `type` = 'gasGiant' []
ALTER TABLE `planets` MODIFY `type` ENUM('smallRocky', 'dwarf') []
DROP TABLE `planets` []
