`jooqx` leverages the power of typesafe SQL from https://www.jooq.org[jOOQ DSL] and uses the reactive and non-blocking `SQL driver` from https://vertx.io/docs/#databases[Vert.x]

== Examples

[source,java,subs="attributes,verbatim"]

----

// Vertx part: Init Postgres client

PgConnectOptions connectOptions = new PgConnectOptions()                                <1>

  .setPort(5432)

  .setHost("the-host")

  .setDatabase("the-db")

  .setUser("user")

  .setPassword("secret");

PoolOptions poolOptions = new PoolOptions().setMaxSize(5);                              <2>

PgPool pgPool = PgPool.pool(connectOptions, poolOptions);                               <3>

// jOOQ part: Init DSL context

DSLContext dsl = DSL.using(new DefaultConfiguration().set(SQLDialect.POSTGRES));        <4>

Authors table = Tables.AUTHORS;                                                         <5>

// jooqx part: Enjoy moment

Jooqx jooqx = Jooqx.builder().setVertx(vertx).setDSL(dsl).setSqlClient(pgPool).build(); <6>

jooqx.execute(

    dsl -> dsl.select().from(table).where(table.COUNTRY.eq("VN"),                       <7>

    DSLAdapter.fetchOne(table, Collections.singletonList(table.ID, table.NAME),         <8>

    ar ->  System.out.println(ar.result())                                              <9>

----

<1> Create `Vertx` PostgreSQL connection options

<2> Create `Vertx` SQL pool options

<3> Init `Vertx` https://vertx.io/docs/vertx-pg-client/java/[PostgreSQL pool client]

<4> Init `jOOQ` DSL context with `Postgres` dialect

<5> The example table is generated by `jOOQ` https://www.jooq.org/doc/latest/manual/getting-started/tutorials/jooq-in-7-steps/jooq-in-7-steps-step3/[codegen]

<6> Init `jooqx` instance by builder

<7> First arg: The https://docs.oracle.com/javase/8/docs/api/java/util/function/Function.html[function] produces `jOOQ` https://www.jooq.org/doc/latest/manual/getting-started/tutorials/jooq-in-7-steps/jooq-in-7-steps-step5/[Query] by DSL context

<8> Second arg: the jooqx https://zero88.github.io/jooqx/jooqx/main/features-result-adapter.html[result adapter] to convert `Vertx` SQL result to typesafe record in `jOOQ`

<9> Third arg: just simple async future handler
