Interface Schema

  • All Superinterfaces:
    Named, QueryPart, Serializable
    All Known Implementing Classes:
    LazySchema, SchemaImpl
    public interface Schema
extends Named
    A schema.

    Standard SQL object identifiers come in 3 parts: [catalog].[schema].[object]. The schema is an object that groups a set of objects, where objects can be Table, Sequence, Routine and many other types of objects.

    If your RDBMS supports schemas, and jOOQ supports using schemas with your RDBMS, then generated schemas references can be used to qualify objects

    Example: 

     // Assuming import static org.jooq.impl.DSL.*;

 using(configuration)
    .select(SCHEMA.ACTOR.FIRST_NAME, SCHEMA.ACTOR.LAST_NAME)
    .from(SCHEMA.ACTOR)
    .fetch();

    Compatibility:

    Database products like SQLDialect.MYSQL and related dialects, such as SQLDialect.MARIADB use catalogs ("databases") instead of schemas, and lack schema support. For historic reasons, jOOQ treats MySQL catalogs as schemas and does not support any catalog qualifier in MySQL.

    Instances can be created using DSL.schema(Name) and overloads.
