Interface Meta

All Superinterfaces:

Scope

public interface Meta
extends Scope

A wrapping object for DatabaseMetaData or for other sources of database meta information (e.g. InformationSchema)

This object can be obtained through DSLContext.meta() in order to provide convenient access to your database meta data. This abstraction has two purposes:

1. To increase API convenience, as no checked SQLException is thrown, only the unchecked DataAccessException
2. To increase API convenience, as the returned objects are always jOOQ objects, not JDBC ResultSet objects with hard-to-remember API constraints

This type is a Scope with independent lifecycle and its own Scope.data() map.

@Support
@NotNull List<Catalog> getCatalogs()
                            throws DataAccessException

Generate a migration script to get from this meta data to another one.

To some extent, some database migrations can be generated automatically by comparing two versions of a schema. This is what migrateTo() does. It supports:

• Schema additions / removals
• Table additions / removals
• Column additions / removals
• Column data type changes
• Constraint additions / removals
• Index additions / removals
• Sequence additions / removals
• Comment additions / removals

More complex, structural changes, such as moving some columns from one table to another, or turning a to-one relationship into a to-many relationship, as well as data migrations, can currently not be detected automatically.

Throws:

DataAccessException - If something went wrong fetching the meta objects

This allows for serialising schema meta information as XML using JAXB. See also Constants.XSD_META for details.
