Class ConnectionMetaData

java.lang.Object

com.link_intersystems.jdbc.ConnectionMetaData

All Implemented Interfaces:

TableReferenceMetaData

public class ConnectionMetaData
extends Object
implements TableReferenceMetaData

ConnectionMetaData provides convenient api to access the meta-data of a jdbc connection.

 Connection jdbcConnection = ...;
 ConnectionMetaData metaData = new ConnectionMetaData(jdbcConnection);

 ForeignKeyList foreignKeys = metaData.getImportedKeys("film_actor");

 ColumnMetaDataList filmActorColumns = metaData.getColumnMetaDataList("film_actor");
 ForeignKey foreignKey = foreignKeys.getByFkColumnDescription(filmActorColumns.getByName("actor_id"));
 assertNotNull(foreignKey);
 assertEquals("fk_film_actor_actor", foreignKey.getName());

 ColumnMetaDataList actorColumns = metaData.getColumnMetaDataList("actor");
 foreignKey = foreignKeys.getByPkColumnDescription(actorColumns.getByName("actor_id"));
 assertNotNull(foreignKey);
 assertEquals("fk_film_actor_actor", foreignKey.getName());
