All Known Implementing Classes:: JDBCDatabaseMetaData

public interface DatabaseMetaData
extends Wrapper

An interface which provides comprehensive information about the database management system and its supported features.

This interface is implemented by JDBC driver vendors in order to provide information about the underlying database capabilities in association with the JDBC driver.

Some of the methods in this interface take string parameters which are patterns. Within these string patterns, '%' and '_' characters have special meanings. '%' means "match any substring of 0 or more characters". '_' means "match any character". Only metadata entries that match the pattern are returned. If such a search pattern string is set to null, that argument's criteria are dropped from the search.

The subset is determined by restricting to those attributes whose name matches the attributeNamePattern and whose type name matches the typeNamePattern. Each row of the ResultSet describes one attribute, and the rows are ordered by the columns TYPE_SCHEM, TYPE_NAME and ORDINAL_POSITION. Inherited attributes are not included.
