Examples of DatabaseMetaData

java.sql.DatabaseMetaData
An interface which provides comprehensive information about the database.
This interface is implemented by JDBC driver writers in order to provide information about the underlying Database capabilities and the JDBC driver capabilities taken together.
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 one 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.
