Database Programming with JDBC & Java, Second Edition

Name

DatabaseMetaData

Synopsis

Interface Name: java.sql.DatabaseMetaData

Superclass: None

Immediate Subclasses: None

Interfaces Implemented: None

Availability: JDK 1.1

Description

This class provides a lot of information about the database to which a Connection object is connected. In many cases, it returns this information in the form of JDBC ResultSet objects. DatabaseMetaData will throw a SQLException for databases that do not support a particular kind of meta-data.

DatabaseMetaData methods take string patterns as arguments in which specific tokens within the String are interpreted to have a certain meaning. % matches any substring of or more characters, and _ matches any one character. You can pass null to methods in place of string pattern arguments; this means that the argument’s criteria should be dropped from the search.
