HP JDBC Type 4 driver DataBaseMetaData class.

Comprehensive information about the HP Neoview Database and Type 4 driver as a whole. This class lets applications

users know the capabilities of HP Neoview Database in combination with the Type 4 driver. Information returned by

methods in this class applies to the capabilities of a Type 4 driver and HP Neoview Database working together. A user

for this class is commonly a tool that needs to discover how to deal with the underlying HP Neoview Database. This is

especially true for applications that are intended to be used with more than one DBMS. For example, a tool might use

the method getTypeInfo to find out what data types can be used in a CREATE TABLE statement. Or a user might

call the method supportsCorrelatedSubqueries to see if it is possible to use a correlated subquery or

supportsBatchUpdates to see if it is possible to use batch updates. Some DatabaseMetaData methods return lists of

information in the form of ResultSet objects. Regular ResultSet methods, such as getString and getInt, can be used to

retrieve the data from these ResultSet objects. If a given form of metadata is not available, the ResultSet getter

methods throw an SQLException. Some DatabaseMetaData methods take arguments that are String patterns. These

arguments all have names such as fooPattern. Within a pattern String, "%" means match any substring of 0 or more

characters, and "_" means match any one character. Only metadata entries matching the search pattern are returned. If

a search pattern argument is set to null, that argument's criterion will be dropped from the search. A method that gets

information about a feature that the Type 4 driver does not support will throw an SQLException. In the case of

methods that return a ResultSet object, either a ResultSet object (which might be empty) is returned, or an

SQLException is thrown.
