Accessing Database Metadata

To JDBC support DatabaseMetaData methods, Sybase provides a set of stored procedures that jConnect can call for metadata about a database.

These stored procedures must be installed on the server for the JDBC metadata methods to work.

If the stored procedures for providing metadata are not already installed in a Sybase server, you can install them using stored procedure scripts provided with jConnect:

sql_server.sql installs stored procedures on Adaptive Server databases earlier than version 12.0.
sql_server12.sql installs stored procedures on Adaptive Server database version 12.0.x.
sql_server12.5.sql installs stored procedures on Adaptive Server database version 12.5.x.
sql_server15.0.sql installs stored procedures for Adaptive Server 15.0 through 15.5.
sql_server15.7.sql installs stored procedures for Adaptive Server 15.7 or 15.7 ESD # 2.
sql_server15.7.0.2.sql installs stored procedures for Adaptive Server 15.7 ESD #2 or later.
sql_asa.sql – installs stored procedures on the SQL Anywhere database version 9.x.
sql_asa10.sql – installs stored procedures on the SQL Anywhere database version 10.x.
sql_asa11.sql – installs stored procedures on the SQL Anywhere database version 11.x.
sql_asa12.sql – installs stored procedures on the SQL Anywhere database version 12.x.

Note: The most recent versions of these scripts are compatible with all versions of jConnect.

See the Sybase jConnect for JDBC Installation Guide and Sybase jConnect for JDBC Release Bulletin for complete instructions on installing stored procedures.

In addition, to use the metadata methods, you must set the USE_METADATA connection property to true (its default value) when you establish a connection.

You cannot get metadata of temporary tables in a database.

Note: The DatabaseMetaData.getPrimaryKeys method finds primary keys declared in a table definition (CREATE TABLE) or with alter table (ALTER TABLE ADD CONSTRAINT). It does not find keys that are defined using sp_primarykey.
