public Connection

Remarks

A connection is obtained using the connect or createDatabase methods of the DatabaseManager class. Use the release method when the connection is no longer needed. When all connections for a database are released, the database is closed.

A connection provides the following capabilities:

The following example demonstrates how to create a schema for a simple database. The database contains a table named T1, which has a single integer primary key column named num, and a table named T2, which has an integer primary key column named num and an integer column named quantity. T2 has an addition index on quantity. A publication named PubA contains T1.

table_schema = conn.createTable("T1");
 table_schema.createColumn("num", Domain.INTEGER);
