Describes a database connection, which is required to initiate database operations.

Syntax

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.

index_schema = table_schema.createPrimaryIndex("primary");
index_schema.addColumn("num", IndexSchema.ASCENDING);

table_schema = conn.createTable("T2");
table_schema.createColumn("num", Domain.INTEGER);
table_schema.createColumn("quantity", Domain.INTEGER);

index_schema = table_schema.createPrimaryIndex("primary");
index_schema.addColumn("num", IndexSchema.ASCENDING);
index_schema = table_schema.createIndex("index1");
index_schema.addColumn("quantity", IndexSchema.ASCENDING);

conn.createPublication("PubA", new String[] {"T1"});
conn.schemaCreateComplete();

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.

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