Interface UCPConnectionBuilder

  • All Superinterfaces:
    java.sql.ConnectionBuilder
    public interface UCPConnectionBuilder
extends java.sql.ConnectionBuilder
    A builder created from a PoolDataSource object, used to get a connection to the database that the PoolDataSource object represents. The connection properties that were specified for the PoolDataSource are used as the default values by the UCPConnectionBuilder.

    To use the builder, the corresponding builder method needs to be called for each parameter that needs to be part of the connection request followed by a build() method. The order in which the builder methods are called is not important. However if the same builder attribute is applied more than once, only the most recent value will be considered while building the connection. The builder object can be reused to build more than one connection and the builder attributes will be retained across multiple invocations of the build() method.

    The following example illustrates the use of UCPConnectionBuilder to get a Connection: 

     
   PoolDataSource pds = new PoolDataSourceImpl();
   OracleShardingKey superShardingKey = pds.createShardingKeyBuilder()
                                           .subkey("EASTERN_REGION", JDBCType.VARCHAR)
                                           .build();
   OracleShardingKey shardingKey = pds.createShardingKeyBuilder()
                                      .subkey("PITTSBURGH_BRANCH", JDBCType.VARCHAR)
                                      .build();
                                
   Connection connection = pds.createConnectionBuilder()
                                    .user("rafa")
                                    .password("tennis")
                                    .shardingKey(shardingKey)
                                    .superShardingKey(superShardingKey)
                                    .build();
