Method Detail

getNestedConnection

java.sql.Connection getNestedConnection(boolean internal)
                                 throws java.sql.SQLException

Get a new connection object equivalent to the call

                DriverManager.getConnection("jdbc:default:connection");
                

Throws:

java.sql.SQLException - Parent connection has been closed.

getResultSet

java.sql.ResultSet getResultSet(ResultSet executionResultSet)
                         throws java.sql.SQLException

Get a jdbc ResultSet based on the execution ResultSet.

Parameters:

executionResultSet - a result set as gotten from execution

Throws:

java.sql.SQLException - on error

processInaccessibleDynamicResult

boolean processInaccessibleDynamicResult(java.sql.ResultSet resultSet)

Process the resultSet as a dynamic result for closure. The result set will have been created in a Java procedure. If the ResultSet is a valid dynamic ResultSet for this connection, then it is set up as a dynamic result which includes:

• breaking its link with the JDBC connection that created it, since there is a good chance that connection was closed explicitly by the Java procedure.
• marking its activation as single use to ensure the close of the ResultSet will close the activation.

If the result set a valid dynamic result then false will be returned and no action made against it.

Parameters:

resultSet - ResultSet to process.

Returns:

True if this ResultSet was created by this connection and the result set is open. False otherwise.
