executionResultSet:ResultSet

a result set as gotten from execution

Returns:ResultSet

a JDBC ResultSet

Exceptions
SQLException:

processInaccessibleDynamicResultback to summary
public boolean processInaccessibleDynamicResult(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

ResultSet to process.

Returns:boolean

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