executeAsync

public ResultSet executeAsync(String sql)
                       throws SQLException

Description copied from interface: IDatabricksStatement

Executes the given SQL command asynchronously and returns a lightweight result set handle. This method initiates the execution but does not wait for it to complete, making it suitable for long-running queries. The actual results can be retrieved later using IDatabricksStatement.getExecutionResult().

Specified by:

executeAsync in interface IDatabricksStatement

Parameters:

sql - The SQL command to be executed

Returns:

A ResultSet handle that can be used to track and retrieve the results

Throws:

SQLException - if a database access error occurs, this method is called on a closed statement, or the SQL command is not valid

getExecutionResult

public ResultSet getExecutionResult()
                             throws SQLException

Description copied from interface: IDatabricksStatement

Retrieves the result set for a previously executed statement. This method should be called after executing a statement using IDatabricksStatement.executeAsync(String) to get the actual results.

Specified by:

getExecutionResult in interface IDatabricksStatement

Returns:

A ResultSet containing the results of the statement execution in case of successful completion, else handle for the result status.

Throws:

SQLException - if the statement was never executed, has been closed, or if a database access error occurs
