How to optimize this SQL query?

In case you have your own slow SQL query, you can optimize it automatically here.

For the query above, the following recommendations will be helpful as part of the SQL tuning process.
You'll find 3 sections below:

  1. Description of the steps you can take to speed up the query.
  2. The optimal indexes for this query, which you can copy and create in your database.
  3. An automatically re-written query you can copy and execute in your database.
The optimization process and recommendations:
  1. Create Optimal Indexes (modified query below): The recommended indexes are an integral part of this optimization effort and should be created before testing the execution duration of the optimized query.
Optimal indexes for this query:
CREATE INDEX dba_exec_idx_task_name_parameter_name ON dba_advisor_exec_parameters (task_name,parameter_name);
The optimized query:
SELECT
        dba_advisor_exec_parameters.parameter_name,
        dba_advisor_exec_parameters.parameter_value 
    FROM
        dba_advisor_exec_parameters 
    WHERE
        dba_advisor_exec_parameters.task_name = '' 
        AND dba_advisor_exec_parameters.parameter_name = 'SQLSET_NAME'
