  READS SQL DATA

EXAMPLES

Show next statement to be executed during a debugging session:

mysql> call rdebug_show_statement();
+----------------+--------------------+--------------+------------------------------------------------+
| routine_schema | routine_name       | statement_id | statement                                      |
+----------------+--------------------+--------------+------------------------------------------------+
| test           | analyze_continents |           98 | fetch continents_cursor into current_continent |
+----------------+--------------------+--------------+------------------------------------------------+
