If you are using SQL Work Bench, you can try using Indexing, by adding an index to your tables, to add an index, click on the wrench(spanner) symbol on the table, it should open up the setup for the table, below, click on the index view, type an index name and set the type to index, In the index columns, select the primary column in your table.

Do the same step for other primary keys on other tables.
