Hi, Can anyone help and offer some advice with regards MySQL indexes. Basically we have a number of different tables all of which have the obviously primary keys. We then have some queries using JOIN statements that run slowly than we wanted. How many indexes are recommended per table ? For example should I have a index on all fields that will be used in a WHERE statement ? Should the indexes be created with multiple fields ? A example of two basic queries
SELECT auto_id, name, score FROM test_table WHERE score > 10 ORDER BY score DESC SELECT auto_id, name, score FROM test_table WHERE score > 10 AND name Like '%Red%' ORDER BY score DESC How many indexes should be created for these two queries ? Thanks, Neil
