Re: Long Running Queries
How do you do to benchmark a query ? I wish we had thought to have had him benchmark a query before and after he added an index. It would be interesting to see the difference in actual time that an index can make on a table with 450,000 records. On Wed, 2004-10-06 at 15:31, Jason Williard wrote: Amit, You are awesome!

Long Running Queries
Hello, I recently began experiencing issues that I would like some assistance with. Server Details: - Windows 2003 - MySQL Max 4.0.20a I have a table with 450,000+ records in it. When I try to run a single query, such as selecting 1 row or deleting 1 row using the WHERE clause, the query can take forever to run. In a specific case, it took 57 seconds to complete the SELECT query. Any ideas on how to speed this up? -- Thank You, Jason Williard -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Not without more information. At the very least, we need to see the query. Better yet, show us what EXPLAIN has to say about your query http://dev.mysql.com/doc/mysql/en/EXPLAIN.html.

RE: Long Running Queries
Sorry this is still new for me and I'm learning as I go. As I become more knowledgeable my questions will become more specific and detailed. Next question: If I have certain fields within tables that I will be querying often it is beneficial to set them as indexes for speedier lookups correct? If so, why is that? Thanks!

RE: Long Running Queries
Take a look at the docs for EXPLAIN (manual.html#IDX853). Use the 'possible_keys' column of the results to determine which column indexes will improve your query performance. Make sure your table has a primary key. Whenever possible, use the primary key in your WHERE clause when you SELECT or UPDATE a single row. You might get better results from this list if you include your table structure and your queries along with your question.

long running queries
Occasionally I have to add an index on a table with almost 2M rows and it takes a long time. This is expected but when adding the index it seems to block all other queries from other users from executing. Is there a way to prevent this?
