questions mean what?
does the questions counter equate to the number of queries ran against the database? or then number of questions a query may have to ask the database for one query? if I do a select * from table1; and table one has 100 records does that equate to 100 questions or one question?

what does show status 'questions' refer to?
in the show status there is a line that says Questions and it shows a number The manual says this is the number of questions asked the mysql database. what I want to know does one query equal one question or if I did the select * and it brought back 100 rows... does that equate to 100 questions? Trying to get number of hits to the database. Maybe there is a better way to get that.

RE: what does show status 'questions' refer to?
Thanks guys... I think questions does it. I just want to know how many queries hit the database. I am getting ready to unleash our company phonebook, with 10,000 plus listings and just want to make sure that it can handle it. I have a jndi connection pool established and have the max used connections set to 200. We are in testing mode and we set around 24 max used connections all the time. Is the the current number of users on the database when I did a show status or is that the top number of users on the database at any given time? Like a max indicator since the database was up. What value should I change the default 28800 wait timeout to for connections? Do these two values relate? Max Used Connections and Wait Timeout?

I see Paul DuBois has already answered that; he's on the Documentation Team at MySQL so he's a pretty authoritative source. Trying to get number of hits to the database. Maybe there is a better way to get that. I've never seen a database that automatically tracks the number of hits to the database. That doesn't mean that MySQL doesn't do it - maybe someone here can answer that with 100% certainty - but I'd be a little surprised if it did. I'm wondering what hits means in the original question. If it refers to statements executed, the Questions value may be sufficient. If it refers to rows returned by statements, I don't believe there is a way to get that value. You can count the results from your own statements, of course, but if you connect a bunch of times all at once, each connection can count only its own statement results. And you cannot count the results from queries issued by clients that connect using other accounts. If you're interested in statements executed, broken down by statement type, try this: SHOW STATUS LIKE 'Com%'; However, the Com_select value reflects only SELECT statements actually executed by the server. If the query cache is on, some SELECT statements may be served directly out of the query cache without the server having to execute them. You can get the number of such queries like this: SHOW STATUS LIKE 'Qcache_hits'; -- Paul DuBois, MySQL Documentation Team Madison, Wisconsin, USA MySQL AB, www.mysql.com MySQL Users Conference: April 14-16, 2004 http://www.mysql.com/uc2004/ EMAIL CONFIDENTIALITY NOTICE This Email message, and any attachments, may contain confidential patient health information that is legally protected.

max used connections question
Does this number indicate the current number of connections or the max number of connections during the current uptime? We have this number max set to 200 from the default 100 how does this number go down during uptime? It hovers around 30 - 40 but sometimes goes to 90 But it does not seem to go back down without restarting the mysql service Dean-O EMAIL CONFIDENTIALITY NOTICE This Email message, and any attachments, may contain confidential patient health information that is legally protected.

Table says it is read only but it is not from file system level
I am running an sql insert against a mysql table version 3.23.52 When from the file system level the table has the following permissions. rw-rw-r-- table.frm rw-rw-r-- table.MYD rw-rw-r-- table.MYI When the sql runs it says the table is read only. I am connecting to the table as root and I have set the password too. I am using java to do this sql operation. I can select items from the table, but can not insert them.
