Re: how use sql_slave_skip_counter to restore slave replication

Checking for all columns null
Is there a simple way of checking whether all the columns in a SELECT are NULL? I know I can do the following: SELECT c1, c2, c3 FROM t WHERE COALESCE(c1, c2, c3) IS NOT NULL but this relies on specifying every column I've selected (which in my actual code is a lot of columns that may change during development). I was hoping there was a convenience syntax for checking whether all the selected columns are NULL, without having to specify each column, e.g. in pseudocode SELECT c1, c2, c3 FROM t WHERE COALESCE(All_Selected_Columns) IS NOT NULL Is there such a thing?

Flushing the tables did not clear up the problem, so I have upgraded MySQL and will see how it goes. At http://dev.mysql.com/doc/refman/4.1/en/freebsd.html, I have also found the suggestion to set some kernel tunables in order to increase the maximum memory size of a process.

Re: load balance for mysql servers
Hello. >Is there any good idea to load balance for our mysql servers? I'm not sure, but have a look at "High Performance MySQL" by Jeremy D. Zawodny. This is a snip from it's publically available chapter. ### Real-time data transmission MySQL's replication isn't the ideal vehicle for transmitting real-time or nearly real- time data such as a stock quote feed or an online auction site. In those applications, it's important that the user sees up-to-date data no matter which database server they use. The only way to combat MySQL's lack of any latency guarantee is to implement your own monitoring system. It needs to use some sort of heartbeat to verify that each server has a reasonably up-to-date copy of the data. In the event that a server falls too far behind, the monitoring system needs to proactively remove it from the list of active servers until it can catch up. Of course, you can also build your application in such a way that it updates all the slaves with the newest data. However, that can add a lot of complexity and may not be worth the effort. You'd end up writing a lot of code to handle the exceptional conditions, such as when a single server falls behind or is intermittently inaccessible. Testing and debugging all those situations can be very time-consuming and difficult. As Derek went over this, he thought, "Wouldn't it be cool if MySQL could provide a query response that signified, `Go ask another server, I'm really busy right now'?" This would allow clients to automatically find willing servers in a multihost DNS rotation. For example, the client wants to connect to db.example.com (which is db1, db2, and db3). It connects (randomly) to db2, and the server answers the query with "I'm busy; go ask someone else," whereupon the client knows enough to try db1 or db3. Because the client library would be connecting to the same virtual server, it could transparently disconnect from the busy server and connect to some other (hopefully less busy) server. As a result, all you would need is some automated way for a slave server to know how far behind they are and to shut themselves off from queries when they get too far behind, and you'd have some protection. Of course, this could also be subject to a cascading failure. If all the slaves are very busy, the last thing you'd want is for them to start removing themselves from the pool of available servers. Continue on to Chapter 8 for a deeper discussion of these issues.

Re: ibdata1 File

Yes, this file contains important information. >Is this possible, or am I stuck having my database server off-line for >hours while the backup/restore procedure happens? You can setup a second server (or just run another instance of MySQL on the same machine), copy your databases there using mysqldump or replication, and switch to second copy. Its data could be a bit behind the main server, but you can quickly put it up to date. The general way, which I see is, to perform the dump with --master-data, get log file name and position in it from the dump file. Import the dump to the second instance. FLUSH TABLES WITH READ LOCK on the main server, get new updates which have appeared on the master, with mysqlbinlog utility (use --start-position=N option). Import them to the second copy and switch your applications to it. With replication this should be quite the same (FLUSH TABLES WITH READ LOCK on the master, get information from SHOW MASTER STATUS, use SELECT MASTER_POS_WAIT to put slave up to date). I agree, that this approach is not ideal, however it makes the time when you master is off-line to several minutes.

Re inconsistent replication?
Trying to help you with your replication problems is pretty much impossible without more information, such as: mysql versions and a more detailed explanation of your replication setup. I manage setups ranging from 1-14 replication slaves transmitting up to 2 gigabytes of data per day, and none of them have ever had problems that didn't come from user error. :) Atle - Flying Crocodile Inc, Unix Systems Administrator -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: load balance for mysql servers
Less optimal solution: Create a DNS round-robin alias, say mydatabase.myinternaldomain.com, that point to S2-4. "Optimal" solution: Set up a real load balancer, hardware based or software based (http://www.linuxvirtualserver.org/), and have it configured to distribute your connections. I have quoted optimal as your success depends on how you configure your distribution, but it should still work better than the previous solution.

Re: issue with subquery
Hi Dan, all! Dan Rossi wrote: Hi, im having some issues with a sub query in mysql5 , i have a field which is storing a static comma seperate list of primary keys ie 1,2,3,4 Call me pedantic, but I get suspicious: Is that a list of the four values "1", "2", "3", "4", or is it rather a single character string "1,2,3,4" ? Your text "static comma seperate list" makes me believe the latter. , i am then trying to use that to find entries in another table of the same primary keys here is the sql SELECT count(*) FROM feeds WHERE feedID IN (SELECT feeds FROM month_totals WHERE customerID=9 AND month_unique=1105) expected result should be 4 , i get 1. If i manually put in SELECT count(*) FROM feeds WHERE feedID IN (1,2,3,4) for instance i get 4 Here, SQL syntax clearly specifies that this is a list of 4 integer values. querying SELECT feeds FROM month_totals WHERE customerID=9 AND month_unique=1105 gives me 1,2,3,4 , what seems to be the problem ? Same question as above - a list of 4 values, or a single one? Show us your "create table" for the involved tables, and also sample data of "SELECT feedID FROM feeds".

Dan, I said I would help and I am offering to do so. If you would rather have someone else take over, please just say so and I will back off. This forum is the best place I have ever found for getting all kinds of crazy help and if you prefer someone else, I understand. I need some information about your table designs. Would you please post the SHOW CREATE TABLE statement results for the following tables: feed_usage, customers, feeds, producers_join, and month_totals? For example: SHOW CREATE TABLE feed_usage\G (the \G makes the output vertical, much less wrapping) I think I understand your various table relationships as you seem to set them up well in your example clause. FROM feed_usage fu INNER JOIN customers c ON fu.customerID=c.customerID INNER JOIN feeds f ON fu.feedID=f.feedID WHERE f.feedID IN (SELECT feedID FROM producers_join WHERE producerID IN (3)) AND fu.month!=DATE_FORMAT(NOW(),'%m%y') The funky numbers from your initial attempts will more than likely have been caused by several tables being joined having multiple rows of matching data. Not all data-based reports can exist as single statements. It's a limitation of the SQL language that when you want to do calculations based on the results of aggregation (SUM(), COUNT(), AVG(), etc.) , you need a second or more rounds of processing especially if you are aggregating several sets of data (usage data, bandwidth data, billing data, etc.). Temporary tables are the preferred place to store any intermediate results as they are specific to the connection that creates them (In fact the query engine generates at least one temporary table for every subquery you do). I don't want you to think I am completely against subqueries, I am not. It's just that you were not exactly using them to their full potential. If we keep our wits about us, we can get through this.

RE: set sql mode
An error is only thown during an INSERT or UPDATE statement, otherwise you just get a warning. - ERROR_FOR_DIVISION_BY_ZERO Produce an error in strict mode (otherwise a warning) when we encounter a division by zero (or MOD(X,0)) during an INSERT or UPDATE. If this mode is not given, MySQL instead returns NULL for divisions by zero. If used in INSERT IGNORE or UPDATE IGNORE, MySQL generates a warning for divisions by zero, but the result of the operation is NULL.

Thanks for your kind words of opinion, if you feel you have a better way please do go ahead , i am going to show you the sql i ended up using which was a union to append the current summary at the end, i then had to use php afterwards to add up the totals as i was getting unexpected results when grouping by month as it tended to play with the calculations. Most of the variables setup are for ease of reading because its such a huge query, i could have easily put the queries into the appropriate places, but i still for instance am required to send say the @customerID variable to the sub queries to return a sum of results, mind you it is not at all possible to do joins for any of this, i was needing to get certain values and caulcations i could not obtain from a sum, group, join of each row.
