Re: Wait for data to change
Shawn, I like your idea very much. Unfortunately I am not using version 5 yet, but this may hasten my upgrade. My initial thought was to try and find a function like PostgreSQL's LISTEN command (http://www.postgresql.org/docs/8.0/interactive/sql-listen.html). But I think this method is better. As an extension to your idea, my UDF function can broadcast messages using the RSS protocol. I am sure there are some easy to use libs out there. My listening thread(s) can feed off the RSS listening for trigger events. This negates the use of a polling thread, and indeed the entire thread. I don't need a connection to the database at all until I know there is data there. Magic :) Thanks, Ben.

I believe there is an alternate method where a thread can be made to wait for some change, therefore avoiding the expensive polling and improving performance. If any member knows what this may be, I would be very interested. Regards, Ben Clewett. I can't think of any way to do this efficiently without a trigger, a UDF, and a custom daemon. I assume based on your description that you have some sort of client application that needs to know if some data value has changed. However, you don't want to keep pinging the server to continuously ask has it changed yet, has it changed yet, has it changed yet... Here's how I think you can make this work with some sort of efficiency. You need to setup your application to connect to a daemon on some server somewhere. The only purpose of this daemon is to broadcast to those clients who connect to it a message to the effect that some data has changed on the table you are interested in. If you wanted to get really fancy, the message could say what data changed and possibly what the new value is. That way your client could possibly act on the data without needing to poll the server. How does the daemon know that data just changed? That's where the trigger and UDF come in. Triggers are fired during certain database events (adding records, changing records, or deleting records). I don't know for certain but I believe triggers can use UDFs in their code. The UDF that is called by the trigger detecting a change in the table you are interested in is what notifies the daemon (described earlier) that the data has changed. And, because the UDF is only called from within a trigger, you only bother the daemon when a change actually occurs. The downside to this design is that triggers are not supported until 5.x (still in testing) so I don't know if you have that option. User-defined functions (UDFs) may be able to cover the job by themselves IF and only if you can control data changes to ALWAYS use your UDF. Otherwise some changes may slip through the cracks. Anyway, that was my idea. Is there any other way for you to communicate a change in data than a passive detect like you are doing? How much control do you have over what can and cannot change your data (specifically the field you keep polling)? What other application-based options are open to you?

Getting error 136 during an update
Hello there, I am receiving Got error 136 from storage engine and I need some light on this matter. I have a table with 23,000,000 records and I want to update it with datas from another one with the exact same amount of rows. The 2 tables can be linked by a primary key. Both tables are myISAM, and have not other key than the primary one. The server is a test server, on WinXP Pro. I run an UPDATE, like this one : UPDATE tbl1 INNER JOIN tbl2 USING (PKEY) SET tbl1.NUM = tbl2.COL1, tbl1.ADRESSE = tbl2.COL2, tbl1.CITY = tbl2.COL3; It actually updates 6 collumns but the problem does not seem to be here. When I run this query, it runs for a bit and then I got : Got error 136 from storage engine At first, I thought it would be the filesize limit of 2GB, but this file size is not valid because I have a NTFS file system. So I tried an update like that, just after my error : UPDATE tbl1 INNER JOIN tbl2 USING (PKEY) SET tbl1.NUM = tbl2.COL1, tbl1.ADRESSE = tbl2.COL2, tbl1.CITY = tbl2.COL3 WHERE tbl1.PKEY 2200; And it worked fine ! And the next one too : UPDATE tbl1 INNER JOIN tbl2 USING (PKEY) SET tbl1.NUM = tbl2.COL1, tbl1.ADRESSE = tbl2.COL2, tbl1.CITY = tbl2.COL3 WHERE tbl1.PKEY 1800 and tbl1.PKEY = 2200; So I am wondering where the problem comes from.

SELECT rows from the previous business day
A table exists with id and datetime columns; I need to SELECT records from the previous business day. I began with this: SELECT id FROM table WHERE TO_DAYS(NOW()) - TO_DAYS(datetime) =1 But if NOW() is a Monday, it pulls records from Sunday (there are none since records are inserted M-F only).I thought of using something like this in my WHERE clause: AND DAYOFWEEK(datetime) != 6 Though this doesn't seem like an operable solution (If I'm not mistaken this would return 0 rows if no records were inserted on a Sunday).

Re: Data Standards on Database Export-Import
Z X C V [EMAIL PROTECTED] wrote on 03/21/2005 08:32:24 PM: Hello, Are there any good rfcs or other documents that would assist in the discussion I'm having with our organization's Oracle programmers in regards the following: Oracle DB - MySQL They recommend: ~ col~col ~col~ col',~col NOTE::I placed the ' in for a reason. I am looking for: col,col,col,col\'\,,col Of course the non-Oracle system is being tasked as the problem in this case for the abnormal data request. Any help on this would be appreciated. Rob. Unfortunately I am not sure any document like you seek actually exists (at least not in any modern literature). There are many ways to move data from memory to media and the format of the data on the media is usually determined by a number of factors (type of data, type of media, is the data intended for human or machine use, etc.). So I am not sure there ARE any standards for database export formatting (I did a quick Google and didn't find any in the top 50 responses for the search: data export standard format CSV (see notes below))... To be honest, the mysqlimport and LOAD DATA INFILE facilities should be flexible enough to read the tilde-delimited format that your Oracle guys want to give you. If not, you should be able to ask them to either create a tab-delimited or comma-delimited dump (both formats are so ancient as to be /de facto/ standards and should be something that Oracle can create without any difficulty). What you were asking for is a comma-delimited format but you need some extra escaping to make it more MySQL compatible. I think that the extra escaping is what's throwing a monkey-wrench into the export process. One viable option is for you to write a quick converter that re-parses their tilde-delimited format into something properly escaped for MySQL. IF you write it correctly, your format converter should be able to process several megabytes of dumped data per second. Yes, it's a pain in the neck to take the extra conversion step but sometimes we DBA's have to assemble our own lemons before we get to make the lemonade.

Re: SELECT rows from the previous business day
A quick try: In most cases you need results from yesterday, but for Sunday and Monday we must correct extra for the weekend. DAYOFWEEK() returns 1 for Sunday, 2 for Monday, etc., so we can use this to make a correction value: SET @COR = (DAYOFWEEK(NOW()) 3) * DAYOFWEEK(NOW()); SELECT * FROM table WHERE `datetime` CURDATE() - INTERVAL (1 + @COR) DAY AND `datetime` CURDATE() - INTERVAL @COR DAY; This construction is index-friendly, because MySQL will reduce the calculation to a constant before running the query. The result is a simple col constant expression which can make use of indexes if they are present. Expressions such as TO_DAYS(`datetime`) (as suggested by you) will result in a full table scan and slow down the query significantly. If you consider Saturday as a business day you only need to make a correction for Monday: SET @COR = (DAYOFWEEK(NOW()) = 2); Regards, Jigal. - Original Message - From: Stembridge, Michael [EMAIL PROTECTED] To: mysql@lists.mysql.com Sent: Tuesday, March 22, 2005 4:30 PM Subject: SELECT rows from the previous business day A table exists with id and datetime columns; I need to SELECT records from the previous business day.

SET @TodaysDate = CURDATE(); SET @LastBusDayStart = IF(DAYOFWEEK(@TodaysDate)=1 , @TodaysDate - INTERVAL 2 DAY , IF(DAYOFWEEK(@TodaysDate)=2 , @TodaysDate - INTERVAL 3 DAY , @TodaysDate - INTERVAL 1 DAY ) ); SET @LastBusDayEnd = @TodaysDate + INTERVAL 1 DAY; Then your new, very fast (because you can use an index) query looks like: SELECT id FROM table WHERE datetime_field = @LastBusDayStart and datetime_field @LastBusDayEnd; The 40 or 50 milliseconds it takes to compute the starting and ending dates in the SET clauses saves you insert huge quantity noun here of time because you move the calculation OUT of your query. The query only needs to evaluate against constant values and will not need to compute a date difference for each row as it would have had to do using your original query.

RE: remote connection problem
When you are running as root, but are you running as 'root'@'%' or 'root'@'localhost'? This does make a big difference. The '%' means all network connections, which isn't secure. I would only using it as testing purposes. However, because your error message says that you cannot see the server, are you sure that your remote connection can see the NT server? This may be a bigger problem, i.e. DNS or IP routing/access lists. You may also want to check the hostname.err logs on the MySQL server to see if there is a connection problem there.

One other thing to check, make sure --skip-networking isn't specified in your configuration. mysql show variables like 'skip_networking'; +-+---+ | Variable_name | Value | +-+---+ | skip_networking | OFF | +-+---+ 1 row in set (0.00 sec) If the value is ON, you won't be allowed to make connections to the server via TCP/IP.

Re: remote connection problem
Not necessary to change my.cnf, unless --skip-networking was specified. Also assuming that you are using port 3306. mysql show variables like 'port'; +---+---+ | Variable_name | Value | +---+---+ | port | 3306 | +---+---+ 1 row in set (0.00 sec) Can you verify that network traffic is getting from your remote client to the MySQL server? When you attempt to connect, do you see network packets coming to port 3306 on the MySQL server machine?

Re: Passing Arrays between pages
Or you can issue session_start() at the top of each page, assign your array to $_SESSION[] in one page, and pluck it from the session array in the other page.

I have tried something like this and have tried many variations of this but nothing working yet ; Page 1 $testArray[0] =Apple; $testArray[1] =Banana; $testArray[2] =Peach; echo "INPUT NAME = \"kcompany[]\" TYPE = \"hidden\" VALUE=\"$testArray\""; Page2 echo $testArray[1]; This is more of a PHP question, and I'm sure you'll be admonished for it, but I'll answer it anyway. Essentially, you need to construct the array elements as their own hidden values. echo "INPUT NAME = \"kcompany[]\" TYPE = \"hidden\" VALUE=\"Apple\""; echo "INPUT NAME = \"kcompany[]\" TYPE = \"hidden\" VALUE=\"Banana\""; echo "INPUT NAME = \"kcompany[]\" TYPE = \"hidden\" VALUE=\"Peach\""; At that point, if you call: echo $kcompany[1]; after the form submit, you'll get Banana.
