RE: newbie question on scrolling through a table one record at a time
Many thanks for your reply Tom. I will read it more closely over the week-end, but wanted to say thanks straight away. Kerry -Original Message- From: Tom Horstmann [mailto:[EMAIL PROTECTED] Sent: 20 August 2004 15:52 To: 'Kerry Frater'; 'MySQL List' Subject: RE: newbie question on scrolling through a table one record at a time Hi Kerry, The problem is more fundamental with the scrolling through the records/rows of Master. [..] It is not sensible to allow 200 million pieces of data to be transferred to the Delphi PC to build a local Dataset to scroll through. [..] Getting the first row is easy select * from Master order by MasterRef limit 1; It is, but LIMIT mostly is executed after getting all records meeting the WHERE-condition. That might be quite slow. but getting the next record isn't as straight forward. Mainly because I have no idea of what the next value of MasterRef is. All I know is that I want to get the next row in sequence. None of the papers I have or have seen addresses this issue. Either this concept is not required in SQL programming or it is so obvious that it doesn't need explaining. Either way I can't see the wood for the trees. If MasterRef is a unique value column then the next record would be: select * from Master order by MasterRef limit 1 where MasterRef MyCurrentMasterRefValue; This simply raises questions 1) how to get the previous row (presume you use the DESCENDING keyword of the table, 2) how to test for Begining and End of Table and 3) what to do if the column being ordered on is not unique. I ran through the same problem the last days (still). This is how i did it: At first you need a unique key (auto-increment). I name it id. If you have records that are non-unique by the column you want to sort them, try to add other columns to sort on to get them as unique as you can. Having non-unique records isn't a problem as long there are not many beeing equal. How to move through records: Starting with a value of '', always SELECT the record having a higher value in that columns you sorted on than the last one. As you said, that's all, if there all records are unique. You will need LIMIT to get through equal records. It's quite easy having an example: record key 1a 2a 3b 4b 5c Get the first record (assuming your id starts with 0): SELECT key FROM table WHERE key='' AND id-1 ORDER BY key,id LIMIT 0,1 Store these: old_key = key old_id = id Get the next record: old_key = SELECT key FROM table WHERE key=old_key AND idold_id ORDER BY key,id LIMIT 1,1 The LIMIT has to be 1 here to get the second record. As long as key stays equal to old_key, increase the limit by one for each record fetched. When getting a new value for key, set the limit to 1 again. You need to find a good relation between the amount of equal records and the columns you use to sort and move on. 500 records having the same key will make things slow, but using a long WHERE- clause will do, too. I tested this for upto 3 records. If there is an index on all columns used in the SELECTs, speed seems to be stable upto that size. hth, TomH -- PROSOFT EDV-Loesungen GmbH Co.

Help with --with-debug
Hello This is probably real simple for someone that knows - I'm having a few problems installing MySQL on a particular server (it's repairing a damaged copy). I'd like to try and fix it myself so I'm recompiling with the --with-debug option. If I manage to fix the problem, is there any overhead of having MySQL built with --with-debug? Or should I eventually recompile without --with-debug when the server is put into production?

Help: Retrieving time stamp
Is there something wrong with this code ?
Still confused after reading the manual.
td?php echo
$rsJobShortDat-Fields('DATE_FORMAT('LFWJobBank'.'Entered','%m/%d/%Y'));
?/td
Entered is a timestamp column.
With the apostrophes off the table / column I get
errors about unexpected % .
Here is my SQL statement
SELECT
LFWJobBank.JobReferenceCode,DATE_FORMAT(LFWJobBank.Entered,'%m/%d/%Y'),
LFWJobBank.DazeLeft, LFWJobBank.JobTitle
FROM LFWJobBank
WHERE VendorID = colname

Re: Help: Retrieving time stamp
Stuart, why not change your select statement (assuming it is correct and
actually works, in and of itself) to give the date-formatted field an
alias:
SELECT
LFWJobBank.JobReferenceCode,DATE_FORMAT(LFWJobBank.Entered,'%m/%d/%Y') AS
date_entered,
LFWJobBank.DazeLeft, LFWJobBank.JobTitle
FROM LFWJobBank
WHERE VendorID = colname
Then your php code should change to grab 'date_entered' (probably without
having to format it once again). I don't use PHP that often, so I'm not
sure of the right syntax myself - let someone else comment on that!
But I do remember it is useful in testing to have php output the full
SQL query text to the browser, just so you can see it is correct before
proceeding.
Cheers
Terry

After 2 days in Microsoft HELL with my SQLsvr databases, I'm ready to rob the piggy bank and build a new linux mysql server. Here's my problem: I have, at present, two rather large databases.

Re: A new Machine
I have to agree with Chis on the single cpu box. We have been building our own boxes using AMD Athlon 64 3400+. Make sure you get the chip with 1mb cache. The hyperchannel on these make IO so much faster. A couple of fast SATA drives in a raid config and you are ready to go. There is a new ASUS MB out that supports dual channel ddr memory for the Athlon 64. Should be really good. Just my 2 cents worth.

I posted a message on their forum, but they deleted it and sent me a really snotty message. So I paid the extra money for Navicat and have no regrets. I'm now more comfortable working with phpMyAdmin, but I still prefer Navicat for importing data. I read a review that raved about Navicat's log feature. I think they were referring to the logs that are created when you import data. If there are errors in your data, the logs help you track them down. I don't know if Navicat is the only software with this feature, but it is a tremendous help. I just recently learned about two new programs on another list.
