multiple PRI indexes
is it generally recommended / a good idea to have more than one PRI index in the same table? i've never seen that before until today while trying to track down bugs in someone else's system and noticed a table with 2 PRI indexes. will this cause any problems? tia. ~shawn - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Re: Query
try using "SHOW FIELDS FROM TABLE LIKE EXPR", where 'TABLE' is the name of the name of the table, and 'EXPR' is an expression indicating what you wish to match. for example, to get the information about a column called 'ckey' in table 'config', you would do: "SHOW FIELDS FROM CONFIG LIKE 'CKEY'". hope this helps. ~shawn On Mon, 13 Aug 2001, Matthew Marcus wrote: > > Hello, > > Having trawled through the documentation for a while I'm none the wiser - > is there any way of retrieving the data type of a single column using > MySQL?

Re: New member question
there are a number of ways you could accomplish this. depending on how large the database is, you may want to try exporting it to csv (comma separated value) format, and then importing it into mysql, using either the "load" command, or a third-party utility like phpmyadmin (which is what i generally use for tasks like that). another way is if you are indeed using php and you have odbc support compiled in... you could simply read from the access database and simultaneously write it to a new mysql table. that's what i could think of offhand..someone else out there might have a better solution or three. =) ~shawn On Sat, 4 Aug 2001, RCA Webmaster wrote: > > I have just subscribed to this list, so forgive me if my question has been > answered many times before but I was not sure where else to find this > information. > > I am new to mysql and am going to be using it on a website that I maintain. > My question is, is there a program/utility or easy way to convert an MS > Access database to mysql format? > > Thanks, > > Chris > > > > --- > Outgoing mail is certified Virus Free. > Checked by AVG anti-virus system (http://www.grisoft.com). > Version: 6.0.265 / Virus Database: 137 - Release Date: 7/18/01 > > > - > Before posting, please check: >http://www.mysql.com/manual.php (the manual) >http://lists.mysql.com/ (the list archive) > > To request this thread, e-mail <[EMAIL PROTECTED]> > To unsubscribe, e-mail ><[EMAIL PROTECTED]> > Trouble unsubscribing?

Re: Select
just out of curiousity, was there a particular advantage to you using varchar as opposed to date for the column type? because if so it would be a lot easier to manipulate that date.. you could calculate differences in dates, get portions of the date, and all sorts of other nice things if it were a date column... ~shawn On Thu, 2 Aug 2001, Augusto Cesar Castoldi wrote: > HelpHi. > > I have a colun in my table for the birthday.: "DD/MM/".

Re: Linking a Form
mark,
you need to actually write the code somehow in frontpage. i've not dealt
w/ frontpage in a LONG time (mainly cos i can't stand it, but that's
personal opinion so i'll refrain from commenting) ... but i believe there
is a way you can write raw html or php code in there somewhere. that part
you'll have to figure out on your own. :)
the actual php code you'll need really isn't that difficult, something
like this usually works for me:
$link = mysql_connect("hostname.com", "username, "password");
$query = "select * from table where field='blah'";
$result = mysql_db_query("database", $query, $link);
while($row = mysql_fetch_assoc($result)) {
print "The value of 'address' is: " . $row["address"];
}
mysql_close($link);
that's just a rough example, but basically what it does, is: connect to
the database; execute a query, storing the result of the query in the
$result variable; create an array called $row containing the contents of
the query; and loop through that array record by record, printing the
value of the "address" field.
i hope that example was clear enough, i'm not the best at explaining
things sometimes. if you need more information on mysql and php, you can
find it at the following url:
http://www.php.net/manual/en/ref.mysql.php
hope this helps!

Re: reindexing tables
i've tried simply re-creating the index as you suggested ... no luck. here's a brief summary of my situation: i developed an application on one server, after it was developed and ready to go live we started to move it to another server. after moving it i noticed my search function wasn't working... i fiddled around with the database quite a bit, with no luck. then i realized that the search function wasn't working on the development server either, and it had been working fine all along. that's what makes no sense to me at all. :( output from myisamchk on the development server is as follows: *** Checking MyISAM file: inventory Data records: 2 Deleted blocks: 5 myisamchk: warning: 1 clients is using or hasn't closed the table properly - check file-size - check key delete-chain - check record delete-chain - check index reference - check data record references index: 1 - check data record references index: 2 - check data record references index: 3 - check data record references index: 4 - check data record references index: 5 - check data record references index: 6 - check data record references index: 7 - check data record references index: 8 - check data record references index: 9 - check data record references index: 10 - check data record references index: 11 - check data record references index: 12 - check record links MyISAM-table 'inventory' is usable but should be fixed *** i'm not real familiar with myisamchk so i'm not sure exactly what i need to do to repair this table, since it said it should be fixed. i also still have no clue why this search suddenly stopped working. =/ frustrated, ~shawn On Mon, 30 Jul 2001, Werner Stuerenburg wrote: > What about issueing first drop index, then add index?

reindexing tables
hi all, i apologize for the utterly newbie-ish question, but i've yet to find an answer to it after having spent quite some time searching mysql's web site (especially since half the links i click on now seem to be giving me 404 errors...) how does one reindex a table containing fulltext indexes? the reason i ask this is... a table that i had set up w/ fulltext indexes suddenly returns no rows when i perform a search on it... and it used to work just fine. everything i have read seems to be telling me to reindex the table.. and quite frankly that's the only thing i can think of doing since nothing else has changed that should be causing the searches to no longer function properly. any help would be appreciated. ~shawn - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
