Re: Dates: To Slash or to Hyphen. That is the question
if you don't want the user to input trash, don't give him the opportunity. on your form, put three two character input fields. label the fields month, day and year, or what ever is the most common order that your user will input a date. put '-' or whatever, between the fields - just to make them look pretty. now you get three fields back. each of which must contain a one or two digit number (don't worry about the year 2100 problem; neither you, your computer or your sfw will be here). checking for numbers is real easy. in fact, i would do the checking on the client side in javascript. yeah, you have to do a little more work in tearing apart and putting together dates and times. but this is a simple function. hth - obligatory strings mysql, database, sql At 03:18 AM 8/16/01 -0700, you wrote: On Thu 16.

Re: Float Issue
.1 can not be represented exactly on a binary machine. there must be an
approximation stored in the fractional bits of the floating point
representation. there are more fractional bits in a double than in a float.
so the approximation is better. see the user manual for exact sizes.

smaller numbers but when the values start getting big, this sort of thing
starts happening.

Re: Parsing text file into mysql database.
with the sircam virus going around, i'm not into opening attachments. my guess is that you are running into the cr/lf problem. windows terminates lines with a cr/lf. unix uses only a lf. so when you read the windows file, the cr terminates a record and then the lf terminates the interspersed empty record. hth At 08:42 PM 7/30/01 -0500, you wrote: While parsing into a mysql database using php, I have successfully entered data into the database from an uploaded txt file.

RE: Multiple users.
they can't access them! are you sure about that? indeed, if a user is logged on to the web host, he is acting in the environment imposed by the operating system on the user session. in this case, the other databases - given that the correct permissions are established - can not be accessed. but consider the case where the database is accessed thru a web page. Dubois briefly discusses this topic in MySQL. Now the user - any user - is running as whatever the web page server is running as. so if user A wants to provide web access to his database, the login name and password must be available to the user that the web page server runs as. so i can write a script, invoke it thru the web server and read user A's cnf file which gives me his login name and password. I just got access. I'm trying to figure out a solution to this problem. If anyone has a solution, i would really appreciate the answer. I have a solution to prevent modifying the database, but it is really ugly - full of security holes. i do not have a solution to prevent reading the database. my web host is running linux with an apache web server. thanks At 04:54 AM 7/7/01 -0600, you wrote: Why does it matter?

Re: Localization with MySQL
my only comment on this is that although you appear to have two different problems - you don't! pick a single solution to both cases; then when your solution needs modification, you only have one set of code to change. this obviously is computer science; only tenuously related to mysql. At 02:55 PM 7/7/01 -0600, you wrote: I'm working on two projects for which I'm trying to build in functionality to localize or internationalize later. For one project, a large chunk of text would be translated into an unknown number of languages. For this I'm allowing the text to be a 'text' field in a record, with other fields holding the language code (i.e. 'en', 'fr') and another the charset for that language. For the second, only a set of keywords would be translated into a small number of languages. For this project I'm using one record per keyword, with the various language translations being separate fields within the record - the record 'id' is what drives searches in this case. I'm using an Apache server with Perl and PHP, and MySQL as a db (of course). The only steps I'm taking is to have a field specifying the language (in the first case) and to name the columns/fields by the language code (i.e. 'en', 'de, 'jp') in the second. I'm also allowing twice as many characters for the 'jp' field, since that language requires (as I understand it) 'double' characters to drive it. I intend to drive the content by (1) selecting the language according to the 'Accept-Language' variable in the user's browser OR (2) allowing the user to select a language manually. Obviously I'm not up to speed on the exact requirements of localization and using other languages, and am concerned more about some pedestrian basics first - I'm just trying to avoid painting myself into a corner. Is there anything else I should be doing, or doing different? Can you point me to any resources on localization that would help me build this right the first time?

Re: re-sorting auto_increment fields
there is a way: delete the column add the column then the auto increment will start from 1 up to the number of records. be careful! if there are records in other tables which refer the records in this table - the one being modified - those records WILL NOT BE UPDATED. and now your database is really broken. you can postpone this problem for a very long time by using an unsigned bigint (0 - 2**64-1) note i said postpone, not eliminate. hth At 11:31 PM 7/7/01 +0100, you wrote: Hi ANy idea how i can get my auto_increment fields to renumber themselves after deletion of records so that they all get re-ordered and run consecutively from 1 to whatever without any numbers missing ?

Re: Searching records ?'s
indexing the entire large text column really drags performance down, and consumes big hunks of disk space. mysql has a good regexp facility. rtfm At 10:52 PM 7/6/01 -0700, you wrote: Hi Everyone, I'm writing a script using perl for a search function. I have a large text column that I want to scan for certain words. I do something like the following: select * from table_name where column_1 LIKE %word1% AND column_1 LIKE %word2%; In this situation, words like 'tree' will return 'streets'. How can I find exact matches while still scanning the entire record? Are there any MySQL REGEX's that might help out. I'm considering indexing the entire column and compare my query against it but wanted to see if there were any other solutions out there. Thanks!

Re: Good book for MySQL and Perl DBI?
Mysql by Paul Dubois, New Riders publisher, is strongly recommended. Get the perldoc on dbi and dbd. terse, but up to date. other reading are: cgi programming 101 by jacqueline hamilton. basic information. well presented. with examples that work. very broad, very shallow. of course the camel book, Programming perl, larry wall, tom christiansen and jon orwant, o'reilly, 3rd ed. with these books and the internet, you will find a wealth of information. ciao At 04:40 PM 6/23/01 -0500, you wrote: Does anyone have any recommendations for a good book on MySQL SQL?
