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
.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.

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
There are secure telnet packages. one for windows is SecureCRT. see
www.vandyke.com
for tips and pointers: basic telnet gives you a link to your server thru
your own pc. it is as if you were directly connected to your server.

yes, but then you wouldn't learn. if you don't want to buy Dubois' book,
try appendix J of the mySql reference manual, available for free from the

Mark:
the key to this puzzle is the separator, the ';'
for your first question, you need to find the ';' followed by a 6. not just
any ';', but the first ';'
the pattern would be ^[0-9]*;6
which says
^ find beginning of line
[0-9]* followed by zero or more instances

but before you issue this command and possibly trash your database, use
select * from a_table where status='flag_value';
to look at the records which will be deleted. you may find some surprises.

indeed, if a user is logged on to the web host, he is acting in the

case, the other databases - given that the correct permissions are

actually you are already using mysql.
what you need to do is specify a database to use.
to see the available databases, type
show databases;
then type
use db name

if none of the existing databases are appropriate you must create a

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.

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.
