FW: how to create database (auto)
Hi Richard, Do you think the following links may help? I got them from the online manual: [1] http://www.mysql.com/doc/en/CREATE_DATABASE.html [2] http://www.mysql.com/doc/en/CREATE_TABLE.html [3] http://www.mysql.com/doc/en/CREATE_FUNCTION.html [4] http://www.mysql.com/doc/en/CREATE_INDEX.html [5] http://www.mysql.com/doc/en/Cannot_create.html [6] http://www.mysql.com/doc/en/SHOW_CREATE_TABLE.html This was an automated reply to your message about 'how to create database'. I used 'create database' as a keyword to query the database. If you no longer want to receive messages from the bot, send email to [EMAIL PROTECTED] with subject unsubscribe. P.S.

RE: Row numbers
: Is there a way to get a row number returned with any select query? Row number is not available for some queries (ex.DELETE FROM table_name) for efficiency. You can disable it with a dummy WHERE clause: DELETE FROM table_name WHERE 1 0; It will be slower, but you'll get the desired result - 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: Row numbers (I thought of a new feature)
I thought of a new feature... XSLT's position()-like functionality in the new releases of MySQL. position(), in XSLT, returns position of the node in the document tree. In MySQL it would return position of the record in the returned result set (from SELECT query): Example: SELECT POSITION(), first_name, last_name WHERE last_name LIKE a%; Return value might be: 1 | Alpha | Beta | 2 | Aqua | Gamma | ... etc.. By default numbering would start with 1. But it can be alterled by passing argument to POSITION(). I believe it is an exciting feature. sherzod - 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: Generating an automatic e-mail via MySQL
: Does any one have a suggestion on running a daily / weekly e-mail : notification based on results from a MySQL query? In your cron file do something like: echo select * from table | mysql [options] db | mail [EMAIL PROTECTED] If it's a more complex query: cat ~/query.sql | mysql [options] db | mail [EMAIL PROTECTED] It still doesn't solve your problem perfectly, since you can't set email addresses dynamicly in that manner.

This also requires a little more complex SQL query to retrive them. I would probably use some minimum markup to mark the sections, and store the whole policy in a single cell.

To serve images straight off the database, simply read the files into memory using a SELECT query, set the content-type header in your application to the mime-type of the image, say image/png, and write it to the stdout.

Try to debug your query by outputting to the stdout instead of sending to

mysql server. You can do it by simply echo()ing your query as it is to the
browser or terminal. I'm sure you'll see it doesn't look like what you
really

Will DELAYED inserts solve my problem ( also related to indexing )
I have a hit logger tool, which does approximately 200,000 INSERTs a day into tables. The other application uses the same tables to run somewhat complex SELECT queries. Since these tables will be large, SELECT queries are quite slow. Indexing the tables produced prefect results for these SELECT queries. But I guess inserting into a large indexed table may be a lot slower? So my question is, may DELAYED inserts solve my problem here, and allow me to keep those tables indexed?

RE: MySQL with perl error
The only reason why that might happen (assuming it is working somewhere else),
the object isn't return. So connect() constructor couldn't return the object.
To read the error message from DBI, you'll have to read $DBI::errstr:
my $dbh = DBI-connect(dsn, login, password) or die $DBI::errstr;
If the program passes the above line without errors, you'll not have that error
message.
another way of doing the above is:
my $dbh = DBI-connect(dsn, login, password, {RaiseError=});

hi.
assuming all inserts and updates never specify a value for UpdatedDate or
CreationDate, on the initial insert:
mysql insert into table (Info) values ('blahblahblah');
they will both be set to '20010627125429' or something.
any subsequent updates:
mysql update table set Info='somethingelse' where Info='blahblahblah';
will leave CreationDate as its original value, and change UpdatedDate to
whatever the current timestamp is because it is first in the table
description/create definition.

Wait, I didn't get the following:
an alternate solution is to have a table like this:
Create table(
UpdatedDatetimestamp(14),
CreationDatetimestamp(14),
Infovarchar(100)
);
as mysql only automatically updates the _first_ timestamp column in a
table.
. Could you tell me more about it? And how does it solve thr problem?

I, c. Then you just have to INSERT INTO it NOW() manually, that works

TIMESTAMP is not the solution to his problem; he wants the date to
default to now() when the record is created, not updated.
There's currently no way to do this in MySQL; default values must be
constants.

hi.
check out the TIMESTAMP column type...maybe TIMESTAMP(14) as the
column
type?
you can then format the date accordingly with...uh...DATE_FORMAT() in
your
select statements...

Subject: Creating Table with a Default Datetime field
How do I get a default date time in the create table clause...
I have tried
Create table(
CreationDateDATETIMEDEFAULT NOW(),
Infovarchar(100)
);
Create table(
CreationDateDATETIMEDEFAULT NOW(),
Infovarchar(100)
);
Create table(
CreationDateDATETIMEDEFAULT SYSDATE(),
Infovarchar(100)
);
Create table(
CreationDateDATETIMEDEFAULT SYSDATE(),
Infovarchar(100)
);
Create table(
CreationDateDATETIMEDEFAULT CURRENT_DATE(),
Infovarchar(100)
);
Create table(
CreationDateDATETIMEDEFAULT CURRENT_DATE(),
Infovarchar(100)
);
All without the quote return with invalid syntax.
With the quote inserts 000-00-00 00:00:00 meaining invalid date.

Re: Default Datetime?
But how about TIMESTAMP? For example: CREATE TABLE time_test (creation_date TIMESTAMP, info VARCHAR(100)); This should work fine too,doesn't it? -sherzodR On Tue, 26 Jun 2001, Paul DuBois wrote: At 2:43 PM -0400 6/26/01, Richard Bates wrote: How do I get a default date time in the create table clause...

mySQL design for the questionnaire
As a student CGI programmer, I've been working on an online questionnaire.
I have been working so hard to design the mysql db part, still I'm not
sure if I've done it right. Still somethings seem to be awkward.
Here I'm DESCRIBing the tables for you, then i'm explaining how I
inteded to use it:
mysql DESC cral2_questions;
+-+---+--+-+-++-+
| Field | Type | Null | Key | Default | Extra
+-+---+--+-+-++-+
| question_id | int(10) unsigned | | PRI | NULL| auto_increment
| question| text | | | |
| type| enum('r','c','t') | | | r |
| calculate | enum('yes','no') | YES | | NULL|
+-+---+--+-+-++-+
4 rows in set (0.01 sec)
mysql DESC cral2_answers;
++--+--+-+-+---+-+
| Field | Type | Null | Key | Default | Extra |
++--+--+-+-+---+-+
| answer_id | int(10) unsigned | | | 0 | |
| question_id| int(10) unsigned | | | 0 | |
| answer | char(200)| | | | |
| if_checked | int(10) unsigned | YES | | NULL| |
| if_not_checked | int(10) unsigned | YES | | NULL| |
++--+--+-+-+---+-+
5 rows in set (0.00 sec)
The first table stores questions and the second one stores their answers.
If you look at the type column, r stands for RADIO BUTTONED, which means
only one of the options could be checked, c means CHECK BOXED or CHECK
ALL THAT APPLY type of questions, and t stands for TEXT FIELDED, and
respondent would have to type something in, which will be matched agains
a respective REGEXP.
CGI script also calculates the results, and provides an instant feedback
depending on the score a student gets. Of course in addition to the above
tables, I'll be needing a table for storing each students information by
assigning an auto_incrementing number for each student, storing the the
students answers, answer key table.
Do you guys think I'm making it too much complicated? I can give you the
link for the initial step of the application. I developed it for the
experts where they rated and provided feedback for each item, according to
which we had to fine-tune the questions. Since we have the fine-tuned
questions now, I started working on the final part (for students).
URL: http://www.ultracgis.com/cgi-bin/cral.v1.cgi
You can access the questionnaire from here. And the control panel is at
http://www.ultracgis.com/cgi-bin/cral.v1.cgi/ControlPanel
I really need experts ideas.
Thank you
