Order By Question

However, the table has multiple columns in it and I only want one column in the result set.

Re: Order By Question
Hi, the basic thing is that you must never assume anything on what order you're getting your rows back if you're not using an order by. This said I guess one way for you to do this is to add a row-number column, preferbly auto-increment, and then order by that column. /Johan Schimmel LCpl Robert B wrote: I am having a problem with using a select statement to retrieve a result set in a particular order.

Re: SELECT question - query for records over a series of dates
I think you might be one to something here... is there such a thing as a while loop in MySQL? i.e. can I fill a table with data via a MySQL query? I guess I could do it via PHP... I could create a temp table with one column of dates for the range I am looking for and then LEFT JOIN my log table and match the dates. Having a dedicated table would work but would be kind of a waste of space / resources. These queries will not be run that often.

Now you can use something like this: SELECT dates.date, COUNT(*) as hits FROM dates LEFT JOIN table on dates.date = DATE(table.date_impression) WHERE dates.date BETWEEN '2005-08-12' AND '2005-08-16' GROUP BY dates.date; Populating the dates table initially is a small (one-time) pain.

Show table status
Hello, Does anyone know where (c-api functions perhaps) SHOW TABLE STATUS gets its info from? Specifically, the new columns added in 4.1.2 and 4.1.3, are they the result of underlying c-function changes, new functions, or something else.

prepared statement problems
Greetings,
I am trying to figure out prepared statements in the C-API. The problem
I am having is passing parameters to a prepared statement.
If I hard code everything in my SQL statement, like:
static char *sql_stmt = {
select product
from lth
where facility = \XTEX6\
and lot = \5025267\
and trn = \LOGI\
};
everything works fine. However, if I attempt to pass facility and lot
as parameters:
static char *sql_stmt = {
select product
from lth
where facility = ?
and lot = ?
and trn = \LOGI\
};
I am unable to get any data back. I have enclosed my source code
below. Does anyone see where I have made a mistake that would prevent
this from working properly.
Sorry for the length. I will greatly appreciate any assistance I can get.
Regards,
Darrell

Re: SELECT question - query for records over a series of dates
Dan Tappin wrote: I think you might be one to something here... is there such a thing as a while loop in MySQL? i.e. can I fill a table with data via a MySQL query? I guess I could do it via PHP... I could create a temp table with one column of dates for the range I am looking for and then LEFT JOIN my log table and match the dates. Having a dedicated table would work but would be kind of a waste of space / resources. These queries will not be run that often. Dan T No while loop, but this can be done in mysql, so long as you already have a table with enough rows. For example, to create and fill a dates table, starting with 1995-01-01 and ending with 2005-12-31: # create the table with 2 extra columns, one of which is auto_increment: CREATE TABLE dates (id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, date DATE, junk INT, UNIQUE date_idx (date) ); # add enough rows to the table to cover the desired date range: INSERT INTO dates (junk) SELECT id FROM big_table LIMIT 4018; # use the auto_increment generated ids as offsets from the start # date to fill the date column: UPDATE DATES SET date = '1994-12-31' + INTERVAL id DAY; # drop the now useless, extra columns: ALTER TABLE dates DROP COLUMN id, DROP COLUMN junk; Voila, dates has one row for each day from 1995-01-01 to 2005-12-31. This example MyISAM table with 10 years worth of rows in it takes up 63,461 bytes on my disk, including the index. If that's a waste of space / resources, I think it's time to buy more disk. You certainly could create such a table on the fly, with just the rows you need, as a temporary table, but that will be relatively slow compared to simply using a pre-existing, dedicated table to satisfy your queries. Besides, at that small size, I don't really see the downside.

Subquery returns more than 1 row (1242)
Hi guys:
I work with some grassroot communities, which we have to keep following up. And
we need to know how the population changes in the different years.
What I figured out is to have two tables: one to have the name of the
organization, and the second which contains the changes in the time.
To avoid people having to input the stored data each time (and just update from
the stored data), I am trying to create a query which inserts (re-inserts) the
primary key of the primary table into the Foreign Key field of the secondary
table, adding the current year, and then the user just have to update the
information and it has the year collected from a form variable.
The query is as follows:
INSERT INTO tbl_secondary( FK_ORG, year )
VALUES (
(SELECT PK_ORG
FROM tbl_primary
WHERE Province = 'Province1'), 2006
)
It gives me the following error message: 1242. Subquery returns more than 1
row
If I try to do the following query it works, but it is not useful for me
because we need to insert the data with its especific year (timestamp is not
useful as well):
INSERT INTO tbl_secondary( FK_ORG )
(
SELECT PK_ORG
FROM tbl_primary
WHERE Province = 'Province1'
)
How could I override this problem?.
Does anybody has a better idea in how to manage this information storage?.
Thanks a lot, and very best regards for all of you.
Alvaro Cobo.

RE: prepared statement problems
Hi,
The problem here is that you have two input bind variables, but you
declaring MysQL BIND array as parm_bind[1], which can hold only one input
bind variable. Make it parm_bind[2]. That should work.

I see this EXISTS but not an example of how to use it with INSERT. I see INSERT... ON DUPLICATE KEY UPDATE col_name=expr which is very close, but I want it to do nothing on duplicate key. :( Perhaps you could update using the same value? Eg: INSERT ... ON DUPLICATE KEY UPDATE col_name=col_name If you're worried about side-effects (eg; updating a timestamp column incorrectly), I believe that MySQL will not perform the update if the column value does not change. steve mysqladmin Ver 8.40 Distrib 4.0.24, for pc-linux-gnu on i386 CREATE TABLE `release_test` ( `BID` int(10) unsigned NOT NULL default '0', `ReleaseID` smallint(5) unsigned NOT NULL default '0', `Tested` tinyint(1) unsigned NOT NULL default '0', `CoreID` smallint(3) unsigned NOT NULL default '0', KEY `BID` (`BID`,`ReleaseID`), KEY `ReleaseID` (`ReleaseID`) ) TYPE=MyISAM; -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED] -- +--- my people are the people of the dessert, ---+ | Steve Edberghttp://pgfsun.ucdavis.edu/ | | UC Davis Genome Center[EMAIL PROTECTED] | | Bioinformatics programming/database/sysadmin (530)754-9127 | + said t e lawrence, picking up his fork + -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
