#1136 - Column Count Doesn't Match Value Count At Row 1
I'm getting the above error with the following SQL Statement. I cannot seem to find the error in the code. The select statement does pull multiple rows. I'm using my SQL version: 4.1.19 Any clue on why this isn't working? INSERT INTO `Grants` ( `Project_Code` , `Grant_Code` , `Fiscal_Year` , `Capital` ) VALUES ( ( SELECT Project_Code, Grant_Code, FY, SUM( Capital ) FROM Grants_Temp WHERE Project_Code = 'OSUT' AND FY = '2006' AND Claim_Month = '072006' GROUP BY Grant_Code ORDER BY Grant_Code ) )

Column Count Doesn't Match Value Count At Row 1
I am getting the following error when I run my query. Column count doesn't match value count at row 1 I have looked up this error and have checked and I appear to have the right number and names in my query. In the DB table I have 34 columns, and that is what I have in the query. The last 4 in the query are for the names of the images being uploaded, but am not sure how this all works, so I don't know if I need them, but have them there until I know for sure. Comment, Purchase and Remarks are not used in this form, but I have added them so everything is being shown in the query. Code:

Trying To Get Total Count Plus Count From WHERE Clause In One Query
I am fairly familiar with mysql, have been using it with php for about a year now for my development work. One query I am stuck on is the following. I am doing reporting, and need to find the count from a WHERE clause compared to the total count for that group. For the sake of an example, let's say I have a prize table that contains a complete list of prizes. There is a column to list if the prize has been won or not (prizeUsed - Y or N) and another that has the prize name (prizeName - string). I want the final result to list something like: Total Prizes ____________________ 100 of 850 ......

'Time' Column Type
Okay I have a column setup in one of my tables as the 'time' data type. It has a couple records like: 12:00:00 14:30:00 07:00:00 12:00:00 and when I view the data on my ASP page it puts this out: 1/5/2003 12:00:00 PM 1/5/2003 2:30:00 PM 1/5/2003 7:00:00 AM etc... The main question i had was why is it throwing the current date in there? And how do I get rid of it? Also is there a way for it to remain in 24-Hour format?

(RIGHT(column,4)*COUNT(*)
I am having an issue with one column in my table that is associated with a dollar amount. (E.g. $6.00 or $26.00) I am trying to create a query that will take the total count of matching orders and multiply it by the order total. Example Query: SELECT *,COUNT(*) AS Count,(RIGHT(ordertotal,4)*COUNT(*)) AS total_rev FROM `table` WHERE (table.pkg_number <> '5%') GROUP BY pkg_number; The query gives me accurate results for any dollar amounts that are $9.00 and lower. I then change the (RIGHT(ordertotal,4)*COUNT(*)) to read (RIGHT(ordertotal,5)*COUNT(*)) to get results for orders that are $99.00 and lower but the $9.00 and lower results are incorrect. I am very new at this, can anyone help me with a tip on how to combine them to get accurate results? Or is there a way to create the column in the table to handle dollar amounts more accurately. Currently I am using VARCHAR(25).

Increase Value In Record Set
I guess this is a newbie question I hope someone can help with.

Every game can have 1,000's of players and what I would like to do is determine their ranking like this: "select * from Players order by GameScore DESC" (Highest score wins) and then (and that's the tricky bit) Store their ranking in the field Ranking for the selected records without having to loop through all of them. Something like: "update Players set Ranking = ('one more then the previous player') order by GameScore DESC" Is that possible or is the only way to loop through these 1'000's of records one by one.

Find Users With Similar Tastes / Select Count Of Subquery & Maintain Column Assignmts
The ultimate goal of the query: List users by similarity in taste to user 1 based on the similarity of their favorite sites. Setup table users: id, etc. table sites: id, etc. table favorites: user_id, site_id Users add sites to their favorites list, a row is inserted into the favorites table associating users and sites. Criteria for "similarity of taste": %similarity = (number of intersecting favorites) / (number of unique favorites between them) My attempt: SELECT COUNT(*) / (SELECT COUNT(*) FROM (SELECT DISTINCT id FROM favorites WHERE favorites.user_id = u2.id OR favorites.user_id = 1) as unique_favs) as p_match, u2.* FROM favorites as f1 JOIN favorites as f2 ON f2.site_id = f1.site_id AND f2.user_id != 1 JOIN users as u2 ON u2.id = f2.user_id WHERE f1.user_id = 1 GROUP BY u2.id ORDER BY p_match DESC LIMIT 30 The error: Unknown column 'u2.id' in 'where clause' Apparently column associations are "forgotten" when doing a derived table subquery.

Cannot Increase MYSQL Ram Usage

Limiting Query Time
Is it possible to limit the query time in MySQL (3.x or 4.0)? For example, I'd like to have any query that takes more than a specified number of seconds just quit automatically. Seems dumb, but on a web site, nobody is going to wait minutes for a query to return so they refresh anyway. So on a busy server, MySQL ends up with several queries running that all take a long time to finish which compound to make it even slower. A simple time limit would solve the problem. Yes, I know that the queries should take less time, but again, on a busy server, sometimes the longer queries do take a long time (10 minutes or more) to complete.

Execute Time Of A Query
I'm running a SELECT * query on a table with over 3,000 rows. I need to know the execute time on the query. PHPMyAdmin shows it to me, but because they automatically add a LIMIT 0, 30 I suspect the time is only for those 30 records. It also has a feature to prevent web server timeouts that prevents me from setting the LIMIT to 0, 3100. BTW, I'm programming in PHP. Does the time to run the query get automatically passed when PHP sends the query to MySQL? <? PHP $Query = "select * from my_table where 1"; $Result = MYSQL_QUERY($Query); ?>
