MYSQL :: Count Time

Looking For Query To Get Time Of Last Column Count Increase
Code:

id | time | units
------------------------------------
1 | 2009-01-06 06:52:32 | 50
1 | 2009-01-02 16:45:23 | 50
1 | 2009-01-02 09:12:16 | 40
1 | 2009-01-01 12:06:00 | 35
2 | 2009-01-04 14:52:30 | 259
2 | 2009-01-04 04:52:30 | 258
2 | 2009-01-03 18:00:01 | 258

I need to write a query that will, for each unique id, return the last time there was an increase in the "units" column. So for this data set, I want to see:

Code:

id | time
------------------------------------
1 | 2009-01-02 16:45:23
2 | 2009-01-04 14:52:30

PHP/MySQL Sorting By Date & Time (using Non Military Time)
This is probably a simple issue but I have searched online and can't find an answer.

I am using PHP/MySQL and I guess the most intuitive would be to have three select boxes containing HOUR / MINUTE / AM,PM option. Then store the time into mysql using there functions so I can output the data sorting them all by date and time. All the examples I have seen are for military time only but I'm sure there has got to be a simple mysql function or php function that converts non military to military and a formatting function to display with the AM / PM. But I have not found it.

But is not working. May I know what is the correct way of doing it?

#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.

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 ......

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:

How To Retrieve Mean Time Between Time Stamps
I have a table that stores failure information of external application. The time stamp of every failure event is stored. Now I'd like to make some system performance & reliability statistics calculations based on time stamps in certain recordset; mean time between failure MTBF, down time DT, etc.

Example:

2007-09-27 12:23:52
2007-09-27 08:50:23
2007-09-26 23:31:34
2007-09-26 21:45:33

Here the times between are (hours:mins): 3:33, 9:18, 1:46 and MTBF=4:52

Any effective possibility to make this example within a single query - or a procedure is needed?

Date-time Overlaps Another Time
had a time question in mysql...
i have a start and end time for a meeting table and i am comparing whether a new meeting conflicts with another meeting in same room on the same date.
i was wondering if i could check whether the 'date-time duration' in anyway overlaps another meetings date-time duration. visualized below...
............|____compareToThisMeeting__|
.....|_________meetingNewOverlaps__________|
i was doing something dumb before i realized i needed soemthing more complex (checking whether the start time of new meeting was 'BETWEEN' the start and end times of a meeting and whether the end time time is as well but i forgot the duration/middle value hehe).
(using asp)
and just returning booleans with a mySQL SELECT statement is what i am looking for like...
//within a loop in asp for meetings on same date/room
"SELECT '"+ year+"-"+month +"-"+day +" " + startHourString +":" + startMinuteString +":00''"+ " BETWEEN '"+ thisMeetingStart +"' AND '"+ thisMeetingEnd +"'"; (this doesnt cover the 'middle' overlap areas though)

Count(*) As Count And TotalCount Of Count
data in myTable1

(n) country_id
(1) 3
(2) 1
(41) 1
(5) 2
(6) 3
(7) 4

data in myTable4

(time) param
(10 : 10) c=4
(10 : 12) c=2
(10 : 30) n=41&k=5
(10 : 35) c=1
(10 : 37) n=5
(10 : 50) c=2
(10 : 54) c=2
(10 : 55) n=1&cate=6
(11 : 12) c=2
(11 : 15) n=7
(11 : 20) c=1
I have data in myTables like the above.

I have the following code.

code

(select left(time,2) as hour, count(*) as count
from myTable4
where

left(param,1)='c'
and
substring(param,3,1)=2

group by left(time,2)
)
UNION all
(select left(time,2) as hour, count(*) as count
from myTable4,myTable1

where
left(param,1)='n'
and
substring(substring_index(param, '&', 1) ,3)=myTable1.n
and
myTable1.country_id=2
group by left(time,2)
)

order by hour
And the code above produces the following result.

result

(day) count
(10) 3
(10) 1
(11) 1
The following would-be code doesn't work correctly, but it will show what I want.

would-be code

(select left(time,2) as hour, count(*) as count,
sum(count) as totalCount
from myTable4
where

left(param,1)='c'

)
UNION all
(select left(time,2) as hour, count(*) as count,

and
substring(substring_index(param, '&', 1) ,3)=myTable1.n

How To Fix "Column Count Doesn't Match Value Count At Row 1" ?
I've been trying to install a portal to my installation of Invision Power Board, and I keep coming up with this problem. I post here for two reasons: firstly is that no one is responding over at the portal creator's thread and I need help, second is that this error looks like a mySQL error that could be solved without the need of the creator if possible.

Here is the error returned:

Count(*) In A Select Returns "1". It Should Behave Like Select Count(*)
i'm trying to make a query work properly but I got lost:

SELECT *,count(*)
FROM cancons c, musics m, discos d, r_discos_cancons rdc
WHERE c.c_id_music = m.m_id
AND rdc.rdc_id_disc = d.d_id
AND d.d_id_music = m.m_id
AND m.m_id = 24
GROUP BY c_id

note:
cancons (ca) = songs (en)
discos (ca) = cd's (en)
music (ca) = musician (en)

don't worry for the WHERE part. i need it because of the foreign keys.
this query returns a table with the title of the song and some more data. on the right side, I get another column called "count(c_id)" with the number "1" in it for each row. That's supposed to be due to the "group by" clause, I think.

I'd like to get the table with the songs, as usual, and, with the same query, I'd like to get the total number of rows selected.

Time Out, ASP
I don't know if it's inefficient vbscripting, a slow server, a badly organised database or some other reason, but...

Relatively simple scripts on our unix server keep timing out, and this is even after beefing up the time out to 120 seconds! The scripts don't seem to be doing much, although whenever one or more tables are referenced, the server takes ages and times out.

My method of querying is:

-check form data
-create a connection
-compose a sql string
-execute it to make a record set
-cycle thru the record set and copy data to arrays
-close the record set (+ set to nothing)
-close the connection (+ set to nothing)
-do the html, with data from the arrays, etc.

I used to open record sets separately, rather than on a connection, and also used to keep the record set open and cycle through it in the HTML rather than use arrays.

Two Queries At The Same Time?
I have 2 queries:

The {..} are precalculated values. At the beginning no item can be
matched by both where clauses.

1)
update tabelle
set L = L + {MOVE}
set R = R + {MOVE}
where L >= {LEFT} and R <= {RIGHT}

2)
update tabelle
set L = L - {DIFF}
set R = R - {DIFF}
where L >= {OTHERLEFT} and R <= {OTHERRIGHT}

My problem: If I run update 1 first, the update 2 can match items from
where clause 1 because the update changed the values from L and R so that
they can be found at where clause 2.

And if I run 2 first its the same in the other direction.

So how can I do the 2 where clauses first, and when mysql knows my items I
would like to update so no item gets updatet twice.

INSERT At A Time

per INSERT, i generate an id number, which is actually the
date and time, ie. 12321620041103

since its only the date and time,
if the 2 users logged in happen to do an INSERT at the same time,
will mysql only process one insert at a time, or will both
go thru at once?i dont want them to go thru at the same time, because they
will both have the same id number.
