TQuery help

Hello DigitalNam,

  what is the value of Total MP3 / MPG ?
  also, what is the Total Credit MP3 / MPG ?
  I mean, how are they calculated?
  do you want count(), sum()  and what is the rule to count() / sum() the mp3/mpg ...

Regards,

angelIII

Hi !

It is not clear, how to find where the credit belongs(mp3 or mpg).
What is the key field for totals(ID ?).

regards,

Angelll:

When the user plays a mp3 for example, the album song name etc is added to the db with the value of the credit for a mp3 or mpg. So what I want is to give the user a summary of the total credits where field is MP3 of total credits where field is MPG for a certain period.
This is how my db looks at the moment.

ID      Date      Time      Album      Artist      Song      MP3      MPG      FileName      Credit
294      28/03/2007      22:42:02      Anastacia      Anastacia      Welcome to My Truth      Yes      No      07 Welcome to My Truth Anastacia Anastacia Rock 12      1
295      28/03/2007      22:42:13                        No      Yes      Metallica - The Unforgiven II.mpg      5

select sum(iif(MP3=Yes,1,0)) TotalMP3
,sum(iif(MPG=Yes,1,0)) TotalMPG
,sum(iif(MP3=Yes,Credit,0)) TotalCreditMP3
,sum(iif(MPG=Yes,Credit,0)) TotalCreditMPG
from yourtable

Angel gives me syntax error (missing operator) in sum(iif(MP3=Yes,1,0)) TotalMP3. How can I get the returned values to display in normal labels?

and how can we base the query on a certain time period? with a calendar dropdown?

in case the field MP3/MPG are boolean, use True instead of yes.
if its a string field, use 'Yes' instead
possible also, you need to use ; instead of ,   that depends on some regional settings

>How can I get the returned values to display in normal labels?
labels can have a data source also.
ie, make the above query a view (querydef) etc...

Angel, got it wo work, like with the following

select sum(iif(MP3=True,1,0)) AS TotalMP3 , sum(iif(MPG=True,1,0)) AS TotalMPG , sum(iif(MP3=True,Credit,0)) AS TotalCreditMP3 ,sum(iif(MPG=True,Credit,0)) AS TotalCreditMPG from STATS

Seems like the AS was missing. Regarding the label question, I really don't understand your answer. I don't want to display the values returned by the query in a DBgrid, but all in labels.

Ok, I have managed to get the values to TLabel like this

Label22.Caption := 'Total for MPG: ' + IntToStr(DM.Query.Fields[1].AsInteger);

But now how do I get it to show from the 01/01/2007 to 03/01/2007?

Thanks for the help Angelll... Saved me heaps of time...
