Most Efficient Way To Count Subset Of Rows In A Table?
Sep 14, 2005Hi all,
I’ve a table with production objects, and another with possible items composition of the object. I need to count how many occurrences of each standard composition appears:
Table PROD:
PROD_ID COMPONENT TYPE
--------- ----------- -----
1 AAA X1 BBB Y2 AAA X3 BBB Y4 AAA Y5 AAA X5 BBB YTable ITEM_COMPITEM_ID COMPONENT TYPE-------- --------- -----7 AAA X7 BBB Y8 AAA X9 BBB Y
The result should be:
ITEM_ID OCCURRENCES-------- ----7 28 19 1
Table PROD have millions of rows, my way is too slow (I’ve a loop where each PROD object are separately queried against the ITEM_COMP), some have an idea for a most efficient way?

SQL Call To Count The Total Rows In Table B For Each User In Table A
Jan 17, 2006I have 2 tables:
TableA:
Name
UserA
UserB
UserC
Table B:
Name Data
UserA xxx
UserB asdasd
UserB ewrsad
UserC dsafasc
UserA sdf
UserB dfvr4
I want to count the total entries in Table B for every user in Table A. The output would be:
Name Count
UserA 2
UserB 3
UserC 1
I can use a Select Count statement, but I will have to make a SQL call for every user in Table A. Also, Table A is dynamic, so the users are always changing. Can this be incorporated into one SQL call to count the total rows in Table B for each user in Table A?

Getting The Number Pf Rows In A Query Result
Sep 1, 2004My site have a complicated search, the search give the results in two stages- the first one giving the number of results in each section:
"In the forums there is X results for the word X
In the articles there is X results...."
And when the user click one of those lines, the list shows the specific results in that section.
My problem is that I don't know how to calculate the first part, for now I use dataset, and table.rows.count to show the number of results in each section. Since my site have more then ten, it looks like a great waste to fill such large dataset (in some words it can be thousands of rows in each section) only for getting the number of rows…
Are there is a sql procedure or key word that will give me only the number of results (the number of times that specific word showing in the columns?)
Great thanks
