Simplying a few MySQL Queries - Help Needed

[CommuneZoom]

I have the following queries that, if possible, I need to simplify. I'd like to knock this down to as few queries as possible as I will need to call additional (probably 2 other items) from the same row.

I am just looking to get the number of rows matching each set, though I'd rather knock 4 queries down to 1-2 if there is another way to do so.



Code:
---------------
Code is only visible to licensed users, and only when logged into the forums.
---------------



Is there an alternative, of will I be stuck making 4 seperate calls?

Try the below, maybe it will work. I need to start coding php more, and stop with vb.net. I'm starting to forget stuff!

Thanks for the reply, however, I need them both to be showing at the same time and not alternating.

As I need it to report the total for the entire table, the above will not work. I have 8 entries in the table and the above reports a blank for active and 1 for pending (when all 8 are pending).

Try it without the Count clause. So...

I think the logic may be backwards in that, totalactive should be when ispending = 0.

Try ;

Can you explain this bit?

I've never seen this before...

[Marco van Herwaarden]

if the value of ispending is '1', it will result in a value of 1, otherwise 0 (zero), if you then sum it, you will count 1 for each row that have ispending = 1.

By testing ispending = 0, you can reverse the count.

Interesting question, is it quicker to use a more complicated SQL query, or a simpler query and a bit of PHP.

[Marco van Herwaarden]

That depends totally on the query. Since this one are simple embedded functions, not used in where/order by/join conditions, i would say the query is much faster then doing it in php.

Thanks Marco :)

can IF be used within the parameters of where?

[Marco van Herwaarden]

That wouldn't make much sense i think, the where clause is already 1 big if-statement, but i never tried.
