Hello list

I'm a MSSQL convert and I'm running postgresql 7.2

I'm trying to create a statement in which display multiple counts on a table

In MSSQL I would use

select
count_1=(select count(ad_code) AS "CP" from leads where ad_code = '555'),
count_2=(select count(ad_code) AS HED" from leads where ad_code = '222'),
etc

I've searched the docs but to avail.

Any help, suggestions, pointers, would be appreciated

Thanks

Jeannie

SELECT
(select count(ad_code) AS "CP"
from leads where ad_code = '555') AS count_1,
(select count(ad_code) AS HED"
from leads where ad_code = '222') AS count_2,
...etc...

Or, if you want a count of every ad_code:

SELECT ad_code, COUNT(ad_code) FROM leads GROUP BY ad_code;

Re: multiple count functions in a select statement

If I understand what you're asking try:

select count_1, count_2 from
(select count(*) AS count_1 from leads where ad_code = '555'),
(select count(*) AS count_2 from leads where ad_code = '222')
;

Re: multiple count functions in a select statement

Sent a little too quickly the sql should look like this:

select count_1, count_2 from
(select count(*) AS count_1 from leads where ad_code = '555') AS DMY1,
(select count(*) AS count_2 from leads where ad_code = '222') AS DMY2
;
