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;

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

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')

;
