sql server - multiple SQL counts using multiple queries using SQL -


i need multiple counts. have 6 columns. this:

select  count(c.id) 'column 1', count(c.id) 'column 2', count(c.id) 'column 3', count(c.id) 'column 4', contact c 

i need able run different counts using different queries unsure how apply queries counts in 1 result.

you have several options here.

1) use subqueries @thesoultion proposed

2) use use union

   select 'a' name, count(c.id) [count] contact c ...     union    select 'b' name, count(c.id) [count] contact c ...  

3) in case same subset want sum based on conditions, use case when inside counts

 select sum(case ... when ... 1 else 0 end) counta,         sum(case ... when ... 1 else 0 end) countb  ... ...
