Join 2 Queries

Hi Guys,

I want to be able to combine two queries into 1 result set.

I have for example:

QUERY 1:
Select Distinct Name,Count(*) AS TotalCount
FROM Table1
WHERE
Condition1 > 0
Group BY Name
ORDER BY Name

QUERY2:

Select Distinct Name,Count(*) AS TotalCountWithCondition
FROM Table1
WHERE
Condition1 > 0
AND Condtion2 = 0
Group BY Name
ORDER BY Name

So basically query2 is a subset of Query1 with the extra condition "AND Condition2=0"

I want this to be displayed as 1 returned set, say with column headers like

Name|TotalCount|TotalCountWithCondition

Thanks in advance.

Normally you would UNION the results, don't know how well will this work with DISTINCT:

Select Distinct Name,Count(*) AS TotalCount
FROM Table1
WHERE 
Condition1 > 0
Group BY Name
ORDER BY Name
UNION
Select Count(*) AS TotalCountWithCondition
FROM Table1
WHERE 
Condition1 > 0
AND Condtion2 = 0 
Group BY Name
ORDER BY Name

HI,

pls try

SELECT T1.Name, T1.TotalCount, T2.TotalCountWithCondition
FROM(
SELECT Name, Count(Name) AS TotalCount, Condition1
FROM Table1
GROUP BY Name, Condition1
HAVING Condition1>0) as T1 LEFT JOIN (SELECT Name, Count(Name) AS TotalCountWithCondition
FROM Table1
GROUP BY Name, Condition1, Condition2
HAVING Condition1>0 AND Condition2=0) AS T2 ON T1.Name = T2.Name

select distinct

group by

WRONG

You NEVER need to add "distinct" if you are using a group by clause.

and,
I would choose skullnobrains to write this query :)
