SQL

SELECT  a.Name,
        a.id,
        a.Type,
        a.date,
        COUNT(b.pac),
        a.ConName
        FROM    TableA a
        JOIN    TableB b ON a.Taskgenid = b.Taskgenid
        AND a.formgenid = b.formgenid
        JOIN    TableC c ON A.id = c.ID
        JOIN    TableD d ON D.Typeid = c.Typeid
        WHERE   a.date BETWEEN @Begindate AND @Enddate
        AND a.type IN (1, 2, 3)
        GROUP BY a.Name,
        a.id,
        a.Type,
        a.date,
        a.ConName

I don't want to group the columns a.id,a.type,a.date,a.conname. If I remove those columns it showing error that a.id, a.type,a.date,a.conname is not group by or aggregate.

I want only Count(b.pac) in select statement.

SELECT COUNT(b.pac)
FROM TableA a
JOIN TableB b ON a.Taskgenid = b.Taskgenid
AND a.formgenid = b.formgenid
JOIN TableC c ON A.id = c.ID
JOIN TableD d ON D.Typeid = c.Typeid
WHERE a.date BETWEEN @Begindate AND @Enddate
AND a.type IN (1, 2, 3)

If you want the columns you have to group by them, or you can do your grouping in a nested or derived table and then join to it to get your other columns.

If you want only b.pac value by using group by then u have to use joins.... check the solution Below..

SQL

Select * From
(
SELECT  a.Name,COUNT(b.pac) as PacCount
FROM    TableA a
JOIN    TableB b ON a.Taskgenid = b.Taskgenid
AND a.formgenid = b.formgenid
JOIN    TableC c ON A.id = c.ID
JOIN    TableD d ON D.Typeid = c.Typeid
WHERE   a.date BETWEEN @Begindate AND @Enddate
AND a.type IN (1, 2, 3)
GROUP BY a.Name   --- Assumed that u want group by Name, if not u can change it.
) GroupTable gt
join -- u can use the Join based on the table type relation
(SELECT  a.Name,a.id,a.Type,a.date,a.ConName
FROM    TableA a
JOIN    TableB b ON a.Taskgenid = b.Taskgenid
AND a.formgenid = b.formgenid
JOIN    TableC c ON A.id = c.ID
JOIN    TableD d ON D.Typeid = c.Typeid
WHERE   a.date BETWEEN @Begindate AND @Enddate
AND a.type IN (1, 2, 3)) BaseTable bt 
on bt.Name=gt.Name -- Relation between GrouTable and BaseTable...
