SQL Query to Count the Number of People who qualify required criteria - sql

Question

I am working on a project that has multiple agents and members. Now I have to do the following (through a SQL Query):
Select agents and members under a Parent Agent who have made payments, in full (amounting to total of 430, i.e. 130+150+150) for 3 months.
Each Agent has n-number of members, so for each agent I need to check if all the members have paid their 3month dues.
If dues are paid, return the total member count agent wise for the parent agent.
I have tried the following query, but no luck:
CREATE TABLE [dbo].[SlipDetails](
[SlipDetailsID] [int] IDENTITY(1,1) NOT NULL,
[SlipID] [int] NULL,

Query:
SELECT COUNT(dbo.MemberMaster.MemberID) AS CMemberID
FROM dbo.SlipDetails
INNER JOIN dbo.MemberMaster ON dbo.SlipDetails.MemberID = dbo.MemberMaster.MemberID
WHERE dbo.MemberMaster.AgentID = 203
GROUP BY dbo.MemberMaster.AgentID,
dbo.SlipDetails.MonthAmount
HAVING(SUM(dbo.SlipDetails.MonthAmount) >= 430);
How do I get the Exact Count for the members under each agent? Any help would be great.

Answer 1

Select mm.AgentName,Count(mm.MemberID) as MemberCount from MemberMaster mm
INNER JOIN
(Select AgentID,MemberId from SlipDetails
group by AgentID,MemberID
having Sum(MonthAmount)>=430)sd
on sd.AgentID=mm.AgentID and sd.MemberID=mm.MemberID
Group by mm.AgentID, mm.AgentName
or even:
Select am.AgentName,MemberCount from AgentMaster am
inner join
(Select mm.AgentID,Count(mm.MemberID) as MemberCount from MemberMaster mm
INNER JOIN
(Select AgentID,MemberId from SlipDetails
group by AgentID,MemberID
having Sum(MonthAmount)>=430)sd
on sd.AgentID=mm.AgentID and sd.MemberID=mm.MemberID
Group by mm.AgentID)mm1
on am.AgentID=mm1.AgentID

Answer 2

Try this
WITH SlipDetails_ttl as (
Select st.MemberID, sum(MonthAmount) as MonthAmount_ttl
from SlipDetails as st
group by st.MemberID
having sum(MonthAmount)>=430
)
Select am.AgentID, count(stt.MemberID)
From SlipDetails_ttl as stt
join MemberMaster as mm on mm.MemberID = stt.MemberID
join AgentMaster as am on mm.AgentID = am.AgentID
group by am.AgentID

Answer 3

Give this a try:
SELECT agt.AgentID, COUNT(*)
FROM dbo.AgentMaster agt -- Get all agents
INNER JOIN dbo.MemberMaster mbr ON agt.AgentID = mbr.AgentID -- Get each agents' members
INNER JOIN dbo.SlipDetails slp ON mbr.MemberID = slp.MemberID -- Get payment details for members
GROUP BY agt.AgentID
HAVING(SUM(slp.MonthAmount)) = 430 -- Only return members that have paid 430
A few assumptions/notes:
only looks at each agent's immediate members (not recursive, one level only)
does not factor in 3-month constraint, only checks that 430 has been paid per member
