Hi Guys,

I have attached a spreadsheet illustrating what I am trying to achieve with the desired query result. I know how to check if a record has rows in multiple tables and return the different row counts from the tables a rows using.

SELECT        COUNT(*) AS Count1
FROM            Table1
SELECT        COUNT(*) AS Count2
FROM            Table2
SELECT        COUNT(*) AS Count3
FROM            Table3
SELECT        COUNT(*) AS Count4
FROM            Table4
SELECT        COUNT(*) AS Count5
FROM            Table5

Could someone please help me right a query to produce my desired result as per my spreadsheet.

Many thanks in advance

this would look like something like this (starter)
select c.customer_name
  , ( select count(*) from tblService1 s where s.customer_ID = c.customer_ID and s.active = 'Yes' ) service_1
  , ( select count(*) from tblService2 s where s.customer_ID = c.customer_ID and s.active = 'Yes' ) service_2
  , ( select count(*) from tblService3 s where s.customer_ID = c.customer_ID and s.active = 'Yes' ) service_3
  , ( select count(*) from tblService4 s where s.customer_ID = c.customer_ID and s.active = 'Yes' ) service_4
  , ( select count(*) from tblService5 s where s.customer_ID = c.customer_ID and s.active = 'Yes' ) service_5
  from tblCustomers c
