I have a MS SQL table where one field is common for some of the records (link) and I need to calculate the count of some other fields in that same table based upon the case value of those fields but for only the distinct records. For example...
id = record id
link =common id
type = case
id = 1, link = 1, type = "out"
id = 2, link = 1, type = "out"
id = 3, link = 1, type = "out"
id = 4, link = 2, type = "out"
id = 5, link = 2, type = "out"
id = 6, link = 3, type = "in"
id = 7, link = 3, type = "in"
id = 8, link = 3, type = "in"
id = 9, link = 4, type = "out"
id = 10, link = 4, type = "out"
Results that I need
link count = 4
case "out" count = 3
case "in" count = 1
Can this be done using a single query statement?
