Question

I have Table A and Table B

**Table A** 
Claim_ID PK

**Table B** 
Claim_State_ID
Claim_ID FK
Claim State
Claim_State_Start_Date
Claim_State_End_Date

Table A can have many Table B

Claim State can have three values: Terminated, Submitted and Payment Complete.

Is it possible for me to do a select on Table A.Claim_ID where the Claim State is Terminated but the previous state must be Payment complete. I would do this by checking the Start and End Dates.

Essentially, I need to only select the Claims where the state is terminated but the state sometime before this is Terminated and not submitted.

I don’t have data at the moment but this would be my logical attempt.

Select COUNT (Claim_ID) from TableA JOIN TableB On TableA.Claim_ID=TableB.Claim_ID Where TableB.Claim_State ="Terminated" and Claim_State_End_Date

The statement is cut short here as I need to compare the date to the date of Send to Payment state.

Is this even possible?

Forgive the archaic join syntax. I prefer it, for some reason…

I think you’re asking “find all claims where there’s a record showing it’s terminated, and another record showing it’s paid, and the termination date is greater than the paid date.”

select a.claim_ID
from   TableA a, 
       TableB term, 
       TableB paid
where  a.claim_id  =  term.claim_id
and    a.claim_id  =  paid.claim_id
and    term.Claim State  = 'TERMINATED'
and    paid.Claim State  = 'PAID'
and    term.Claim_State_Start_Date >= paid.Claim_State_Start_Date
