Here is some sample data from the case_text table

company_id    case_id    text_type_code    case_text_seq
MIS                  1              Resolution             21
MIS                  1              Resolution             22
MIS                  2              Resolution             5
MIS                  2              Resolution             6
MIS                  2              Resolution             4

I am trying to create a query that will return the row with the highest case_text_seq value for a given combination of company_id,  case_id,  and  text_type_code    

Using the sample data above, I would like the query results to look like the following:

company_id    case_id    text_type_code    case_text_seq
MIS                  1              Resolution             22
MIS                  2              Resolution             6
