Question

I have two tables:

Table 1: ID, PersonCode, Name,

Table 2: ID, Table1ID, Location, ServiceDate

I’ve got a query joining table 1 to table 2 on table1.ID = table2.Table1ID where PersonCode = ‘XYZ’

What I want to do is return Table1.PersonCode,Table1.Name, Table2.Location, Table2.ServiceDate, I don’t want all rows, In table 2 I’m only interested in the row with the most recent ServiceDate for each location. How would I go about doing this?

Answer 1

Something like this:

SELECT     Table1.PersonCode, Table1.Name, Table2.Location, MAX(Table2.ServiceDate) FROM     Table1      INNER JOIN Table2 on Table1.ID = Table2.Table1ID  WHERE     TABLE1.PersonCode = 'XYZ' GROUP BY     Table1.PersonCode,Table1.Name, Table2.Location
