Joining two tables based on dates

Hi,

I want to accomplish something which I think is very simple: Joining tables based on dates.

Let's say I have the following tables:

Table1 - which has the following columns: Group1, event_date.

Table2 - which has the following columns: Group2, start_date, end_date.

I want the join to work as follows: (Group1 == Group2) AND (start_date < date < end_date)

How can I accomplish this using a JSL code?

Thanks

Data TableRe: Joining two tables based on dates

I think it will be easiest to Query for this and write some SQL for the join

Names Default To Here(1);
// Using aliases, performing a join
dtSAT = Open("$SAMPLE_DATA/SATByYear.jmp", Invisible);
dtUS = Open("$SAMPLE_DATA/US Demographics.jmp", Invisible);
Query(
 Table(dtSAT, "t1"),
 Table(dtUS, "t2"), 

 "\[SELECT t1.State, t1."SAT Math", t2."College Degrees",
            t2."Eighth Grade Math"
       FROM t1
       LEFT OUTER JOIN t2
           ON t1.State = t2.State
       WHERE t1.'SAT Math' > 550;
      ]\"
);

It isn't the only option but it should be fairly simple and easy to understand (if you know SQL).

Perfect! I didn't know you can work with SQL syntax within JMP. This will make my life a lot easier from now on.

Thank you
