A Tricky Join

[Giovane_BXB]

I'm having some trouble joining two tables as described below.

Let’s take the first table as follows:

Table 1

Name	Date
John	02/15/2024
Andrew	02/20/2024
Thomas	03/10/2024
Clark	03/12/2024
Jefferson	03/25/2024
Peter	04/01/2024
Susan	04/10/2024
Anderson	04/20/2024
Mary	04/25/2024
Joe	04/30/2024

Now, let’s take the second table:

Table 2

X	Y	Z	Parameter             Date
1	2	3	02/01/2024
4	5	6	02/15/2024
7	8	9	03/01/2024
10	11	12	03/15/2024
13	14	15	03/25/2024
16	17	18	03/30/2024
19	20	21	04/01/2024
22	23	24	04/08/2024
25	26	27	04/15/2024
28	29	30	04/20/2024

I need to add parameters X, Y, and Z to Table 1 as follows:

Table 1

Name	Date	X	Y	Z
John	02/15/2024	4	5	6
Andrew	02/20/2024	4	5	6
Thomas	03/10/2024	7	8	9
Clark	03/12/2024	7	8	9
Jefferson	03/25/2024	13	14	15
Peter	04/01/2024	19	20	21
Susan	04/10/2024	22	23	24
Anderson	04/20/2024	28	29	30
Mary	04/25/2024	28	29	30
Joe	04/30/2024	28	29	30

That is to say, the field “Parameter Date” from Table 2 must be used to define the Parameters to be added to Table 1.

How can I do that?

Thanks for your help.

Maybe I am over simplifying but if that date matches between those two, simply rename the date field in one table to equal the date field in the other. If not, have you try IntervalMatch?

Hello Igor,

The Dates between the tables don't match. There's an interval in table 1 that will match one date in table 2. However, you gave a good tip: Using the IntervalMatch function. I'll try it. 

Thank you, mate.
