Join and Concat with SQL

Emma — Sat, 16 Nov 2024 03:44:10 GMT

Hi All,

Quick question, I have two tables loaded from an SQL database.

TABLE1:

TABLE2:

My desired output is:

-----------------

TABLE3:

A&B

-----------------------

A & B should be grouped into one single column, please keep in mind that these two tables are coming from an SQL DB and I am currently joining them with a Join().

Thanks

Load both the tables as it is and do this

Table 3:

Load A&B as key,

left join(Table2)

Load * Resident Table1;

If A is the only join key, then do this in three steps - concatenate the A and B values, then join the two on A, and finally drop the A and B values.

LOAD A, B, C, D, A & B as AB
FROM ...

Left Join
LOAD A, D
FROM ...

DROP Fields A, B;

If the join key is more than just A, then you will need to supply more details.
