[CLOSED]JOIN where records don't exist
I am joining a table of metrics for a list of personnel. If the person does not exist in the metrics table, I need to assign a standardized metric without hardcoding. I have a standardized line in my metrics table labeled "STAND". How do would I join to the "STAND" if the person does not exist?

Hi Maggie,

There are several ways.

One way would to make 2 joins, an (outer) join on the person metrics and another join to the STAND metrics. Then make defines for the metric attributes you need like METRIC1 = IF person.METRIC1 IS MISSING THEN stand.METRIC1 ELSE person.METRIC1;

The second join is however always to the same one record, so for performance reasons it seems better to first fetch only that record and place the required metrics in amper variables (HOLD en -READFILE). Again you would need the defines as above, but replace the stand.METRIC1 by the amper variables.

I hope this gets you on the way.

Martin.

Hi Maggie and welcome to the WF forum!
You don't say what type of table holds your metrics neither from where are you joining.
What do you mean by "without hardcoding"?
