Question

I’d like to run a query on a table where I concatenate the the value of one column with another.

Something like the following (javascripty attempt):

UPDATE table
SET items = items+","+item1
WHERE item1 != "No Data" || item1 != "";

Is this possible to do in the database or do I need to be doing it in the middleware?
Any pointers again much appreciated.

Take a look at concat_ws:

# Untested, but should work
UPDATE table
SET items = CONCAT_WS(',', items, item1)
WHERE item1 != "No Data" || item1 != "";
