Subject: SQL list column from multiple records on one line
I found this 9-year old article
https://www.mcpressonline.com/programming/sql/techtip-combining-multiple-row
-values-into-a-single-row-with-sql-in-db2-for-i but I'm wondering whether
SQL has been enhanced so that there's an easier (more intuitive) way to do
this.
