hi Teradata forumers,
Can you guys help figure an SQL? here's my problem. For my query tuning work, Im joining a fairly big table and a small one.The column being joined in the BIG table is only a NUSI, the smaller table is using a NUPI. As I know, NUSI cant have distribution of data so Im proposing to change the structure of the BIG table to use the column as PI buy, i was advised not to since the table is huge and will impact a lot of users. Now, replicating the big table aint an option since spool and temp space is limited. A JI can help but the inserts can be slower and might hamper the overall performance/timing. Any ideas guys? What could i use in order to have a good join condition?
