I'm attempting to do an OUTER JOIN of two tables
neicstats (6841 rows)
customer (5062 rows)
I'm using the command
select * from neicstats left outer join customer on (
neicstats.cli_num = customer.cust_no );
which seems to run forever.
I've created indexes on both cli_num and cust_no but 'explain' seems
to indicate they're not being used -
explain select * from neicstats left outer join customer on (
neicstats.cli_num = customer.cust_no );
NOTICE: QUERY PLAN:
Nested Loop (cost=0.00..2297525.72 rows=285698 width=532)
-> Seq Scan on neicstats (cost=0.00..206.87 rows=6687 width=140)
-> Seq Scan on customer (cost=0.00..267.62 rows=5062 width=392)
What methods can I use to speed up this query? Why does it take so
long?
