Hi Allen, which "performance issue" are your referring to? Stefan On Sun, Aug 09, 2009 at 05:13:54PM -0700, Allen Zhang wrote:
Hi, All,
I have a client program generates the following query against monetdb, can I create index on fact columns to speed thing up? What¹s the best approach to resolve this kind performance issue?
SELECT DISTINCT t1.column1 FROM (fact t0 LEFT JOIN dimension1 t1 ON t0.header_id = t1.header_id) WHERE t0.column3 = 'xxxxxx' And t0.column5 IN ('item1¹, OEitem2¹, OEitem3¹, OEitem4¹);
Thanks in advance. Allen
