Problembeschreibung: | |
You might encounter a trap when a compiling an SQL statement that satisfies the following conditions: 1. the statement qualifies the starjoin eligibility criteria, and 2. one or more tables participating in the starjoin apply subquery predicates, and 3. an optimization guideline is applied to the statement In a trap file, you might see the stack traces as following: ... sqlno_crule_nljn sqlno_crule_join_choices sqlno_crule_join_order sqlno_crule_join_root sqlno_crule_join sqlno_starjn ... Following is an example of a query that satisfies conditions 1 and 2, assuming F is identified as the fact table of the star join, and D1 and D2 are the dimension tables: select F.D1, F.D2, F.D3, F.D4, M, substr(D1.C,1,4) from F, D1, D2 where F.D1=D1.key AND D1.attr<80 AND D1.keya<40 AND F.D2=D2.key AND D2.attr<80 AND D1.Y not in (select Y from D3 where Y > 10 order by Y); | |
