Home -> Community -> Mailing Lists -> Oracle-L -> RE: imported database inconsistencies
OK I was just able to bounce our test instance, and found that changing the
optimizer mode made the difference. The RBO uses an index, the CBO opts for
a full table scan(Only 300 rows in the table). The trouble is that some of
the values in RV_LOW_VALUE are not numeric. The FTS is evaluating the
RV_LOW_VALUE attribute for each returned row, and well causing the numeric
value error.
Interestingly enough I rewrote the original query to place the RV_DOMAIN condition earlier in the Where clause(before the to_char(RV_LOW_VALUE) condition), and the problem disappears. I guess the order of the where clause can make a difference.
