Re: Difference execution plans for same query

Are the datasets on the two machines identical (or nearly so)? Significant differences in the data, especially for that date range, could easily lead to different explain plans.

Differences in the constants in the query can also lead to different plans. I have seen as many as 6 different plans for the similar queries on the same machine.
