---------------------------------
Hi Knut:
I notice different in "Number of opens" and "Rows input". Please see
below. Will these two numbers cause the instability? Will the number be exactly
the same since the data is the same? What do you think?
=============
Expected-plan.txt
....
Source result set:
...
Number of opens = 2
Rows input = 2068
...
Index Key Optimization = false
..
Number of opens = 2
Rows seen = 2068
...
Plan.txt
...
Source result set:
...
Number of opens = 12
Rows input = 11375
...
Index Key Optimization = false
..
Number of opens =1 2
Rows seen = 11375
