Dear Experts,
I have a table with many advanced [around more than 400] empty paritions on DATE_fld column. But when i give the condition 'DATE_fld >DATE'
[current date], its obvious it will scan all post partitions after the date given. [My PPI is on DAY basis]
But is there any performance issues when the query scans a lots of empty partitions ?
I know that it might sometimes will mislead for making suboptimal plan choices. But still want other thoughts...
