Hi All

We are using Firebird 1.0

and in the manual I read the following

"You should recalculate the index selectivity if a change to the table affects the average
distribution of data values"

My question: How should I recalculate the index selectivity ?
and for what values of the statistics should I conclude that the index is not selective enough ?

best regards

Tanno
