Subj:   Expression Statistics
 
From:   Kavitha_Appou

Hi Forum,

Can anyone tell me what exactly Teradata does in expression statistics when we collect stats on an expression?

On what scenarios we have to collect expression statistics? Is it that for all expressions in filters and Join conditions, we have to collect expression statistics?


Thanks,

Kavitha.
