explain

[Ricardo Conrado Serafim]

Hi group,

Someone can answer me if when I execute the "explain" in a select 
statement, the select is executed to get the parameters or this 
information came from other place? In other words, the explain covers 
the table and indexes or it calculate based on numbers of rows, etc.

regards
