Subj:   Re: Creating PPI table
 
From:   Christian Schiefer, makeITdone

Hi,

I think you cannot compare the performance of a "sel count(*)" with the "insert into select ". Especially if you have defined an index on the column Event_Value_Date. In this case the count(*) is only accessing the SI and not the physical table to count the number of records.


Greetings

Christian
