[sqr-users] Nested SQL performance question

Hi,

            Does anyone know how SQR processes two nested begin-select
statements?  Does the Portal server run the outmost query to completion
(storing the results on the Portal server) and then call the nested
procedure for each row in the outermost query's result set?  Or does the
Portal open two cursors to the database at the same time and call the
innermost select for each row returned in the outermost select?  Any
ideas?

 

Thanks Tom
