what are the methods that you would employ to fine tune
your SQL extract process using SAS/Access or Proc SQL?

Answer Posted / sastechies

Some answers that I know...

1.Remote Pass thru SQL (RSPT) using Proc SQL is the best
method to extract data from other DBMS.
2. Use the available INDEX on the table / SAS datasets.
3. Improvise on the WHERE expression to pull data that you
would only require...
4. When using SAS/Access use a high value for DBCOMMIT=
option (default is 1000 rows)
5. If someone is trying to extract data and then do certain
transformations and then loading back the data to the same
external database...then the best thing is to use RSPT and
write Native SQL statement using the EXECUTE Statements.
