Subj:   Re: Parsing of SQL and macro efficiency
 
From:   Carpenter, John



This depends entirely on the SQL statement involved. If there are embedded comparison values then it will not be cached right away. Only if it is seen again with the same values. Whereas a Macro with parameter values will be immediately cached by the parsing engine and be ready for reuse.
