1. What are the limitations of proc sql explicit pass through?
2. How to increase the memory size for current SAS session part from the option 'Memsize'? e.g. I want to generate the billion of records with numerous variables in WORK library without any memory issue.
You cannot change the memsize for a running session. Memsize (and other memory-related parameters) is set at SAS invocation only (from commandline or config file).
IMO memsize will not be a factor for SQL and SQL pass-through. Disk space in the WORK may be the limiting factor.
May I request you to elaborate your answers simple terms? Because I couldn't understand 'IMO memsize will not be a factor for SQL and SQL pass-through. Disk space in the WORK may be the limiting factor'
The result back will be a sequential write, which is not a memory intense operation. Test yourself by specifying
options fullstimer;
and run your SQL.
