Proc SQL Explicit pass through and Memsize

[RamKumar]

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.

[Kurt_Bremser]

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.

[RamKumar]

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.
