## >>> library `dsSQL`: <<< <a name="library-dssql"></a> ########################

The `dsSQL` library stores temporary views 
generated during the `%SQL()` macro execution.

If possible a subdirectory of the `WORK` location is created, like: 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
LIBNAME dsSQL BASE "%sysfunc(pathname(WORK))/dsSQLtmp";
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

if not possible, then redirects to the `WORK` location, like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
LIBNAME dsSQL BASE "%sysfunc(pathname(WORK))"; 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
