Need to find table size in SAS EG

BarryP — Wed, 05 Feb 2020 20:36:18 GMT

Hi all,

I searched the forum and found a solution, but I don't understand what any of the commands mean so I'm unable to modify it to get it to do what I need.

proc sql;
 select memname, filesize format=sizekmg10.1
   from dictionary.tables
   where libname='SASHELP' and memtype='DATA';
quit;

This solution gives me a list of random tables I don't recognize and does not include any of the tables that I need to know the sizes of.

Thanks!

Hi @BarryP Do you mean to say you want to query tables sizes in the library that is of your interest and not SASHELP?

If yes, wouldn't you be stating the libname of your interest i.e

where libname='YOUR_LIBNAME' and memtype='DATA';

Basically, Dictionary tables is akin to metadata(data about data) that contains information about various libraries, tables, columns, etc etc. In other words Dictionaries are data definitions. Therefore the need for you is perhaps query the library(schema) of your interest

Would I insert the libname statement in place of YouR_Libmname? I assume?

Okay,

I can do this with basic Libnames, like SASHELP and WORK but other's are not working. Specifically a name like, 'HEARTDS - DI Work (ABXY_HEARTDS_0_1_0_0_0_0_0_0)' is not returning any results.

You will need to identify the correct library reference name for the query to work. A library reference is name that has a maximum of 8 bytes with 1 char=1 byte. The name can begin only with a letter or an underscore followed by numbers or chars
