Sashelp library- issue reading data

Abdulla1 — Mon, 07 Feb 2022 19:05:39 GMT

Hello

I've used code1 below to check all the variables names in different libraries it worked flawlessly, however when I used it to read from the Sashelp library it keeps giving me an empty table. it seems that sas is not reading the library in this code specifically, however, if I tried to print the data in one of sashelp files (per code2 below) it reads it and show me the result. may you help me understanding my mistake in code1

code1

__________________________

proc sql;
create table mTable as
select * from dictionary.columns
where libname = 'sashelp'

and memname ='filename' ;
quit;
_________________________

code2

_________________________

proc print data=sashelp.Cars;

run;

Correction

Code1 is

proc sql;
create table mTable as
select * from dictionary.columns
where libname = 'sashelp'
;
quit;

where libname = 'sashelp'

should be

where libname = 'SASHELP'

the capital letters make a difference.

Also this won't work:

and memname ='filename' ;

because there are no memnames (which are data set names) that have the name 'filename' or 'FILENAME'. So its not clear to me what you are doing. What are you trying to do?

thanks @PaigeMiller

I spent over 3 hour on that but didn't thought about changing them to capital letters!.

the filename part was written as a comment in my original file coping it was a mistake.

Suggestion: LOOK AT the dictionary table with your own eyes

proc sql;
    select distinct(libname) from dictionary.columns;
quit;

or look at table SASHELP.VCOLUMN, it is dictionary table.
