Hi,
I am new to Proc Sql and wondering how to use wild cards such as 'SAS%' (SAS*) or 'SAS____ to identify the library names with SAS as prefix in the following code. Same is treu for the MAPS libraries as prefix or SAS as suffix.
Can someone explain these wild cards by showing side by side how they are different from data step.
Appreciated!
data metadata2;
set sashelp.vcolumn;
where libname not in ('SASHELP', "SASHELP", 'SASUSER', 'SAMPSIO',
'SUBFUNC', 'MAPS', 'MAPSSAS', 'MAPSGFK', 'SAL428SL', 'STP:', 'TLV4');
run;
Your use of colon in your initial example wouldn't have worked anyway. Here is a simplified version which, as you can see if you test it, doesn't work:
data metadata2; set sashelp.vcolumn; where libname in ('SAS:'); run;

The same syntax can be used with both. e.g.:
data metadata2; set sashelp.vcolumn; where libname not like ('SAS%') and libname not like ('STP%') and libname not like ('MAPS%') and libname not in ('SAMPSIO','SUBFUNC', 'SAL428SL', 'TLV4'); run; proc sql; create table metadata2 as select * from dictionary.columns where libname not like ('SAS%') and libname not like ('STP%') and libname not like ('MAPS%') and libname not in ('SAMPSIO','SUBFUNC', 'SAL428SL', 'TLV4') ; quit;
