SAS 9.3
ODBC engine
I run this code, where the TMP library is an ODBC connection to a case-sensitive SQL Server database:
%kill(lib=tmp,data=apdc_sample_df apdc_sample_hf);
proc copy in=work out=tmp;
select apdc_sample_df apdc_sample_hf;
run;
https://github.com/scottbass/SAS/blob/master/Macro/kill.sas is just a wrapper around PROC DATASETS; DELETE ...
Here is the SAS log for run #1, where the target tables don't exist in the database:
27 %kill(lib=tmp,data=apdc_sample_df apdc_sample_hf);
MPRINT(KILL): proc sql noprint;
MPRINT(KILL): select readonly into :readonly separated by " " from dictionary.libnames where upcase(libname) = "TMP" ;

It is at this point I note that I have the tables tmp.APDC_SAMPLE_DF and tmp.APDC_SAMPLE_HF in my database.
If I wanted capitalized table names, I would have coded it that way. I want the table names as lower case. My downstream code is using explicit passthrough, where the case-sensitivity of the table names matters.
Here is the SAS log for run #2, where the above target tables now exist in the database:

Ok, so that works, although I still have the problem of capitalized table names.
So whatever SAS is doing under the covers:
- PROC DATASETS doesn't detect the lowercase table names, and thus doesn't delete them. It's as though it doesn't implicitly capitalize the table names in the way PROC COPY did? Not that I wanted the capitalized table names in the first place.
- So PROC COPY fails since the ODBC engine doesn't support REPLACEing a table.
I also tried:
%kill(lib=tmp,data=apdc_sample_df apdc_sample_hf);
proc copy in=work out=tmp;
select 'apdc_sample_df'n 'apdc_sample_hf'n;
run;
but no joy.
Why won't SAS just leave my code alone? Is this an issue with the ODBC driver, rather than SAS? SAS and ODBC have been around a long time, why is this still an issue?
I'll eventually find a workaround, but the current functionality is a PITA.
Please post your question as a self-contained data step in the form of "have" (source) and "want" (desired results).
I won't contribute to your post if I can't cut-and-paste your syntactically correct code into SAS.
