Answer: There are a few ways to verify whether a table exists within Oracle. One way is to describe it to check if the table exists: SQL> desc mytable. Another is to select the first row to check that the table exists (hey it may have millions of rows!): SQL> select * from mytable where rownum=1; At bare minimum, you will get a response of 0 rows selected which means the table exists, but there is no data in the table. You can also check the data dictionary to see if a table exists: SQL> select table_name from user_tables where table_name='MYTABLE';
If so then SAS will have already converted the invalid dates that you have in your date variable in Oracle into missing values. You will not be able to tell the difference between a value that Oracle considers null and one in that strange date format with zeros both will stored as SAS missing values. libname mylib oracle .... ; proc sql ;
