Hello,
we got a bit of an unstable Oracle DB environment and I wonder if there is a way to check if table A & B is available
before I run my proc sql to select from them.
Bye
Why not you create a temporary odbc library for your oracle DB in SAS EG or Base SAS, and check that two tables are presence or not in that database.
You could select from dictionaries.tables as pass through, this would return what tables are available, something like:
proc sql; connect to oracle (path=...); create table O_DATA as select * from connection to oracle ( select * from DICTIONARY.TABLES where NAME="<yourtable>"); disconnect from oracle; quit; data _null_; set o_data; call execute('proc sql; ... quit;'); run;
So pull the metadata from oracle where the name is your table (note you will need to update specifics), then in a datastep generate the proc sql to extract data only if a row for your dataset is returned, i.e. the above will return no obs if your table doesn't exist, hence will not generate the call execute.
This explicit passthrough is a good idea. You'll need to query from all_tables - Oracle's idea of dictionary.tables.
