You can use the SAS system option SASTRACE to see where your SAS code is being processed when using implicit pass-through (with the libname statement vs. explicit pass-through syntax) to query a relational database. PC users must also use SASTRACELOC with SASTRACE to show trace results in the log. Even if your SAS code is not written using Proc SQL, SAS will still try to translate some of it and pass it through to the native database for processing.
The following statement with SASTRACE set to ‘,,,d’ ensures that SQL SELECT, INSERT, UPDATE, CREATE, DROP, and DELETE statements sent to the Microsoft Jet engine are identified and printed to the log:
OPTIONS SASTRACE=’,,,d’ SASTRACELOC=SASLOG NOSTSUFFIX;
