Are you looking for an ODBC sample program for querying and updating a large binary object (LOB) against a TimesTen database?
Look no more. A new ODBC sample program called updatelob.c is available in the quickstart packet under the oracle-timesten-samples respository on github. The update program queries against a Large Binary Object (LOB) field and then updates the selected LOB field with the new value of the same row. Before executing this program, you need to provision the PRINT_MEDIA table.
This sample program is part of the quickstart classic odbc sample programs under oracle-timesten-samples. Access to it and other quickstart sample programs are available via oracle-timesten-sample quickstart repository.
