Hi everyone!
Im working with OCI and C language, and I need to convert a values
fetched from a db table in a unix timestamp (seconds passed by january
first 1970).

The table is like this
create table  test(.... ts timestamp not null...);

and the code to define the output variable (for a select statement) is
the following, where time is an OCIDateTime variable

OCIDefineByPos(stmth, &defineh, errh, pos, (dvoid *) time, 0, SQLT_ODT,
              (dvoid *) 0, (ub2 *) 0, (ub2 *) 0, OCI_DEFAULT);

once I have initialized "time", how can I convert his content to unix
And viceversa, how can I put an int value rapresenting a unix timestamp
in an OCIDateTime variable, and then insert it correctly inside mt
thank you!
