information about merge statement

[kubo]

dpiStmt_getInfo() returns incorrect information about merge.

I made a test program.
https://gist.github.com/kubo/d8b623072b755edd508896940be86e81
It printed:

SQL: merge info ...
  isQuery: 0
  isPLSQL: 0
  isDDL: 0
  isDML: 0
  statementType: 16
  isReturning: 0

Merge is DML but isDML is zero and statementType is a value not listed here.
In this example the statement is not a valid SQL but it returns same results even for valid statements.

Well, I cannot say that this is a bug due to odpi. That's because OCI_STMT_MERGE is not in OCI manual.
I hope that the Oracle team says 16 is the statement type of merge.

@kubo, thanks for pointing this out. I'll find out and get back to you!

As you can see I have added code to support MERGE statements, as requested. It will get added to the OCI headers and documentation at some point, but it is added to the ODPI-C documentation and headers now. Thanks again for pointing it out!
