Hibernate Stored Procedure with first parameter not "OUT"

I spent some days trying to call a Stored Procedure through Hibernate. I used CreateSQLQuery  and I made my own custom transformer, but I could not get it work. I keep geeting Wrong Type and Parameter of procedure exception.

My procedure was like the following

    procedure GET_BY_EMPLOYEE (
      , P_DATE_FROM  in       date
      , P_DATE_TO    in       date
      , P_REF           out      CURSORREFERENCETYPE);

After days of searching, I found this

For Oracle the following rules apply:

  • A function must return a result set. The first parameter of a procedure must be an OUT that returns a result set. This is done by using a SYS_REFCURSOR type in Oracle 9 or 10. In Oracle you need to define aREF CURSOR type. See Oracle literature for further information.

So there is no way to get this procedure to work in hibernate. I will use a plain JDBCTemplate.

Building bitcoin/litecoin on mac os x missing EC.h

For my own fun, I was playing around with bitcoin, to check how the parameters of the cryptocurrencies can be modified.

After recent upgrades to my OS, I could not build any longer the bitcoind. Seems like something changed on that side. Now this command

./configure --with-gui=qt5 --enable-debug
Was sistematically producing 
configure: error: OpenSSL ec header missing

EC is the file for elliptic curve cryptography. I had brew correctly configured, and the header files were all correctly present. After some time spent inspecting the issue, on github I was able to find the solution for this problem. I simply add to export the following
export LDFLAGS=-L/usr/local/opt/openssl/libexport CPPFLAGS=-I/usr/local/opt/openssl/include
There is aksi pull request on bitcoin for that, I hope I could save you some time
