Hi,
Please, I would like to know the correct sintaxis for calling a stored
procedures in MonetDB from a Java application. I was using some code that
works fine in MySQL but this doesn't work in MonetDB. The code inside a
method is:
-------------------------------------------------------------------
Connection con = null;
ResultSet rs = null;
CallableStatement cs = null;
cs = con.prepareCall("{call hts.spInsertFile(?)}");
File fl = new File("/home//Test/example.pdf");
imgfile = new FileInputStream(fl);
cs.setBinaryStream(1,imgfile);
rs = cs.executeQuery();
-------------------------------------------------------------------
When I execute the stored procedure from Netbeans IDE the stored procedure
works fine. I've made a trace in the application and the statement:
con.prepareCall("{call hts.spInsertFile(?)}"); returns null and finally
throws an exception:
Exception in thread "main" java.lang.NullPointerException
at testmonetdb.DBase.set_file(DBase.java:86)
at testmonetdb.MonetDBTest.main(MonetDBTest.java:34)
The MonetDB version I'm using is:
