Hur anropar man Oracle-funktion eller lagrad procedur med fjäderbeständighet?

Förutsatt att du syftar på JdbcTemplate:

jdbcTemplate.execute(
    new CallableStatementCreator() {
        public CallableStatement createCallableStatement(Connection con) throws SQLException{
            CallableStatement cs = con.prepareCall("{call MY_STORED_PROCEDURE(?, ?, ?)}");
            cs.setInt(1, ...); // first argument
            cs.setInt(2, ...); // second argument
            cs.setInt(3, ...); // third argument
            return cs;
        }
    },
    new CallableStatementCallback() {
        public Object doInCallableStatement(CallableStatement cs) throws SQLException{
            cs.execute();
            return null; // Whatever is returned here is returned from the jdbcTemplate.execute method
        }
    }
);

Att anropa en funktion är nästan identiskt:

jdbcTemplate.execute(
    new CallableStatementCreator() {
        public CallableStatement createCallableStatement(Connection con) {
            CallableStatement cs = con.prepareCall("{? = call MY_FUNCTION(?, ?, ?)}");
            cs.registerOutParameter(1, Types.INTEGER); // or whatever type your function returns.
            // Set your arguments
            cs.setInt(2, ...); // first argument
            cs.setInt(3, ...); // second argument
            cs.setInt(4, ...); // third argument
            return cs;
        }
    },
    new CallableStatementCallback {
        public Object doInCallableStatement(CallableStatement cs) {
            cs.execute();
            int result = cs.getInt(1);
            return result; // Whatever is returned here is returned from the jdbcTemplate.execute method
        }
    }
);
