Question

I am using NamedParameterJdbcTemplate for run pl/sql script.
But I don’t know how can I get the values ​​of out variables (:id_out).
Thanks in advance.

String script = "declare 
                   begin 
                     if myFunc(:id_in) is null then 
                        :id_out := 0; 
                     else 
                        :id_out := 1; 
                     end if; 
                   end;";
Map<String,Object> bindVars = new HashMap<String, Object>();
bindVars.put(id_in,1);
bindVars.put(id_out,2);


jdbcTmpl.execute(script, bindVars, new PreparedStatementCallback<Object>() {
    @Override public Object doInPreparedStatement(PreparedStatement cs)
        throws SQLException, DataAccessException {
        cs.execute();
        return null;
                }
       }
       );

I don’t believe you can use a NamedParameterJdbcTemplate (or any other subclass of JdbcTemplate) with anonymous PL/SQL blocks such as that above. You’ll have to wrap your anonymous PL/SQL block into a stored procedure or function.

Spring is intended to be portable across databases. As far as I know, neither MySQL nor SQL Server have a concept analogous to Oracle’s anonymous PL/SQL blocks (I’m happy to be proved wrong on this point, though). Since this feature isn’t portable across databases, Spring can’t really support it for just Oracle.
