Why this SQL executes in MySQL and not through Eclipse?
===

I have the following table in MYSQL:

      CREATE TABLE 't001_prospeccao' (
      'pro_id' bigint(20) NOT NULL AUTO_INCREMENT,
      'pro_cliente' bigint(20) NOT NULL,
      'pro_produto' bigint(20) NOT NULL,
      'pro_status' int(11) DEFAULT NULL,
      'pro_vlr_entabulado' double DEFAULT NULL,
      'pro_vlr_contratado' double DEFAULT NULL,
      'pro_vlr_utilizado' double DEFAULT NULL,
      'pro_obs' varchar(255) DEFAULT NULL,
      'pro_dt_visita' datetime DEFAULT NULL,
      'pro_dt_originacao' datetime DEFAULT NULL,
      'pro_protocolo' double DEFAULT NULL,
      'pro_correio' double DEFAULT NULL,
      'pro_dt_status' datetime DEFAULT NULL,
      'pro_funci' bigint(20) DEFAULT NULL,
      PRIMARY KEY ('pro_id'),
      UNIQUE KEY 'id_UNIQUE' ('pro_id')
    ) ENGINE=InnoDB AUTO_INCREMENT=13 DEFAULT CHARSET=latin1

And the following INSERT statement, which executes normally in MySQL console:

    INSERT INTO t001_prospeccao (pro_cliente,pro_produto) VALUES (123456789,111)

But, on running this code in Eclipse, an error occours:


     String sql = "INSERT INTO t001_prospeccao (pro_cliente,pro_produto) VALUES (?,?);";
    
    			PreparedStatement stmt = connection.prepareStatement(sql);
    
    			try {
    				stmt.setLong(1, p.getCliente().getMci());
    				stmt.setLong(2, p.getProduto().getCod());
    				
    				stmt.execute(sql);
    				
    			} catch (SQLException e) {
    				throw new RuntimeException(e);
    			} finally {
    				stmt.close();
    			}

Error:

    You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?,?)' at line 1

Data from stmt object:

    INSERT INTO t001_prospeccao (pro_cliente,pro_produto) VALUES (123456789,111)

What should I doing wrong? Thanks in advance.
