ResultSet使用jdbcTemplate中的查询参数

Question

没有在docs中找到.

java ResultSet是否支持查询参数,例如jdbcTemplate？

例如,类似于:

int length = 10;
ResultSet rs = stmt.executeQuery("select MyTable.COLOR from MyTable where MyTable.LENGTH = ?", new Object[] { length });

可能吗？

谢谢.

Answer 1

PreparedStatement 允许(编号)参数:

PreparedStatement pstmt = connection.prepareStatement(
      "select MyTable.COLOR from MyTable where MyTable.LENGTH=?");

pstmt.setInt(1, desiredLength);

ResultSet rs = pstmt.executeQuery();
