Pentaho 表输入中的参数整数

我有一份工作和两次转变。 在第一次转换中，我有表输入，从表中获取max（id）。 接下来，我将行复制到结果->写入日志->设置变量。 在集合变量中，我有字段名=max\u id和变量名=max\u id

在第二次转换中，我得到了名为max_id、变量为${max_id}、类型为Integer->Write to log的变量

接下来是表输入=

   select id AS CCOLUMNS from REPO.dbo.STATUS with (nolock)
   where id = ${max_id}

我进入日志：

当您通过在“从步骤插入数据”中指定步骤，将表输入步骤配置为使用来自流的传入字段时，就会发生这种情况。当您使用命名变量（和变量替换）时，不需要这样做

手动清除该步骤的名称，就可以开始了
