一个参数传两次，占位符名称相同，参数要怎么设呢？

Sql sql = Sqls.create("select IFNULL(MAX(x.id)+1,@placeId*1000+1) from tm_term x where x.id like '@placeId%' ");
sql.params().set("placeId", placeId).set("placeId", placeId);

org.nutz.dao.DaoException: !Nutz SQL Error: 'select IFNULL(MAX(x.id)+1,350104000001*1000+1) from tm_term x where x.id like '350104000001%''
PreparedStatement: 
'select IFNULL(MAX(x.id)+1,?*1000+1) from tm_term x where x.id like '?%''
