childewuque opened a new issue #2250: 分表的字段支持负数吗？
URL: https://github.com/apache/incubator-shardingsphere/issues/2250
 
 
   如果业务上unit_id是包含负数和正数，当unit_id是负数时，下面的配置，得到的表名可能是l_unit_-1，请问该如何正确配置呢？ 
   
   yaml关键配置:
   ....
   tables:
           l_unit:
             actual-data-nodes: ms.l_unit_$->{0..1}
             key-generator:
               column: id
               type: SNOWFLAKE
             table-strategy:
               inline:
                sharding-column: unit_id
                algorithm-expression: l_unit_$->{unit_id % 2}
