mysql使用UnionAll和PartitionBy，会报错 返回

Table 'expandoobject' doesn't exist

但是运行生成的sql，会报group by的错误

1055 - Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'unionTable.Title' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

在文档中这样写道：

并且即使不写Take(1)，也会默认生成 LIMIT 0,1
