hive：sparksql：針對反斜槓的正則替換問題

hive中如何替換反斜槓： 

 select title from bo.t_positions where title  rlike '\\\\' limit 10

 

替換後：

select regexp_replace(title,'\\\\','/') title from bo.t_positions where title  rlike '\\\\' limit 10

 

sparksql中如何替換反斜槓： 

select position_name,code,senior_name,parent_code,level from position_name_data pnd right join senior_function_data sfd on regexp_replace(sfd.senior_name,'\\\\','/') like  concat('%',regexp_replace(pnd.position_name,'\\\\','/'),'%')  where senior_name is not null group by position_name,code,senior_name,parent_code,level
