group_concat result not work in IN condition

Question

Is there any possible way to put result of group_concat in IN condition of SQL query.

Here in network master table i have comma separated fields in industryId column

Answer 1

you don't need group_concat and IN clause you can use a join

  select i.* 
  from industry_master i
  INNER JOIN network_master  n on  i.industryId = n.industryId 
  AND n.userId =123

group_concat return a string but you need values so using the string in IN clause don't work correctly.

or if can work only an a string you could trying using field_in_set > 0

select * from industry_master 
where find_in_set(industryId,  select group_concat(industryId order by cId SEPARATOR ',') 
      from network_master where userId =123 group by userId)   ;

or
