Below script is useful when you work with missing index in SQL server database, run below script on database it gives complete info where we have any missing indexes on the database, you need to change database name and values got get full data/fino,
select
*
, 'create index IX_'
+ replace(object_name(object_id, database_id), ' ', '_')
+ '_' + convert(varchar, mig.index_group_handle) + '_' + convert(varchar, mid.index_handle)
+ ' on ' + statement
+ ' (' + isnull (equality_columns,'')
+ case when equality_columns is not null and inequality_columns is not null
then ','
else ''
end
+ isnull (inequality_columns, '')
+ ')'
+ isnull(' include (' + included_columns + ')', '')
as create_index_statement
from

select
