I'm not sure if this is what you are looking for, but this combines table1 and table2's results based on matching the EID and it lets you provide multiple EIDs.

select * from table1,table2
where (table1.eid = 100
or table1.eid = 103
or table1.eid = 104
or table1.eid = 117
or table1.eid = 119
or table1.eid = 122)
and table1.eid = table2.eid
