sys.dm_exec_sql_text not showing all queries

 i am using sys.dm_exec_sql_text DMV to get the  Query on a Particular Database.But this DMV is not showing every Query.

Example:

if i run the Query ----> select * from Employee ---------- this Query is visable in this DMV

but if i Run this Query(select * from Employee where Empid=100)  this query is not showing in this DMV.

help me to find every query.
