I have two tables one having the primary key and another the forign key
the two tables contains data
the primary table already contains data id,name and departmentID ( i added them from stored procedure)
the secondary table gets the data from excel file( I import the excel file to this table succesfuly)
when i made import process some employees in this process does not exsist thats not the problem,
i need to make a filter (or a query) thats select the data that's in primary table but not exsist in secondary table where date =1/2/2011
this is the query but how i can insert where condition where data=1/2/2011
Select pt.*
from Primary_table as pt
left join Secondary_table as st on pt.PK = st.FT
where st.ID is null
