sql - Cannot update the view or function 'cte' because it contains aggregates, or a DISTINCT or GROUP BY clause, or PIVOT or UNPIVOT operator -

-

i want delete using having .

so try execute following statement :

;with cte (  select  emp_num, [from_date],[to_date],[ req_ser], [ req_year]  empmission group emp_num, [from_date],[to_date],[ req_ser], [ req_year] having count(*) >2 )  delete     cte

but following exception :

cannot update view or function 'cte' because contains aggregates, or distinct or group clause, or pivot or unpivot operator.

use window functions:

with todelete (       select em.*,              row_number() on (partition emp_num, [from_date],[to_date],[ req_ser], [ req_year]                                 order (select null)) cnt       empmission em )  delete todelete cnt > 2;

note deletes all rows duplicate values. often, want keep 1 of values. if case, ask question.
