I need to fill up the Table using cursor where
cursor should fetch data from
Declare Cur_AREA Cursor
For
Select Distinct Media From DIM_AREA
Note:DIM_AREA CONSISTS OF texas,dallas,chicago and newark.
Cursor should fill data for years 1990 to 2020
My cursor code is::
Declare #Temp_Year int
Select #Temp_Year = MAX(Year)
While #Temp_Year < DATEPART(YEAR, GETDATE())
Begin
Declare Cur_Media Cursor
For
Select Distinct Media From DIM_AREA
Order by Media
open Cur_Media
Fetch Next From Cur_Media
While ##FETCH_STATUS = 0
Begin
Declare #Temp_Month int
Set #Temp_Month = 1
While #Temp_Month <= 12
Begin
Insert into Table_A (Media, Year, month)
Set #Temp_Month = #Temp_Month + 1
Set #Temp_Year = #Temp_Year + 1
end
end
Close Cur_Media
Deallocate Cur_Media
But my cursor not working properly :(

You may have other problems here, I don't think your question is fleshed out, but you say:
Insert into Table_A (Media, Year, month)
But you don't pick anything to be inserted.
Use:
Insert into Table_A (Media, Year, month)
VALUES('','','')
or:
Insert into Table_A (Media, Year, month)
SELECT '','',''
FROM YourTable
Replacing the empty quotes with whatever you are trying to insert.
