Using While Loop for SQL Server Update

Question

I am trying to become more efficient in my SQL programming. I am trying to run a loop to repeat an update command on field names that only change by a numerical suffix.

Answer 1

while @count < @countOfSession
begin
  if @day = 'Saturday' or @day = 'Tuesday'
  begin
    if @day='Saturday'
    begin
      select @date
      set @day='Tuesday'
      set @count=@count+1
      set @date=@date+3
    end
    else if @day='Tuesday'
    begin
      select @date
      set @day='Saturday'
      set @count=@count+1
      set @date=@date+4
    end
  end
end
