This question may be miss comprehended, what I have done is created a column with a column view (not a full table view).
For example:
SELECT SQL_CALC_FOUND_ROWS <Field1>, <Field2>, <Field3>, Hour(TIMEDIFF(<Field2>, <Field3>)) as <Field4> FROM <TableName>
The fourth field ( <Field4>
) with the time diff does not get sent to the database.
Now what I want to do is use the sum formula on <Field4>
, but I am unsure on how to do this without it being saved to the database.
Any Ideas?
EDIT:
SELECT SQL_CALC_FOUND_ROWS Date, Start, Finish, Hour(TIMEDIFF(Start, Finish)) as HoursTest FROM Hours
Here is my actual select statement.
If I understand the question correctly, I think you want to save the select statement as a view, then do the sum from the view.
so
create view mynewviewname as
SELECT SQL_CALC_FOUND_ROWS , , , Hour(TIMEDIFF(, )) as FROM
then
SELECT sum(field4) from mynewviewname where (whatever you want to query by)
Does that help?
