Best way to calculated column in DB or SSRS
reporting-services, sql-server-2008, ssrs-2008, t-sql
Solution
Basically, it depends.
- If the calculated value is fairly static then this favours a persisted computed column.
- If the calculated value is useful in multiple reports, then this favours the computed column
- If the report server and the reporting database are on the same SQL Server it may be a wash in terms of load,
- If the report db is on an OLTP server but the report server is on a different instance it favour the the tablix to move the load.
- There may also be a consideration for the nature of the calculation itself. Some may be more natural for one or the other.
I'm probably missing some, but the point is I don't believe that there is single right answer to the question.
Problem
When we have some calculated column in database for reports, which is best way to calculated it's value in case of SSRS report development. - Calculate it in SSRS tablix - Calculate it from database and return as dataset If I am duplicating this question then sorry for that, but I didn't got proper answer while googling.
