Question

I have the following piece of sql query:

Sql += " SELECT     ISNULL(SUM(COALESCE (a.currency, 0)), 0) AS monthCurrency              
FROM          IW_Awards AS a ";

The query works fine, I am trying to cast this value in C# after the query has been submitted and I cannot find what type it is.

I tried int, int? and string. When I tried to cast to a string I had the following error message:
Unable to cast object of type ‘System.Decimal’ to type ‘System.String’.

And when I tried to cast it to an Int or Int? I got:
Specified cast is not valid.

Database: SQL
IDE: Visual Studio 2010
Database interface: LINQ (but I am creating my own query)
Server side language: C#

Thank you for your help.

Answer 1

Did you try decimal? It told you it was trying to cast a System.Decimal to a string when you tried to cast it to a string.

It will return whichever type Currency is.
