We have a SQL agent job tied to an SSIS package that process does an Update process on the dimensions and a full process on the Facts. In the morning the cube is showing that it is processed but the new data is not present. When it is manually run the SSIS package, it seems to work fine. Basically there is job having two steps, one is to update the BI Cube and next step is to update dimensions and facts. This jobs runs perfectly without any error, but first step executes as per the expectation and second fails to update with latest data. If we try to manually run the SSIS Package of the second step it perfectly updates with the latest data.

View 2 RepliesI have a problem, I need to get a date from an SQL database using a dataset.xsd.
To do that, I have created a query in the TableAdapter called GetDataByFecha:
SELECT fecha
FROM T_Tickets
WHERE(fecha = @fecha)
in C# I do this:
DateTime T_fecha;
T_fecha = Convert.ToDateTime(ticketsAdapter.GetDataByFecha(fechaTicket));
but, when I compile it I get this error:
cannot convert a 'T_TicketsDataTable' object to 'System.IConvertible' type.

}

View 7 RepliesI'm trying to remove extraneous characters like quotes, commas, etc from my dataset. I get the fact in the standard way of doing things in your code behind you simply go
string data = data.replace(",",""); or something like this. However, a datasource doesn't seem to give me that capability. What can I do to make it do this? I'm importing data from an excel sheet into a gridview. The commas are goofing up my view. I'd like to replace any commas in the dataset with spaces. Here is the code I have.

I'm fairly new to asp.net and I'm trying get my arms around the data entry and update. I have created a nice data entry formusing a stored procedure. It works well but for a test database, it's pretty much overkill, but worthwell in learning how. I'm going through the ADO.NET quick start tutorial and I've ran across a couple of questions that I've not be able to answer. In my website,I'm wanting to edit the database by creating a separate form that is filled with the existing database information for that particular id. My main question is how to I take the information from the dataset and get it into my form. The code below is not fillingmy form. Not sure what I should be using here:
