Thread: C# .NET OLEDB DataSets

C# .NET OLEDB DataSets Your last visit to this thread was on 1/1/1970 12:00:00 AM

How do I convert a String to Integer......Database date to DateTime?
What's the DateTime value for a DbNull?

Not talking DataReader here, but an OLEDB DataSet.

How do you all handle a 50 column dataset with nulls and datatype conversions? Maybe I should COALESCE each field in the SELECT statement of the OLEDBCommand.TEXT?

Thanks

To convert the datatype of a value there are several different ways to do so:

ie:

int val = Convert.ToInt32(strval);
or
int val = int.Parse(strval);
or
int val = (int)objval;

If you're working with a strongly-typed DataSet you can use the DbType types represented by the values in each DataRow.

Got a specific question?

Well I saw all of the GetInt32, GetSQLString, GetSQLMoney stuff for the data reader, and didn't see the same stuff for a DataSet.

So when I did an
Int32 Val = (Int32)ds[0] (db column was a Long integer)
int val1 = (int)ds[1] (where the db column was a String)
and it blew up I panicked....

Now I've figured out that long means Int64 so I'll play around with this and get back to you.

THANKS!
