HI All,

i have a table which needs to store values like -562,000.00 in one of its columns. i have declared the field type to be numeric(18,2) for that column. I am trying to update that columns using a Stored Procedure but wheni add parameters to the command object from code as

C#

comm1.Parameters.Add("@Excl", SqlDbType.Decimal).Value = Convert.ToDecimal(objDataSet.Tables[0].Rows[i]["Excl"]);

I am getting an error.

What is the Datatype i should be using here?

Thanks.

Input string is not in correct format.
it happens when the Convert.ToDecimal( is happening.

Use single it will work

comm1.Parameters.Add("@Excl",  SqlDbType.Decimal).Value = Convert.Single(objDataSet.Tables[0].Rows[i]["Excl"]);

or

comm1.Parameters.Add("@Excl",  SqlDbType.Float).Value = Convert.Single(objDataSet.Tables[0].Rows[i]["Excl"]);
