In my vb.net code, I had the following code:

Code:
 sql = "INSERT INTO Trn_BranchReportTop ([SellerID],[BranchGLN],[BranchName],[Total]) VALUES('" + Session.Item("UserCompanyID") + "','" + BranchGLN + "','" + Name + "','" + dsPOTrailers.Tables(0).Rows(0).Item("Cost").ToString() + "' )) "
                    objDB.ExecuteNonQuery(sql)
How should I change so that the dsPOTrailers.Tables(0).Rows(0).Item("Cost").ToString() can be insert to the database which is double datatype in the database.
