Notes
For situations where you need to set a database column to NULL, you should use the Value property like this:
rs.EditRow
rs.Column("MyDoubleColumn").Value = Nil // sets to NULL in the database
rs.SaveRow
rs.Column("MyDoubleColumn").Value = Nil // sets to NULL in the database
rs.SaveRow
Sample Code
Get the double value of a column in a RowSet:
// rs is a RowSet with a double column called "InterestRate"
Var interestRate As Double
interestRate = rs.Column("InterestRate").DoubleValue
Var interestRate As Double
interestRate = rs.Column("InterestRate").DoubleValue
Set the double value of a column in a RowSet:
// rs is a RowSet with a double column called "InterestRate":
rs.EditRow
rs.Column("InterestRate").DoubleValue = 3.625
rs.SaveRow
rs.EditRow
rs.Column("InterestRate").DoubleValue = 3.625
rs.SaveRow
