The maximum number of digits used to represent the Value property. The default value is 0, which indicates that the data provider sets the precision for Value.

Examples
The following example creates an OdbcParameter and sets some of its properties.
Public Sub CreateOdbcParameter()
Dim parameter As New OdbcParameter("Price", OdbcType.Decimal)
parameter.Value = 3.1416
parameter.Precision = 8
parameter.Scale = 4
End Sub
public void CreateOdbcParameter()
{
OdbcParameter parameter = new OdbcParameter("Price", OdbcType.Decimal);
parameter.Value = 3.1416;
parameter.Precision = 8;
parameter.Scale = 4;
}
Remarks
Setting this property to a value other than the value in the database depends on the implementation of the data provider and may return an error code, truncate, or round data.
The Precision property only affects parameters whose OdbcType is Decimal or Numeric. For other data types, Precision is ignored.
Note
Use of this property to coerce data passed to the database is not supported. To round, truncate, or otherwise coerce data before passing it to the database, use the Math class that is part of the System namespace prior to assigning a value to the parameter's Value property.
