ADO Precision Attribute
Definition and Usage
The Precision attribute can be set or returned as a byte value, which represents the maximum number of digits allowed when representing the value of a Parameter or Field object.
Syntax
objectname.Precision
| Object | Description of Precision attribute |
|---|---|
| Field |
For the Field object, Precision is typically read-only. However, for a new Field object added to the Fields collection of the Record, Precision is read/write only when the Field's Value attribute is specified and the data provider successfully adds the new Field by calling the Update method of the Fields collection. |
| Parameter | For the Parameter object, the Precision property has read/write access. |
Example
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"
set rs = Server.CreateObject("ADODB.Recordset")
rs.open "Select * from orders", conn
response.write(rs.Fields(0).Precision)
rs.Close
conn.close
%>
