ADO Recordset
To be able to read database data, the data must first be loaded
into a
recordset.
Create an ADO Table Recordset
After an ADO Database Connection has been created, as demonstrated in the
previous chapter, it is possible to create an ADO Recordset.
Suppose we have a database named "Northwind", we can get access to the
"Customers" table inside the database with
the following lines:
<%
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 "Customers", conn
%>
|
Create an ADO SQL Recordset
We can also get access to the data in the "Customers" table using
SQL:
<%
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 Customers", conn
%>
|
Extract Data from the Recordset
After a recordset is opened, we can extract data from recordset.
Suppose we have a database named "Northwind", we can get access to the
"Customers" table inside the database with
the following lines:
<%
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 Customers", conn
for each x in rs.fields
response.write(x.name)
response.write(" = ")
response.write(x.value)
next
%>

The ADO Recordset Object
The ADO Recordset object is used to hold a set of records from a database table.
