ADO Recordset

ADO Recordset : To be able to read database data, the data must first be loaded into a recordset.

 ADO 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.
