To be able to read database data, the data must first be loaded into a 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 %> |
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 %> |
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 is used to hold a set of records from a database table.
