This article demonstrates how to call an Oracle package to retrieve a recordset using ADO on Active Server Pages (ASP).

This article assumes that:
  • You are proficient with Visual Basic Scripting Edition (VBScript), ActiveX Data Objects (ADO), and Active Server Pages (ASP).
  • You understand Oracle's Procedural Language/Structured Query Language, if you will also be creating Oracle packages.
  • Your Internet Information Server (IIS) is configured properly to the Oracle database.

More information

To call an Oracle stored procedure, the stored procedure must be encapsulated within a package. The following sample uses an Oracle package that was assembled as an example in the Microsoft Knowledge Base article below:
174981 How To Retrieve Typical Resultsets from Oracle Stored Procedures
The script sample below does not use a Data Source Name (DSN) to connect to Oracle. It uses a DSN-less connection. (You can use a system DSN by commenting out the appropriate lines.) The sample uses ODBC to connect to Oracle.

Note that you could also use the Microsoft OLE DB Provider for Oracle in this sample. To do so, comment out the appropriate lines.

	adCmdUnknown = 0
	adCmdText = 1
	adCmdTable = 2
	adCmdText = 1
	adParamInput = 1
	adParamOutput = 2
	adInteger = 3
	adUseClient = 3
	adOpenStatic = 3

	Dim cnnOracle
	Dim cmdStoredProc
	Dim rsEmp

	'This code creates a connection object.
	Set cnnOracle = Server.CreateObject("ADODB.Connection")
	cnnOracle.CursorLocation = adUseClient

	'System DSN connection
	'strConn = "DSN=OracleDSN; UID=UserID; PWD=Password"

	'DSN-less connection
	strConn = "DRIVER={Microsoft ODBC for Oracle}; SERVER=DatabaseAlias; UID=UserID; PWD=Password"

	'OLE DB connection
	'strConn = "Provider=MSDAORA.1; Data Source=DatabaseAlias; User ID=UserID; Password=Password"

'Note:  The DatabaseAlias is the name that was created in SQL*Net Easy Configuration or in Net8.

	cnnOracle.Open strConn

	'This code creates a command object.
	Set cmdStoredProc = Server.CreateObject("ADODB.Command")
	Set cmdStoredProc.ActiveConnection = cnnOracle

	'Retrieve only one record
	'cmdStoredProc.CommandText = "{call packperson.oneperson(?,{resultset 2, ssn, fname, lname})}"
	'cmdStoredProc.CommandType = adCmdText
	'cmdStoredProc.Parameters.Append cmdStoredProc.CreateParameter("wildcard",adInteger,adParamInput)

	'Retrieve all records.
	cmdStoredProc.CommandText = "{call packperson.allperson({resultset 9, ssn, fname, lname})}"
	cmdStoredProc.CommandType = adCmdText

	'This code creates a recordset object.
	Set rsEmp = Server.CreateObject("ADODB.Recordset")
	rsEmp.CursorType = adOpenStatic

	Set rsEmp.Source = cmdStoredProc

	'Set the parameter for to get only one record
	'cmdStoredProc(0) = 555662222
