This example demonstrates the Add and Remove parameter methods, the ServerType
parameter property and the ExecuteSQL database method to call a Stored
Procedure and Function (located in ORAEXAMP.SQL). Copy and paste this code into the
definition section of a form. Then press F5.
Sub Form_Load ()
'Declare variables as OLE Objects.
Dim OraSession As OraSession
Dim OraDatabase As OraDatabase
Dim OraDynaset As OraDynaset
'Create the OraSession Object.
Set OraSession = CreateObject("OracleInProcServer.XOraSession")
'Create the OraDatabase Object.
Set OraDatabase = OraSession.OpenDatabase("ExampleDb", "scott/tiger", 0&)
'Add EMPNO as an Input/Output parameter and set its initial value.
OraDatabase.Parameters.Add "EMPNO", 7369, ORAPARM_INPUT
OraDatabase.Parameters("EMPNO").ServerType = ORATYPE_NUMBER
'Add ENAME as an Output parameter and set its initial value.
OraDatabase.Parameters.Add "ENAME", 0, ORAPARM_OUTPUT
OraDatabase.Parameters("ENAME").ServerType = ORATYPE_VARCHAR2
'Add SAL as an Output parameter and set its initial value.
OraDatabase.Parameters.Add "SAL", 0, ORAPARM_OUTPUT
OraDatabase.Parameters("SAL").ServerType = ORATYPE_NUMBER
'Execute the Stored Procedure Employee.GetEmpName to retrieve ENAME.
' This Stored Procedure can be found in the file ORAEXAMP.SQL.
OraDatabase.ExecuteSQL ("Begin Employee.GetEmpName (:EMPNO, :ENAME); end;")
'Display the employee number and name.
'Execute the Stored Function Employee.GetSal to retrieve SAL.
' This Stored Function can be found in the file ORAEXAMP.SQL.
OraDatabase.ExecuteSQL ("declare SAL number(7,2); Begin
:SAL:=Employee.GetEmpSal (:EMPNO); end;")
'Display the employee name, number and salary.
MsgBox "Employee " & OraDatabase.Parameters("ENAME").value & ", #" &
OraDatabase.Parameters("EMPNO").value & ",Salary=" & OraDatabase.Parameters("SAL").value
'Remove the Parameters.
OraDatabase.Parameters.Remove "EMPNO"
OraDatabase.Parameters.Remove "ENAME"
OraDatabase.Parameters.Remove "SAL"
End Sub
