This example demonstrates how to retrieve OracleObject instance from server and display its elements. To create required type and table and fill it with data you can use the following script:
CREATE TYPE TAddress AS OBJECT (
Country VARCHAR2(30),
City VARCHAR2(30),
Street VARCHAR2(30),
Apartment NUMBER
);
CREATE TABLE EmpObject (
Code NUMBER PRIMARY KEY,
Person VARCHAR2(40),
Address TAddress,
Job VARCHAR2(9)
);
INSERT INTO EmpObject
(Code, Person, Address, Job)
VALUES
(1, 'SMITH', TAddress('UK', 'London', 'Street', 12), 'CLERK');
INSERT INTO EmpObject
(Code, Person, Address, Job)
VALUES
(2, 'JONES', TAddress('USA', 'New York', 'Street', 418), 'MANAGER');
INSERT INTO EmpObject
(Code, Person, Address, Job)
VALUES
(3, 'SCOTT', TAddress('CANADA', 'Ottawa', 'Street', 26),'PRESIDENT');
INSERT INTO EmpObject
(Code, Person, Address, Job)
VALUES
(4, 'MARTIN', TAddress('FRANCE', 'Paris', 'Street', 162), 'ANALYST');
OracleConnection connection = new OracleConnection("User Id=scott;Password=tiger;Data Source=ora");
OracleCommand command = new OracleCommand("SELECT * FROM EmpObject", connection);
connection.Open();
OracleDataReader dataReader = command.ExecuteReader();
try{
int index = dataReader.GetOrdinal("Address");
while (dataReader.Read()) {
OracleObject oraObj = dataReader.GetOracleObject(index);
if (!oraObj.IsNull) {
string country = (string)oraObj.GetOracleValue("Country");
string city = (string)oraObj.GetOracleValue("City");
string street = (string)oraObj.GetOracleValue("Street");
decimal Apartment = (decimal)oraObj["Apartment"];
Console.WriteLine(dataReader.GetString(0) + " " + dataReader.GetString(1) + " " + "Adress: " + country + ", " + city + ", " + street + ", "+ Apartment.ToString() + " " + dataReader.GetString(3));
}
}
}
catch (Devart.Data.Oracle.OracleException ex) {
Console.WriteLine(ex.Message);
}
finally{
dataReader.Close();
connection.Close();
}
Dim connection As New OracleConnection("User Id=scott;Password=tiger;Data Source=ora")
Dim command As New OracleCommand("SELECT * FROM EmpObject", connection)
connection.Open()
Dim dataReader As OracleDataReader = command.ExecuteReader()
Try
Dim index As Integer = dataReader.GetOrdinal("Address")
While dataReader.Read()
Dim oraObj As OracleObject = dataReader.GetOracleObject(index)
If Not oraObj.IsNull Then
Dim country As String = oraObj.GetOracleValue("Country")
Dim city As String = oraObj.GetOracleValue("City")
Dim street As String = oraObj.GetOracleValue("Street")
Dim Apartment As Decimal = oraObj("Apartment")
Console.WriteLine(dataReader.GetString(0) & " " & dataReader.GetString(1) & " " & "Adress: " & country & ", " & city & ", " & street & ", " & Apartment.ToString() & " " & dataReader.GetString(3))
End If
End While
Catch ex As Devart.Data.Oracle.OracleException
Console.WriteLine(ex.Message)
Finally
dataReader.Close()
connection.Close()
End Try
