Calling Stored Procedures
You can invoke a stored procedure using DB2Command in the same way as any other SQL stored procedure. To instantiate a DB2Command object, provide the name of the stored procedure and a DB2Connection instance as arguments to the constructor. Set the value of the CommandType property to "StoredProcedure" and add the parameters as key-value pairs to the Parameters collection of the DB2Command instance.
C#
string connectionString = "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test";
using (DB2Connection connection = new DB2Connection(connectionString)) {
DB2Command cmd = new DB2Command("CleanCar", connection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new DB2Parameter("@Url", "http://myserver/myfeed/"));
// Add other parameters as needed ...
DB2DataReader rdr = cmd.ExecuteReader();
while (rdr.Read()) {
for (int i = 0; i < rdr.FieldCount; i++) {
Console.WriteLine(rdr.GetName(i) + " --> " + rdr[i]);
}
Console.WriteLine();
}
}
VB.NET
Dim connectionString As String = "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test"
Using connection As New DB2Connection(connectionString)
Dim cmd As New DB2Command("CleanCar", connection)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New DB2Parameter("@Url", "http://myserver/myfeed/"))
' Add other parameters as needed ...
Dim rdr As DB2DataReader = cmd.ExecuteReader()
While rdr.Read()
For i As Integer = 0 To rdr.FieldCount - 1
Console.WriteLine(rdr.GetName(i) + " --> " + rdr(i))
Next
Console.WriteLine()
End While
End Using
Alternatively, you can set the parameters of a stored procedure in the text of the command. The support for stored procedure statements follows the standard form shown below:
"EXECUTE my_proc @first = 1, @second = 2, @third = 3;" "EXEC my_proc @first = 1, @second = 2, @third = 3;"
To execute a parameterized query, add parameters as key-value pairs to the Parameters collection of the DB2Command instance.
C#
string connectionString = "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test";
using (DB2Connection connection = new DB2Connection(connectionString)) {
DB2Command cmd = new DB2Command("EXECUTE CleanCar Url = @Url;", connection);
cmd.Parameters.Add(new DB2Parameter("@Url", "http://myserver/myfeed/"));
// Add other parameters as needed ...
DB2DataReader rdr = cmd.ExecuteReader();
while (rdr.Read()) {
for (int i = 0; i < rdr.FieldCount; i++) {
Console.WriteLine(rdr.GetName(i) + " --> " + rdr[i]);
}
Console.WriteLine();
}
}
VB.NET
Dim connectionString As String = "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test"
Using connection As New DB2Connection(connectionString)
Dim cmd As New DB2Command("EXECUTE CleanCar Url = @Url;", connection)
cmd.Parameters.Add(New DB2Parameter("@Url", "http://myserver/myfeed/"))
' Add other parameters as needed ...
Dim rdr As DB2DataReader = cmd.ExecuteReader()
While rdr.Read()
For i As Integer = 0 To rdr.FieldCount - 1
Console.WriteLine(rdr.GetName(i) + " --> " + rdr(i))
Next
Console.WriteLine()
End While
End Using
