You can invoke a stored procedure using ApacheHBaseCommand in the same way as any other SQL stored procedure. To instantiate a ApacheHBaseCommand object, provide the name of the stored procedure and a ApacheHBaseConnection 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 ApacheHBaseCommand instance.

C#

string connectionString = "Server=127.0.0.1;Port=8080;";

using (ApacheHBaseConnection connection = new ApacheHBaseConnection(connectionString)) {
  ApacheHBaseCommand cmd = new ApacheHBaseCommand("CreateTable", connection);
  cmd.CommandType = CommandType.StoredProcedure; 
  cmd.Parameters.Add(new ApacheHBaseParameter("@TableName", "Orders"));
  // Add other parameters as needed ...

  ApacheHBaseDataReader 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=127.0.0.1;Port=8080;"

Using connection As New ApacheHBaseConnection(connectionString)
  Dim cmd As New ApacheHBaseCommand("CreateTable", connection)
  cmd.CommandType = CommandType.StoredProcedure
  cmd.Parameters.Add(New ApacheHBaseParameter("@TableName", "Orders"))
  ' Add other parameters as needed ...

  Dim rdr As ApacheHBaseDataReader = 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 ApacheHBaseCommand instance.

C#

string connectionString = "Server=127.0.0.1;Port=8080;";

using (ApacheHBaseConnection connection = new ApacheHBaseConnection(connectionString)) {
  ApacheHBaseCommand cmd = new ApacheHBaseCommand("EXECUTE CreateTable TableName = @TableName;", connection); 
  cmd.Parameters.Add(new ApacheHBaseParameter("@TableName", "Orders"));
  // Add other parameters as needed ...

  ApacheHBaseDataReader 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=127.0.0.1;Port=8080;"

Using connection As New ApacheHBaseConnection(connectionString)
  Dim cmd As New ApacheHBaseCommand("EXECUTE CreateTable TableName = @TableName;", connection)
  cmd.Parameters.Add(New ApacheHBaseParameter("@TableName", "Orders"))
  ' Add other parameters as needed ...

  Dim rdr As ApacheHBaseDataReader = 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
