The SQL statement or stored procedure to execute. The default value is an empty string ("").

When CommandType value is Text, property CommandText should contain text of a query that must be run on the server.

When the value is StoredProcedure, property CommandText must be a name of a procedure to execute.

When the value is set to TableDirect, CommandText must be name of a table you want to get all data from. All rows and columns are retrieved.

{ 
  OracleCommand myCommand = new OracleCommand(); 
  myCommand.CommandText = "SELECT * FROM Test.Dept ORDER BY DeptNo"; 
}

Public Sub CreateCommand()
   Dim myCommand As New OracleCommand()
   myCommand.CommandText = "SELECT * FROM Test.Dept ORDER BY DeptNo"
