Я пытаюсь выполнить блок PL / Sql с помощью OracleClientProvider в .Net.Я использую язык c #, база данных oracle10g
На самом деле я делаю следующее:
//ConnectionSting is the connection String
OracleConnection connection = new OracleConnection(connectionString);
OracleCommand cmd = new OracleCommand();
cmd.Connection = connection;
//queryFile contains the PL/SQL Script I am trying to execute;
String queryFile = ConfigurationManager.AppSettings["MasterDbScript"];
String dataInFile = new StreamReader(queryFile).ReadToEnd();
cmd.CommandText = dataInFile;
// Open the connection
connection.Open();
cmd.ExecuteNonQuery();
//close the connection
connection.close();
Блок PL / SQL выполняется правильно, когда я запускаю его через клиент ORACLEно здесь выдается ошибка ORA-00922: отсутствует или недействительна опция
Я хочу спросить: 1. Сценарии выполняются иначе, чем обычный запрос?2. Что я делаю не так?
