Question

I have this Code:

 OracleConnection myOracleConnection = new OracleConnection(connectionString);
 myOracleConnection.Open();
 OracleCommand command = myOracleConnection.CreateCommand();
 command.CommandText = 
      SchemaDifferenceFinder.Model.SQLStatements.MissingTables.DropTable;
 command.CommandType = System.Data.CommandType.Text;
 command.ExecuteNonQuery();
 myOracleConnection.Close();  

On Line 4 you find “MissingTables“. Thats a Class.

This whole Code will repeat 7 times, everything is the same, except that this Class changes, by example: “MissingColumns“. But I don’t want to copy/paste the whole code, only to replace this trifle.

What could I do? Something with generics? I could also pass parameters if needed etc. Am grateful for every solution!

Answer 1

private static void ExecuteSQL(string SQL)
{
  OracleConnection myOracleConnection = new OracleConnection(connectionString);
  myOracleConnection.Open();
  OracleCommand command = myOracleConnection.CreateCommand();
  command.CommandText = SQL;
  command.CommandType = System.Data.CommandType.Text;
  command.ExecuteNonQuery();
  myOracleConnection.Close(); 
}

Which can then be called the following way:

Helper.ExecuteSQL(SchemaDifferenceFinder.Model.SQLStatements.MissingTables.DropTable);
