Übergeben des Arrays an die Oracle-Prozedur von c #

  1. Definieren Sie einen Array-Typ und eine Prozedur:

    CREATE or replace PACKAGE Testpackage AS 
      TYPE Areas_t is table of VARCHAR(100) index by BINARY_INTEGER;
      PROCEDURE TESTPROCEDURE(Areas IN Areas_t);       
    END Testpackage; 
    
  2. C#-Routine:

    public void InsertQuestion(IEnumerable<string> area_list)
    {
        var connect = new OracleConnection("YOUR CONNECTION STRING");
    
        var command = new OracleCommand("BEGIN Testpackage.Testprocedure(:Areas); END;", connect);
    
        connect.Open();
    
        var arry = command.Parameters.Add("Areas", OracleDbType.Varchar2);
    
        arry.Direction = ParameterDirection.Input;
        arry.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
        arry.Value = area_list.ToArray();
        arry.Size = area_list.Count();
        arry.ArrayBindSize = area_list.Select(_ => _.Length).ToArray();
        arry.ArrayBindStatus = Enumerable.Repeat(OracleParameterStatus.Success, area_list.Count()).ToArray();
    
        command.ExecuteNonQuery();
    
        connect.Close();
    }
