C# 如何从.NET前端在Oracle中使用用户定义的数据类型参数执行Oracle存储过程

我使用Oracle作为后端，C#作为前端

Oracle包声明如下：

CREATE OR REPLACE PACKAGE SamplePackage IS

TYPE t_number IS TABLE OF NUMBER INDEX BY PLS_INTEGER;

PROCEDURE SampleProc(run_no IN t_number, Id IN t_number);

END;


CREATE OR REPLACE PACKAGE BODY SamplePackage IS

  PROCEDURE SampleProc(run_no IN t_number, Id IN t_number) IS

    l_cnt      NUMBER := 0;
  
  BEGIN
  
    FOR i IN 1 .. Id.count
    LOOP
    
      INSERT INTO SampleSchema.SampleTable
        (run_no,
         Id)
      VALUES
        (run_no(i),
         Id(i));
    
      -- commit every 1000 rows
      l_cnt := l_cnt + 1;
    
      IF (MOD(l_cnt,
              1000) = 0) THEN
        COMMIT;
      END IF;
    
    END LOOP;
    COMMIT;
  
  EXCEPTION
    WHEN OTHERS THEN
      raise_application_error(-20001,
                              'SamplePackage.SampleProc: ' || SQLERRM || dbms_utility.format_error_backtrace);
  END SampleProc;

END;

string ConnectionString = ConfigurationManager.ConnectionStrings["oracleConnection"].ConnectionString.ToString();
        
using (var connection = new OracleConnection(ConnectionString))
{
    connection.Open();

    double[] run_no = new double[2];
    double[] Id = new double[2];

    run_no[0] = 10;
    run_no[1] = 12;

    Id[0] = 100;
    Id[1] = 120;

    OracleParameter ora_run_no = new OracleParameter();
    ora_run_no.ParameterName = "run_no";
    ora_run_no.OracleDbType = OracleDbType.Double;
    ora_run_no.Direction = ParameterDirection.Input;
    ora_run_no.UdtTypeName = "t_number";
    ora_run_no.Value = run_no;

    OracleParameter ora_p_quote_id = new OracleParameter();
    ora_Id.ParameterName = "Id";
    ora_Id.OracleDbType = OracleDbType.Double;
    ora_Id.Direction = ParameterDirection.Input;
    ora_Id.UdtTypeName = "t_number";
    ora_Id.Value = Id;

    OracleCommand cmdInsert = new OracleCommand();
    cmdInsert.Connection = connection;
    cmdInsert.CommandType = CommandType.StoredProcedure;
    cmdInsert.CommandText = "SampleSchema.SamplePackage.SampleProc";

    cmdInsert.BindByName = true;
    cmdInsert.ArrayBindCount = Id.Length;

    cmdInsert.Parameters.Add(ora_run_no);
    cmdInsert.Parameters.Add(ora_Id);

    cmdInsert.ExecuteNonQuery();
}

前端C#代码如下：

CREATE OR REPLACE PACKAGE SamplePackage IS

TYPE t_number IS TABLE OF NUMBER INDEX BY PLS_INTEGER;

PROCEDURE SampleProc(run_no IN t_number, Id IN t_number);

END;


CREATE OR REPLACE PACKAGE BODY SamplePackage IS

  PROCEDURE SampleProc(run_no IN t_number, Id IN t_number) IS

    l_cnt      NUMBER := 0;
  
  BEGIN
  
    FOR i IN 1 .. Id.count
    LOOP
    
      INSERT INTO SampleSchema.SampleTable
        (run_no,
         Id)
      VALUES
        (run_no(i),
         Id(i));
    
      -- commit every 1000 rows
      l_cnt := l_cnt + 1;
    
      IF (MOD(l_cnt,
              1000) = 0) THEN
        COMMIT;
      END IF;
    
    END LOOP;
    COMMIT;
  
  EXCEPTION
    WHEN OTHERS THEN
      raise_application_error(-20001,
                              'SamplePackage.SampleProc: ' || SQLERRM || dbms_utility.format_error_backtrace);
  END SampleProc;

END;

string ConnectionString = ConfigurationManager.ConnectionStrings["oracleConnection"].ConnectionString.ToString();
        
using (var connection = new OracleConnection(ConnectionString))
{
    connection.Open();

    double[] run_no = new double[2];
    double[] Id = new double[2];

    run_no[0] = 10;
    run_no[1] = 12;

    Id[0] = 100;
    Id[1] = 120;

    OracleParameter ora_run_no = new OracleParameter();
    ora_run_no.ParameterName = "run_no";
    ora_run_no.OracleDbType = OracleDbType.Double;
    ora_run_no.Direction = ParameterDirection.Input;
    ora_run_no.UdtTypeName = "t_number";
    ora_run_no.Value = run_no;

    OracleParameter ora_p_quote_id = new OracleParameter();
    ora_Id.ParameterName = "Id";
    ora_Id.OracleDbType = OracleDbType.Double;
    ora_Id.Direction = ParameterDirection.Input;
    ora_Id.UdtTypeName = "t_number";
    ora_Id.Value = Id;

    OracleCommand cmdInsert = new OracleCommand();
    cmdInsert.Connection = connection;
    cmdInsert.CommandType = CommandType.StoredProcedure;
    cmdInsert.CommandText = "SampleSchema.SamplePackage.SampleProc";

    cmdInsert.BindByName = true;
    cmdInsert.ArrayBindCount = Id.Length;

    cmdInsert.Parameters.Add(ora_run_no);
    cmdInsert.Parameters.Add(ora_Id);

    cmdInsert.ExecuteNonQuery();
}

这里有些混乱。当我执行.NET代码时，它在

ExecuteNonQuery

处抛出错误，如下所示

ORA-06550:第1行第7列：
PLS-00306:调用“SAMPLEPROC”时参数的数量或类型错误

ORA-06550:第1行第7列：
PL/SQL:忽略语句

在Oracle后端，我使用的是

t\u number

用户定义的数据类型。我唯一需要知道的是如何将其作为数组处理并从C#成功执行。

我对您正在使用的工具一无所知，但是-由于在包中声明了类型，我想说：

ora_Id.UdtTypeName = "t_number";

应该是

ora_Id.UdtTypeName = "SampleSchema.SamplePackage.t_number";

就像你在程序中使用的一样

除此之外，由于您使用的类型是数字表，您可以尝试使用Oracle的内置类型：

sys.odcinumberlist

。

要成功执行，我是否需要为这两个字段分别创建临时表并更改

UdtTypeName

或当前

double[]

数组工作？因为使用

sys.odcinumberlist

修改包和过程需要很长的过程，所以由其他团队处理。它仍然抛出相同的错误；正如我所说，我不知道你使用的工具，所以我不能对此发表评论。我希望你能设法让它工作。我正在使用

ODP.NET

来实现这一点，但我仍然被卡住了。我能够成功地使用

sys.odcinumberlist

。但是我需要它来做你的电话号码。当我将

ora_Id.UdtTypeName

指定为

t_number

时，它无法识别。出路是什么？
