Question

我已经习惯了SQL Server一段时间以来一直在努力解决这个问题。我有以下代码，并且我已经验证了OracleDbType是正确的并且已经验证传递给参数的实际值是否匹配。我认为我的问题可能取决于返回值。它只是给我行数。我在某处读到了返回参数必须设置在顶部。我得到的具体错误是，

PLS-00306：调用\ u0027INSERT_REC \ u0027的参数的数量或类型错误 ORA-06550：第1行第7列：\ nPL / SQL：忽略语句

存储过程是：

PROCEDURE INSERT_REC
(
  A_MILL_CENTER     IN GRO_OWNER.MOVEMENT.MILL_CENTER%TYPE,     --# VARCHAR2(10)
  A_INGREDIENT_CODE IN GRO_OWNER.MOVEMENT.INGREDIENT_CODE%TYPE, --# VARCHAR2(50)
  A_FEED_CODE       IN GRO_OWNER.MOVEMENT.FEED_CODE%TYPE,       --# VARCHAR2(30)
  --# A_MOVEMENT_TYPE should be ‘RECEIPT’ for ingredient receipts
  A_MOVEMENT_TYPE   IN GRO_OWNER.MOVEMENT.MOVEMENT_TYPE%TYPE,   --# VARCHAR2(10)
  A_MOVEMENT_DATE   IN VARCHAR2,                                --# VARCHAR2(10)
  A_MOVEMENT_QTY    IN GRO_OWNER.MOVEMENT.MOVEMENT_QTY%TYPE,    --# NUMBER(12,4)
  --# A_INVENTORY_TYPE should be ‘INGREDIENT’ or ‘FINISHED’
  A_INVENTORY_TYPE  IN GRO_OWNER.MOVEMENT.INVENTORY_TYPE%TYPE,  --# VARCHAR2(10)
  A_CREATE_USERID   IN GRO_OWNER.MOVEMENT.CREATE_USERID%TYPE,   --# VARCHAR2(20)
  A_RETURN_VALUE    OUT NUMBER                                  --# NUMBER(10,0)
);

我的代码如下：

 for (int i=0; i < theData.Length -1; i+=3)
                {
//3 items hardcoded for now

string millCenter = "0010260510";
string movementType = "RECEIPT";
string feedCode = "test this";
string userID = "GRIMMETTM";
string inventoryType = "INGREDIENT"; //set to FINISHED for feed stuff
string movementDate = theData[i];
string ingCode = System.Text.RegularExpressions.Regex.Match(
        theData[i + 1], @"^([0-9]*)").ToString();
//int pounds = Convert.ToInt32(theData[i + 2].Replace(",", ""));
int pounds = 100;

//setup parameters

OracleParameter p9 =
    new OracleParameter("A_RETURN_VALUE", OracleDbType.Int32, 30);
p9.Direction = ParameterDirection.ReturnValue;
oraCmd.Parameters.Add(p9);

OracleParameter p1 =
    new OracleParameter("A_MILL_CENTER", OracleDbType.Varchar2, 10);
p1.Direction = ParameterDirection.Input;
p1.Value = millCenter;
oraCmd.Parameters.Add(p1);

OracleParameter p2 =
    new OracleParameter("A_INGREDIENT_CODE", OracleDbType.Varchar2, 50);
p2.Direction = ParameterDirection.Input;
p2.Value = ingCode;
oraCmd.Parameters.Add(p2);

OracleParameter p3 =
    new OracleParameter("A_FEED_CODE", OracleDbType.Varchar2, 30);
p3.Direction = ParameterDirection.Input;
p3.Value = feedCode;
oraCmd.Parameters.Add(p3);

OracleParameter p4 =
    new OracleParameter("A_MOVEMENT_TYPE", OracleDbType.Varchar2, 10);
p4.Direction = ParameterDirection.Input;
p4.Value = movementType;
oraCmd.Parameters.Add(p4);

OracleParameter p5 =
    new OracleParameter("A_MOVEMENT_DATE", OracleDbType.Varchar2, 10);
p5.Direction = ParameterDirection.Input;
p5.Value = movementDate;
oraCmd.Parameters.Add(p5);

OracleParameter p6 =
    new OracleParameter("A_MOVEMENT_QTY", OracleDbType.Int32, 12);
p6.Direction = ParameterDirection.Input;
p6.Value = pounds;
oraCmd.Parameters.Add(p6);

OracleParameter p7 =
    new OracleParameter("A_INVENTORY_TYPE", OracleDbType.Varchar2, 10);
p7.Direction = ParameterDirection.Input;
p7.Value = inventoryType;
oraCmd.Parameters.Add(p7);

OracleParameter p8 =
    new OracleParameter("A_CREATE_USERID", OracleDbType.Varchar2, 20);
p8.Direction = ParameterDirection.Input;
p8.Value = userID;
oraCmd.Parameters.Add(p8);


//open and execute
oraConn.Open();
oraCmd.ExecuteNonQuery();
oraConn.Close();

Answer 1

您是否尝试过最后一次添加RETURN_VALUE参数而不是第一次？如果我记得，当通过Oracle提供程序调用Oracle存储过程时，参数必须完全相同。

Answer 2

A_RETURN_VALUE的ParameterDirection应为ParameterDirection.Output

Answer 3

无法从您的示例中判断，但是您是否可以在for循环范围之外声明oraCmd对象？我没有在示例中看到声明，但如果是这种情况，那么每次迭代都会将所有Oracle参数添加到数组中，并且在第一次运行之后的任何运行中都会有太多。
