将数组传递给存储过程

我必须将数组和字符串传递给存储过程并返回数据表

C＃方：

public DataTable fetchRequested(string [] empID, string [] account, string [] refNo, string orgID, string Id, DateTime valueDate) { string connetionString = null; OracleConnection con; OracleDataAdapter objAdapter = null; OracleCommand objComm = new OracleCommand(); connetionString = @"Data Source= Payment_devlope; User ID=ORGPAYMENT;Password=OrgPayment"; con = new OracleConnection (connetionString); try { con.Open(); objComm.Connection = con; objComm.CommandType = CommandType.StoredProcedure; objComm.CommandText = "PKG_REPORTS.Requested_Payment"; // Add and Set Procedure Parameters //////////////////////////////////////////////////////////////////// objComm.Parameters.Add("p_empID", OracleDbType.NVarchar2, 100); objComm.Parameters["p_empID"].CollectionType = OracleCollectionType.PLSQLAssociativeArray; if (empID.Length != 0) objComm.Parameters["p_empID"].Value = empID; //////////////////////////////////////////////////////////////////// objComm.Parameters.Add("p_account", OracleDbType.NVarchar2, 100); objComm.Parameters["p_account"].CollectionType = OracleCollectionType.PLSQLAssociativeArray; if (account.Length != 0) objComm.Parameters["p_account"].Value = account; //////////////////////////////////////////////////////////////////// objComm.Parameters.Add("p_refrence_number", OracleDbType.NVarchar2, 100); objComm.Parameters["p_refrence_number"].CollectionType = OracleCollectionType.PLSQLAssociativeArray; if (refNo.Length != 0) objComm.Parameters["p_refrence_number"].Value = refNo; //////////////////////////////////////////////////////////////////// objComm.Parameters.Add("p_Organization_Id", OracleDbType.Varchar2); objComm.Parameters["p_Organization_Id"].Direction = ParameterDirection.Input; if (!String.IsNullOrEmpty(orgID)) { objComm.Parameters["p_Organization_Id"].Value = orgID; } //////////////////////////////////////////////////////////////////// objComm.Parameters.Add("p_Id", OracleDbType.Varchar2); objComm.Parameters["p_Id"].Direction = ParameterDirection.Input; if (!String.IsNullOrEmpty(Id)) { objComm.Parameters["p_Id"].Value = Id; } //////////////////////////////////////////////////////////////////// objComm.Parameters.Add("p_Value_date", OracleDbType.Date); objComm.Parameters["p_Value_date"].Direction = ParameterDirection.Input; if (valueDate == null) { objComm.Parameters["p_Value_date"].Value =valueDate; } //////////////////////////////////////////////////////////////////// objComm.Parameters.Add("cur_report_data", OracleDbType.RefCursor); objComm.Parameters["cur_report_data"].Direction = ParameterDirection.Output; //////////////////////////////////////////////////////////////////// objAdapter = new OracleDataAdapter(); objAdapter.SelectCommand = objComm; // Filling Dataset with searched result DataSet ds = new DataSet(); objAdapter.Fill(ds,"ReportData"); return ds.Tables["ReportData"]; } finally { if (objAdapter != null) { objAdapter.Dispose(); objAdapter = null; } if (objComm != null) { objComm.Dispose(); objComm = null; } } } 

PL / sql端：

 Procedure Requested_Payment ( p_empID in nvarchar_array := Null , p_account in nvarchar_array := Null, p_refrence_number in nvarchar_array := Null, p_Organization_Id in nvarchar2 := NULL, p_Id in nvarchar2 := NULL, p_Value_date in date := NULL, cur_report_data out Data_Table ) is BEGIN open cur_report_data for SELECT /*+ index(bp,B_PAYMENT_PK) */ org.ORGANIZATION_CODE org_ID, bm.ID, bd.BENEFICIARY_organization_ID Employee_ID, bd.BENEFICIARY_NAME Employee_Name, bp.REFERENCE_NUMBER Reference_No, bp.CREDIT_ACCOUNT ACC_NO, ct.ENGLISH_DESCRIPTION Reason, from Organization org inner join B_MASTER bm on bm.organization_CODE = org.organization_CODE inner join B_DETAIL bd on bd.MASTER_SEQUENCE_ID = bm.MASTER_SEQUENCE_ID inner join B_payment bp on bp.MASTER_SEQUENCE_ID = bm.MASTER_SEQUENCE_ID inner join CODE_TABLE ct on ct.code = BP.PAYMENT_STATUS where (p_Organization_Id is Null or org.organization_CODE = p_Organization_Id) AND (p_Id is Null OR bm.BATCH_NUMBER = p_Id) AND (p_Value_date is null or bm.Debit_VALUE_DATE between startofday(p_Value_date) and endofday(p_Value_date)) AND (ct.GROUP_CODE = 4) AND (BD.DETAIL_SEQUENCE_ID = BP.DETAIL_ID) AND (p_empID is Null or bd.BENEFICIARY_organization_ID in (Select column_value FROM TABLE (p_empID))) AND (p_account is null or bp.CREDIT_ACCOUNT in (Select column_value FROM TABLE (p_account))) AND (p_refrence_number is null or bp.REFERENCE_NUMBER in (Select column_value FROM TABLE (p_account))) ; end Requested_Payment ; 

创建类型：

 CREATE OR REPLACE TYPE ORGPAYROLL.NVARCHAR_ARRAY AS TABLE OF VARCHAR2(100) 

当其中一个数组为空时，我在Visual Studio中收到此错误：

OracleParameter.Value无效

当我传递所有三个数组时，我收到此错误：

ORA-06550：第1行第7栏：
PLS-00306：调用’REQUESTED_PAYMENT’时参数的数量或类型错误
ORA-06550：第1行第7栏：

ORA-06550：第1行第7栏：

ORA-06550：第1行第7栏：
PL / SQL：语句被忽略

您的存储过程不应该期望表类型，而应该期望associative array 。 您可以在存储过程中将其转换为所需的类型。 查看此链接更多详细信息
