Please help with an embedded query (INSERT RETURNING BULK COLLECT INTO)

Question

I am trying to write a query inside the C# code where I would insert values into a table in bulk using bind variables. But I also I would like to receive a bulk collection of generated sequence number IDs for the REQUEST_ID. I am trying to use RETURNING REQUEST_ID BULK COLLECT INTO :REQUEST_IDs clause where :REQUEST_IDs is another bind variable
Here is a full query that use in the C# code
string sql = "INSERT INTO REQUESTS_TBL(REQUEST_ID, CID, PROVIDER_ID, PROVIDER_NAME, REQUEST_TYPE_ID, REQUEST_METHOD_ID, " +
"SERVICE_START_DT, SERVICE_END_DT, SERVICE_LOCATION_CITY, SERVICE_LOCATION_STATE, " +
"BENEFICIARY_FIRST_NAME, BENEFICIARY_LAST_NAME, BENEFICIARY_DOB, HICNUM, CCN, " +
"CLAIM_RECEIPT_DT, ADMISSION_DT, BILL_TYPE, LANGUAGE_ID, CONTRACTOR_ID, PRIORITY_ID, " +
"UNIVERSE_DT, REQUEST_DT, BENEFICIARY_M_INITIAL, ATTENDING_PROVIDER_NUMBER, " +
"BILLING_NPI, BENE_ZIP_CODE, DRG, FINAL_ALLOWED_AMT, STUDY_ID, REFERRING_NPI) " +
"VALUES " +
"(SQ_CDCDATA.NEXTVAL, :CIDs, :PROVIDER_IDs, :PROVIDER_NAMEs, :REQUEST_TYPE_IDs, :REQUEST_METHOD_IDs, " +
":SERVICE_START_DTs, :SERVICE_END_DTs, :SERVICE_LOCATION_CITYs, :SERVICE_LOCATION_STATEs, " +
":BENEFICIARY_FIRST_NAMEs, :BENEFICIARY_LAST_NAMEs, :BENEFICIARY_DOBs, :HICNUMs, :CCNs, " +
":CLAIM_RECEIPT_DTs, :ADMISSION_DTs, :BILL_TYPEs, :LANGUAGE_IDs, :CONTRACTOR_IDs, :PRIORITY_IDs, " +
":UNIVERSE_DTs, :REQUEST_DTs, :BENEFICIARY_M_INITIALs, :ATTENDING_PROVIDER_NUMBERs, " +
":BILLING_NPIs, :BENE_ZIP_CODEs, :DRGs, :FINAL_ALLOWED_AMTs, :STUDY_IDs, :REFERRING_NPIs) " +
" RETURNING REQUEST_ID BULK COLLECT INTO :REQUEST_IDs";
int[] REQUEST_IDs = new int[range];
cmd.Parameters.Add(":REQUEST_IDs", OracleDbType.Int32, REQUEST_IDs, System.Data.ParameterDirection.Output);
However, when I run this query, it gives me a strange error ORA-00925: missing INTO keyword. I am not sure what that error means since I am not missing any INTOs
Please help me resolve this error or I would appreciate a different solution
Thank you

It seems you are not doing a bulk insert but rather an array bind.
(Which you will also find that it is problematic to do an INSERT with a bulk collect returning clause (while this works just fine for update/deletes) :
http://www.oracle-developer.net/display.php?id=413)
But you are using array bind, so you simply just need to use a
... Returning REQUEST_ID INTO :REQUEST_IDand that'll return you a Rquest_ID[]
see below for a working example (I used a procedure but the result is the same)
//Create Table Zzztab(Deptno Number, Deptname Varchar2(50) , Loc Varchar2(50) , State Varchar2(2) , Idno Number(10)) ;
//create sequence zzzseq ;
//CREATE OR REPLACE PROCEDURE ZZZ( P_DEPTNO   IN ZZZTAB.DEPTNO%TYPE,
//                      P_DEPTNAME IN ZZZTAB.DEPTNAME%TYPE,
//                      P_LOC      IN ZZZTAB.LOC%TYPE,
//                      P_State    In Zzztab.State%Type ,
//                      p_idno     out zzztab.idno%type
//         IS
//Begin
//      Insert Into Zzztab (Deptno,   Deptname,   Loc,   State , Idno)
//                  Values (P_Deptno, P_Deptname, P_Loc, P_State, Zzzseq.Nextval)
//                  returning idno into p_idno;
//END ZZZ;
//Drop Procedure Zzz ;
//Drop Sequence Zzzseq ;
//drop Table Zzztab;
  class ArrayBind
    static void Main(string[] args)
      // Connect
        string connectStr = GetConnectionString();
      // Setup the Tables for sample
      Setup(connectStr);
      // Initialize array of data
      int[]    myArrayDeptNo   = new int[3]{1, 2, 3};
      String[] myArrayDeptName = {"Dev", "QA", "Facility"};
      String[] myArrayDeptLoc  = {"New York", "Chicago", "Texas"};
      String[] state = {"NY","IL","TX"} ;
      OracleConnection connection = new OracleConnection(connectStr);
      OracleCommand    command    = new OracleCommand (
        "zzz", connection);
      command.CommandType = CommandType.StoredProcedure;
      // Set the Array Size to 3. This applied to all the parameter in
      // associated with this command
      command.ArrayBindCount = 3;
      command.BindByName = true;
      // deptno parameter
      OracleParameter deptNoParam = new OracleParameter("p_deptno",OracleDbType.Int32);
      deptNoParam.Direction       = ParameterDirection.Input;
      deptNoParam.Value           = myArrayDeptNo;
      command.Parameters.Add(deptNoParam);
      // deptname parameter
      OracleParameter deptNameParam = new OracleParameter("p_deptname", OracleDbType.Varchar2);

      //P_STATE -- -ARRAY
      OracleParameter stateParam = new OracleParameter("P_STATE", OracleDbType.Varchar2);
      stateParam.Direction = ParameterDirection.Input;
      stateParam.Value = state;
      command.Parameters.Add(stateParam);
              //idParam-- ARRAY
      OracleParameter idParam = new OracleParameter("p_idno", OracleDbType.Int64 );
      idParam.Direction = ParameterDirection.Output ;
      idParam.OracleDbTypeEx = OracleDbType.Int64;
      command.Parameters.Add(idParam);
      try
        connection.Open();
        command.ExecuteNonQuery ();
        Console.WriteLine("{0} Rows Inserted", command.ArrayBindCount);
          //now cycle through the output param array
        foreach (Int64 i in (Int64[])idParam.Value)
            Console.WriteLine(i);
      catch (Exception e)
        Console.WriteLine("Execution Failed:" + e.Message);
      finally
        // connection, command used server side resource, dispose them
        // asap to conserve resource
        connection.Close();
        command.Dispose();
        connection.Dispose();
