How to pass a table-valued parameter from C# to Oracle stored procedure

问题

I have an Oracle stored procedure named CREATE_CASE_EXL:

PROCEDURE  CREATE_CASE_EXL(P_RICdata RICTab,
                       P_sACTION_TYPE IN VARCHAR2);

where RICTab is a custom type:

TYPE RICTab IS TABLE OF MMSRRicRec  INDEX BY BINARY_INTEGER;

TYPE MMSRRicRec IS RECORD
 ( RIC        VARCHAR2(32),
   FID_NO     NUMBER(8),
   REC_ID     NUMBER(8),
   MMS_ACTION VARCHAR2(1)
 );

I run this code in PL/SQL to execute CREATE_CASE_EXL:

DECLARE
pTE_RICS     RICTab 

BEGIN
    pTE_RICS(1).RIC  := 'RIC1';
    pTE_RICS(1).FID_NO := NULL;
    pTE_RICS(1).REC_ID := 3;
    pTE_RICS(1).MMS_ACTION := 'A';

    pTE_RICS(1).RIC  := 'RIC2';
    pTE_RICS(1).FID_NO := NULL;
    pTE_RICS(1).REC_ID := 4;
    pTE_RICS(1).MMS_ACTION := 'A';

    CREATE_CASE_EXL( pTE_RICS , 'A');

END;

I need to execute something similar in .NET. Can you please advise how could I pass a parameter as a table of data to an Oracle stored procedure? Should I use a UDT for this task?

回答1:

actually I found that it's supported, but you have to use Oracle UDT for that purpose.

Here's link to the resources which I used to solve the issue: http://appsjack.blogspot.co.uk/2010/09/pass-custom-udt-types-to-oracle-stored.html

Big thanks to everybody for the advices!

回答2:

I don't think this is currently supported. I think you will have to use some workaround.

1) XML

2) smart associative array

pTE_RICS(1).RIC  := 'RIC1'; -> pTE_RICS("item[0].RIC")  := 'RIC1';

We were choosing between them a year ago and we chose XML. (and also trying to get your case working but without success)
