Resolved Oracle Stored Procedure Retrieving Data

I've been attempting to utilize an Oracle Stored Procedure in a DataWindow to retrieve data, however upon retrieval I receive the following error.

ORA-06550 - Identifier '{indentifier}' must be declared.

The issue can be created in the DW painter.

 

I'm using Oracle ODBC drivers (doesn't require the client) and I'm not sure if that is the cause at this point. 

I have no issues with MSSQL stored procedures. Just the ORA ones are not playing nice.

I've provided the DW (dtb_sp_simple_select_char) and PL/SQL (TEST_SP_ex_simple_select.txt) for the procedure.

Any guidance would be appreciated.

- Mike

Hi,

It seems that your best shot is to go with the native driver (sqlca.dbms = ORA), that's what we use and it works great!

Hi,

I've compared what we do (with Oracle client Native driver) and the only difference I see is that 

outData IN OUT SYS_REFCURSOR would be declared without the "IN" keyword:

outData OUT SYS_REFCURSOR.

Give it a try?

When I have a working connection to my work pc, I'll look at the dw with the parameters. There's a "0" in yours which I don't understand why it's there. (Maybe in our dw it's there too!).

regards.

I've checked on our own DW and indeed, that weird "0" is also there in the arguments:

1 execute CREDIT.SP_DW_TRANS_LIST3;0 AS_ITEM_CUSTOMER = :AS_ITEM_CUSTOMER, .......

So that's not the problem.

Thanks, Chris.

I will get that a try.  By any chance is there a good tutorial/example on Oracle DB Objects and DataWindows somewhere you can point me to? Most the ones I have found have been more general.

Not in the PB documentation realm but there should be "tons" out there in the various Oracle forums. Even PB related material as PB has been interacting with Oracle DBMS versions since the early days of PowerSoft PB versions.

Hi Mike;

  ODBC has challenges for BLOB data stream processing and must be configured exactly for this to work.

   Have you tried the native "ORA" DB Client driver instead?
