Has anyone faced this issue before. I am trying to use the BizTalk SQL Adapter to read data from stored procedure using ( for xml auto, elements, xmldata ). the data is returned normally (I push it to physical file and the data is there) but after I map this returned data to a another schema (with similar structure), the file generated after the transform is always empty file. I want to know what is wrong.
Generate the schema with xmldata then after that replace it with root('rootName') then update the schema by adding a child element rootName and make it as a father element for the xml data right after the auto generated root

I'm trying to use RJDBC to connect to a SAP HANA database and query for a temporary table, which is stored with a #-prefix:
test <- dbGetQuery(jdbcConnection,
"SELECT * FROM #CONTROL_TBL")
# Error in [...]: invalid table name: Could not find table/view #CONTROL_TBL in schema USER
If I execute the SQL statement in HANA, it works perfectly fine. I'm also able to query for permanent tables. Therefore I assume that R doesn't pass over the hashtag. Inserting escapes like "SELECT * FROM \\#CONTROL_TBL" however didn't solve my problem.
It's not possible to query for the data of a local or global temporary table from a different session, since they are by definition session-specific. In the case of a global temporary table one can query for the metadata of the table because they are shared across sessions.
Source: Tutorial for HANA temporary tables
You have to double-quote the table because it contains special characters, see SAP Help, identifiers for details.
test <- dbGetQuery(jdbcConnection,
'SELECT * FROM "#CONTROL_TBL"')
See also related discussion on stackoverflow.
Ok, local temporary tables are always only visible to the session in which they've been defined, while global temporary tables are visible just like normal tables, but the data is session private.
So, if you created the local temp. table (name starts with #) in a different session, then no wonder it cannot be found.
For your example, the question is: why do you need a temporary table in the first place?
Instead of that, you could e.g. define a view or a table function to select data from.
I came across a scenario where I need to insert the WCF-SAP Response to a SQL staging table column which has XML datatype.
Is there any possibility to use BizTalk Map as I have other columns in the staging table to populate values.
This is solved by generating the schema in the assignment shape and inserted the XML into the SQL Column.
I faced some issues with Parent node accepts only Text where mine is a XML. That is also fixed when I used CDATA format.
I used Listing 3 in the following link to create a FIELDPROC program QGPL/MOBHOMEPAS which should encrypt a variable char column Field Encryption in DB2 for i
I compiled the RPGLE program and I created a separate database DBMLIB/UMAAAP00 as follows
A R UMAAAF00 TEXT('-
A TEST ENCRYPTION')
A*
A IPIAAA 20A VARLEN(20)
A KYGAAA 11S 2 COLHDG('SALARY')
I then use strsql to alter the table and protect IPIAAA
ALTER TABLE DBMLIB/UMAAAP00 alter column IPIAAA set FIELDPROC
QGPL.MOBHOMEPAS
ALTER COMPLETED FOR TABLE UMAAAP00 IN DBMLIB.
For some reason when I go in to add entries through upddta directly to the file itself and then do a wrkqry to query and file and view them I don't see them as encrypted.
Is this not how it's supposed to work? Is anyone able to assist me with the logic? Ultimately, I'd like to create a simple table from scratch that has a single 20 character or so password column as encrypted.
If the code being utilized for the named FieldProc program QGPL.MOBHOMEPAS was modeled-after [an effective copy of] the source code that was found at the URL from the OP [which BTW includes a position-to request to the comments section... Why?], then that code is implemented using the base-level of the DB2 for IBM i 7.1 SQL FieldProc support, not the next [enhanced] level of support in which the masking feature was added. That is, every invocation other than for function-code=8 will necessarily always be an Encode or a Decode operation for which any masking of the data is unsupported, because changing the data [with that level of support] would corrupt the data in the TABLE.
Note [from http://www.mcpressonline.com/rpg/db2-field-procedures-finally-support-conditional-masking.html] the differences in the coding requirements described for the pre-masking-support [eight parameters] and since-masking-support [nine parameters] as the pre-requisite to have the Run Query (RUNQRY) and Update Data (UPDDTA) features mask the data that is presented to the user:
The new FieldProc Masking support revolves around two main components.
The first component is a new parameter that was added to the parameter
lists that the DB2 engine passes to the FieldProc program on each
decode call. This new parameter controls whether or not the FieldProc
program can return a masked value. There are some DB2 operations—such
as the RGZPFM (Reorganize Physical File Member) command and trigger
processing—that always require the clear-text version of the data to
be returned. The second component is a new special SQLState value
('09501') that is to be returned by the FieldProc program whenever it
is passed a masked value on the encode call. This prevents the masked
value from being encoded, which would result in the original data
value being lost. When this special SQLState value is returned, DB2
will ignore the encoded value that is passed back by the FieldProc
program and instead use the value that's currently stored in the
record image for that column.
For some reason when I go in to add entries through upddta directly to
the file itself and then do a wrkqry to query and file and view them I
don't see them as encrypted. Is this not how it's supposed to work?
No, that's not how it's supposed to work. The data will be encoded on disk only.
When you view the data it will be decoded automatically by the FIELDPROC program no matter what you're using to view it (WRKQRY [yuck], DFU, STRSQL, whatever). This is how it works regardless of field masking (which is different/additional functionality).
Is there some way to create a view that returns a pzPVStream that can be natively parsed by Pega when it executes an RDB?
For instance, maybe a query (in MS SQL Server) that resembled:
SELECT test_tbl_outer.ID, (
select *, 'My-Int-TestClass' as "pxObjClass"
from {class:My-Int-TestClass} as test_tbl_inner
where test_tbl_inner.ID=test_tbl_outer.ID
FOR XML RAW('pagedata'), TYPE, ELEMENTS
) as pzPVStream
from {class:My-Int-TestClass} as test_tbl_outer
This gets an invalid signature error (the SQL query does work directly however), and if I try to shove a signature string onto the column ('PR6d' or previous) I just get a different error regarding headers.
So at this point, I do realize that the pzPVstream is not stored as xml but as some sort of packed & compressed string. Is there a way for me to create a valid pzPVstream on the fly? Maybe something similar to what pr_read_from_stream does but in reverse?
The use case is that we'd like to pull a whole mess of data from an existing data warehouse. And it would be nice if we could pull all the multi-value data (many,many joins deep) over in one trip. We are not too concerned with the size of this object as we plan on pulling this data one way or another.
The pzPvStream is a compressed blob and it resonates a work object. It is compressed and stored as a single column in a table.
When it is read using obj-browse or obj-open activities, the blob is decompressed and all the encompassed properties are mapped to the clipboard.
This value has a proprietary format; the values are obfuscated.
I'm following a tutorial where they explain how to add a Dataset to your ASP.NET web application and how to add a parameter to a SQL query. But it's not really working for me the way they are doing it in the tutorial.
I've added a Dataset to my App_Code folder. In the dataset i made a connection to a database in SQL Server. Now i can get data from my database by giving the dataset a SQL query. In the tutorial they do something like this:
SELECT TOP 20 [ProductID]
,[Name]
,[ProductNumber]
,[MakeFlag]
,[FinishedGoodsFlag]
,[Color]
,[SafetyStockLevel]
FROM [Production].[Product]
WHERE (Color = :Color)
The point in this example is the :Color part. That is how they let it know where to add the parameter. But when i use this query in my Dataset it gives me a warning:
Error in WHERE clause near ':'. Unable to parse query text.
After that he is able to actually add a parameter to the Dataset through the Properties window and test preview his data. That doesn't work for me since it already starts to complain when i add my query.
What can i do to solve this problem?
Parameters in Sql-Server have a # in front:
WHERE (Color = #Color)
