Splunk DB Connect 2: How to fetch and read XML data from BLOB and CLOB fields in MS SQL and Oracle database tables?

Engager

Hi,

We're using Splunk DB Connect 2 on top of our DB (MS SQL server and Oracle DB). In most of our tables, we've BLOB and CLOB fields that contain XML.
I would like to know how we can fetch and read the actual data from these fields?

Thank you in advance,
Moshe

So far this is pretty ugly, but only substrings are working for me to extract from a clob.
My system does not understand the XMLType data type. (DBX 3, Java 8 and Oracle JDBC driver for 18C)
This runs...
select DBMSLOB.substr(a.MyOBJ, 3000 , 1) as MyXML1, DBMSLOB.substr(a.MyOBJ, 3000 , 3000) as MyXML2 from MyTableWithClob a

The answer to this question is more about SQL than Splunk. Here is what I do in Oracle, but you'll want to ask your DBA (I'm not a DBA by far).

SELECT x.object_value.getCLOBVal() FROM XML_TABLE x;

Googling around, here's another way to skin that cat.

select
XMLType( BLOB_COLUMN,
         1 /* this is your character set ID.
                   1 == USASCII */
       ) as XML
from my_table;

You need to use SQL to convert it to a char field

E.g

Select tochar(clobfield) from table
