String is not BLOB it is CLOB.
Or is this a BLOB that contains strings? In this case why not using CLOB instead?

Post something we can work with (in addition to answer to BlackSwan's question).

SELECT command?
I don't see any SELECT statement from you.
We don't know the table name or any column names.

What should be result when BLOB contain below?

1 "ID10T" PIN_FLD_ERROR_CODE STR [0] "20321"

How can you get this from a BLOB as a BLOB is BINARY data and so NOT characters?
You MUST post something we can reproduce.
Copy and paste what you did (Please use [code] tags).

Michael,

I am new to oracle database. Sorry if I am not clear on my question.

Below data I am getting in of the table and they storing below data in one of the BLOB column for one record.

0 PIN_FLD_POID POID [0] 0.0.0.1 /account 1 0
0 PIN_FLD_STATUS ENUM [0] 0
0 PIN_FLD_PRODUCT_NAME STR [0] "PNRS-10-DHCP-10K"
0 WBX_FLD_ITEM_ID STR [0] "348011798"
0 WBX_FLD_ITEM_DESC STR [0] "PNR R10 DHCP Upgrades 3yr - 10,000 IP Leases"
0 PIN_FLD_ERROR_INFO ARRAY [0] allocated 20, used 3
1 PIN_FLD_NAME STR [0] ""
1 PIN_FLD_DESCR STR [0] "Product: PNRS-10-DHCP-10K\nPermitted: Subscription"
1 PIN_FLD_ERROR_CODE STR [0] "20321"

And my work to get the error code (i.e. 20321) out of this data..

Hope fully you understood.

Once again, how do you get it?
New or not to Oracle you should know how you get this.
Just copy and paste what you do (before read How to use [code] tags and make your code easier to read).
Without this, I can't help you.

So forgetting about the BLOB stuff and assuming these are just string data and you want what's between " in the row that contains 'PIN_FLD_ERROR_CODE' then it is something like:
select regexp_substr(string,'"([^"]*)',1,1,'',1) 
from t
where string like '%PIN_FLD_ERROR_CODE%'
