Re: Convert BLOB into String using SQL

Hi Neils,

No luck with INTERPRET, it is doing the job what CAST is doing.

For my case I am not getting the expected result.

I don't think we have a simple query to view the BLOB data from the file.

Regards,
Suren

Hi Birgitta,

I am using SQL Session in 5250 Emulator to view the data.

For now I am using the following query to view the JSON Data stored in
the
file which is working fine
SELECT CAST(SYSTOOLS.BSON2JSON(DATA) AS VARCHAR(1000)) FROM BLOBFILE

I need to find a way to view the normal string (Not a JSON Data) which is
stored in BLOB Field.

Thanks for your hint, for changing the CCSID. I will try some queries to
translate the CCSID.

Regards,
Suren

BLOB is a binary string, that's why you see the hex data.

How do you view the data? With ACS?
If so you need to set the Translate CCSID 65535 in your connection
(Translation --> Translate CCSID 65535), then the Binary data is
displayed
with your job's CCSID.

Mit freundlichen Grüßen / Best regards

Subject: Reg: Convert BLOB into String using SQL

Hi All,

I created a file with BLOB Field, where I am inserting data into a file
using two options, 1) for a valid JSON data I used JSON2BSON, 2) for a
normal string data I used BINARY(DATA).

When I try to view the data using SQL, I can see the valid JSON data
using
CAST(SYSTOOLS.BSON2JSON(DATA) AS VARCHAR(1000)), but for a normal
string
data I am not able to view the data in character string.

Any suggestions on how to view the normal string data which is stored
in
BLOB Field using SQL?

Regards,
Suren
