Reading BLOB data from FCI_ATTACHMENT_BLOB

Hi,

I need to read some Big Text data from FCI_Attachment table field FILE_DATA. I want to create a query which can display all the Big text data in a column.

I tried using SUBSTR( CAST(FCI_ATTACHMENT_BLOB.FILE_DATA AS VARCHAR(20000)),1)  but it returns binary data.

How do I retrieve the actual text instead of binary information in the query?

Also, what are the options if I want to place each of the bigtext record as separate flat files in a folder location.

Can this be achieved via script?

Appreciate any helpful pointers.

Thanks,

Priyanka
