Hi Shrini,

Easy way would be : If you have the existing html then just change the
contents of that html file and edit the blob field and update this file. I
have tried and it works.

To read the contents try out this query :
SELECT SUBSTRING(blobfield FROM 1 FOR 32000) FROM tablename;
This returns the string of that blob content.

Another way would be using fbsql_read_blob php function. More :
