Hello All,

I have a table having Blob datatype having more than 1000 records. I use Phpmyadmin for mysql maintenance.

Phpmyadmin does not display or edit  columns of Blob datatypes? Now i have to edit a blob field how do i do that in phpmyadmin?

i thought changing columns of 'blob'  datatype to text or char would atleast help me in browsing/editing the data .....but was unable to change datatypes :(

following was the error when i tried to change blob datatype to char datatype

(mysql#) alter table electrical change address address text character set utf8;

ERROR 3 (HY000): Error writing file './property/#sql-b0d_5.frm' (Errcode: 28)

Plz help me out.

Thx in advance.

    What kind of data do you have in blob field?

    What if you do a backup copy of your database, structure and data, this should give you a text file, then edit the text file and reload to the db. Use the export tab.

    Thx  for responding gamebits!

    I sorted out the problem ...its rather a simple solution ..... I just changed the data type from Blob to text in the phpmyadmin interface..
    (when i tried to change from MySQL shell i faced problem but same datatye change from PHPMyAdmin worked flawlessly!)
