How do I convert BLOB into VARCHAR in MySQL?

Question

It is in a shared host and I access with Navicat. I have field with BLOB and I want to convert it into VARCHAR. I've tried in the design screen but everything was lost. I backed up.

Answer 1

try using this, I found it some time ago, you can convert it to char, not to Varchar2 or Varchar, haven't test it yet. Try:

CAST(a.ar_options AS CHAR(10000) CHARACTER SET utf8)

MySQL treat data unique. Hence there is a difference between Blob and Text. Text simply means a text string stored as original, not in binary, whereas a blob is a text string stored as a binary.

Answer 2

try with the below query

alter table table_name change field_name field_name VARCHAR(1000);

Answer 3

I found this of MySQL's Website if you are trying to change your column to a different data type and keep the new data type in the database. Works great for what I need!

ALTER TABLE table_name CHANGE col col1 varchar(100)
