Question

I have 1500 rows and i want to update all the rows with a constant value(Varchar)

This can done using UPDATE command in Mysql but i am not sure about the syntax for that..

Thanks in advance.

Answer 1

UPDATE yourTable SET yourField="yourValue"

If you want to update only some fields, not all, add a WHERE clause:

UPDATE yourTable SET yourField="yourValue" WHERE id=1

You should consult the MySQL Docs before asking basic syntax questions.
