Mysql replace row if value = something

I want to edit in 'videos' table, if 'category' column has the value set to 'Music' then开发者_Go百科 replace it with the value '1'.

How can i do this?

I'm a bit confused as to what you're trying to accomplish. Is 'category' a column that is currently set to 'Music' for some row, and you want to set that to 1? If so:

update videos set category = 1 where category = 'Music'

UPDATE videos
    SET category = '1'
    WHERE category = 'Music'

update [table_name] set [field_name] = replace([field_name],'[string_to_find]','[string_to_replace]');

err

update videos set category="1" where category="Music"

Take a look at the mysql docs, they are really good with explanations and examples.

You want to replace the category with '1'?

update videos
set
  category = '1'
where
  category = 'Music'

Most probably the category your are referring to is a column, and not a row. If that is true then this solution is apt:

UPDATE videos SET category = '1' WHERE category = 'Music'
