Question

I am making some big changes to my database, so I need to replace a lot of text with some new text, but only when a certain word exist.

  Table
*-----------------------------------------------*
|    id    |    name   |    adress   |   town   |
*-----------------------------------------------*

I have a table like this. I want to replace “adress” and “town” in every row of the table, where “town = new york” (for example).

So every time the text “new york” occurs in “town”, both adress and town should be replaced with something else. Only one time- when i run the script.

Can anyone help me with this? I imagine i could use preg match and replace function from PHP in some way do to this, or can it be done purely with a SQL command?

Thank you guys

UPDATE theTable
SET name = 'xxx',
    adress = 'xxx'
WHERE town LIKE '%new york%' 

Or, WHERE UPPER(town) like UPPER('%new york%') to be case insensitive.
