Find single value and replace with dynamic value in table

 
0
 

i have no idea where to start but;
i'm looking for a way to change all emails from suppliers@test.domain.com to title@test.domain.com in a MySQL DB.

DB Name: simons_directory
Table: listing
Fields: title, email

caveats - title has words with spaces, if possible to remove the spaces so "My Business Name" would equal "MyBusinessName"

any ideas?

can be in a MySQL statement or php code.

YOU need to run update query in mysql
to update emails

update listing set email='title@test.domain.com' where 
email='suppliers@test.domain.com'

Be carefull before using following query. it will set title to title without spaces in all records, so better you add new column say title_wo_space, then use following query

update listing set title_wo_space=replace(title,' ','')

thank you for your very quick reply, but i want to change it to $title@test.domain.com where $title reflects the values in the 'title' field, making sure the spaces are removed from the $title email.

so for example:
title: Bobs Cleaning
email: BobsCleaning@test.domain.com (changed from suppliers@test.domain.com

UPDATE listing SET email=SELECT CONCAT(REPLACE(title, ' ','' ) , SUBSTR(email, INSTR(email,  '@' ) ) )

For more complicated pattern match and replacement you could also dump the database to a file, run it through sed and import it again.

run it through sed

Hi smantscheff, I do not understand this, please explain.

i think he means u export the SQL file and use sed and use it to make the changes then re-import the sql file.

UPDATE listing SET email=SELECT CONCAT(REPLACE(title, ' ','' ) , SUBSTR(email, INSTR(email,  '@' ) ) )

i dont think that will do it, keep in mind it dont want to alter any other accounts just ones with supplier@. i think i might have to do it the SED way with regex.

you can use where condition to filter records

UPDATE listing SET email=SELECT CONCAT(REPLACE(title, ' ','' ) , SUBSTR(email, INSTR(email,  '@' ) ) ) where email like 'supplier@%'

If you are not comfortable with sed, try EditPad Pro which has a very comfortable search and replace interface for RegEx's. It's PREG style, so that you can even use the ungreedy modifier, which can make operations quite simple. Just export the database to a textfile, load it in EditPad, do your replacements and re-import it.

i tried your example and get the error below

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT CONCAT(REPLACE(title, ' ','' ) , SUBSTR(email, INSTR(email, '@' ) ) ) WHE' at line 1

I have PowerGREP for windows, but i dont see how regex can find an email and replace it with a seperate variable for every line.
REGEX has always been a pitfall for me.

That cannot be that much of a problem. Show some actual testdata.

But urtrivedi already gave you the solution for that.
What's wrong with

UPDATE listing 
SET email=concat( 
  replace(title,' ', ''),
  substr( email, locate( '@', email ))
);

How do you feed those queries into mysql? The error you've got seems to indicate that you are using the wrong tools.
Also let me remark that the listings table shows a very poor design.

There was select keyword near = sign, thats why you might have got error, following should work.

UPDATE listing SET email= CONCAT(REPLACE(title, ' ','' ) , SUBSTR(email, INSTR(email,  '@' ) ) ) WHERE email LIKE 'supplier@%'

ok with the new code i ran it, says below:

0 row(s) affected. ( Query took 1.2118 sec )

and nothing was changed.

I use phpmyadmin to execute the code.
i know the code is bad, its from software we bought and have no choice over the matter.

make supplier plural add 's' before @ sign
'suppliers@%'
