Hello,

I need to search a string in a mysql text field that could contains newlines chars. Using the standard LIKE operator it does not work because the string searched is different from the text field as it contains newlines.

Here is an example:
select id from fb_posts where message like '%Fineco App. Tutti i servizi, in tutti i device. Da dove preferite collegarvi? https://welcome.fineco.it/bancaonline/extra/fineco-app%'

the string could not be found because the text field is:

Fineco App. Tutti i servizi, in tutti i device.
Da dove preferite collegarvi?

https://welcome.fineco.it/bancaonline/extra/fineco-app

So I think there should be e method to search removing newline chars.

thank you

Try
select id from fb_posts where message like '%Fineco App. Tutti i servizi, in tutti i device.\n Da dove preferite collegarvi? https://welcome.fineco.it/bancaonline/extra/fineco-app%'

Open in new window

or
select id from fb_posts where message like '%Fineco App. Tutti i servizi, in tutti i device.\r\n Da dove preferite collegarvi? https://welcome.fineco.it/bancaonline/extra/fineco-app%'

Open in new window

if the text is from Windows.

HTH,
Dan
