I have a custom database and there is a word http:// that I want to change to https:// with a query in phpmyadmin or using CLI. What update command can I use to find and replace this text in all tables of my current database?

If you want to edit from all tables, best way is to take the dump and then find/replace and upload it back.

Honestly I used this way in the past and I got error after I restored it back Phpmyadmin, I don't know why but I would run updates via Mysql query, that seems safer and I used succeeded with running queries.

I used this command

Code:
UPDATE Table_name SET field = replace(field, "old_data", "new_data");
but It will only work on a table, I wanted to run queries on all tables.

I agree with Allen, perform a database dump, and then do the search/replace on that dump and re-import.

So to dump MySQL (assuming linux) lets go ahead and make two, one we're going to mess with, the other is a backup incase something goes wrong.
Code:
mysqldump -u username -P database_name -> /path/to/dump/file.sql
mysqldump -u username -P database_name -> /path/to/dump/full_backup.sql
Next you can use sed to search and replace.

Code:
sed -i 's/http:\/\//https:\/\//g' /path/to/dump/file.sql
Finally, re-import the database.

Code:
mysql -u username -P databae_name < /path/to/dump/file.sql
That autta do the trick. I you run into any issues lemme know but always take backups first :)

I afraid I have not got sed installed on my VPS. what is it?

Code:
sed -i 's/http:\/\//https:\/\//g' /path/to/dump/file.sql
What is -i, s, g parameter in this command?

Is it easier for me to download the db file to Windows and replace http by https via a text editor as notepad++?

Thanks

Hello,
You can use the search and replace feature of phpmyadmin. At first une search to find tables with the word http://, and then go into the table and use search and replace.
