Finding and Replacing Data in an Entire MySQL Database
Developers seeking to replace strings across an entire MySQL database may encounter limitations with table-specific find and replace methods. Here's how to overcome this challenge:
Using an asterisk () in the "update " syntax will not alter the contents of the entire database. Instead, consider utilizing a more robust approach:
Dump and Replace (Using a Text File)
Dump the Database to a Text File:
mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
Re-Import the Dumped Database:
mysql -u root -p[root_password] [database_name] < dumpfilename.sql
This method allows for comprehensive find and replace operations across all database tables. Remember to back up your database before proceeding with any alterations.
