Sometimes it’s necessary fix data on the database.
I had to fix on a Microsoft database:
/* MSSQL syntax */ update table_links set url = Replace(url, 'www.link.it/web3', 'www.link.it/web') where url <>''
I had to fix on a MySQL database:
/* MySQL syntax is the same! */ UPDATE table_links SET url =REPLACE(url, '&', '&') where url<>''
The syntax is the same.
