我想在整个数据库中进行查找和替换，而不仅仅是一个表.
我如何修改下面的脚本才能工作？
update [table_name] set [field_name] = replace([field_name],'[string_to_find]','[string_to_replace]');
我用的是asterix吗？
update * set [field_name] = replace([field_name],'[string_to_find]','[string_to_replace]');
sqldump到文本文件，查找/替换，重新导入sqldump.
Dump the database to a text file
mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
Restore the database after you have made changes to it.
mysql -u root -p[root_password] [database_name] < dumpfilename.sql
