Question

I need to copy a table from one database to another. This will be a cronjob. Which one is the best way to do it? PHP script or Shell Script. The problem with PHP, both databases has different usernames and passwords so I can’t do it like this.

CREATE TABLE db1.table1 SELECT * FROM db2.table1

Should I just connect first DB get all records and insert all to new database using WHILE loop or there is a better way?

I prefer a shell script to do this instead of PHP script.

Thanks

Answer 1

I’d dump it. Much less complicated than anything PHP based.

mysqldump -u user1 -ppassword1 databasename > dump.sql
mysql -u user2 -ppassword2 databasename < dump.sql

MySQL reference: 4.5.4. mysqldump — A Database Backup Program
