Question

I want to insert rows from a specific table in a database to another database with a bash script. The two databases are on different servers. How can I do that?

I want something like this:

INSERT INTO db1.table1(row1, row2) SELECT row1,row2 FROM db2.table2;

But the databases are on different servers.

Thank you.

I think you need to use ssh to execute a remote command and mysldump to get the rows from the remote db and mysql to insert the row to the local db.

ssh <remoteuser>@<remoteServer> mysqldump -t -u <remoteDbUser> -p<remoteDbPass> <remoteDbName> <remoteDbTable> -w<whereCondition> | mysql -u <localDbUser> -p<localDbPass> <localDbName>

Pay attenction that:

1. there is no space between -p and the password.
2. The -t option avoid the CREATE TABLE sql instruction

Use the man page for more information about the mysqldump command.
