Answer 1

You may want to use 'SELECT ... INTO OUTFILE' and 'LOAD DATA INFILE INTO TABLE' commands.

Edit: Elaboration...

Given the table structures:

CREATE TABLE my_local_table (
    id int NOT NULL auto_increment PRIMARY KEY,
    data varchar(20),
    created_on datetime);

CREATE TABLE server_table (
    id int NOT NULL auto_increment PRIMARY KEY,
    data varchar(20),
    created_on datetime,
    local_id int);

And some bogus data:

INSERT INTO my_local_table (data, created_on) VALUES ('test', now()), ('test2', now());

You would use the following commands:

SELECT id, data, created_on 
    FROM my_local_table
    WHERE created_on >= '2011-08-18'
    INTO OUTFILE '/tmp/t.txt';

-- (and on the server)
LOAD DATA LOCAL INFILE '/tmp/t.txt'
    INTO TABLE server_table
    (local_id, data, created_on);

To automate the two, you can use a bash script / batch file calling mysql connecting first to the local server using the first statement, then to the remote server executing the second.

mysql -e 'SELECT....';
mysql -h remote_server -e 'LOAD DATA...';

Answer 2

You want to set up replication between the server and your local machine -- see the reference documentation for details.
