MySQL DUMP作为CSV

Question

I've looked around and nothing seems to work:

$file = '/path/to/file.csv';
$cmd = 'mysqldump DATABASE TABLE > '.$file.' --host=localhost --user=USER --password=PASS';
$cmd .= ' --lock-tables=false --no-create-info --tab=/tmp --fields-terminated-by=\',\'';
exec($cmd);

Everything I try creates an empty CSV file. Any ideas? Thanks much.

Answer 1

I found a way to accomplish this using mysql via command line --

        $file = '/path/to/file.csv';
        if(is_file($file))
            unlink($file);      
        $sql = 'SELECT * FROM database.table';
        $cmd = 'mysql --host=localhost --user=USER --password=PASS --quick -e \''.$sql.'\' > '.$file;
        exec($cmd);

Try SQLYog, works like a charm.

Here is a link to a download of the free community version

Then all you have to do is right click on the table in question, and go export, and select CSV etc...

If your looking for the code how to do it, then look in the history tab after you export the table and see what code was executed.

Answer 3

what happens when you do: mysqldump DATABASE TABLE > /path/to/file.csv [snipped the rest of the command] from the command line?

Does it work?

Your last line try:

$cmd .= " --lock-tables=false --no-create-info --tab=/tmp --fields-terminated-by=','";

the single quotes don't get escaped in a single quoted string.

The > '.$file.' redirection should be the last (or first) part of the command
