mysqldump

问题 I'm just trying to perform a mysqldump and have it scheduled. I'm using RHEL 5 and have added it to the crontab as shown below: 22 13 * * * root mysqldump --user=root --password=12345 mysqldb > /var/backups/mysqldb date +%d%m .sql The .sql file never ended up in the backups folder. I even attempted to run this command line and it worked fine which tells me its something to do with the cron. Furthermore, I added a simple comand like "ls" and the output to the same directory and it worked fine.

问题 I'm trying to dump some of my tables if the prefix of theme is matching a given sub string using php. Trying to use php's system did not bring any result in sense the dump file was not created. I thought to use the command line function exec to achieve my result and I was making the following exec('E:/xampp/mysql/bin/mysqldump '. $dbname .' -h '. $this->host .' -u ' .$this->user . ' $(E:/xampp/mysql/bin/mysql -u '. $this->user . ' -p ' . $dbname .' -Bse "show tables like \'wp_dev%\'")> mydb

However, when in Access 2003, I go to file menu to Get external data and browse the text file, it just don't do anything after I select the file. I have tried loading through

问题 I have a mysql database with 10 tables and need to drop and repopulate the database to run some performance tests. Using mysqldump, I can dump out the data. What steps should I follow next, to clear the database, and re-import? Will need to run this for different sizes of the database (i.e. tables with different number of rows) to calculate the db performance, so I need to make sure these steps can be replicated. 回答1: You might want to look at the options on mysqldump such as --add-drop

问题 I'm trying to import a very large MySQL dump file into a new MySQL server. However, after a certain point, it seems to bog down. I'm about 250M rows in, and it's taking over 10-12 seconds to run even a single line of the dump. It seems to hang on "update". Am I missing something I should do to make this import go faster? It's a pretty beefy server so I don't think it's the I/O.. 回答1: What seemed to work for me with a 'beefy' server, was splitting the file into several smaller and importing
