Mysqldump only tables with certain prefix / Mysqldump wildcards?

阅读更多关于 Mysqldump only tables with certain prefix / Mysqldump wildcards?

问题 I have this huge, messy database I am cleaning up. It houses 500+ tables, which is the result of combining Magento Enterprise with Joomla in one single DB. To make things worse, there is a set of 70+ Joomla tables that are not in use at all. These are all prefixed with bak_ . Just deleting these bak_ tables will be easy, but I want to 'bak' them up first (see what I did there?). In my mind I can picture a command like this: mysqldump -u username -p mydatabase bak_* But this doesn't work. What

mysqldump - Export structure only without autoincrement

阅读更多关于 mysqldump - Export structure only without autoincrement

问题 I have a MySQL database and I am trying to find a way to export its structure only, without the auto increment values. mysqldump --no-data would almost do the job, but it keeps the auto_increment values. Is there any way to do it without using PHPMyAdmin (that I know it can do it)? 回答1: You can do this : mysqldump -u root -p -h <db-host> --opt <db-name> -d --single-transaction | sed 's/ AUTO_INCREMENT=[0-9]*\b//' > <filename>.sql As mentioned by others, If you want sed to works properly, add

dump all mysql tables into separate files automagically?

阅读更多关于 dump all mysql tables into separate files automagically?

I'd like to get dumps of each mysql table into separate files. The manual indicates that the syntax for this is mysqldump [options] db_name [tbl_name ...] Which indicates that you know the table names before hand. I could set up the script that knows each table name now, but say I add a new table down the road and forget to update the dump script. Then I'm missing dumps for one or more table. Is there a way to automagically dump each existing table into a separate file? Or am I going to have to do some script-fu; query the database, get all the table names, and dump them by name. If I go the

阅读更多关于 Restore the mysql database from .frm files

I have dumped all my tables everyweek to got the backup. But later I understand that it is only storing the .frm file of the table. It is not showing .MYD and .MYI files of a table.

Import MySQL database into a MS SQL Server

阅读更多关于 Import MySQL database into a MS SQL Server

I have a .sql file from a MySQL dump containing tables, definitions and data to be inserted in these tables. How can I convert this database represented in the dump file to a MS SQL Server database?

It also got some command line interface (in addition to GUI) so theoretically it can be integrated into some batch load process.
