Mysqldump Access Denied When Selecting The Database
TABLES to the user you are using to take the dump $ mysql -u root -p mysql> GRANT SELECT,LOCK TABLES ON DBNAME.* TO 'username'@'localhost'; Reading through the man pages, these pasages sheld some light on the issue at hand: mysqldump requires at least the SELECT privilege for dumped tables, SHOW VIEW for dumped views, TRIGGER for dumped triggers, and LOCK TABLES if the --single-transaction option is not used. Certain error 1044 (42000): access denied for user 'root'@'localhost' to database 'information_schema' options might require other privileges as noted in the option descriptions. For each dumped database, lock all tables to be dumped before dumping them. The tables are locked with READ LOCAL to permit concurrent inserts in the case of MyISAM tables. For transactional tables such as InnoDB, --single-transaction is a much better option than --lock-tables because it does not need to lock the tables at all. Because --lock-tables locks tables for each database separately, this option does not guarantee that the tables in the dump file are logically consistent between databases. Tables in different databases may be dumped in completely different states.

Got error: 1044: Access denied for user x@y http://bytefreaks.net/programming-2/mysqldump-got-error-1044-access-denied-for-user-usernameip-to-database-db-when-doing-lock-tables to database z when using LOCK TABLES To solve this problem, either ask you administrator to grant you the lock privileges, or use the following command instead. mysqldump -u access denied username -p database --single-transaction >dump.sql This is the help entry for the keyword --single-transaction Creates a consistent snapshot by dumping all tables in a single transaction. Works ONLY for tables stored in storage engines which support multiversioning (currently access denied for only InnoDB does); the dump is NOT guaranteed to be consistent for other storage engines. While a --single-transaction dump is in process, to ensure a valid dump file (correct table contents and binary log position), no other connection should use the following statements: ALTER TABLE, DROP TABLE, RENAME TABLE, TRUNCATE TABLE, as consistent snapshot is not isolated from them. Option automatically turns off --lock-tables.

The ‘LOCK TABLES' right gives you access to the command LOCK that can be used to emulate transactions or to get more speed when updating tables by preventing other sessions from modifying the locked tables. To mitigate the problem, use the --single-transaction option as follows mysqldump -h "mysql.example.com" -u "username" -p"password" --single-transaction db table_A table_B Documentation: · --single-transaction This option sets the transaction isolation mode to REPEATABLE READ and sends a START TRANSACTION SQL statement to the server before dumping data. It is useful only with transactional tables such as InnoDB, because then it dumps the consistent state of the database at the time when START TRANSACTION was issued without blocking any applications. When using this option, you should keep in mind that only InnoDB tables are dumped in a consistent state. For example, any MyISAM or MEMORY tables dumped while using this option may still change state. While a --single-transaction dump is in process, to ensure a valid dump file (correct table contents and binary log coordinates), no other connection should use the following statements: ALTE
