HOW CAN WE TAKE A BACKUP OF A MYSQL TABLE AND HOW CAN WE RESTORE IT?
PHP Interview Questions and Answers
(Continued from previous question...)
HOW CAN WE TAKE A BACKUP OF A MYSQL TABLE AND HOW CAN WE RESTORE IT?
Answer 1:
Create a full backup of your database: shell> mysqldump tab=/path/to/some/dir opt db_name
Or: shell> mysqlhotcopy db_name /path/to/some/dir
The full backup file is just a set of SQL statements, so restoring it is very easy:
shell> mysql "."Executed";
Answer 2:
To backup: BACKUP TABLE tbl_name TO /path/to/backup/directory
’
To restore: RESTORE TABLE tbl_name FROM /path/to/backup/directory
mysqldump: Dumping Table Structure and Data
Utility to dump a database or a collection of database for backup or
for transferring the data to another SQL server (not necessarily a
MySQL server). The dump will contain SQL statements to create the table and/or populate the table.
-t, no-create-info
Don't write table creation information (the CREATE TABLE statement).
-d, no-data
Don't write any row information for the table. This is very useful if you just want to get a dump of the structure for a table!
