![]() ![]() $ mysql -u username -p"password" tutorialsDB < testDB. The final step is to import old database into new database as follwing: $ mysqladmin -u username -p"password" create tutorialsDB Next step is to create our new database using mysqladmin prompt command as follows: The -R is required to tell mysqldump to copy stored procedures and functions along with the normal data from the database. We are using the -p flag immediately followed by our password to connect to the database with no space between. $ mysqldump -u username -p"password" -R testDB > testDB.sql This operation will be performed from command line and will require a database user name and password, preferably admin privilege. So first we will dump it in a simple SQL file using MySQL mysqldump command. This is three step process which we will follow in this tutorial: Step 1 - Dump Old DatabaseĬonsider you want to rename testDB database to tutorialsDB. ![]() If you are willing to rename a database name in MySQL, then simple way is to dump the complete database in an SQL file and then re-import it into a new database. Next section will show you a work around to rename your MySQL database. There used to be a simple RENAME DATABASE command in older versions of MySQL which was intended to rename database but RENAME DATABASE command has been removed from all newer versions to avoid security risks. ![]() ![]() Stored Procedures, Views, Triggers will be lost when using this command.Now, issue the following command to rename the database testDB to tutorialsDB: The problem is that only DATA are kept with this command. We not support it and have not decided if we will ever do. However 'rename database' is implemented in MySQL in the 5.1 tree. Probably it is safest NOT to use BULK INSERTS at all! Though that would increment the time for restore. Be sure to use a 'Bulk Insert' setting that you know works with the server configuration. And if you have ONE DB ONLY at a webhost (typical 'personal' subscription plan) you will need to backup, drop current DB, change 'use'-stmt and import. The dollar sign can still be used as the leading. This includes such names used with qualifiers (see Section 9.2.2, Identifier Qualifiers). Don't be confused - it works with two DBs on the same host as well! When it is done you can drop the old one.īut no matter how you do it involves copying all data, and it will take a lot of time with big DBs. Beginning with MySQL 8.0.32, use of the dollar sign as the first character in the unquoted name of a database, table, view, column, stored program, or alias is deprecated and produces a warning. This command includes the minimum settings needed to connect to the database. shbat start -db postgres -db-url-host mypostgres -db-username myuser -db-password changeme. However, you can copy your database to a new one with a new name in different ways with SQLyog:ġ) make a backup with SQLyog and change the 'use' SQL-statement in the dump-file to new DB-name before importing.Ģ) create a new empty database and "copy DB to other host" using SQLyog. Start the server and set the basic options to configure a database. You may be left with nothing then! So for security reasons a 'rename DB' is not available. Changing both system tables and filenames is not without problems (not secure) in case of a server crash in between. The reason is that the database names exist not only in MySQL tables but as filenames in the filesystem as well. MySQL Database MySQL Create DB MySQL Drop DB MySQL Create Table MySQL. Directly changing database names is not possible! It is not a restriction with SQLyog, but with MySQL itself. ![]()
