Why I cannot alter my schema name from the MYSQL Workbench? Am i missing something? :(
As you can the name is dissabled
There is no RENAME available for schema names. You will have to export the schema, then import with a new database name.
This is a limitation of the MySQL server itself.
Actually, you can rename database name very easily,
go to the top menu -> Database -> reverse engineering, select your database and keep go further until you get the er diagram of your database,
after the there is an area called Catalog Area under that you can see your database name, right click on that and select edit schema. and change your database name
now again go to the top menu -> database -> forward engineering and completed the database engineering using the wizard.
I can't imagine that anyone is still using version 5.5, but here is the procedure I followed in version 8. If you do have an older/newer version this may still work.
Connect to the database.
Open the Database menu and choose Migration Wizard.
Start Migration.
Both source and target will be the current MySQL server.
Select the schema you want to rename.
For Source Objects make sure all the tables are selected.
Click Next and you will see a message that the source and target are the same.
Now you should see a "Manual Editing" step.
Under the Target Object column, click on the database name and change it.
Now you can click next all the way through.
Once finished you will have a newly renamed schema.
Currently my database has no indexes, stored procedures, etc. You will
want to confirm all related objects are migrated as well before
dropping the old database.
Gavin is right, but if your server have phpMyAdmin, you can use it to rename your database (schema):
Go to your phpMyAdmin URL. Default is http://yourdomain.com/phpMyAdmin/
If prompted, enter your database username and password.
Click on "Operations" tab.
Under "Rename database to:" write your new database name.
Click "Go" button.
If prompted, click "OK".
After some seconds, depending on your database content, you will have your database renamed.
What phpMyAdmin is actually doing is create a new database with your new name, import the content from your current database and delete your current database.

I deleted records in a MySQL table two days ago. Can you please help me to get back these records. I don't know how to repair the MySDL table.
Please help me to get back the deleted data and mention some way to create a backup for my MySQL database.
There's no "magical" way to restore deleted data, so :
To create a backup, you simply have to export the whole database in a file. This can be done easily with any database manager. Here is how to do it with PHPMyAdmin :
Click on your database (left pane)
Click on Export (top of the page)
Click on Go for a quick and full export
Keep the generated file in a safe place (ie. not in your website folder)

How do I rename a MySQL database (change schema name)?

How can I change the database name of my database?
I tried to use the rename database command, but on the documents about it it is said that it is dangerous to use. Then what should I need to do to rename my database name?
For example, if I want to rename my database to this.
database1 -> database2?
Follow bellow steps:
shell> mysqldump -hlocalhost -uroot -p database1 > dump.sql
mysql> CREATE DATABASE database2;
shell> mysql -hlocalhost -uroot -p database2 < dump.sql
If you want to drop database1 otherwise leave it.
mysql> DROP DATABASE database1;
Note : shell> denote command prompt and mysql> denote mysql prompt.
I don't think it's possible.
You can use mysqldump to dump the data and then create a schema with your new name and then dump the data into that new database.
Unfortunately, MySQL does not explicitly support that (except for dumping and reloading database again).
From http://dev.mysql.com/doc/refman/5.1/en/rename-database.html:
13.1.32. RENAME DATABASE Syntax
RENAME {DATABASE | SCHEMA} db_name TO new_db_name;
This statement was added in MySQL 5.1.7 but was found to be dangerous and was removed in MySQL 5.1.23. ... Use of this statement could result in loss of database contents, which is why it was removed. Do not use RENAME DATABASE in earlier versions in which it is present.
"As long as two databases are on the same file system, you can use RENAME TABLE to move a table from one database to another"
-- ensure the char set and collate match the existing database.
SHOW VARIABLES LIKE 'character_set_database';
SHOW VARIABLES LIKE 'collation_database';
CREATE DATABASE `database2` DEFAULT CHARACTER SET = `utf8` DEFAULT COLLATE = `utf8_general_ci`;
RENAME TABLE `database1`.`table1` TO `database2`.`table1`;
RENAME TABLE `database1`.`table2` TO `database2`.`table2`;
RENAME TABLE `database1`.`table3` TO `database2`.`table3`;
http://dev.mysql.com/doc/refman/5.7/en/rename-table.html
You can change the database name using MySQL interface.
Go to http://www.hostname.com/phpmyadmin
Go to database which you want to rename. Next, go to the operation tab. There you will find the input field to rename the database.
InnoDB supports RENAME TABLE statement to move table from one database to another. To use it programmatically and rename database with large number of tables, I wrote a couple of procedures to get the job done.
You can check it out here - SQL script #Gist
To use it simply call the renameDatabase procedure.
CALL renameDatabase('old_name', 'new_name');
Tested on MariaDB and should work ideally on all RDBMS using InnoDB transactional engine.
I agree with above answers and tips but there is a way to change database name with phpmyadmin
Renaming the Database
From cPanel, click on phpMyAdmin. (It should open in a new tab.)
Click on the database you wish to rename in the left hand column.
Click on the Operations tab.
Where it says "Rename database to:" enter the new database name.
Click the Go button.
When it asks you to want to create the new database and drop the old database, click OK to proceed. (This is a good time to make sure you spelled the new name correctly.)
Once the operation is complete, click OK when asked if you want to reload the database.
here's the video tutorial:
http://support.hostgator.com/articles/specialized-help/technical/phpmyadmin/how-to-rename-a-database-in-phpmyadmin
Another way to rename the database or taking an image of the database is by using the reverse engineering option in the database tab. It will create an ER diagram for the database. Rename the schema there.
After that, go to the File menu and go to export and forward engineer the database.
Then you can import the database.
Sequel Ace database client have a rename database functionality. Select the database you would like to edit and click Database in the menu and then click Rename Database from the dropdown. Rename the database and ckick rename. Done!
After much aggravation this is what I have found to work"simply".
First thing, I am using MYSQL Workbench and the import would not work as it should, as the import dump file would always revert to the original schema name.
I spent several hours trying every thing to no avail,all for a spelling error.
I solved the issue by opening one of the .sql dump files in notebook and hand editing the typo's of the schema name, take care to rename all instances schema name has three in the beginning, save the file and then import. this worked perfectly for me and hope that it will help others looking for the simple answer to changing database names/schema names.
One more tip that I have found true, when programs do not do as they should go to the "source" literally find the source code.
Hope this helps someone
Low rep so they wont let me comment on the prior/post answer(it keeps changing rank or position), so I added it here. reverse engineering will work fine as long as there is no data in the sever table. if data exists and you try to update the server after the name change it will either pull an error or just create a new database/schema with no data, I know I tried ten times to no avail.
The above works simply and avoids headaches, as one can review the SQL code for other errors if any or change table names or creation data.
the .sql file is just a compiled SQL code so in theory one could copy and add it through PHP or the script console of the database management tool.
You can use below command
alter database Testing modify name=LearningSQL;
Old Database Name = Testing,
New Database Name = LearningSQL
Go to data directory and try this:
mv database1 database2
It works for me on a 900 MB database size.
Try:
RENAME database1 TO database2;
How to take database backup using MySQL Workbench? Can we take backup in the following ways-
Backup file(.sql) contains both Create Table statements and Insert into Table Statements
Backup file(.sql) contains only Create Table Statements, not Insert into Table statements for all tables
Backup file(.sql) contains only Insert into Table Statements, not Create Table statements for all tables
For Workbench 6.0
Open MySql workbench.
To take database backup you need to create New Server Instance(If not available) within Server Administration.
Steps to Create New Server Instance:
Select New Server Instance option within Server Administrator.
Provide connection details.
After creating new server instance , it will be available in Server Administration list. Double click on Server instance you have created OR Click on Manage Import/Export option and Select Server Instance.
Now, From DATA EXPORT/RESTORE select DATA EXPORT option,Select Schema and Schema Object for backup.
You can take generate backup file in different way as given below-
Q.1) Backup file(.sql) contains both Create Table statements and Insert into Table Statements
ANS:
Select Start Export Option
Q.2) Backup file(.sql) contains only Create Table Statements, not Insert into Table statements for all tables
ANS:
Select Skip Table Data(no-data) option
Select Start Export Option
Q.3) Backup file(.sql) contains only Insert into Table Statements, not Create Table statements for all tables
ANS:
Select Advance Option Tab, Within Tables Panel- select no-create info-Do not write CREATE TABLE statement that re-create each dumped table option.
Select Start Export Option
For Workbench 6.3
Click on Management tab at left side in Navigator Panel
Click on Data Export Option
Select Schema
Select Tables
Select required option from dropdown below the tables list as per your requirement
Select Include Create schema checkbox
Click on Advance option
Select Complete insert checkbox in Inserts Panel
Start Export
For Workbench 8.0
Go to Server tab
Go to Database Export
This opens up something like this
Select the schema to export in the Tables to export
Click on Export to Self-Contained file
Check if Advanced Options... are exactly as you want the export
Click the button Start Export
Sever > Data Export
Select database, and start export
On ‘HOME’ page -- > select 'Manage Import / Export' under 'Server Administration'
A box comes up... choose which server holds the data you want to back up.
On the 'Export to Disk' tab, then select which databases you want to export.
If you want all the tables, select option ‘Export to self-contained file’, otherwise choose the other option for a selective restore
If you need advanced options, see other post, otherwise then click ‘Start Export’
In Window in new version you can export like this
The Data Export function in MySQL Workbench allows 2 of the 3 ways. There's a checkbox Skip Table Data (no-data) on the export page which allows to either dump with or without data. Just dumping the data without meta data is not supported.
In Workbench 6.3 it is supereasy:
On the "HOME"-view select one of the MySQL Connections: (localhost)
In the "Localhost" view click on "Server"--> "Data export"
In the "Data Export" view select the table(s) and whether you want to export only their structure, or structure and data,...
Click "Start Export"
In workbench 6.0
Connect to any of the database.
You will see two tabs.
1.Management
2. Schemas
By default Schemas tab is selected.
Select Management tab
then select Data Export .
You will get list of all databases.
select the desired database and and the file name and ther options you wish and start export.
You are done with backup.
I am using MySQL Workbench 8.0:
In Workbench 6.3 go to Server menu and then Choose Data Export. The dialog that comes up allows you to do all three things you want.

How do I rename a MySQL database (change schema name)?
(46 answers)
Closed 10 days ago.
How can I rename the MySQL database name using query?
I tried rename database via phpmyadmin and getting the following error,
SQL query:
RENAME DATABASE test TO test_bkp
MySQL said:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DATABASE test To test_bkp' at line 1
In phpmyadmin you can just click on your database, then go to the Operations tab which lets you rename it.
It says here that:
This statement was added in MySQL 5.1.7 but was found to be dangerous
and was removed in MySQL 5.1.23. It was intended to enable upgrading
pre-5.1 databases to use the encoding implemented in 5.1 for mapping
database names to database directory names (see Section 9.2.3,
“Mapping of Identifiers to File Names”). However, use of this
statement could result in loss of database contents, which is why it
was removed. Do not use RENAME DATABASE in earlier versions in which
it is present.
You can import all data into a new database then delete the old one.
It is also possible to use the RENAME TABLE statement using same from/to table name but different from/to database. There are a few catches.
CREATE DATABASE `test_bkp`;
RENAME TABLE
`test`.`table1` TO `test_bkp`.`table1`,
`test`.`table2` TO `test_bkp`.`table2`,
`test`.`table3` TO `test_bkp`.`table3`;
It's been disabled by the developers. See http://dev.mysql.com/doc/refman/5.1/en/rename-database.html
Adding to this, I'd use a copy (then delete) rather than a rename. Have a look at Cloning a MySQL database on the same MySql instance
You can do this in MySQL < 5.1.23
with
RENAME {DATABASE | SCHEMA} db_name TO new_db_name;
In later versions have a look at
ALTER {DATABASE | SCHEMA} [db_name]
Ok, so if the rename option doesn't show, here a quick way of cloning a database using phpMyAdmin:
Open the database you want to copy
Click the Operations tab.
where it says "Copy database to:" type in the name of the new database.
Select "structure and data" to copy everything or "Structure only"
Check the box "CREATE DATABASE before copying" to create a new database.
Check the box "Add AUTO_INCREMENT value."
Click on the Go button to proceed.
NB before deleting the old database, make sure that passwords have also copied over.
in wamp server
click on databases
then choose your database
from header menu choose operations
make the new name
it will rename the database
but actually it create a new database copy all the data then drop the old data base
Export current database.
create a new database with a name you want.
import old database file on the new database.
Well, it's possible to rename your database but here's the logic behind the rename option.
1. Xampp creates a new database with the name
2. Xampp copies all table and data in it from the previous database
3. Xampp migrates data to the new database table and drops the previous database
Steps to rename Database
1. Click the Operations option in the nav pane
2. Find the ' Rename database to ' Spot, and input new name in the input field
3. Tick the ' Adjust privileges ' checkbox
4. Click go
I hope this works! :)
you can export your databse table, create a new one and import table to the new database!
also you can rename your data base using phpmyadmin by selecting your database and click on operations tab and rename your database!
the last and not recommended way is create a new databse and use this, but you may lost your data!
CREATE DATABASE new_db_name / DROP DATABASE old_db_name
I am trying to export the DataBase i have at MySQL Workbench but I am having troubles to generate the INSERT statements on the .sql file.
I order to export the data, I do the reverse engineering for the database i want to export. Then, i go to
File / Export/ Forward Engineer SQL CREATE Script
And once in there, i select the option Generate INSERT Statements for Tables.
The result only generates the code for the create tables.
Is there any way to create the insert statements for the data?
Thanks
For older versions:
Open MySQL Workbench > Home > Manage Import / Export (Right bottom) / Select Required DB > Advance Exports Options Tab >Complete Insert [Checked] > Start Export.
For 6.1 and beyond, thanks to ryandlf:
Click the management tab (beside schemas) and choose Data Export.
I had some problems to find this option in newer versions, so for Mysql Workbench 6.3, go to schemas and enter in your connection:
Go to Tools -> Data Export
Click on Advanced Options
Scroll down and uncheck extended-inserts
Then export the data you want and you will see the result file as this:
You can do it using mysqldump tool in command-line:
mysqldump your_database_name > script.sql
This creates a file with database create statements together with insert statements.
More info about options for mysql dump: https://dev.mysql.com/doc/refman/5.7/en/mysqldump-sql-format.html
If you want to export just single table, or subset of data from some table, you can do it directly from result window:
Click export button:
Change Save as type to "SQL Insert statements"
In MySQL Workbench 6.1.
I had to click on the Apply changes button in the insertion panel (only once, because twice and MWB crashes...).
You have to do it for each of your table.
Then export your schema :
Check Generate INSERT statements for table
It is okay !
Go to Menu Server and Click on Data Export. There you can select the table and select the option Dump Structure and Data' from the drop-down.
For the latest version of MySql Workbench
Click on the Server menu in the top menu bar
Select 'Data Export' submenu
It will open up the Object Selection window where you can select the appropriate database which has the desired tables
Once you select the database in the left side all the tables will appear in the right side with radio buttons
Select the radio buttons in front of needed tables
Just below the table selection you can see a dropdown to select Dump Structure Only or Data only or Structure & Data
Under Objects to Export tick the box if you need stored procedures or events also. If you don't need those then untick those
Under export option change the exporting file name and path
If you want to create the schema once you import the dump file then tick include create schema
Press Start Export button in the right-hand side corner. once it successful the summary will be showing in the Export progress tab
