I want to take the whole database. Where do I find the database file?
And is there a way to write the whole database with all data to a text file (like the one in SQL Server)?
How to generate SQL scripts for your database in Workbench
In Workbench Central (the default "Home" tab) connect to your MySQL instance, opening a SQL Editor tab.
Click on the SQL Editor tab and select your database from the SCHEMAS list in the Object Browser on the left.
From the menu select Database > Reverse Engineer and follow the prompts. The wizard will lead you through connecting to your instance, selecting your database, and choosing the types of objects you want to reverse engineer.
When you're all done, you will have at least one new tab called MySQL Model. You may also have a tab called EER Diagram which is cool but not relevant here.
Click in the MySQL Model tab
Select Database > Forward Engineer
Follow the prompts. Many options present themselves, including Generate INSERT Scripts for Tables which allows you to script out the data contained within your tables (perfect for lookup tables).
Soon you will see the generated script in front of you. At this point you can Copy to Clipboard or Save to Text File.
The wizard will take you further, but if you just want the script you can stop here.
A word of caution: the scripts are generated with CREATE commands. If you want ALTER you'll have to (as far as I can tell) manually change the CREATEs to ALTERs.
This is guaranteed to work, I just did it tonight.
Q#1: I would guess that it's somewhere on your MySQL server?
Q#2: Yes, this is possible. You have to establish a connection via Server Administration. There you can clone any table or the entire database.
This tutorial might be useful.
EDIT
Since the provided link is no longer active, here's a SO answer outlining the process of creating a DB backup in Workbench.
In MySQL Workbench 6, commands have been repositioned as the "Server Administration" tab is gone.
You now find the option "Data Export" under the "Management" section when you open a standard server connection.
there is data export option in MySQL workbech
I found this question by searching Google for "mysql workbench export database sql file". The answers here did not help me, but I eventually did find the answer, so I am posting it here for future generations to find:
Answer
In MySQLWorkbench 6.0, do the following:
Select the appropriate database under MySQL Connections
On the top-left hand side of screen, under the MANAGEMENT heading, select "Data Export".
Here is a screenshot for reference:
None of these worked for me. I'm using Mac OS 10.10.5 and Workbench 6.3. What worked for me is Database->Migration Wizard... Flow the steps very carefully
In the top menu of MySQL Workbench click on database and then on forward engineer. In the options menu with which you will be presented, make sure to have "generate insert statements for tables" set.
Try the export function of phpMyAdmin.
I think there is also a possibility to copy the database files from one server to another, but I do not have a server available at the moment so I can't test it.
Using Windows 10 and MySql 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 the button Start Export
Surprisingly the Data Export in the MySql Workbench is not just for data, in fact it is ideal for generating SQL scripts for the whole database (including views, stored procedures and functions) with just a few clicks. If you want just the scripts and no data simply select the "Skip table data" option. It can generate separate files or a self contained file. Here are more details about the feature: http://dev.mysql.com/doc/workbench/en/wb-mysql-connections-navigator-management-data-export.html
in mysql workbench server>>>>>>export Data
then follow instructions it will generate insert statements for all tables data each table will has .sql file for all its contained data

We have to make some changes to our databases (creating tables, Running special SQL queries).
Is there some way in MySQL Workbench to import a structure, edit it with a graphical interface and then getting some piece of SQL Code that I can use to transform my old structure into the new structure?
To explain my problem a bit further:
I need a way to transform my MySQL database structure to a new structure (adding databases and values into those tables) without interrupting the production environment for too long.
I would prefer a solution in MySQL Workbench (I'm using version 6.3)
but also accept any other answer to do this (for free)
Okay, I actually found a solution!!
What I was looking for is called an "SQL ALTER Script" or a Schema Sync.
Steps to generate a SQL Alter Script with MySQL Workbench:
Open MySQL Workbench
Click File -> New Model
Click Database -> Synchronize With Any Source
Click Next
Select a SQL Dump File as Source (this is the new structure)
Select a SQL Dump File as Destination (this is the old structure)
At Send Updates To select a Folder and Filename where the ALTER Script will be placed.
Click Next
Click Next
Make sure default_schema is checked and Click Next
Click Next
Preview your SQL Code and Click Next
You now successfully generated your SQL Alter Script and it got saved into the specified file.
But Note that you will have to open the SQL File in an editor and replace default_schema with your database name
I built a database schema (or Model?) with MySQL Workbench. I'd like to now make it into an actual database.
I've seen Forward and Reverse engineer options and can't find a clear answer on if either are what I need.
How can I turn this into an actual database?
This for mysql workbench version 6.0 and for exporting a schema.
Select tab MySQL Model
Select File->Export->Forward Engineer SQL Create
Place a file name to be exported in the Output SQL Script File, choose your options, next
Export MySQL table Objects,
filter tables
Then a file is created which you can import to your database and it creates schemas if not exists, creates tables if not exists.
In the case of models, you need to pay, many bucks, for a tool that creates schemas, tables, indexes, cascading, and all stuff associated to an existing data model.
In order to realize a modeled schema structure on a real server you would use either forward engineering or synchronization. The first is if you have just the model and want it to create all the objects in the target schema(s). Synchronization on the other hand is a means to synchronize your model and an existing schema (two-way). That is, objects not existing or changed in your model are created or adjusted on the server and vice versa. There's no need to create a separate SQL script and apply that manually.
For both action see the Database menue in MySQL Workbench when a model is open.
The official documentation has a relevant article. http://dev.mysql.com/doc/workbench/en/wb-getting-started-tutorial-creating-a-model.html
Jump to step 11.
As of MySQL Workbench 8.0, go to the menu item Database > Forward Engineer. After specifying your database connection and model export options, you’ll be able to create the database you have designed.
See MySQL Workbench Manual :: 9.4.1.2 Forward Engineering to a Live Server for details.
I have an .sql script that contains inserts and creates tables. I used the "Create EER Model From Script"
It created the tables but I can't see the data inside these tables.
I went to the query menu and tried to make a query but it gives me an error about not being able to connect to localhost.
Am I doing it right?
As documented under Create EER Model from SQL Script:
Clicking this action item launches the Reverse Engineer SQL Script wizard. This is a multi-stage wizard that enables you to select the script you want to create your model from.
For further information, see Section 7.7.9.1, “Reverse Engineering Using a Create Script”.
Following that link:
However, if you are working with a script that also contains DML statements you need not remove them; they will be ignored.
Instead, you want the Manage Data Import/Export option under Server Administration (within the Workspace section of the Home window).
You are confusing things here. Creating a model from a script is a process where meta data is examined and a model is created that you can then use to modify your schema structure, further design your db objects and all that. Modeling is a design process for the structure of your schema/db so it only deals with meta data. It's also used for documentation (e.g. in teams).
On the other hand there's normal sql work with existing db objects and/or actually creating/deleting/modifying db objects. In order to do the latter you must have an understanding of the design of the schema (which you could get by using the modeling part of MySQL Workbench, but not only by that). This is also the place to load a script, run it to insert data and such.
The error you mentioned regarding the connection is yet another problem and you need to solve this first to be able to even access your server. And yes, you have to install a server first somewhere. MySQL Workbench is a tool to visually work with your server(s) in opposition to the MySQL command line client which is a pure text interface (but still also a client application for your MySQL servers).
If you are on Windows and want a MySQL server installed locally (e.g. for testing) your best option is to download the MySQL Installer which greatly simplifies installing any of the tools from the MySQL family (server, client tools, connectors, documentation and more).
I have this requirement to migrate a live SQL server 2008 to MySQL server 5, I have tried the MySQL migration toolkit but its throwing lots of migration errors. Someone here in Stackoverflow suggested that I use Talend. I installed Talend Open Studio for Data Integration but its quite a general purpose tool that there's no quickstart to do database migration like what I really needed.
Where can I find a quickstart guide to use Talend for such job?
Talend is quite generic data integration tool, but you should get the job done by following these steps (which actually apply to any database-types: PostgreSQL, Oracle, etc.):
Create a new database connection in Repository-panel, to the Metadata-"Db Connections"-node. Name it and select "DB Type" as "Microsoft SQL Server" (or whatever is your source database) and give the connection details.
Create another new database connection, but this time as "MySQL" (or whatever is your target database).
Create a new job to "Job designs" (in Repository).
Expand the "SQL Server"-DB-connection from the Metadata, and drag the desired table (under "Table schemas") to the work-area of the job AND select tMSSqlInput.
Drag the MySQL-DB-connection from the Metadata to the work-area AND select tMysqlOutput. Define the target table.
Click Palette and drag tMap component to the work-area between the two previous components.
Connect tMSSqlInput to tMap and tMap to tMysqlOutput with arrows. You do that by right-clicking the tMSSqlInput, selecting Row-Main and dragging the arrow to the tMap. Same from tMap to tMysqlOutput.
Double-click the tMap, select all columns from the left and drag them to the right. The tMap component allows you to make data transformations. It might be that you wouldn't even need to use the tMap between the database-components. But it is good to have just in case.
Run the job, and troubleshoot as necessary. If something goes wonky, restart Talend Studio or just close and open the job, in many occasions it helps.
The MySQL Migration Toolkit is deprecated long time ago. You should try the new Migration Wizard that comes with MySQl Workbench 5.2.41. It will help you to migrate both the tables and their data. You can have an overview of its capabilities here:
How-To: Guide to Database Migration from Microsoft SQL Server using MySQL Workbench
If you need to get started with Talend, I can suggest you check our documentation page http://www.talend.com/resources/documentation.php , where you will be able to find installation guides and user manuals.
Also, there's an interesting section on our website where you will be able to check out our tutorials, that should help out: http://www.talendforge.org/tutorials/menu.php
xybrek, unfortunately there's no tutorial that covers your specific case exactly.
Download the manuals that Bart linked to and start trying things out in Talend.
The components you'll be looking at are:
tMssqlInput - reads a table in a MsSQL db
tMySQLOutput - directs a flow of data, say the output of the mssqlinput component, into a mysql table
tMySQLRow - lets you execute a query on a mysql table/database
And possibly others. These are just some pointers to the more obvious components.
You can read more about those and see examples in the Reference Guide manual which covers all components in Talend.
Good luck!
In the freeware version of Toad for MySQL (latest version), I can generate a script of all tables in my database in one file. However, for stored procedures and functions, Toad generates a separate script/file for each one.
Ideally, I'd like a simple step to generate a script for all objects in my database (tables, views, procedures, functions, triggers) to a single file.
Is that possible in Toad for MySQL?
I am happy to report that HeidiSQL does exactly what I need it to do. This feature alone is worth having the 3 MB .exe on your system:
As a bonus, it's lightweight and fast. It can't do everything Toad for MySQL does, but for most tasks, I will default to Heidi instead of SUPER SLOW Toad!
If someone can still answer my question about how to do this operation in Toad for MySQL, I will change my accepted answer.
(and another option I have is using mysqldump)
I think I have found a definitive answer. This operation cannot be done in Toad for MySQL. What do all of you do?!
SQL Export suggestions on Toad for MySQL forums
We have been asking for this feature for many years and it has been never implemented. We hope to have that this year. We'll see.
-Ernest
I don't know why so few people are asking for those "Scripts" enhancement features. I comes from the Microsoft SQL sides, with Toad, I can't select any objects(views, procedures ) then generate DDL and rerun it in Production system. The stored procedures script generated from Toad can't even run in Production unless "Delimiter" is added.
-Lawrence
Note: I have found a suitable option for now using HeidiSQL (see other answer), but HeidiSQL is not as robust as Toad for MySQL, and I would prefer not to mix IDEs.
For anyone still needing an answer for Toad...
Go to the Object Explorer -> select all the tables -> Right click and select 'Send To -> Editor As Script'
What about Database -> Export -> Generate schema script. After that - spefify DDL file name and on Object types tab select needed types.
PS: oops, I've given a recipe for Toad for Oracle, but may be for mysql it is similar
Go to tools -> Export --> Export wizard
Click Next -> Add -> Databases
Select the databases you want to export
Click Next
Select the output format as SQL script
Click Next -> Next -> Next -> export data
Your .sql scripts will exported to the file location
Found a workaround how to do it.
In Object Explorer select all tables then Generate SQL > Creation Script. You have to run it few times on fresh database if you have relations.
Unfortunately this can not be done for procedures.
It can be achieved using Tools > Compare function.
You compare database with empty one, than after Toad compared databases Press Synchronize, then you will see option to open script in an editor.
