Summary: this tutorial shows you how to copy a MySQL database on the same server and from a server to another.

Copy a MySQL database on the same server

To copy a MySQL database, you need to follow these steps:

  1. First, create a new database using CREATE DATABASE statement.
  2. Second, export all the database objects and data of the database from which you want to copy using mysqldump tool.
  3. Third, import the SQL dump file into the new database.

For the demonstration, we will copy the classicmodels database to classicmodels_backup database.

Step 1. Create the classmodels_backup database:

First, log in to MySQL database server:

Then, use CREATE DATABASE statement as follows:

Third, use SHOW DATABASES command to verify:

MySQL database server returns the following output:

As you see, we have created the classicmodels_backup database successfully.

Step 2. Dump database objects and data into SQL file using the mysqldump tool.

Suppose, you want to dump the database objects and data of the classicmodels database into an SQL file located at D:db folder, here is the command:

Basically, this command instructs mysqldump to log in to the MySQL server using the rootuser account with a password and exports the database objects and data of the classicmodels database to d:dbclassicmodels.sql. Note that the operator (>) means exporting.

Step 3. Import the d:dbclassicmodels.sql file into classicmodels_backup database.

Note that the operator ( <) means importing.

To verify the import, you can perform a quick check by using the SHOW TABLES command.

It returned the following output:

As you see, we have successfully copied all the objects and data from the classicmodels database to classicmodels_backup database.

Copy a MySQL database from a server to another

To copy a MySQL database from a server to another, you use the following steps:

  1. Export the database on the source server to a SQL dump file.
  2. Copy the SQL dump file to the destination server
  3. Import the SQL dump file to the destination server

Let’s take a look at how to copy the classicmodels database from a server to another.

First, export the classicmodels database to db.sql file.

Note that --database option allows mysqldump to include both CREATE DATABASE and USE statements in the SQL dump file. These statements will create the classicmodels database in the destination server and make the new database as the default database for loading the data.

In short, the following statements are included at the beginning of the SQL dump file when we use --database option.

Third, import the db.sql file to the database server with the assumption that the db.sql file was copied to c:tmp folder.

In this tutorial, you have learned step by step how to copy a MySQL database on the same server and copy database from a server to another.

You can use a variety of methods to export data and object structures from your databases. These methods include usage of various generators, data extractors, and shortcuts. Also, you can export data in TXT, CSV, JSON, XML, Markdown, Excel, and other formats. You can select a predefined extractor or create your own.

In DataGrip, you export object structures and data separately. It means that you can export a structure of a table and then export data from the table. The full data dump is available for PostgreSQL and MySQL with the help of mysqldump and pg_dump. The full data dump includes structures of all database objects and data of these objects in a single file. For more information, see Create a full data dump for MySQL and PostgreSQL.

Exporting object structures

Data definition language (DDL) defines the structure of a database, including rows, columns, tables, indexes, and other elements. In DataGrip, you can generate data definition structures by using shortcuts with predefined settings or by using the SQL Generator and customize the export settings.

Ubuntu Dbeaver Mysqldump

Generate DDL definitions for database objects

  • In the Database tool window (View Tool Windows Database ), right-click a database object and select SQL Scripts SQL GeneratorCtrl+Alt+G.

    On the right toolbar, you can find the following controls:

    • : copy output to the clipboard.

    • : save output to a file.

    • : open output in a query console.

The DEFINER clause specifies the security context (access privileges) for the routine execution. In MySQL and MariaDB, select Skip `definer = ...` clause to skip this clause when you generate DDL for a procedure or a function.

Change output settings of the SQL Generator

  1. In the Database tool window (View Tool Windows Database ), right-click a database object (for example, a table) and select SQL Scripts SQL GeneratorCtrl+Alt+G.

  2. In the SQL Generator tool window, click the File Output Options icon ( ).

  3. From the Layout list, select a method that you want to use:

    • File per object: generates a set of SQL files.

    • File per object with order: generates a numbered set of SQL files.

Generate a DDL definition to the query console

  • In the Database tool window (View Tool Windows Database ), right-click a database object and select SQL Scripts Generate DDL to Query Console.

Generate a DDL definition to the clipboard

  • In the Database tool window (View Tool Windows Database ), right-click a database object and select SQL Scripts Generate DDL to Clipboard.

    If your database stores DDL of the object, you can retrieve DDL from the database by selecting the Request and Copy Original DDL.

Export data

You can export database data as SQL INSERT and UPDATE statements, TSV and CSV, Excel, Markdown, HTML tables and JSON format. When you export to a file, a separate file is created for each individual table or view.

To configure CSV extractors, see Configure an extractor for delimiter-separated values. In CSV settings, you can set separators for rows and headers, define text for NULL values, specify quotation, create new extractors for formats with delimiter-separated values.

To export data in binary formats (for example, XLSX), use the Export Data dialog.

Dbeaver

Before DataGrip 2020.1, if you select the default extractor from the list, you set this extractor as default for the whole IDE. Beginning from DataGrip 2020.1, you set the extractor for a single table. If you open a different table, the extractor defaults to CSV.

Export data from the Database tool window

  1. In the Database tool window (View Tool Windows Database ), right-click a database object and navigate to Export Data to File(s).

  2. In the Export Data dialog, customize the following settings:

    • Extractor: select the export format (for example, Excel (xlsx) ).

    • Transpose: select to export data in the transposed view. In this view, the rows and columns are interchanged.

    • Add table definition (DDL): add a table generation code (CREATE TABLE or ALTER TABLE ).

    • Computed: include virtual columns that are not physically stored in the table (for example, the IDENTITY column).

    • Generated: include auto-increment fields for INSERT and UPDATE statements .

    • File name: type a filename. This option is available only if you export one table.

    • Output directory: select a storage path.

  3. To copy the generated script to the clipboard, click Copy to Clipboard. To save the script to a file, click Export Data to File.

Mysqldump

Export data from the data editor

  • To export data to a file, open a table or a result set, click the Export Data icon ( ). Configure the export settings and click Export to File.

  • To export the whole result or the whole table to the clipboard, open a table or a result set, right-click the result or the table and select Export Table to Clipboard.

    In contrast to the Export to Clipboard action, the Copy action Ctrl+C only copies the selection or all the rows on the current page. To copy rows on the current page, double-click the table and press Ctrl+C. Alternatively, click a cell, press Ctrl+A and then Ctrl+C. To configure a number of rows on a page, see Set a number of rows in the result set.

Export data from a MongoDB collection

  1. Right-click the collection that you want to export and select Export Data to File.

  2. In the Export Data dialog, click the Extractor drop-down list and select JSON.

    The output of this operation is MongoDB Extended JSON. Read about MongoDB Extended JSON in MongoDB Extended JSON (v2) at docs.mongodb.com.

Create a full data dump for MySQL and PostgreSQL

You can create backups for database objects (for example a schema, a table, or a view) by running mysqldump for MySQL or pg_dump for PostgreSQL. mysqldump and pg_dump are native MySQL and PostgreSQL tools. They are not integrated into DataGrip. You can read about them at dev.mysql.com and postgresql.org.

Dbeaver Mysqldump Path

Export data with mysqldump or pg_dump

  1. In the Database tool window (View Tool Windows Database ), right-click a database object and navigate to:

    • Export with 'mysqldump': for MySQL data sources.

    • Export with 'pg_dump': for PostgreSQL data sources.

  2. In the Export with <dump_tool> dialog, specify the path to the dump tool executable in the Path to <dump_tool> field.

    (Optional) Edit the command-line options in the lower part of the dialog.

  3. Click Run.

Productivity tips

Copy a table to another schema

  1. Right-click a table and select Copy Table to. Alternatively, press F5.

  2. Enter a schema name and click OK.

  3. (Optional) In the Import dialog, modify table settings.
