Import

To import data from a script file, run the file as it is described in the Run SQL files page. In addition to script files, you can import data from a CSV, TSV, or any other text files that contain delimiter-separated values.

Import data to a database

In the Database tool window ( View | Tool Windows | Database) , right-click a data source, or a schema and select SQL Scripts | Run SQL Script….
In the file browser window that opens, navigate to the SQL file that you want to run and click Open.
Select the settings for your run configuration.
- Target data source / schema: databases or schemas against which you want to run your database scripts. This setting is dialect-dependent.
  If you select a data source as a target, RubyMine displays a schema in which the script will be run. It is the default schema.
- Script files: SQL files that you want to run. To add files, click the Add button () and navigate to files that you want to run. If a script contains schema switching, you will see a warning ().
Click Run.

Import delimiter-separated values into a database

In the Database tool window ( View | Tool Windows | Database) , right-click a schema or a table and select Import/Export | Import Data from File(s).
Navigate to the file that contains delimiter-separated values and double-click it.
In the Import "file_name" File dialog, specify the data conversion settings and click Import.
You can select in what schema to create a table and whether to import data to a new table or an existing one. To select a schema or a table, use Table and Target schema lists.
To mark the first row as a header, right-click the row in the Data Preview pane and select First Row Is Header.

Import multiple CSV files into a database

In the Database tool window ( View | Tool Windows | Database) , right-click a schema or a table and select Import/Export | Import Data from File(s).
Navigate to the files that contain delimiter-separated values, select them, and click Open.
In the Import "file_name" File dialog, specify the data conversion settings for every file. You can go through the files in the Sources pane. Click Import to import the files.
You can select in what schema to create a table and whether to import data to a new table or an existing one. To select a schema or a table, use Table and Target schema for all sources lists.
To mark the first row as a header, right-click the row in the Data Preview pane and select First Row Is Header.

Import multiple tables to a different schema, database, or existing table

Select tables that you want to copy to a different schema, database, or existing table.
Open the Import 'table_name' Table dialog. To open the Import 'table_name' Table dialog, you can use the following actions:
- Right-click the selection and navigate to Import/Export | Copy Tables to....
- Drag the selection to a schema or a database.
- Press Control+Shift+A, type copy tables to and press Enter.
From the Target schema for all sources list, select a schema in which you want to create a table. In case of a single table, this menu item is called Target schema.
In the Table list, type a name of a new table or select an existing table to add data to the selected table.
In the Sources list, click tables that you want to configure.
(Optional) Click the Add icon () to add columns, keys, and indexes.
(Optional) Select Insert inconvertible values as null if you want to insert NULL when the IDE meets an inconvertible value.
Select Disable indexes and triggers, lock table (may be faster) if you want to disable indexes and triggers during the import. Note that if you selected this option, it might lead to a situation when a trigger does not fire and fails to pass its results. Though it might improve the performance of the importing process. The option is available only when the target table (to which you copy values) has indexes or triggers.
Click Import.

Restore a full data dump for MySQL and PostgreSQL

You can restore data dumps by means of the mysql client utility for MySQL, or pg_restore or psql for PostgreSQL. The pg_restore option is used for custom-format pg_dump -Fc or directory-format pg_dump -Fd dumps. The psql option is used for SQL-format dumps.

If you see no restore options in the context menu, verify that you use a correct JDBC URL for the data source.

In the Database tool window ( View | Tool Windows | Database) , right-click a schema or a database and navigate to the Import/Export group:
- Restore with "mysql": for MySQL data sources. In the Path to mysql field, specify the path to the MySQL executable (for example, C:\Soft\mysql-8.0.19-winx64\bin\mysql.exe).
- Restore with "pg_restore": for PostgreSQL data sources. The pg_restore option is available for the most of database objects except for the data source level.
- Restore with "psql": for PostgreSQL data sources. The psql option is available for the most of database objects except for table and schema levels.
- Restore: for PostgreSQL data sources. Includes two tabs: pg_restore and psql.
In the Restore with <dump_tool> dialog, specify the path to the restore tool executable in the Path to <dump_tool> field.
Specify the full explicit path to the dump tool executable.
(Optional) Edit the command-line options in the lower part of the dialog.
Click Run.

Import dialogs

The Import "file_name" File dialog appears when you import CSV, TSV, or any other text files that contain delimiter-separated values.

Import delimiter-separated values into a database

Settings for files with delimiter-separated values

These setting are available in the Import File dialog only.

Item	Description
Formats	Select a template that successfully converts the file data into a table. You can change settings of predefined templates or add a new template. To add a template, click Add Format button (). To save changes, click the Save icon and select one of the following options: Save Changes: save changed settings of the current template are saved.

Quotation	Each line in the area under Quotation is a quotation pattern. A quotation pattern includes: Left: a quotation character that is inserted before a value. Right: a quotation character that is inserted after a value. Escape: an escape method or character for the cases when the quotation character is part of a value.

First column is header	Treat the first column as a column that contains row names.

The Import 'table_name' Table dialog appears when you import a table into an existing one, or to another database or schema.
