Import data
In the Database tool window () , right-click a data source, or a schema and select .
In the file browser window that opens, navigate to the SQL file that you want to run.
Click Open.
You can view the output in Run tool window. For more information about tool window controls, refer to Run tool window.
Import data from CSV files
CLion uses data extractors to import data from CSV files. For more information about data extractors, refer to the Data extractors topic.
In the Database tool window () , right-click a schema or a table and select .
Navigate to the CSV files and select them.
In the mapping tree of Import dialog, select the mapping node (
) and specify the data conversion settings.You can select in which 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 Schema and Table fields.
In the mapping tree, select the source file to configure its settings. To mark the first row as a header, select First row is header.
Apply the changes and close the dialog.
Import data from tabular data files
CLion uses scripted data loaders to import data from tabular data files. For more information about scripted data loaders, refer to the Data loaders topic.
In the Database tool window () , right-click a schema or a table and select .
Navigate to the tabular data files and select them.
In the mapping tree of Import dialog, select the mapping node (
) and specify the data conversion settings.You can select in which 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 Schema and Table fields.
In the mapping tree, select the source file to configure its settings. To mark the first row as a header, select First row is header.
Apply the changes and close the dialog.
Import tables
Select the tables that you want to copy to a different schema, database, or existing table.
Open the Import dialog. To do that, you can use the following actions:

In the mapping tree, select the source file to configure its settings.
(Optional) Select Insert inconvertible values as null if you want to insert NULL when the IDE meets an inconvertible value.
Apply the changes and close the dialog.
Restore Microsoft SQL Server table data
You can restore a Microsoft SQL Server table data by using the bcp utility. The tool is not integrated into CLion. You can read about it at learn.microsoft.com.
In the Database tool window () , right-click the table that you want to import your data to and select .
In the Restore with bcp (<data_source_name>) dialog, specify the path to the bcp executable in the Path to bcp field.
In the Source file, specify the path to the file that you want to restore the data from.
Click Run.
Restore a full data dump for MySQL and PostgreSQL
You can restore data dumps by using 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 () , 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 database objects except for the data source level.
Restore with "psql": for PostgreSQL data sources. The psql option is available for the most 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.
(Optional) Edit the command-line options in the lower part of the dialog.
Click Run.
Import dialog
The Import dialog appears when you import a file, a table, or a query result set into your database.
In the mapping tree that is in the upper-left pane of this dialog, you can create file-to-table, table-to-table, and query-to-table mappings (). In the settings pane in the upper-right part of the dialog, configure mapping settings and change settings of the sources (CSV file, table, and query). The preview pane in the bottom part of the dialog displays generated previews of your data, of the source data with different source settings, and of DDL statements.
