JSON Import

This topic describes how to import data from a JSON file.

Note

Data Import Wizard pages can slightly differ due to the product you have been using.

1. Decide what table to import the data to:

   For a new table:

   • On the Database menu, click mport Data. The Data Import wizard opens.

   For an existing table:

   • In Database Explorer, right-click a table and select Import Data on the shortcut menu. The Data Import wizard opens with predefined parameters: an Oracle connection, a database, and a table to import the data to.

     -or-

   • On the Database menu click Import Data, and select a required table on the Destination table wizard page.

2. On the Data Import > Source file tab, select the JSON import format, specify a location of Source data, and click Next.

3. On the Data Import > Destination tab, specify an Oracle connection, a database, and a table to import the data to, and then click Next.

   Note

   If you imported data to the existing table, the wizard will open with the predefined connection parameters of the selected table.

   To create or edit Oracle connections, use the corresponding options.

4. On the Data Import > Options tab, preview the Source data and specify the Source encoding:

   

5. On the Data Import > Data formats tab, adjust data formats for the Source data and click Next.

6. On the Data Import > Mapping tab, map the Source columns to the Target ones.

   Note

   If you are importing the data into a new table, dbForge Studio will automatically create and map all the columns. If you are importing into an existing table, only columns with the same names will be mapped, the rest should be mapped manually. (If no columns with the same name are found, they are mapped in succession - the 1st column in Source with the 1st column in Target, etc.)

   To cancel mapping of all the columns, click Clear Mappings on the toolbar. To restore it, click Fill Mapping.

   If you are importing to a new table, you can edit the Target column properties by double-clicking them on the top grid. Select the Key check box for a column with a primary key and click Next. Note you should select at least one column with a primary key, otherwise some of import modes on the Modes wizard page will be disabled.

7. On the Data Import > Modes tab, select an import mode to define how dbForge Studio should import the data, and then click Next.

8. On the Data Import > Output tab, select output options to manage the data import script and click Next:

   • Open the data import script in the internal editor
   • Save the data import script to a file
   • Import data directly to the database
9. On the Data Import > Errors handling tab, select the way to handle errors during import, specify logging options, and click Import.
10. On the progress page, dbForge Studio will notify you whether the import completed successfully or failed. To view the log file, click Show log file.

11. To close the wizard, click Finish.

    Note

    You can save the import settings as a template for later use. To save the selected settings, click Save on any wizard tab. Next time you should only select a template and specify a location of the Source data - all the settings will be already set. For more information, see Saving and Using Templates.
