How to import an Excel file into the Oracle table

This topic describes how to import data from a MS Excel 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 Import 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 wizard tab.
2. On the Data Import > Source file tab, select the Excel (for Excel 97-2003) or Excel 2007 import format, specify a location of the 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 selected a table in Database Explorer before opening the Data Import wizard, 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, use additional options to customize data import, and then click Next:

   • If the source data is located on several sheets, specify which of them to choose for the import.
   • Set the data range to import. You can see it highlighted with green in the Preview section. If you want to import the data partially, clear the Detect a range automatically check box and enter the Start Cell and End Cell values or click the next to these fields and double-click a cell on the Preview grid. The specified range will be highlighted with green, skipped lines will be highlighted with white.
   • Select to import the data either in rows or in columns.
   • Specify the header position if required. It will be highlighted with blue in the Preview section. If you don’t specify the header position, the imported columns will get default names - column1, column2, etc.

   

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. If you are importing the data into a new table, dbForge Studio for Oracle 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.)

   You can see the Target columns on the top and the Source columns at the bottom of the wizard page.

   Note

   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 that 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 the 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.
