How to import data from ODBC to SQL Server

ODBC (Open Database Connectivity) is a standard API for accessing database management systems. ODBC is not limited to a single DBMS owing to an ODBC driver, which is used as a translation layer between the application and the DBMS. The application uses ODBC functions through an ODBC driver manager with which it is linked, and the driver passes the query to the DBMS.

To import data from ODBC:

1. In Object Explorer, right-click a database, point to Data Pump, and then click Import Data.

2. On the Source file page, select the ODBC import format. Load import options from a template file in User Templates if you saved it previously. Specify the path and the name of your source file and click Next.

3. On the ODBC options page, you can configure the data source specification (either using a connection string or by specifying a system or user data source name). Then enter your login information and click Next.

To configure ODBC drivers for a specific server, see the following topics:

ODBC options

4. On the Destination page, select a server connection, a database and its schema. Then select whether the data will be imported into a New table (in this case, you need to specify its name) or into an Existing table. Click Next.

Destination tab

5. On the Data formats page, you have two auxiliary tabs. The first one is Common Formats, where you can specify the formats for null strings, thousand and decimal separators, boolean variables, date and time. There is also a check box Autodetect Date and Time format, selected by default.

The second one is Column Settings, where you can configure the format settings for separate columns. You have 4 options here: Null String, Left Quote, Right Quote, and Date and Time. Note that if a format mask is not set, the application will identify date/time values automatically.

6. On the Mapping page, you can map the source columns to the target ones. If you are importing data into a new table, the application will automatically create and map all the columns. You can see the results in the Preview section.

Mapping tab

Note

If you are importing into an existing table, only columns with the same names will be mapped, and 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.

Note

You should select at least one column with a primary key by selecting the corresponding Key check box. Otherwise some of the import modes on the Modes page will be disabled.

You can click View on the toolbar to view column properties.

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

7. On the Modes page, select an import mode. There are 5 available modes:

Modes tab

  • Append - add records to the target table
  • Update - update a record in the target table with a matching record from the source
  • Append/Update - update a record if it exists in the target table; otherwise, add a record
  • Delete - delete records in the target table that match records in the source
  • Repopulate - delete all records in the target table and repopulate them from the source

Optionally, you can select the check boxes Use a single transaction and Use bulk insert (the latter of which reduces the quantity of statements and speeds up import, but can affect the error handling mechanism).

8. On the Output page, you have 3 options:

Output tab

  • Open the data import script in the internal editor.
  • Save the data import script to a file. To use this option, specify the path and the file name. Additionally, you can select the check boxes to Add timestamp to the file name and Open in the internal editor.
  • Import data directly to the database.

9. On the Errors handling page, you can specify the error processing behavior (using one of the three available options: Prompt the user for an action, Ignore all errors, or Abort at the first error) and opt to write reports to a log file with a specified path.

Errors handling tab

Note

If you want to save your import settings as templates for recurring scenarios, click Save Template.

10. Click Import. When your data import is successfully completed, you can view the log file or click Finish to exit the wizard.

Finish
