ETL+ for BigQuery Google Cloud

Installation Checklist

ETL+ Connection to ODBC

  • Click here to download and access Google BigQuery ODBC driver & documentation.

  • ODBC driver to use in ETL+:

    • Have your source system’s ODBC driver on the same Windows computer where ETL+ is

    • Create or use an ODBC System DSN (instead of User DSN)

    • The ODBC driver must have the same 32/64bit build as ETL+

    • Click here for Microsoft ODBC documentation.

  • If you haven’t installed ETL+ yet: ETL+ Deployment Instructions.

  • Login to ETL+ (help here).

  • Adding a new ODBC source: On ETL page’s left panel, click Add Source -> ODBC.

  • Maintaining an ODBC source: On ETL page’s left panel, right-click the ODBC source → Properties.

  • On the ODBC Data Sources page, select the correct ODBC Name from the list.

    • Can’t find your ODBC? Be sure ETL+ and the ODBC have the same 32/64bit build.

    • ODBC requiring credentials: double-click the ODBC nameenter credentialsConnect.

    • You might leave the Alias as is, or customize it.

    • Click Connect.

  • You’ll get back to the ETL page and see tables under the new ODBC source on the left panel.

Mapping and Loading Tables

  • To view tables available from your ODBC source on the left panel, right-click the ODBC source → Refresh.

  • To map an ODBC table to the data warehouse, double-click its name on the left panel, or right-click on it → Add Table.

    • You’ll now see the table added/mapped to the center panel.

  • To preview its data, right-click the table on the center panel → Preview.

  • To load its data to the data warehouse, right-click the table on the center panel → Load Now.

  • Click the Log icon (top right) to view data load results. Log page help here.

Schedule the Data Load

  • On the ETL main page, click Refresh Batch (top right icon on the center panel).

  • Select a Refresh Batch or create a new one to load your ODBC source data on a schedule (help here) → on the right panel, be sure the ODBC source tables to load have their boxes checked and in the desired load order.

  • To load them now, click the Refresh Batch Now (play icon) on the left panel for the desired Refresh Batch.

  • To schedule the data load:

    • Click WTS Settings -> enter the WTS parameters → Apply.

    • This step might require you to run ETL+ app as “Run as administrator” in Windows.

  • Click Close -> Close.


After ETL+ has loaded your ODBC source tables, this is to check if the data extraction process finished successfully and row count per extracted table matches with your ODBC source tables.


  • Login to ETL+ (help here).

  • On the ETL main page, click the top-right Log icon. Log page help here.

  • Scroll down on the log page and double-check that no table load failed, and the row count matches with the source ODBC tables. Following is an example highlighting two tables from a sample ODBC database and their loaded row count.

ODBC Syntax Tips

Invalid dates in SQL (click here): try the following CASE statements to work around them:

CASE WHEN Date1 BETWEEN '1800-01-01' AND '2500-01-01' THEN Date1 ELSE NULL END as Date1
CASE WHEN Date1 >= '1800-01-01' AND Date1 <= '2500-01-01' THEN Date1 ELSE NULL END as Date1
CASE WHEN Date1 >= {d'1800-01-01'} AND Date1 <= {d'2500-01-01'} THEN Date1 ELSE NULL END as Date1
