Connections
Using Connections, you can perform live queries on external databases.
If your company stores source data externally in data warehouses, you can use ThoughtSpot Connections to directly query that data and use ThoughtSpot’s analysis and visualization features, without moving the data into ThoughtSpot.
You can establish direct connections to the following external databases:

How it works
You create a connection to the external database, choosing the columns from each table that you want to explore in your live query. Primary key and foreign key relationships are imported along with the primary and foreign key tables. If there are any joins in the tables of your connection, they are also imported. After your connection is complete, it becomes a linked data source in ThoughtSpot that allows you to query the external database directly. It’s easy to apply transformations and filter the data also.
Key benefits
-
Set up and deploy ThoughtSpot faster by connecting directly to the external database.
-
Eliminate the need to move data into ThoughtSpot for analysis.
-
Centralize data management and governance in the external database.
-
Save significant time and money by avoiding ETL pipelines.
-
Connect to multiple external databases.
Limitations
| ThoughtSpot does not support joins across connections. |

Additional specific exceptions
The following list captures the specific limitations across the different databases supported through Connections. Databases not listed here have full support.
- General for all databases
-
- Sample values
-
ThoughtSpot does not internationalize sample values in tables.
- Google BigQuery
-
- Join support
-
Google BigQuery does not support PK-FK joins. Therefore, when using Connections, you must create joins explicitly in ThoughtSpot.
- Partitioned tables
-
When running a query on a partitioned table with the Require partition filter option enabled, you must specify the
WHEREclause. Without aWHEREclause specified, queries generate an error. To ensure that the query on such tables honors the partition condition, you must create a worksheet filter in ThoughtSpot.
- Azure Synapse
-
Azure Synapse supports up to 10
IF THEN ELSEstatements in a single query.Azure Synapse does not support foreign keys, so no PK-FK joins can be defined in Synapse.
- Teradata
-
Teradata does not support the function
AGGREGATE_DISTINCT.Teradata does not support the following data types:
JSON, INTERVAL, VARBYTE, BLOB, CLOB, PERIOD, XML, GEOSPATIAL. - SAP HANA
-
SAP HANA does not support the following functions:
PERCENTILE, AGGREGATE_DISTINCT, SPELLS_LIKE, EDIT_DISTANCE.SAP HANA does not support the following data types:
BLOB, CLOB, NCLOB, TEXT, POINT.SAP HANA does not support calculation views with mandatory input parameters. If you need to use calculation views in ThoughtSpot, you must remove the mandatory parameter requirement.
