Data Type Mapping for Snowflake
This section lists the mapping of data types for Snowflake.
Snowflake as Target
When Snowflake is used as a target location, the following is the mapping of Fivetran HVR repository data types to the corresponding data type in Snowflake.
Since 6.1.5/7, HVR supports the VARIANT data type in Snowflake target tables. It is supported as a native data type, and it only accepts JSON data. However, HVR Compare does not support the VARIANT data type. Using Compare with the VARIANT data type will produce unreliable results.
Text in green cell indicates the native data type of the DBMS
