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 type natively in Snowflake target tables. From 6.1.5/7 through 6.3.5/3, HVR only supports the JSON format for VARIANT columns. Since 6.3.5/4, HVR also supports the XML format. However, XML is not supported when using Snowflake internal staging.
HVR Compare does not support the VARIANT type. Using Compare with VARIANT columns may produce unreliable results.
A known issue occurs when using the VARIANT data type with HVR Agent versions earlier than 6.1.5/7 together with HVR Hub versions 6.1.5/7 or later, but earlier than 6.2.0/24 or 6.2.5/10. In this scenario, the following error may appear: F_JD20EC: An unknown datatype with code 'vt.4.16777216'. To resolve this issue, upgrade either the HVR Agent to version 6.1.5/7 or later, or the HVR Hub to version 6.2.0/24, 6.2.5/10, or later.
