Data Type Mapping for Google BigQuery
This section lists the mapping of data types for Google BigQuery.
Google BigQuery as Target
When Google BigQuery is used as a target location, following is the mapping of HVR repository data types to the corresponding data type in Google BigQuery.
Text in green cell indicates the native data type of the DBMS
