When trying to write to a Snowflake database using a DSN-less connection string in the Output Data tool and when a Boolean column exists in the data set, the following error occurs:
SQL compilation error: Unsupported data type 'bit'.
If the Boolean column was removed with a Select tool in the workflow, data will write successfully.
Output Data tool
DSN-less connection string set up
Boolean data type
Snowflake ODBC Drivers
Lua scripts are not being used when using a DSN-less connection string in the workflow, either directly in the Input/Output tool or within a saved Gallery data connection. Lua scripts map driver and database data types to Alteryx types. Since the Lua script is not being used with a DSN-less connection string, the bit data type is being used by default, which will not work with Snowflake.
Create a System DSN connection to Snowflake for either the Output Data tool or a Gallery Data connection set up.
If using a Gallery set up, ensure that both DSN connection setups are configured and named identical on the Alteryx Server and client Designer machine.
