ODBC Simba driver for BigQuery

[hexeh]

Hello!

After updating Simbda Driver to latest version (2.2.0.1005) DSN-connections to BigQuery cause error:

ODBC: 
ERROR [HY000] 
[Simba][BigQuery] (100) Error interacting with REST API: Already Exists: Dataset PROJECT_ID:_bqodbc_temp_tables

I figured out Simba tried to create dataset for large results (it's name configured via LargeResultDataSetId option and is _bqodbc_temp_tables by default).

The problem seem to be caused by the fact I need multiple near-simalteneous updates for different tables and datasets - driver tried to create new temporary dataset for each new connection without explicit check of its existance and failes with already exists error. I've tried to unset this parameter value via DSN settings, but in that case default name is used when Standard SQL dialect is picked.

Obviously this behavior relates only to the Simba driver and can't be resolved outside of their team, but my question is - why is there no possibility to override advanced DSN settings inside ODBC connection string?

I've tried to define specific value via connection string as follows, but it is ignored for some reason:

= Odbc.DataSource(
	"dsn=" 
		& dsn_name 
		& ";LargeResultDataSetId=_tmp_results_" & report_suffix, 
	[
		HierarchicalNavigation=true, 
		CreateNavigationProperties = false
	]
)

Is there any option of guaranteed override inside Power BI?
