Does anyone here connect to BQ using JDBC successfully? I've been trying to make this work, as I did with ODBC, but with no luck.

I have JRE installed:

Code:
$ java -version
java version "10" 2018-03-20
Java(TM) SE Runtime Environment 18.3 (build 10+46)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+46, mixed mode)
I have the Magnitude Simba JDBC release 1.2.16.1020, which is JDBC 4.2-compatible from here.

I unzipped that into ~/ado/simba_jdbc, which is on my ado-path:

Code:
. adopath
  [1]  (BASE)      "/Applications/Stata/ado/base/"
  [2]  (SITE)      "/Applications/Stata/ado/site/"
  [3]              "."
  [4]  (PERSONAL)  "/Users/dimitriy/ado/"
  [5]  (PLUS)      "/Users/dimitriy/Library/Application Support/Stata/ado/plus/"
  [6]  (OLDPLACE)  "~/ado/"
  [7]              "~/ado/simba_jdbc"

I am able to jdbc connect (or there are no errors):

Code:
. #delimit cr
delimiter now cr
. set debug on

. local jar "GoogleBigQueryJDBC42.jar"

. local driverclass "com.simba.googlebigquery.jdbc.Driver"

. local url "jdbc:bigquery://https://www.googleapis.com/bigquery/v2:443;ProjectId=XXXX;OAuthType=YYY;OAuthRefreshToken=ZZZ;"

. local user "AAAA"

. local pass "BBBB"

. jdbc connect,  jar(`"`jar'"') driverclass("`driverclass'") url("`url'") user("`user'") password("`pass'")
Classpaths:
    file:/Applications/Stata/ado/base/jar/libstata-plugin.jar
Classpaths (add):
    file:/Users/dimitriy/ado/simba_jdbc/GoogleBigQueryJDBC42.jar
    file:/Applications/Stata/ado/base/jar/libstata-plugin.jar
Classpaths:
    file:/Applications/Stata/ado/base/jar/libstata-plugin.jar
But then I am not able to see the tables:

Code:
. jdbc showtable
Classpaths:
    file:/Applications/Stata/ado/base/jar/libstata-plugin.jar

Any idea what's going wrong?
