As per recent data, there is an error when querying the gsod_noaa dataset because of the table's naming. Here's the correction: SELECT DATE(CAST(year AS INT64), CAST(mo AS INT64), CAST(da AS INT64)) AS date, (SELECT ANY_VALUE(name) FROM `bigquery-public-data.noaa_gsod.stations` AS stations WHERE stations.usaf = stn) AS station_name, -- Stations may have multiple names prcp FROM `bigquery-public-data.noaa_gsod.gsod*` AS weather WHERE prcp < 99.9 -- Filter unknown values AND prcp > 0 -- Filter stations/days with no precipitation AND CAST(LEFT(_TABLE_SUFFIX,4) AS int64) >= 2018 ORDER BY date DESC -- Where has it rained/snowed recently LIMIT 10

Running this lab today (20211130) is causing issues since in the noaa_gsod dataset there are two tables "gsod2020-2021-11-28T21_02_22" and "gsod2020-2021-11-28T21_02_43" that are breaking the "CAST(_TABLE_SUFFIX AS int64) >= 2018" function.

The queries against the public dataset fail as is, because there seems to be extra snapshots in the dataset and you can't cast the table suffix as a timestamp

Some issues with the ability to deal with this due to the public data set having table suffixes which failed the data conversion to bit64
