我正在使用Spark SQL3.1使用join运行一些查询,其中两个表中相同的列可以包含null值,例如: select ...join band a.col_without_nulls = b.col_without_nulls 但是,当查询null值时,查询不能在on条件下工作。我还尝试过: select ...join b
on a.col_with_nulls is no
我在BigQuery中有以下查询: #Standard SQL
FROM `Table_1`
LEFT JOIN `Table_2` ON (timestamp BETWEENTimeStampStart AND TimeStampEnd) 但我得到以下错误: Error: LEFT OUTER JOIN cannot be used without a conditionthat is an equality of fields from both sides of the join
我的SQL查询有任何人可以看到的问题吗?我正在处理三个表,名为SHPMT、SHPMT_TRUCK和Ship_Day,预期的输出应该是Location、Ship_Day、Count_With_Truck和Count_Without_Truck。COUNT(SHPMT_TRUCK.Truck_ID) AS Count_With_Truck,FROM SHPMT
WHERE ORIGIN.Typ_Cd =
