问题 I have a table containing date and events and users. There is event named 'A'. I want to find out how many time a particular event occurred before and after event 'A' in SQL Bigquery. The event A might appear multiple times. But it should count events only till it encounters another event A in both before and after condition. for Example, User Date Events 123 2018-02-14 X.Y.A 123 2018-02-12 X.Y.B 134 2018-02-10 Y.Z.A 123 2018-02-11 A 123 2018-02-01 X.Y.Z 134 2018-02-05 X.Y.B 134 2018-02-04 A

问题 I have a table TabA in BigQuery which has a column ColA and the column ColA has the following structure 1038627|21514184 and the table TabA has more than a million records. I used this to split into multiple columns SELECT ColA,FIRST(SPLIT(ColA, '/')) part1, NTH(2, SPLIT(ColA, '/')) part2 FROM TabA But for some reason, after certain rows the split seems to be not working properly. We are getting records like this, ColA part1 part2 1038627|21507470 1038627 21507470 1038627|21534857 1038627
