我在BigQuery中有一个表TabA,它有一列ColA,ColA列有以下结构

1038627|21514184

而TabA表有超过一百万条记录.我用它来分成多列

SELECT ColA,FIRST(SPLIT(ColA, '/')) part1,
       NTH(2, SPLIT(ColA, '/')) part2
FROM TabA

但由于某种原因,在某些行之后,拆分似乎无法正常工作.

我们得到这样的记录,

     ColA            part1   part2
1038627|21507470    1038627 21507470     
1038627|21534857    1038627 21507470     
1038627|21546455    1038627 21507470     
1038627|21577167    1038627 21507470

It his happening on a random basis. Not sure where is there error.

SELECT COUNT(*) FROM TabA - returns say 1.7M records

SELECT ColA,FIRST(SPLIT(ColA, '|')) part1, NTH(2, SPLIT(ColA, '|')) part2 FROM TabA - returns 1.7M records with the wrong split

SELECT FIRST(SPLIT(ColA, '|')) part1, NTH(2, SPLIT(ColA, '|')) part2 …
