如何获取 SQL、Bigquery 中前一天的记录数？

Question

As written in the question, I'm trying to get a count of all records from the previous day in Bigquery. My column for the times is ingest_time. I've tried the query below, but it doesn't work in Bigquery. I'm using standard sql in bigquery for this question.

where 
  date(ingest_time)=date(date_sub(now(),interval 1 day));

Answer 1

Try the following for standard SQL:

SELECT COUNT(*) AS cnt
FROM yourTable
WHERE DATE(ingest_time) >= DATE_ADD(CURRENT_DATE(), INTERVAL -1 DAY);

Answer 2

Just an addition to Tim's answer, you can use COUNTIF operator:

select 
  COUNTIF(DATE(ingest_time) >= DATE_ADD(CURRENT_DATE(), INTERVAL -1 DAY)) as cnt 
FROM yourTable
