Finding Substring in Bigquery

问题

How to find substrings in Bigquery? I couldn't find any function which supports firing queries like 'Substring(Column_Name,3,7)'. Is there any way out to achieve the same functionality in Bigquery?

回答1:

#standardSQL
WITH yourTable AS (
  SELECT 'Finding Substring in Bigquery' AS Column_Name
)
SELECT SUBSTR(Column_Name, 9, 12)
FROM yourTable   

So SUBSTR(value, position [, length]) is for you to use

See String Functions for more

You can use substr e.g. substr(Column_Name,3,7)
