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?

BigQuery substring after character For this, the first step is to use the STRPOS() function inside the SUBSTR() function to define the precise location of the @ character in the string. Afterwards we add 1 to the substring to indicate where the beginning is.
BigQuery STRPOS to Find Character in StringThe STRPOS function tells us which point in the string can we find a specific character (or text). If there are multiple occurrences of the text, BigQuery will give the position (or index) of the first occurrence. If we cannot find the text, the result is 0 .
1) Trimming FunctionTRIM (value1[, value2]): It removes all the leading and trailing characters that match value2. If no character is specified, whitespaces are removed by default.
CHAR_LENGTH. Returns the length of the STRING in characters.
#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
