SPLIT_PART
In snowflake how to split a given string at a specified character and returns the requested part. In Snowflake, the function that is equivalent to MySQL’s SUBSTRING_INDEX() is SPLIT_PART(). The SPLIT_PART() function in Snowflake is used to extract a specific part of a string based on a delimiter. It takes three arguments:
- The original string
- The delimiter
- The position of the part to be extracted
The syntax of the SPLIT_PART() function is as follows:
SPLIT_PART(string, delimiter, field)
For example, if you have a string ‘a,b,c,d’ and you want to extract the substring before the second comma, you would use the following query:
SELECT SPLIT_PART('a,b,c,d', ',', 1)
The function would return ‘a’ because it’s the first part of the string before the first comma.
Another example, if you have a string ‘https://www.freshers.in/tags/snowflake/‘ and you want to extract the domain from the URL, you would use the following query:
SELECT SPLIT_PART('https://www.freshers.in/tags/snowflake/', '/', 3)
The function would return ‘www.freshers.in’ because it’s the 3rd part of the string after the first two slashes
It’s important to note that the delimiter is case-sensitive and the function only works with the specified position of the delimiter.
In summary, the SPLIT_PART() function in Snowflake allows you to extract a specific part of a string based on a delimiter, which can be useful for parsing strings with a specific structure, and it’s the exact duplicate function of MySQL’s SUBSTRING_INDEX()
