The SPLIT_PART() function splits a string into substrings and retrieves the nth part, starting from 1.

SELECT split_part('a,b,c', ',', 2);
create.select(splitPart(val("a,b,c"), ",", 2)).fetch();

The result being

+------------+
| split_part |
+------------+
| b          |
+------------+

Dialect support

This example using jOOQ:

splitPart(val("a,b,c"), ",", 2)

Translates to the following dialect specific expressions:
