SPLIT_PART
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The SPLIT_PART() function splits a string into substrings and retrieves the nth part, starting from 1.

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:
