REGEXP_REPLACE
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The REGEXP_REPLACE() function searches a string for a regular expression pattern, and replaces all or the first occurrence of that string.
Vendors offer different versions of this function, so jOOQ standardises them as two synthetic functions:
-
REGEXP_REPLACE_ALL() -
REGEXP_REPLACE_FIRST()
For example:
SELECT
regexp_replace_all('hello', 'l', ''),
regexp_replace_first('hello', 'l', '');
create.select(
regexpReplaceAll(val("hello"), "l", ""),
regexpReplaceFirst(val("hello"), "l", "")).fetch();
The result being
+--------------------+----------------------+ | regexp_replace_all | regexp_replace_first | +--------------------+----------------------+ | heo | helo | +--------------------+----------------------+
