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                 |
+--------------------+----------------------+
