Add support for a SQL REPLACE(in, search, replace) function
-----------------------------------------------------------
Key: DERBY-5597
URL: https://issues.apache.org/jira/browse/DERBY-5597
Project: Derby
Issue Type: Improvement
Components: SQL
Affects Versions: 10.8.2.2
Reporter: Lukas Eder
I don't know any other database that lacks this type of function (even SQLite
has it):
REPLACE(in, search)
REPLACE(in, search, replace)
But according to the Derby docs, this doesn't exist in Derby:
http://db.apache.org/derby/docs/10.8/ref/rrefsqlj29026.html
It would be quite simple to implement, I guess. Yet really useful for many
people. Some documentation examples from other databases:
