Description of problem:

In customers words
~~~
1. Can I use regular expressions to transform the values that come from the data source?
For example without regular expression:
Query: Select Field from Table
Result: "Hello World" # "# (" ($ "# ($!" #% $ = °°°:! [* [* "

With regular expression:
Query: Select ???? from Table
Result: "Hello World"

                ',[^,]+,') "REGEXPR_SUBSTR"
  FROM DUAL;
