In PostgreSQL, regex (regular expressions) enables powerful pattern matching for string data, useful for filtering, searching, and manipulating text. Regex allows you to identify specific patterns within text fields, making it ideal for data validation, cleaning, and advanced searches within your data...
Regex pattern matching tools such as those in the Unix utility and the popular scripting language commonly include extended functionality beyond the classical definition of regular expressions. The main focus is on as studied by C芒mpeanu, Salomaa and Yu [1]. We offer an additional pumping lemma...

This topic describes the pattern matching supported by PolarDB for PostgreSQL (Compatible with Oracle). Note If you have pattern matching needs that go beyond this, consider writing a user-defined function in Perl or Tcl. While most regular-expression searches can be executed very quickly, regula...
Scala’s pattern matching provides deep inspection and decomposition of objects in a variety of ways. It’s one of my favorite features in Scala. For your own types, you can follow a protocol that allows you to control the visibility of internal state and how to expose it to users. The ...
The purpose of this KB is to provide few examples on how to use the regex pattern matching in Bamboo for matching the branch names. Environment This has been tested on Bamboo 9.6.4 but the solution will work for other supported version of Bamboo. ...
