SQL pattern matching enables you to use _ to match any single character and % to match an arbitrary number of characters (including zero characters). In MySQL, SQL patterns are case-insensitive by default. Some examples are shown here. Do not use = or <> when you use SQL patterns. Use...
Pattern-matching functions enable us to search and filter string data based on specific patterns. PostgreSQL provides us with pattern-matching functions, which we can use to find strings matching a pattern or perform complex searches within a column. In this tutorial, we’ll illustrate various patt...

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...
In proposed system the user generated SQL Queries are checked whether they are SQL injected or not using SQLMAP tool and AIIDA-sql techniques. Then the user generated SQL queries are checked by applying static pattern matching algorithm. In the new system, if any form of new anomaly occurs, ...
