The most effective way to stop this is to use (Prepared Statements). Instead of building a query string with user input, you use placeholders.

It looks like you've included a snippet of code in your query. Specifically, this is a "Boolean-based" or "Error-based" blind injection attempt using Oracle-specific syntax like XMLType and CHR codes to extract information from a database [1, 2]. The most effective way to stop this is

The string you provided is designed to trick a database into executing a command by appending it to a legitimate search term ( KEYWORD ). It uses the SELECT CASE statement to test if a condition (like 9298=9298 ) is true, which helps an attacker confirm that the database is vulnerable [2, 3]. 2.
