It looks like you're trying to construct an SQL injection payload. The snippet you've provided appears to be an attempt to manipulate a SQL query using a time delay function (PG_SLEEP(15)) commonly found in PostgreSQL databases.
Here’s a breakdown of the parts of this query:
-
20-1 OR 88=: This looks like the beginning of a conditional statement. It suggests you're trying to alter the logic of the SQL execution to force the database to return true for the rest of the query. -
(SELECT 88 FROM PG_SLEEP(15))--: This part seems to be attempting to create a subquery that, when executed, would pause for 15 seconds due to thePG_SLEEP()function. The--indicates a comment in SQL, meaning anything after it would not be executed, effectively ignoring whatever valid SQL follows.
If you're looking for assistance with SQL queries, database management, or security practices, please provide some context or clarify your request, and I'll be happy to help! Otherwise, discussing or attempting SQL injection can lead to illegal and unethical actions, which I do not support.
