Specifically, this is a attempt using a "group by" error-based technique.
It uses CONCAT and RAND() to generate a predictable error. The 0x7170786271 and 0x7176706a71 are hexadecimal "markers" (spelling out "qpxbq" and "qvpjq") that allow the attacker to easily find the injected data within the server's error logs. Specifically, this is a attempt using a "group
