In the text of your question, you appear to be describing the sql_id and/or the hash_value.This is the hash of the text of the SQL statement and is what Oracle uses to determine whether a particular SQL statement already exists in the shared pool.

A Hash Value (also called as Hashes or Checksum) is a string value (of specific length), which is the result of calculation of a Hashing Algorithm. Hash Values have different uses. One of the main uses of Hash Values is to determine the Integrity of any Data (which can be a file, folder, email, attachments, downloads etc). Hash values can be thought of as fingerprints for files. The contents of a file are processed through a cryptographic algorithm, and a unique numerical value – the hash value - is produced that identifies the contents of the file. If the contents are modified in any way, the value of the hash will also change significantly. Dec 10, 2010 · A hash value is a result of a calculation (hash algorithm) that can be performed on a string of text, electronic file or entire hard drives contents. The result is also referred to as a checksum, hash code or hashes. Jul 06, 2020 · The term hash value refers to a piece of data, known as a value, given as the answer to a hash function. Hash functions are one and the same as hash algorithms, and perform the operation of turning a large set of data into a smaller set which represents the full set. This process is referred to as hashing and is often used in computer databases. May 22, 2019 · Hashes are the output of a hashing algorithm like MD5 (Message Digest 5) or SHA (Secure Hash Algorithm). These algorithms essentially aim to produce a unique, fixed-length string – the hash value, or “message digest” – for any given piece of data or “message”.

What is meant by Hash Code

This is a value that is computed from a base input number using a hashing algorithm. Essentially, the hash value is a summary of the original value. The important thing about a hash value is that it is nearly impossible to derive the original input number without knowing the data used to create the hash value. Here's a simple example: Input Number What is Hash Function? - Definition from Techopedia Mar 26, 2018 What Is Hashing? [Step-by-Step Guide-Under Hood Of Blockchain]

Significance of Hash Value Generation in Digital Forensic Digital forensics tools frequently use to calculate the hash value of digital evidence drive. MD5 and SHA hash function is used in digital forensic tools to calculate and verify that a data set Python hash() function - JournalDev Comparing hash is much faster than comparing the complete key values because the set of integers that the hash function maps each dictionary key to is much smaller than the set of objects itself. Also, note that if two numeric values can compare as equal, they will have the same hash as well, even if they belong to different data types, like 1
