Something like: 6KMPOATg6Y5TbuEZlD59DpĪny ideas on how to do this? Ideally with only (Netezza) SQL-code or functions.A Netezza Dialect(nzalchemy) for SQLAlchemy Scope So instead, I would like to create a human-readable identifier by, for example, converting this 128-bit unicode string to a base-62 string, containing only alphanumeric characters (0-9, a-z, A-Z). I'm afraid this will cause trouble when I start combining this date with tables from other systems. This has more than enough entropy, but it becomes an unreadable mess of unicode characters: oð8^GþåíOpJ This is perfectly readable, but it has only 64-bits of entropy. So, on Netezza I can easily do select hash8(123456) as id

#Ibm netezza sql reference 64 bits

According to this table, 64 bits is not enough to avoid hash collisions with this number of records. I want this identifier to have more than 64 bits of entropy, as the column may contain (in time) more than 10^12 different records, and I want to avoid hash collisions. I'm working on IBM Netezza/PureData and I want to add an identifier column to a table containing billions of new records every day, so that I can track each record as it travels through different tables and systems.
