Eg: SELECT name, address, random_number FROM users I dont have to store this n I am wondering if there is a function in MySQL like generate_series which usually takes in a starting integer value, an ending one and an increment and returns a array of all the values including and between the start and the end. Closest thing is AUTO_INCREMENT, which can help you construct the table. If the AUTO_INCREMENT column is part of multiple indexes, MySQL generates sequence values using the index that begins with the AUTO_INCREMENT column, if there is one. So there are so numbers available between the ranges. SQL sequences are used to generate unique numbers automatically for things like primary keys and IDs. (If you have a table with a sequential id column and never delete rows from it, you can just select the id column from that table instead of creating a new numbers table). Then, there is a view to select some records from another table with account numbers between the from-number and the to-number. 17 I want to generate a unique random integer (from 10000 to 99999) identity just by clean mySQL; any ideas?
