![]() You’re going to get 0 returned if you’ve run out of numbers (as far as the MIN/MAX algorithm is concerned, at least).This shouldn’t be a problem as long as you use it from the outset If you happen to have two numbers in the table, 5 then you’re going to get no results.If no numbers exist in the table, it’ll start at 101. If it is, it takes one number below the minimum. What it does is takes the number above the largest number in our table, unless that number is already our maximum (65535). This will generate a new number between 5 which will not be in the id_sensor column of the sensors table. Here’s the query: SELECT IFNULL(IF (MAX(id_sensor) >= 65535, MIN(id_sensor) - 1, MAX(id_sensor) + 1), 101) new_id FROM sensors That said, it’s going to cover 99% of usecases. because you don’t want people to predict the next number, for security reasons) then this isn’t the solution for you. Ok, so this doesn’t generate truly random numbers. You’ll have to run the query possibly hundreds of thousands of times to get a result. data.value field: random float numbers from given range (0.00-100.00 for example) data.id is autoincrement, no need to care about that. This will be a problem when you’re generating a number between 1 and a million but already have many rows in the table. How can I fill it with 1000000 million rows in MySQL Requirements: data.datetime field: random timestamps but only from one year. As such, you’ll need to run the query multiple times until you get a result. Some of the other solutions are OK but will return no results when the number it generates happens to already be in the table. The accepted solution is totally wrong since, as the comments elude to, it’s comparing a string. You may have already come across this StackOverflow post. The “optimal” solution below is about as good as it gets. Hopefully that helps one person sometime in the future.You have a list of numbers in a table and you want to generate a new number, between a set of two values, which isn’t already present in the table. Where it appears as ‘’ this is ‘+’ with no space between. ![]() Note: the syntax above uses the ’ symbol. Mysql> UPDATE cscart_users SET password=‘insert-your-md5-hashed-pw-here’, salt = ‘’ WHERE user_id=‘1’ ![]() (that’s not my password, that’s just random banging on the keyboard) Password = afsdqk455iuetrhsaiusgfhw984qtru9udfgd I suggest copying the output from this command to a text editor (or something similar) that allows for an infinite width. The output is wide and difficult to read in a terminal. You should see a table with the following headers “Field”, “Type”, “Null”, “Key”, “Default”, “Extra”. This is not necessary, but will confirm that you are in the right place. If you are interested… view the cs cart users schema (i think that’s what it’s called) SELECT RAND()(25-10)+10 The formula above would generate a random decimal number > 10 and < 25. You should see the CS Cart DB that you created during CS Cart install. To create a random decimal number between two values (range), you can use the following formula: SELECT RAND()(b-a)+a Where a is the smallest number and b is the largest number that you want to generate a random number for. If you are not already logged into MySQL then login. Go here and generate a MD5 hash for your new password: $ sudo systemctl unset-environment MYSQLD_OPTS Reverting Database to its normal settings Mysql> ALTER USER IDENTIFIED BY ‘new_password’ $ sudo systemctl set-environment MYSQLD_OPTS=“–skip-networking -skip-grant-tables” Step 1: Reset MySQL Root Password (only if necessary) Note: Some of these commands are for validation and can be skipped if you are comfortable with MySQL. Private server - Full admin - No GUI Tools Posting this here for anyone that might happen to need this in the future. A random script attack is possible, but if so then I have concerns with the security of CS Cart? I am running the latest copy of Ubuntu (as of July 1 2023) with a fully updated LAMP install. My site is accessible to the public but google hasn’t indexed it yet and I don’t have any customers on it. It’s possible that I was hacked, and I will continue to investigate that, but other than the password not working I do not see any other signs of unauthorized access. If anyone has a theory as to why my password suddenly stopped working, please let me know. I am presently developing on this server and hadn’t yet configured email (might have helped with password reset). ![]() For whatever reason the password for my admin account stopped working.
