I think you could find your answer in this statement from the MySql documentation

Primary Key Generation Using SQL Server's IDENTITY. In SQL Server you can use the IDENTITY keyword to indicate that a primary-key needs to be auto-generated. The following example shows a common scenario where the first primary key value is 1, and the increment is 1.

The ID that was generated is maintained in the server on a per-connection basis. This means that the value returned by the function to a given client is the first AUTO_INCREMENT value generated for most recent statement affecting an AUTO_INCREMENT column by that client. This value cannot be affected by other clients, even if they generate AUTO_INCREMENT values of their own. This behavior ensures that each client can retrieve its own ID without concern for the activity of other clients, and without the need for locks or transactions.

Convert AWK command to sqlite query

sql,awk,sqlite3

Make sure you make a backup of the private key. Now load up PuTTYgen, click “Conversions” at the top, and click “Import key.” Navigate to the key you downloaded from your service panel, choose it, and click “Open.” It’ll fill up the window with information about the private key you just imported. PuTTYgen is an key generator tool for creating SSH keys for PuTTY. It is analogous to the ssh-keygen tool used in some other SSH implementations. The basic function is to create public and private key pairs. PuTTY stores keys in its own format in.ppk files. However, the tool can also convert keys to and from other formats. Launch the program and click on the Load button and select your PuTTY's key file, which normally ends with.ppk extension. Enter the key's passphrase if prompted. Details of the imported key will be displayed. Go to Conversions → Export OpenSSH key from the menu. Save your converted key. If you need to connect to a server that only accepts public keys for SSH connection this is a step-by-step tutorial on how to use PuTTY to establish a secure connection via Public keys. The idea is to let the server store a public key, and your computer (PuTTY) client will provide a private key. Putty generate ppk from private keys.
