Retrieving a table count of rows using the COUNT(*) aggregate function in MySQL is a straight-forward query. What if I told you that with the MySQL Shell, there are actually 3 possible ways – between 2 Shell modes (\sql and \py) – to retrieve a table row count? Would you be interested in knowing about them? Honestly, one of the queries will not surprise you in the least bit, as you are likely already using it. However, the other 2 queries – in this context – are specific to MySQL Shell Python mode. You can likely execute these queries in Javascript Mode. However, I am not versed in Javascript programming nor MySQL Shell Javascript mode so those queries are not covered here.
