Question

I’m using VB.NET with the MySQLConnector, I have an ID column with differents values, i.e:

101
102
201
202
203
302
304
305
306

I want to select all the values that start with “3” and then, select the MAX of them, in this case, “306”

Any suggestion?
Thanks

select max(id) from Data
where left(cast(`id` as char(10)), 1) = '3';
