SQL computed column?

Question

MySQL

Guys, according to the results of the sql query, a calculated column appears, that is, a virtual column that is not physically stored in the table, with an Int value, for example 7. Is it possible to use this value on the client, namely in the form of a table of 7 rows? Anyone who has experienced this, please respond.

Answer 1

If there is a column in the query result, then it can be obtained from the ResultSet and used as you like.
