I don't do ODBC calls ;-)
Exactly how you handle this depends on your choice of
language and data access library. In general: you
want to send a SQL string "SELECT
get_square(integer_value)", where "integer_value" is
determined at run time. What you get back will be a
result set with one row and one column. If you want
to refer to the column by name, you can specify a name
by adding the alias "AS my_column_name" to the SQL
string.
The rest you can get from the documentation for your
environment, particulary about how SQL queries and
result sets are handled.
