You need a WHERE clause in order to restrict the number of rows. 
Something like:

SELECT __IDB_INTERNAL last_value FROM TEXT('id') IN TABLE asUser_seq
FROM asUser_seq WHERE something=1

Unfortunately, there's a bug in the expression evaluator that results 
in there always being at least two rows returned unless you also add 
the row selector to the column selection (fixed in the next release).

SELECT something, __IDB_INTERNAL last_value FROM TEXT('id') IN TABLE 
asUser_seq
FROM asUser_seq WHERE something=1
