Answer 1

The character value you are trying to insert needs 4
bytes but column is limited to 2 (value too
large...).
Try instead:
create table test (text varchar2(4));
and retry the same insert statement.because i want to create test db so the table schema must same as production table schema,so i cant change the table schema.
