How can I insert into a BLOB column from an insert statement in sqldeveloper?

Question

Is it possible to insert into a BLOB column in oracle using sqldeveloper?

i.e. something like:

insert into mytable(id, myblob) values (1,'some magic here');

Answer 1

To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next:

insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw('some magic here'));

It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column.
