BLOB,NCLOB,BFILE doubts

Question

Sir
Probably its look a basic question to this forum.And I am also accepting I know very little about SQL.I am basically preparing for exam 1z0-051.and want to clear a doubt.
How to Insert a BLOB,CLOB,NCLOB,BFILE field?
a create statement is enough to create a table but how do i inser values for this field?do i need any third party software to do so?
Our OAEC teacher is claiming insertion and updation is not done by sql / sql*plus or by any sql commands.its all left to the third party software.
What I believe (I know its not important for this group but still I am explaining it to clear my doubts) :
May be a third party software is required to convert it into byte stream but actual insertion is done by SQL.
thanks in advance
