Java - SQL Exception column doesn't have default value -

i've got prepared statement: (i not want insert data column_1)

pstmt = artclslctcon.preparestatement("insert `temp_articles` (`title`, `author`, `author_id`, `type`, `wfurl`, `intro`, `intro_image`, `main_image`) values (?, ?, ?, ?, ?, ?, ?, ?)"); 

with error:

java.sql.sqlexception: field 'content_1' doesn't have default value 

my database looks this:

there lots of image , content columns (17 of each).

is there anyway keep default value of image_n , content_n columns none?

phpmyadmin says:

the columns don't have default value , don't support null values, impossible insert data in if don't provide value (as you're doing). define valid default value these columns or make support null values.
