sql - Cannot insert NULL values into database -


we use jpa load/persist our entities in prostges database. in 1 case must persist entity native query. heres code:

string sql = "insert recording (id,creationdate,duration,endtime,filemaninfocomplete,lastupdated,packagesdeletetime,rcinfocomplete,"                 + "rcrecordingkept,recordstate,recordingtype,starttime,tenantid,recordingnode_id,transcription_id) "                 + "values (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"; query query = getentitymanager().createnativequery(sql); query.setparameter(1, recording.getid()); query.setparameter(2, new date(), temporaltype.timestamp); query.setparameter(3, recording.getduration()); query.setparameter(4, recording.getendtime(), temporaltype.timestamp); query.setparameter(5, recording.isfilemaninfocomplete()); query.setparameter(6, new date(), temporaltype.timestamp); query.setparameter(7, recording.getpackagesdeletetime(), temporaltype.timestamp); query.setparameter(8, recording.isrcinfocomplete()); query.setparameter(9, recording.isrcrecordingkept()); query.setparameter(10,recording.getrecordstate() != null ? recording.getrecordstate().tostring() : recordstate.default); query.setparameter(11,recording.getrecordingtype()!= null ? recording.getrecordingtype().tostring() : null); query.setparameter(12,recording.getstarttime(), temporaltype.timestamp);         query.setparameter(13,recording.gettenantid());         query.setparameter(14,recording.getrecordingnode() != null ? recording.getrecordingnode().getid() : null);         query.setparameter(15, recording.gettranscription() != null ? recording.gettranscription().getid() : null);         query.executeupdate();

the insert works finde unless "getpackagesdeletetime" returns null. in case following message ist shown:

caused by: org.postgresql.util.psqlexception: fehler: spalte »packagesdeletetime« hat typ timestamp without time zone, aber der ausdruck hat typ character varying   hinweis: sie müssen den ausdruck umschreiben oder eine typumwandlung vornehmen.   position: 252

(ie:

error: column "packagesdeletetime" has type timestamp without time zone, expression of type character varying hint: must rewrite expression or typecast.

)

generated statement looks like:

insert recording(id,creationdate,duration,endtime,filemaninfocomplete,lastupdated,packagesdeletetime,rcinfocomplete,rcrecordingkept,recordstate,recordingtype,starttime,tenantid,recordingnode_id,transcription_id) values (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?) bind => [0c850391-cae9-4ac2-9381-b252167fa239, 2013-04-18 08:38:00.704, 20240, 2013-04-18 08:37:24.131, false, 2013-04-18 08:38:00.704, null, false, true, default, voice, 2013-04-18 08:37:03.891, f56251a7-44df-4151-aa0d-7c3fc538f621, null, null]

some tips how solve problem?

the corresponding field in entity has annotated with:

@column(nullable=true)

also check corresponding column in table allows null (has no not null constraint). if doesn't please post code of entity.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
