I’m using jython 2.2.1, and jdbc 1.2 and connecting to a mssql 2000 database, writing the contents of an email to it. When I get to the body of the email which can be quite large sometimes I need to truncate the data at 5000 chars. Except mssql & jdbc gang up on me like school yard bullies, when i check the database loads of my data is missing, every time, with max chars = 256 chars.

I have checked the size of the field and it is set to 5000. what gives?

I am pretty sure it is related to jdbc, as the previous version used …. vb6 & odbc, without a hitch.

here is some code:

BODY_FIELD_DATABASE=5000  def _execute_insert(self):     try:         self._stmt=self._con.prepareStatement(\             'INSERT INTO EmailHdr (EntryID, MailSubject, MailFrom, MailTo, MailReceive, MailSent, AttachNo, MailBody)\              VALUES (?, ?, ?, ?, ?, ?, ?, cast(? as varchar (' + str(BODY_FIELD_DATABASE) + ')))')         self._stmt.setString(1,self._emailEntryId)         self._stmt.setString(2,self._subject)         self._stmt.setString(3,self._fromWho)         self._stmt.setString(4,self._toWho)         self._stmt.setString(5,self._emailRecv)         self._stmt.setString(6,self._emailSent)         self._stmt.setString(7,str(int(self._attachmentCount) + 1))         self._stmt.setString(8,self._format_email_body())          self._stmt.execute()         self._prepare_inserting_attachment_data()         self._insert_attachment_data()     except:         raise  def _format_email_body(self):     if not self._emailBody:         return ' '     if len(self._emailBody) > BODY_FIELD_DATABASE:         return self._clean_body(self._emailBody[:BODY_FIELD_DATABASE])     else:         return self._clean_body(self._emailBody)  def _clean_body(self,dirty):     '''used to clean =20 occurrence in email body that contains chinese characters        http://en.wikipedia.org/wiki/Quoted-printable'''     dirty=str(dirty)     return dirty.replace(r'=20','')

  1. Deleted my answer – it was totally wrong. Keeping it here though so comments & conversation hang around.

    EDIT:

    As you can read in the comments, here’s what happened:

    The data was being put into the database fine, but the MSSQL Query Manager could not display the Chinese characters.
