Hi All
I hope someone can help with a really frustrating problem I'm having.
I have the following models
class Output(models.Model):
title = models.CharField(u'Title', max_length=1024, db_index=True)
ingest_time = models.DateTimeField(u'Ingest timestamp'
, default=datetime.now())
output_date = models.DateField(u'Output date', blank=True, null=True
, db_index=True)
output_type = models.ForeignKey('OutputType')
status = models.ForeignKey('Status')
abstract = models.TextField(u'Abstract', blank=True, null=True)
class OutputMetadata(models.Model):
output = models.ForeignKey('Output')
field = models.ForeignKey('MetadataField')
value = models.TextField(u'Field Value')
If i run this:
outputs = Output.objects.filter(outputmetadata__value='History')
list(outputs) #to make the lazy query run
I get this error:
*** DatabaseError: ORA-06502: PL/SQL: numeric or value error: character
string buffer too small
ORA-06512: at line 1
(Note: Output.objects.all() does not return an error)
I took the generated sql and ran it in sqlplus and it works just fine. I
also took the generated sql, stripped out the nclobs from the selected
fields and ran it in cx_Oracle without django i.e.
cursor.execute('SELECT "OUTPUTSAPP_OUTPUT"."ID" FROM "OUTPUTSAPP_OUTPUT"
INNER JOIN "OUTPUTSAPP_OUTPUTMETADATA" ON ("OUTPUTSAPP_OUTPUT"."ID" =
"OUTPUTSAPP_OUTPUTMETADATA"."OUTPUT_ID") WHERE
UPPER(DBMS_LOB.SUBSTR("OUTPUTSAPP_OUTPUTMETADATA"."VALUE")) =
UPPER(\'History\') ORDER BY "OUTPUTSAPP_OUTPUT"."OUTPUT_DATE" DESC')
I get the same error.
I am running:
Django 1.4, cx_oracle 5.0.4 , Oracle 10.2 (which i am stuck with)
Has anyone seen anything like this or have any ideas where i can start
looking for a solution? I've been googling but to no avail :-(
Any pointers much appreciated
Charlie
