I wrote a example, how to do it
postgres=# do $$
x = plpy.SPIError('Nazdarek');
x.spidata = (100, "Some detail", "some hint", None, None);
raise x;
$$ language plpythonu;
ERROR: T1000: plpy.SPIError: Nazdarek
DETAIL: Some detail
HINT: some hint
CONTEXT: Traceback (most recent call last):
PL/Python anonymous code block, line 4, in <module>
raise x;
PL/Python anonymous code block
LOCATION: PLy_elog, plpy_elog.c:106
Time: 1.170 ms
Is it some better way?
I see a few disadvantages
1. sqlcode is entered via integer
2. it doesn't allow keyword parameters - so we can second constructor of
SPIError
some like
postgres=# do $$
def SPIError(message, detail = None, hint = None):
x = plpy.SPIError(message)
x.spidata = (0, detail, hint, None, None)
return x
raise SPIError('Nazdar Svete', hint = 'Hello world');
$$ language plpythonu;
The main problem is a name for this function.
