block size exceeds implementation restriction at JStatement::openCursor
-----------------------------------------------------------------------
Key: CORE-5598
URL: http://tracker.firebirdsql.org/browse/CORE-5598
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 3.0.2
Reporter: Jiri Cincura
I have a query that on one particular database throws:
2017-08-24T16:29:11.5140 (2704:0000000001620040) ERROR AT
JStatement::openCursor
I:\DOWNLOADS\BI2.FDB (ATT_16, SYSDBA:NONE, NONE,
TCPv6:::1/51084)
C:\Users\Jiri\Documents\devel\bin\Firebird-3.0.2.32703-0_x64\isql.exe:7116
335544381 : Implementation limit exceeded
335544388 : block size exceeds implementation restriction
On other databases (same structure, same plan produced) on the same
server (different data of course) it works fine. Backup & restore didn't
help. I can provide the database, but given it's a customer data it
needs to be handled as private data.
The minimum query I can replicate it looks like this:
with DAYS
as (select distinct(DR.F_DA_DATE)
from T_DAILY_RAW DR
)
select count(*)
from T_EMAILS_WEBDB_RAW EWR
inner join DAYS DR on DR.F_DA_DATE = EWR.F_EWR_SENT
inner join T_EMAIL_TYPE_DIM EMTD on EMTD.F_EMT_VALUE = EWR.F_EWR_TYPE;
And the plan is "PLAN HASH (EMTD NATURAL, JOIN (SORT (DR DR NATURAL), EWR
INDEX(IDX_EWR_SENT_A_TEMP)))".
