Hello,
I think I've tripped over another mysq_fdw bug. I've filed a bug
report
on github already but just in case the problem is w/ my query I
figured
I would post it here in case someone sees something obvious.
The error message I get is: null value in column "location" violates
not-null constraint.
The DDL is here: https://github.com/EnterpriseDB/mysql_fdw/issues/71
For the record I know top posting is a crime against god and
humanity
but I feel justified because this post is not directly related
to the
original. So there! Granted it's in the same milieu; and yes this
current sentence exists for the sole purpose of me being able to
use the
word milieu because the opportunity to use it is so few and far
between.
INSERT INTO series (cid, day, title, description, location,
duration,
can_join)
SELECT
cid,
row_number() OVER (PARTITION BY cid ORDER BY lower(duration)),

Regards,
So what do you get when you do?:
SELECT
cid,
title,
description,
can_join::BOOLEAN,
(SELECT label FROM _locations WHERE loc=location) AS location,
('[' || starts || ', ' || (starts + INTERVAL '4 HOUR') ||
']')::TSTZRANGE AS duration
FROM
_series
);

I get rows of data, location and all.
And when you do?:
SELECT
cid,
row_number() OVER (PARTITION BY cid ORDER BY lower(duration)),
title,
description,
location,
duration,
can_join
FROM (
SELECT
cid,
title,
description,
can_join::BOOLEAN,
(SELECT label FROM _locations WHERE loc=location) AS location,
('[' || starts || ', ' || (starts + INTERVAL '4 HOUR') || ']')::TSTZRANGE AS duration
FROM
_series
) AS v
Before I answer your second query question I need to revise my response to the first. Yes the first query runs w/o an error message but the bit about "rows and all" was not entirely correct. Out of 313 rows only the first row had a location. The other 312 rows have NULL in the location column which is not supposed to happen. To verify this I changed the table names and removed the PostgreSQL transformations (i.e., use of || and :: for casting) and ran the query against the MySQL database; it returned 313 rows of data, location and all.
Now that I've cleared that up.
Your second query also runs w/o any error messages but like the first only the first row has a non NULL value in the location column.
