I try to implement a order by with the attribute "Nachname" in english "surname". But in my try, the object k ist not found.
I do not understanding, how I can use the oder_by in pony orm
sel = select((k.kuId, a.adressid, k.nachname, k.vorname, k.email, k.telefon, a.kunde, a.ort, a.strasse,
a.plz, a.land, a.adresszusatz,
a.staat, a.art) for a in Adresse for k in Kunde if k.kuId == a.kunde.kuId and a.art == 1
).order_by(lambda: k.nachname )
How I can order my selection by k.nachname?
Greetings niesel
Pycharm can't handle the pony orm syntax and higlights the k in order_by(k.nachname) as unknown reference. The answer for my question is:
sel = select((k.kuId, a.adressid, k.nachname, k.vorname, k.email, k.telefon, a.kunde, a.ort, a.strasse,
a.plz, a.land, a.adresszusatz,
a.staat, a.art) for a in Adresse for k in Kunde if k.kuId == a.kunde.kuId and a.art == 1
).order_by(lambda: k.nachname )

How to use date condition in Symfony (doctrine + oracle) ?
I have trying
$qb = $this->createQueryBuilder('la')
->select('la.id')
->andWhere("la.dateCreated >= TO_DATE(':a', 'yyyy-mm-dd')")
->setParameter('a', '2020-09-01')
->getQuery();
However is error: the query defines 0 parameters and you bound 1
Any Ideas?
In your code, I don't think there should be quotes on ':a', I'd put :
TO_DATE(:a, 'yyyy-mm-dd')
Beside, how about :
$qb = $this->createQueryBuilder('la')
->select('la.id')
->andWhere("la.dateCreated >= :a)
->setParameter('a', '2020-09-01')
->getQuery();
This is my query & I'm getting error divisor is equal to zero, I know i need to build this as a case statement just tried a few things and cant get it to work, thanks in advance.

The only dividing in this mess is here:

If you don't want to divide with zero, you'll have to handle it.
For example, use DECODE (or CASE) and - if you want to get 0 as the result, divide with a very large number (e.g. 1E99)
DB:
I'm trying to bring back data only when All of the ReviewItems meet the condition of ReviewItemStatus==3. This works.
Problem: But then I want to narrow the scope of All to all ReviewItems where ReviewerID==1000
// I want ALL groupAccountLinks only for ReviewerID==1000 and AccountID
// 0) (and thus ReviewItems) for Account Charlie have ReviewItemStatusID==3
var xx = Accounts.Where(acc => acc.GroupAccountLinks.All(gal =>
// do ANY of the (1) associated reviewItems contain ri.ReviewItemStatusID == 3
gal.ReviewItems.Any(ri => ri.ReviewItemStatusID == 3)
// This doesn't work
//&& ri.Review.ReviewerID == 1000
)
&& acc.AccountID == 1002 // Charlie
);
Will be going against EF4.1 Currently testing using Linqpad and LinqToSQL test db.
You have && Condition .So, I think your table not have all AccountId=1002 and All ReviewItemStatusID =3 . So Change && condition to || condition.
The first thing I would do would be to take the && acc.AccountID == 1002 off and make sure that you're getting the entire unfiltered set of Accounts that have a ReviewItem in status 3. If that looks good try doing your filter this way:
var xx = Accounts
.Where(acc => acc.GroupAccountLinks
.All(gal => gal.ReviewItems
.Any(ri => ri.ReviewItemStatusID == 3))
.FirstOrDefault(acc => acc.AccountID == 1002);
Thanks to Jesse, Slauma and RemeshRams which lead me to this:
var xxx = Accounts.Where(
// do All Accounts satisfy condition
u => u.Accounts.All(
// do All GroupAccountLinks (and thus ReviewItems) for Account meet the condition of ReviewItemStatusID==3
acc => acc.GroupAccountLinks.All(
// for ReviewItems where ReviewerID==1000, do they All have ReviewItemStatusID==3
gal => gal.ReviewItems.Where(
ri => ri.Review.ReviewerID == 1000)
.All(
ri => ri.ReviewItemStatusID == 3
)
// Make sure there are some ReviewItems
&& gal.ReviewItems.Any()
)
)
);
positions = {
--table 1
[1] = {pos = {fromPosition = {x=1809, y=317, z=8},toPosition = {x=1818, y=331, z=8}}, m = {"100 monster"}},

}
tb = positions[?]--what need place here?
for _,x in pairs(tb.m) do --function
for s = 1, tonumber(x:match("%d+")) do
pos = {x = math.random(tb.pos.fromPosition.x, tb.pos.toPosition.x), y = math.random(tb.pos.fromPosition.y, tb1.pos.toPosition.y), z = tb.pos.fromPosition.z}
doCreateMonster(x:match("%s(.+)"), pos)
end
end
Here the problem, i use tb = positions[1], and it only for one table in "positions" table. But how apply this function for all tables in this table?
I don't know Lua very well but you could loop over the table:
for i = 0, table.getn(positions), 1 do
tb = positions[i]
...
end
Sources :
http://lua.gts-stolberg.de/en/schleifen.php and http://www.lua.org/pil/19.1.html
You need to iterate over positions with a numerical for.
Note that, unlike Antoine Lassauzay's answer, the loop starts at 1 and not 0, and uses the # operator instead of table.getn (deprecated function in Lua 5.1, removed in Lua 5.2).
for i=1,#positions do
tb = positions[i]
...
end
use the pairs() built-in. there isn't any reason to do a numeric for loop here.
for index, position in pairs(positions) do
tb = positions[index]
-- tb is now exactly the same value as variable 'position'

I'm using the pg gem to talk to PostgreSQL from Ruby. Is there a
better way to check if there are no results than using res.ntuples == 0?
conn = PGconn.connect config
cmd = "select * from labels inner join labels_mail using(label_id) " +
"where labels_mail.mail_id = $1 and labels.name = $2"
res = conn.exec(cmd, [mail_id, mailbox])
if res.ntuples == 0 # <=== is there a better way to check this?
cmd = "insert into labels_mail (mail_id, label_id) values ($1, $2)"
conn.exec(cmd, [mail_id, label_id(mailbox)])
end
ntuples, a typo? It is faster and concise to use zero? than == 0
if res.num_tuples.zero?
