QUESTION
I'm trying to handle a legacy database with doctrine. There is many fields in different tables that are codes which refer to a unique code table CHOIXCOD. This table relies on two keys. The key (CC_CODE) that corresponds to the value in the linked fields, and a type code (CC_TYPE) identifying which field the first key is targeting.
So i used Doctrine Inheritance on an abstract entity targeting this code table, and created as many children entities as there is difference types. What i understand is that Doctrine will make snippets of CHOIXCOD on the CC_TYPE field, and in each snippet, CC_CODE will be the key column.
But, when all $ccCode are differents all works fine, but, in one table having multiple references to CHOIXCOD, if two fields referencing CC_CODE have the same value, Doctrine will give them the same CC_TYPE value, resulting in targeting the wrong entity, crash, 500 error, project being late, me being fired.
So here is the mother entity.
...ANSWER
Answered 2021-Feb-07 at 22:01Ok, so after struggling with that problem for a while, I understood that Doctrine stores a two dimensions array in order to request joins (1-entity joined, 2-id of entity instance). I suppose the aim is to limit the number of request done for a yet known instance.
In our case, inheritance, the first dimension of the array is named with the extended entity so as I had the same ids for the same first dimension name that was messed up from the beginning. Setting the discriminator as @Id could have solved this problem but Doctrine does not automatically set the discriminator value in object, throwing an id missing exception.
So the solution I kept is to put an annotation on foreign key that specifies discriminator value this foreign key corresponds to. When encountered in doctrine postLoad event, I request the database on foreign key value (the primary key corresponding being CC_CODE) and discriminator (the value of CC_TYPE) in annotation, and put it into an another field.

QUESTION
I want to use z3py to illustrate the following genealogy exercise (pa is “parent” and grpa is “grand-parent)
pa(Rob,Kev) ∧ pa(Rob,Sama) ∧ pa(Sama,Tho) ∧ pa(Dor,Jim) ∧ pa(Bor,Jim) ∧ pa(Bor,Eli) ∧ pa(Jim,Tho) ∧ pa(Sama,Samu) ∧ pa(Jim,Samu) ∧ pa(Zel,Max) ∧ pa(Samu,Max)
∀X,Y,Z pa(X,Z) ∧ pa(Z,Y) → grpa(X,Y)
The exercise consists in finding for which value of X one has the following:
∃X grpa(Rob,X) ∧ pa(X,Max)
(The answer being: for X == Samu.) I would like to rewrite this problem in z3py, so I introduce a new sort Hum (for “humans”) and write the following:

I am trying to write a sql in bigquery and I have a requirement to filter records based on a group by column and another column in the table what I mean is I want to check if the group by column(column name:mnt) has more than one row then I have to check if col2 (col name: zel) value, then I have to apply a filter saying col2 ='X' and only pass that record else pass i.e dont filter the records if the col1 has only distinct one value per group
So I have written a sql to do this I have used row_number as well as rank , dense rank function but I noticed the value of rank and dense rank and row number functions return same value for a group
Please see the below code

In my project, I use PostgreSQL and Hibernate to connect to my ZUL and all that noise. The connection I am trying to do is, in a Facebook manner, an user entry whose ID appears in several Posts and Comments. This calls for a OneToMany and a ManyToOne kind of deal. This is my first time doing these kind of connections in ZK and Hibernate, and I would appreciate it if I were pointed out where I'm wrong.
Here are the errors that pop out several times:

I am migrating to Maven , on Netbeans, an old project based on Java 1.7 that runs on glassfish 3, the project uses Hibernate 4.3.1, Spring 3.0.6, and ZK 6 for the interface part.
I managed to add all the former jars to the POM.xml I also created the beans.xml file. So the project compiles without errors, the project also starts ok and the first page ( the login page ) opens correctly. In the logs I can see all the database access working fine, so the domains and businessImpl are also running fine, but when I loggin, the page that should load fails to show with the following error :
...ANSWER
Answered 2019-May-08 at 22:16Solution Found, the issue coming from the EL binding anotations from ZK, I checked the pom.xml for the versions and found inconsistency. Even if the non maven project runs fine with the zk libraries versions as they were specified in the pom, i changed the ZKEL dependency to a more recent one and it worked. thanks Hawk for putting me on rigth track.

Answered 2019-Mar-15 at 17:21Here you go. Use the class named CivicInfo, add it to your Project.
If you're reading from a File or Stream, open the File or Stream (sample provided) or directly pass the JSON Object (the string) to the JsonConvert.DeserializeObject() method:
If you're reading from an existing Stream (i.e., from the Web), use only the StreamReader.

I am trying to populate a datatable with information gathered from my API. Currently I am able to populate the table with all the rows I need however they do not seem to be attaching to the table, other than the first result. This results in the datatable only showing 1 entry if any search is made. It also says "Showing 1 to 1 of 1 entries" at the bottom

...ANSWER
Answered 2018-Aug-07 at 01:25Here is updated code Fiddle/5.
You are initializing your Datatable too soon: before you added all your rows. You need to init it after all data is appended to the DOM HTML.
