AutoGenerator | Auto Generate Data Persistence Layer Code By Table Create | SQL Database library

I fixed. Problem was in: Data truncation: Data too long for column 'column_name'. I just make: jdbcCompliantTruncation=false in my application.properties

This is because compiler already implements equality methods for records. Check Value equality of records:

To implement value equality, the compiler synthesizes the following methods:

• An override of Object.Equals(Object).

• This method is used as the basis for the Object.Equals(Object, Object) static method when both parameters are non-null.

• A virtual Equals method whose parameter is the record type. This method implements IEquatable.

• An override of Object.GetHashCode().

• Overrides of operators == and !=.

It means that there's not need to enforce the implementation of Equals method in the base abstract record.

If you still want to have custom Equals method implementation and derive from some base record you could do so by declaring virtual Equals method with the derived type as an argument:

I found the solution.

First of all the ConvertTo method should be declared in my project as partial, so I can get ISymbol for the invocation. It gives me the ReturnType

The answer is: yes.

The application service is the one that should care about reading and persisting. The proper use is this:

1. based on some input (ID) you need to get a given domain entity
2. then via the other input parameters you call either a method/property on the entity or you use a domain service where you pass in your domain entities and new inputs.
3. the domain service (or the call on the entity) will do a change in the domain entities. these changes are still in memory.
4. so at the end you will need to persist those changes.

I've just googled a bit, so for more details check out this: https://blog.arkency.com/application-service-ruby-rails-ddd/

I would apply a basic solution if I understood your problem correctly.

If this could be used to calculate the ID-Field it would be a very easy method to have an autogenerator for the ID-Field for every kind of database.

I am afraid not, at any rate, not for "every kind of database". The signifcance of "client-side" is that a client-side method of deriving a row id is no good for a shared database where different users might be attempting to add rows to the same table at the same time.

For a multi-user database, it as always best you use whatever facility the server-side RDMS provides to provide ID-fields values. Some RDMSs like Interbase have so-called generators to do this reliably for you.

You are not passing the collections in the model and UpcommingMeetings causes null exception error in the view;

The main change to facilitate grabbing the id's would be to swap from using execSQL to using insert as insert returns the id of the inserted row, execsql does not.

A little more on this here Using execSQL for INSERT operation in Android SQLite.

However, I'm not sure if you can pass CURRENT_TIMESTAMP via a ContentValues and it would result getting the current timestamp as opposed to just setting the value to the literal CURRENT_TIMESTAMP. You could use DEFAULT CURRENT_TIMEPSTAMP in the respective column definitions (as I have in the code below).

I'd suggest that you would not want a link between every list/product permutation (that would be 100 rows for you 10 List rows and 10 Product rows) as in real life you would probably not have such a scenario rather you'd have some links between the two. So in the code below I've randomly created links.

First some code from the Database Helper (for my convenience named SO45449914) for performing the inserts:-

Well, I've finally solved my own issue. It seems to be a permissions conflict. I've solved using chmod 775 in all project in my CentOS server.
