I have created a Database Project in VS 2012.
Currently when I use the import option I do not see any means to filter out the schemas that I don't want. I can either import the whole DB or nothing at all.
However, I need to import only those database objects that belong to a particular schema (e.g. import only the objects in Schema 'User')
Is this even possible? If yes, how?
Thanks,
Rashmi

I am creating a dataset of Azure blob storage type. While watching youtube videos of ADF i saw sometimes we import schema and sometimes we not
can you please guide me when we have to click on import schema
Just to add to what Chen said .
If you know that the your only focus is some few columns from source and there is a chance that your source can have few new columns in future , please go with mapping option . This saves from the any changes made on the source side .
If you want to make the pipeline more generic , please plan for going without mapping .
If you import schema you can easily map columns in the mapping tab of copy activity. If you don't import schema, your dataset can be generic, and you can use it with different tables, without the need to create a dataset for each table.
Let's say I have a backend that needs to be able to receive big JSON files containing data.
This JSON data should be decomposed into several different tables/entities (in order to be easily manipulated by a frontend).
Those different entities should be in relation to each other (one-to-many/many-to-one relations).
In your opinion, what's the best way populate a db from a JSON file, using nest js and typeORM ?
Thanks in advance for your knowledge,

you mean fast define entities from a json file.
If right, I usually use app https://app.quicktype.io/ to convert json file to interface type (select language Typescript and interface only)
Then use editor replace interface to class
replace with expression ;\n to ;\n\n\t#Column()\n
replace with expression export class to #Entity()\n export class
then import decorator Column, Entity, add option to column as you need
I am using Kentico v10.0, I have 400+ records that needed to be enter.
Currently the data was stored using custom table. Is that a way for me to import all the data from an excel file? I think no one likes to do data entry jobs...
So by using the Kentico Import Toolkit is able to achieve what I request.
But I found another problems which there are many empty fields like the picture below:
I have no idea what to put as the default value while importing, so i decided to leave it empty.
Will it affect anythings in the future if these fields are NULL?
Or there is a way to set the default value from the kentico itself? So I don't need to bother the default value while importing.
Use the Kentico Import Toolkit. You can import into your site directly from the Excel sheet. You can also use SQL Server Management Studio to import the custom table data. I'd not recommend using SSMS for anything other than custom table data though.
I would suggest in this order.
Kentico import Toolkit. Very versatile and can be used for other things too. You don't have to worry about those null values unless those values are supposed to be mandatory non-null values.
Second option would be to connect to Kentico's DB using SSMS and import the data in the desired table.
I want to have default values for certain fields in my mongoose models. The trick is I don't want to store these values in the database, but what to add them when the model is initialized.
Please help.
You can define an 'init' middleware function for the schema which runs when a model instance is loaded from the database. That should let you manipulate the instance to add your defaults as needed.
Also see this related question for more details as the docs are pretty spare on this.
Maybe a json file?
Using a require('path/to/json' ) you can acces to it and get the values.
Im actually doing something like that, but using the same JSON SCHEMA wich is build for validation purpose.
I have some quite big model, described in a number of xsd schemas. Schemas are referencing each other by includes. For example, A schema contains a 'someEnum' enumeration. B schema want to use that enum, so it include's the A schema. The problem is, when i import my XSD to eCore model's EMF are not only generates such an enum twice, but it aslo generates all the elements in B schema in model for A schema. I'm feeling that i'm doing something wrong, but can't figure out what exactly. Any help are very appreciated!
If you did select one xsd at a time in the EMF Project Wizard, then you should start with the xsd, that doesn't depend on anything. After the import of the first xsd finished, the EMF Project Explorer offers you to select referenced models during the import of the next xsd. Then you have to select the appropriate ones.
You are also able to import multiple xsds at once with the EMF Project Wizard. Then the references should be set correctly, if the namespaces of the xsds refer to each other.
