In MSSQL, you store JSON as nvarchar(max) or some variation of nvarchar, but storage is only half of the JSON story.

In this post, you’ll see how to modify Entity Framework Core to support SQL Server’s JSON_VALUE and JSON_QUERY in
NET Developers also utilize Entity Framework Core to access their database, allowing the library to generate SQL and JSON also lets you be more flexibleĪbout what you store, allowing you to store dynamic data that isn’t easy with relational database schemas. Typically a combination of identifier, sorting columns, and then a JSON column. Information as JSON can help reduce interaction complexity between your application and SQL, with storage objects One of MSSQL’s hidden gems is its ability to allow you to store and query JSON data in existing tables. As a result, there are few surprises when choosing MSSQL, but don’t Option for developers and database administrators. S SQL Server has long been a reliable choice with Microsoft support and a large tooling ecosystem, making it a safe The engine’s popularity is because Microsoft’ NET ecosystem, Microsoft’s SQL Server (MSSQL) andĪzure flavor are still likely the most popular choice for.

The code for this exercise is available on GitHub.While other database providers have made their place known within the. Equipped with these techniques, we can handle almost anything users throw at us and are still able to query data fast enough. Public DbSet WishlistEntries ", "Connected Home & Housewares").ToList() Įven though our application is far from complete we are in a good place. We’ve created a small EF Core project where DBContext looks something like this: class SHDbContext : DbContext From here on we’ll be exploring ways to query the data Test Bench Moving on to coding, let us focus on data retrieval and skip the API part for now – it’s a whole different can or worms and will distract us from our point. We can save heaps of time creating one simple data model and calling it a day. SQL Server has functions to work with JSON data – all we have to do is put it into a sufficiently big column. We could just lump it all together and chuck it into a schema-less data store like Cosmos DB or Mongo, but for the sake of argument we’ll imagine the client was adamant they needed a SQL Server because it’s a business decision they made a long time ago. And, probably, we should not care – perfect data model for frequently changing e-commerce websites would be hard to deduce and likely very painful to maintain.

The catch is, we don’t know full list of attributes. That API will have to make sense of all different attributes each website provides and try store it in a way that makes querying as easy and efficient as possible. We may have a browser extension of some sort that would send information about an item we’re currently watching to an API. Our journey would likely start with a web browser. One realistic case study where this situation may pop up would be building a browser extension that helps capture and organise wish lists from various platforms such as Amazon or eBay. Now we need to bridge the gap and efficiently query it. We have seen a few projects where the client insists on using SQL Server, but their workload generates a bunch of semi-structured JSON data for us to store.
