As an SQL developer, you have to perform various tasks, such as writing SQL queries, optimizing database performance, and ensuring data integrity. SQL developers are also responsible for designing and maintaining databases. Not only this, you have to collaborate with various teams, such as data ...
Why We Have to Join 3 Tables in SQL Let's take a second to talk about database design. The reason it's common now to have to make joins across more than two tables is because database normalization is now common. Databases (and really the people who design databases) do this by orga...
This method uses LINQ to perform the necessary calculations and ordering, similar to your SQL query. The FullOuterJoin method is a custom extension method to perform a full outer join in LINQ, which you can implement as follows:C# Copy ...

There are a few rules for database normalization. Each rule is called a “normal form.” If the first rule is observed, the database is said to be in “first normal form.” If the first three rules are observed, the database is considered to be in “third normal form.” The third...
If your response time is not as critical, you can also use an additional LLM to perform a review of the response before it is returned to the user, looking for issues. We will review how to add a second LLM call in code lab 5.3, but with a focus on preventing prompt attacks. But ...
