If you’re getting an error that reads something like “‘DAYS’ is not a recognized dateadd option” in SQL Server, it’s because you’re using the DATEADD() function with an invalid datepart argument.
This often happens when you use a plural form of the argument. For example, DAYS instead of DAY. Or HOURS instead of HOUR.
The easiest way to fix this is to provide a valid datepart argument.
Data fabric is a term that gets used a lot in enterprise tech circles, but it’s often explained in ways that are either too vague or too technical to be useful. Here’s a plain-language breakdown of what it actually means.
High-dimensional vector search is a foundational way AI systems find similar or relevant items across large datasets when the data has been converted into vectors. If you’ve used semantic search, gotten eerily accurate recommendations, or worked with a retrieval-augmented AI tool, this is often the mechanism running underneath.
SQL Server has several functions that return the current date and time. If you just need today’s date for a query, that sounds like it should be simple. And it is. But there are six different functions to choose from, and they don’t all return the same thing. This article explains what each one does and when to use it.
You might have seen “data steward” in a job description or heard it mentioned alongside data governance and wondered what it actually means in practice. It’s one of those roles that’s easy to overlook but plays a surprisingly important part in keeping an organization’s data trustworthy and usable.
Semantic retrieval is a way of finding information based on meaning rather than matching exact words. You ask a question or describe what you need, and the system finds relevant results even if they use completely different wording. That gap between what someone types and what they actually mean is exactly what semantic retrieval is designed to close.
If you’re getting error 9810 that reads something like “The datepart hour is not supported by date function dateadd for data type date“, it’s because the datepart that you’re trying to add or subtract a datepart is not supported for the data type of the original value.
This typically happens when you try to add a timepart to a date value. For example, trying to add an hour to a date value will result in this error, because the date type doesn’t support the hour datepart. You can’t have a date value that includes the hour.
One of the hardest things about building AI systems is that the things humans care about (words, sentences, images, ideas, etc) aren’t naturally something a computer can do math on. A computer doesn’t inherently know that “happy” and “joyful” are similar, or that a photo of a dog and the word “dog” are related. It just sees raw data.
Embeddings are the solution to that problem.
Bad data is more common than most organizations want to admit. And more costly. Decisions get made on outdated numbers, reports contradict each other, and engineers spend hours tracking down why a dashboard looks wrong. Data quality management is how you prevent all of that from becoming the norm.
Dates in SQL Server can be surprisingly tricky if you’re new to the game. The way dates are stored is not always the way you want them displayed, and figuring out how to convert one to the other is one of those things every beginner eventually Googles. So let’s walk through it clearly.
