To find T-SQL topics, use search at the top right of this page, or use the table of contents on the left side of the page. To find the system tables, views, functions, and procedures, see these links, which are in the Using relational databases section of the SQL documentation. Near the top of each topic is a section that indicates which products and services support subject of the topic.
Another example, the following label indicates a topic that applies only to Azure Synapse Analytics and Parallel Data Warehouse. In some cases, the topic is used by a product or service, but all of the arguments are not supported. In this case, other Applies to sections are inserted into the appropriate argument descriptions in the body of the topic.

That said, I don't mean proprietary extensions are evil, just that the options should be considered. Lott Adrian doesn't need a reason to ask the question. And any explanation he gives is irrelevant, as there can be others who have the same need for a different reason.

ISO has a list of freely available standards. This should be the first part of series of standards, which are not so publicly available.
Its in PDF format, so it should be a better read the older? The standard seems to be missing from the list. The standard is there. That, in turn, has been superseded by the standard, which now has json support. I haven't found a free version of anywhere. Oops -- the document isn't useful. It's only part 1, and part 2 is the one that contains actual sql syntax. Add a comment. Isn't C exactly like SQL in this way, with lots of different competing extensions before the standardization effort?
Which produced C89, so it may look now like everyone always followed the standard, 20 years later. Lott S. Lott k 75 75 gold badges silver badges bronze badges. Question was about an SQL Reference. The answer therefore has to be ANSI. And they're dirt cheap too Aaron Digulla Aaron Digulla k gold badges silver badges bronze badges. And yeah ansi sql don't solve everyday problems but so does every sql dialect, meaning you need the procedural part and so on.
None of them are very alike even when you just look at the Q query part. Oracle supports recursive queries and optimizer hints, for example. I'm not sure which parts of which standard SQL Lite implements but it's a moot point. If you limit your studies to ANSI, then you will stumble over a lot of extra details when you try to apply it the first time.
I, for example, haven't felt a need to look into the standard since I left college 20 years ago. Community Bot 1 1 1 silver badge. Yada Yada Yes it's a good book about relation database concepts and theory, but it's not an SQL language reference. Good one. I agree Celko's books are worth reading, but they are not complete SQL reference books.
