QUESTION
Hello all!
I recently learned that in newer versions of SQL Server, the query optimizer can "expand" a SQL view and utilize inline performance benefits. This could have some drastic effects going forward on what kinds of database objects I create and why and when I create them, depending upon when this enhanced performance is achieved and when it is not.
For instance, I would not bother creating a parameterized inline table-valued function with a start date parameter and an end date parameter for an extremely large transaction table (where performance matters greatly) when I can just make a view and slap a WHERE statement at the bottom of the calling query, something like
ANSWER
Answered 2021-Jun-14 at 22:08You will not find this information in the documentation, because it is not a single feature per se, it is simply the compiler/optimizer working its way through the query in various phases, using a number of different techniques to get the best execution plan. Sometimes it can safely push through predicates, sometimes it can't.
Note that "expanding the view" is the wrong term here. The view is always expanded into its definition (NOEXPAND excepted). What you are referring to is called predicate pushdown.
I've assumed here that indexed views and
NOEXPANDare not being used.
When you execute a query, the compiler starts by parsing and lexing the query into a basic execution plan. This is a very rough, unoptimized version which pretty much mirrors the query as written.
When there is a view in the query, the compiler will retrieve the view's pre-parsed execution tree and shoves it into the execution plan, again it is a very rough draft.
With derived tables, CTEs, correlated and non-correlated subqueries, as well as inline TVFs, the same thing happens, except that parsing is needed also.
After this point, you can assume that a view may as well have been written as a CTE, it makes no difference.
Can the optimizer push through the view?The compiler has a number of tricks up its sleeve, and predicate pushdown is one of them, as is simplifying views.
The ability of the compiler here is mainly dependent on whether it can deduce that a simplification is permitted, not that it is possible.
For example, this query

ANSWER
Answered 2021-Mar-29 at 03:26From the docs, it looks like res.data.parsed returns an array. You should use res.data.parsed[0].food to get access to the parsed food item and res.data.hints to access the list of foods. I'm guessing you want to display the latter.
QUESTION
I'm attempting to request nutrients from the Edamam Food Nutrition api using Node.JS. They provide this example using curl curl -d @food.json -H "Content-Type: application/json" "https://api.edamam.com/api/food-database/v2/nutrients?app_id=${YOUR_APP_ID}&app_key=${YOUR_APP_KEY}"
I've successively fetched data from their Food Database API where the only parameter is a URL. This one is requires a JSON with the URL. I've hard coded a JSON to correctly call the API. The response I get is
{ "error": "bad_request", "message": "Entity could not be parsed" }
What needs to be changed to get a good response?
...ANSWER
Answered 2021-Mar-16 at 00:50Your data myFood already is a JSON string, then no need to cast it to string with JSON.stringify(data) in postData function.
A simple way to fix this issue - make sure the data object always be a JSON object.
