Spring Data JPA And NamedEntityGraphs
We ran into a similar problem and devised several prospective solutions but there doesn’t seem to be an elegant solution for what seems to be a common problem. 1) Prefixes. Data jpa affords several prefixes (find, get, …) for a method name. One possibility is to use different prefixes with different named graphs. This is … Read more
GET with query string with Fetch in React Native
Your first thought was right: just add them to the URL. Remember you can use template strings (backticks) to simplify putting variables into the query. const data = {foo:1, bar:2}; fetch(`https://api.parse.com/1/users?foo=${encodeURIComponent(data.foo)}&bar=${encodeURIComponent(data.bar)}`, { method: “GET”, headers: headers, })
Using Axios GET with Authorization Header in React-Native App
For anyone else that comes across this post and might find it useful… There is actually nothing wrong with my code. I made the mistake of requesting client_credentials type access code instead of password access code (#facepalms). FYI I am using urlencoded post hence the use of querystring.. So for those that may be looking … Read more
PDO::fetchAll vs. PDO::fetch in a loop
Little benchmark with 200k random records. As expected, the fetchAll method is faster but require more memory. Result : fetchAll : 0.35965991020203s, 100249408b fetch : 0.39197015762329s, 440b The benchmark code used : <?php // First benchmark : speed $dbh = new PDO(‘mysql:dbname=testage;dbhost=localhost’, ‘root’, ”); $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $sql=”SELECT * FROM test_table WHERE 1″; $stmt = $dbh->query($sql); … Read more
Next.js: Reduce data fetching and share data between pages
O’right! I found this thread while I was looking for something else. But since I had to work on similar issues, I can give you some directions, and I will do my best to make it clear for you. So there are some data which you want to have it share, across your app (pages/components). … Read more
redirect after a fetch post call
Request.redirect could be “follow”, “error” or “manual”. If it is “follow”, fetch() API follows the redirect response (HTTP status code = 301,302,303,307,308). If it is “error”, fetch() API treats the redirect response as an error. If it is “manual”, fetch() API doesn’t follow the redirect and returns an opaque-redirect filtered response which wraps the redirect … Read more
Fetch vs FetchMany in NHibernate Linq provider
Fetch should be used for references and FetchMany for collections. This is particularly important because only FetchMany can be combined with ThenFetchMany to fetch “grandchildren” collections. Example: session.Query<User>() .FetchMany(u => u.Orders) .ThenFetchMany(o => o.OrderItems)
query specified join fetching, but the owner of the fetched association was not present in the select list
Use regular join instead of join fetch (by the way, it’s inner by default): String hql = ” select ec.id as entityChangeId, r.id as revisionId from EntityChange as ec ” + ” join ec.revision as r ” + … As error message tells you, join fetch doesn’t make sense here, because it’s a performance hint … Read more
What is the difference between JOIN and JOIN FETCH when using JPA and Hibernate
In this two queries, you are using JOIN to query all employees that have at least one department associated. But, the difference is: in the first query you are returning only the Employes for the Hibernate. In the second query, you are returning the Employes and all Departments associated. So, if you use the second … Read more
