This kind of error handling does express error state (either via HTTP 500 or by the top-level "errors" key), but it doesn’t take advantage of GraphQL’s type system and can only express one error at a time.

You can use jsonb_agg and jsonb_array_elements_text to flatten or unnest an array of arrays in PostgreSQL: SELECT jsonb_array_elements_text(jsonb_agg(array_of_arrays)) FROM x;

SELECT jsonb_array_elements_text(data->'genres') AS genre FROM books WHERE book_id = 1; That will expand the JSON array into a column:

As stated in the title, I am in a situation where I need to return a count of occurrences within an array, that is within a jsonb column.

json_array_elements_text ( json ) → setof text jsonb_array_elements_text ( jsonb ) → setof text Expands the top-level JSON array into a set of text values. select * from json_array_elements_text('["foo", "bar"]') → value ----------- foo bar

To set multiple cookies in a single set of response headers, you can return an array:

You can freely use destructuring and rest patterns in each blocks.

通常，Arrays用于两种数据结构：queue和stack。 要了解什么queue是食品，您可以想象在食品商店中有一个普通的队列：新人们在队列的末端加入队列，而刚开始的人们则先离开队列。这就是为什么我们需要两种方法来实现的原因queue：一种在的末尾添加元素，Array而另一种在的开始处删除元素的方法queue。这两种方法是push()将一个或多个元素添加到数组的末尾并返回新的数组长度，并shift()删除数组的第零个元素并返回其值：

The slice() method works only with arrays whose elements are strings, numbers, or boolean values.

Indexes can also be negative. If you specify a negative index in the first parameter, it will shift the end of the sequence. For example, slice(-4) call will extract the last four elements of the sequence:

The slice() method does not change the source array, but returns a copy of the array

The current algorithms in the JSON-LD spec do not support the conversion of list of lists to JSON-LD. This is a "Feature at risk" [1].
