In C and C++, string literals next to each other are concatenated. As these languages influenced Ruby, I’d guess it inherits from there. And it is documented in Ruby now: see this answer and this page in the Ruby repo which states: Adjacent string literals are automatically concatenated by the interpreter: “con” “cat” “en” “at” … Read more
As usual, the itertools module contains a solution: >>> l1=[1, 2, 3] >>> l2=[4, 5, 6] >>> l3=[7, 8, 9] >>> import itertools >>> list(itertools.chain(l1, l2, l3)) [1, 2, 3, 4, 5, 6, 7, 8, 9]
Use Variable Interpolation: @url: “@{root}@{file}”; Full code: @root: “../img/”; @file: “test.css”; @url: “@{root}@{file}”; .px{ background-image: url(@url); }
The structure std::vec::Vec has method append(): fn append(&mut self, other: &mut Vec<T>) Moves all the elements of other into Self, leaving other empty. From your example, the following code will concatenate two vectors by mutating a and b: fn main() { let mut a = vec![1, 2, 3]; let mut b = vec![4, 5, 6]; … Read more
Yes: list1 + list2. This gives a new list that is the concatenation of list1 and list2.
You could write it this way: SELECT Distinct tbl.Chain, tbl.Store, ConcatRelated(“Warehouse”,”tbl”,”Chain=””” & [Chain] & “”” and Store=””” & [Store] & “”””) AS Warehouses FROM tbl;
You can put all word arrays into one array and use a recursive function like this: function concat(array $array) { $current = array_shift($array); if(count($array) > 0) { $results = array(); $temp = concat($array); foreach($current as $word) { foreach($temp as $value) { $results[] = $word . ‘ ‘ . $value; } } return $results; } else … Read more
I used a subquery for the GROUP BY which computes the Sum of Err for each group. Then I added the ConcatRelated function (from Allen Browne) with the fields returned by the subquery. This is the query and the output (based on your sample data in make_table_bp) from the query: SELECT sub.[Name], sub.Cat, sub.[Desc], sub.Thresh, … Read more
I previously said that this couldn’t be done, but I was wrong. I ended up needing something like this myself so I looked around, and discovered that server-side prepared statements let you build and execute arbitrary SQL statements from strings. Here is an example I just did to prove the concept: set @query := ( … Read more
With MSSQL you can do something like this: declare @result varchar(500) set @result=”” select @result = @result + ModuleValue + ‘, ‘ from TableX where ModuleId = @ModuleId
