All the operators in the query plan are nested inside subQuery1 that is referenced by DFESubquery. All the operators that are pushed down to the DFE engine have names that start with a DFE prefix. As mentioned
The following code provides an example of a nested loop join. BEGIN; CREATE TABLE public.nestedloop_test_1 ( a integer not null, b integer not null ); CALL set_table_property('public.nestedloop_test_1', 'distribution_key', 'a'); CREATE TABLE public.nestedloop_test_2 ( c integer not...

If you are thinking that output would be a= 10, b= 30 then you are wrong! Consider the statement:int a= 10,20,30;It is a declaration with initialization statement and here comma is a separator and we cannot use values like this. This will be correct output (which is a compile time...
I don't know if this is required? It is documented through kubectl explain --help, should I document somewhere else too? Example: Describe fields and structure of various resources. This command describes the fields associated with each supported API resource. Fields are identified via a simple...
Turnover values, calculated for each pair of cells, range from 0 (functional space of one assemblage is entirely nested within the functional space of another, or functional spaces of both assemblages are identical) to 1 (both assemblages occupy completely different functional spaces). Mean ...
Moreover, maybe with some regular expression, we can do it for arbitrary nested triple terms. We can easily write your idea also in N3: @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix : <http://www.example.org#> . ...
The same concept with code, the else statement is your a.k.a "alternative" , So when your program is executed it checks the condition of your if statement, If it was verified it runs the whole code nested within it! (if the product you wanted was available, you buy it) Else : the...
In factories, for example, it's often necessary to lift things only small distances but move them anywhere on the factory floor. If that's a routine part of the production process, the factory probably has an overhead crane with a trolley-mounted hoist that can travel along bridge-like ...
Using Loops in Programming In most of the programming languages, three looping structures 'for', 'while', and 'do-while' are used to perform the statements that need to be executed repetitively until a given condition is satisfied. For example, the 'for' loop can be implemented (in C) as...
