If SQL query performance is poor or query results do not meet expectations, you can execute the EXPLAIN and EXPLAIN ANALYZE statements in Hologres to obtain execution plans of query statements. This way, you can
EXPLAIN command returns the execution plan of parsing engine in English. It can be used with any SQL statement except on another EXPLAIN command. When a query is preceded with EXPLAIN command, the execution plan of the Parsing Engine is returned to the user instead of AMPs....
The use of high-level instructions during the design process is an example of abstraction. a) True. b) False. Most Boolean functions on N inputs have an exponentially long (as a function of N) minimal description (in any fixed reasonable encoding /...
Answer and Explanation: Particularly, the statement presented best illustrates the"explain"(c) goal of psychology. This is due to the statement is giving the...
I'd also expect optimizer to NOT allow functions in cases like that if they do NOT have DETERMINISTIC property. And if function is created as DETERMINISTIC, it should NOT contain any INSERT/UPDATE/DELETE statements. These will prevent the problem to some extent....
False rumors (often termed “fake news”) on social media pose a significant threat to modern societies. However, potential reasons for the widespread diffusion of false rumors have been underexplored. In this work, we analyze whether sentiment words, as
To develop software, the object-oriented concepts need to be implemented in any high-level language. The high-level language that implements the concepts of object-oriented programming is known as an object-oriented language (also called an OO language). In general, an object-oriented language mu...
3D modeling heavily uses vector algebra. Of course pure SQL offers enough math functions to get around. But functions and routines are not first class citizens in SQL, which means we would have to copy-paste the bulky vector manipulation formulas every time we will need them, which would make...
and therefore resembled a bisyllabic speech item (see Fig.2a,b). Moreover we applied fade in and out functions for the first and the last 100 ms so as to remove any on-and offset artifacts. The average duration of action sounds was\(\mathrm {m}= 934 \pm 473.19\,{\hbox {ms}}\)...
For each behavioural state and study period, we built a list of candidate models from the above predictors, ranging from the simplest models including only one predictor to complex models including all predictors (10, 8, 8 and 6 models were tested respectively for the fox active state during ...
