To create physical tables, uploading data and creating information views IC_MODELER role is required. If these users are only assigned with IC_PUBLIC role, they can view information views created by other users but can’t create their own views.
In SAP HANA, following engine types are available:Join Engine: This is used for attribute viewsOLAP engine: This is used for analytic viewsCalculation Engine: This is used for calculation views
Assuming a following text file (dict.txt) is present1 aaa2 bbb3 cccFollowing Python code reads the file using open() function. Each line as string is split at space character. First component is used as key and second as valued = {} with open("dict.txt") as f: for line in f: (key, val) = line.split() d[int(key)] = val print (d)The output shows contents of file in dictionary form{1: 'aaa', 2: 'bbb', 3: 'ccc'}
There are four ways of passing objects to functions. Let's assume you have a class X and want to pass it to a function fun, then − Pass by value This creates a shallow local copy of the object in the function scope. Things you modify here won't be reflected in the object passed to it. For example, Declaration void fun(X x); Calling X x; fun(x); Pass by reference This passes a reference to the object to the function. Things you modify here will be reflected in the object passed to it. No copy of the ... Read More
Once data is published to HANA database, you cannot rename the table. In this case, you have to delete the table from Schema in HANA database.
You can use any hashable object like int, string, etc as a key in a python dict. You need to separate it from the value using the ':' delimiter. The value can be any type of object. Consecutive key value pairs must be separated by a comma.
The members and base classes of a struct are public by default, while in class, they default to private. Struct and class are otherwise functionally equivalent.They are however used in different places due to semantics. a struct is more like a data structure that is used to represent data. class, on the other hand, is more of a functionality inclined construct. It mimics the way things are and work.
This mode supports activation of the selected objects only if there are no inconsistent in affected objects in SAP HANA.
Dicts are hash tables. No tree searching is used. Looking up a key is a nearly constant time(Amortized constant) operation, regardless of the size of the dict. It creates the hash of the key, then proceeds to find the location associated with the hashed value. If a collision listed address is encountered, it starts the collision resolution algorithm to find the actual value.This causes dictionaries to take up more space as they are sparse.
This activation mode supports activating the selected objects even if it results in inconsistent affected objects. For example, if you choose to activate an object A that is used by B and C, and it causes inconsistencies in B and C but you can choose to go ahead with the activation of A.
