Row based tables are used when only one record has to be processed at a time. Row based table doesn’t support aggregations and fast searching.When your application needs to access a complete record or a complete row it is recommended to use row based tables.
SAP HANA is an in-memory database so all data resides in memory all the time and hence all calculations and functions can happen directly and hence materialized aggregations are not required in SAP HANA database.With the use of column store, data is available vertically and hence operations on different columns can be easily performed.
The example works correctly. The compareTo() method is called by a string object and takes another string object as argument. The return value is integer and is difference in Unicode values of characters of respective strings when they are not equal. The value can be -ve, 0 or +ve.
To use sockets, consider the WebSocket interface in JavaScript. This interface enables web applications to maintain bidirectional communications with server-side processes. To enable Web applications to maintain bidirectional communications with server-side processes, this specification introduces the WebSocket interface. Here are some of the methods to workaround with Web Sockets − socket = new WebSocket(url [, protocols ] ) Create a new socket using this, wherein parameters URL is a string for the connection and protocols is a string or array of string. socket . send( data ) The above is used to send data. Used to ... Read More
You should do this using a Modify statement as in below − LOOP AT itab. SELECT SINGLE matnr INTO itab-matnr FROM zlldet WHERE palet = itab-palet. MODIFY itab. ENDLOOP. Also note that when you have an internal table itab with a header line, it means that you have a table itab and structure itab and usage of this depends on the situation. Few of the commands like MODIFY and LOOP AT uses both at the same time. DATA itab TYPE TABLE OF [something]. DATA wa ... Read More
Everything in Python is an object, and that includes the numbers. There are no "primitive" types, only built-in types.Numbers, however, are immutable. When you perform an operation with a number, you are creating a new number object.
Here are some of the steps that you can follow to optimize a nested if...elif...else.1. Ensure that the path that'll be taken most is near the top. This ensures that not multiple conditions are needed to be checked on the most executed path.2. Similarly, sort the paths by most use and put the conditions accordingly.3. Use short-circuiting to your advantage. If you have a statement like:if heavyOperation() and lightOperation():Then consider changing it toif lightOperation() and heavyOperation():This will ensure that heavyOperation is not even executed if lightOperation is false. Same can be done with or conditions as well.4. Try flattening the ... Read More

Python cannot iterate over an object that is not 'iterable'. The 'for' loop construct in python calls inbuilt functions within the iterable data-type which allow it to extract elements from the iterable.Since non-iterable data-types don't have these methods, there is no way to extract elements from them. And hence for loops ignore them.
HTML5 applicationCacheIt can be understood by an example that a web application is cached, and accessible without a connected internet. Application cache has some advantages: users can use the application when they're offline, cached resources load faster and reduced server load. Browser cache Web browsers use caching to store HTML web pages by storing a copy of visited pages. After that, the copy is used to render when you visit that page again
