In concrete terms, an ABAP-Managed Database Procedure is written in a database-specific language, such as Native SQL or SQL Script, and is implemented within an AMDP method body of an AMDP class.
Advertisements. A procedure allows you to group the SQL statement into a single block. Stored Procedures are used to achieve certain result across applications. The set of SQL statements and the logic that is used to perform some specific task are stored in SQL Stored Procedures.
A function is a rule that assigns a set of inputs to a set of outputs in such a way that each input has a unique output. A function table in math is a table that describes a function by displaying inputs and corresponding outputs in tabular form.
Most RDBMS database uses SQL as database language, the reason of being popular is – it is powerful, vendor independent and standardized. SAP HANA also supports SQL. In SAP HANA, SQL is the main database language.
SQL Script is known as collections of SQL extensions. These extension are Data Extensions, Function Extensions, and Procedure Extension. SQL Script supports stored Functions and Procedures and that allows pushing complex parts of Application logic to database.
Procedure
- Open a New Scalar Function or New Table Function wizard. Go to the Project Explorer view in the SAP HANA Development perspective, right-click on the file name, choose New Other SAP HANA Database Development Scalar Function.
- Define the function parameters.
- Commit and activate your function.
A view is an entity that is not persistent; it is defined as the projection of other entities. SAP HANA Extended Application Services (SAP HANA XS) enables you to create a CDS view as a design-time file in the repository. Repository files can be read by applications that you develop.
ABAP CDS table functions define table functions that are implemented natively on the database and can be called in CDS. A CDS table function is defined using the ABAP CDS statement DEFINE TABLE FUNCTION and can be used as the data source in Open SQL read statements.
User-defined table types are the predefined tables that the schema definition is created by the users and helps to store temporary data. User-defined table types support primary keys, unique constraints and default values, etc.
The word table is derived from Old English tabele, derived from the Latin word tabula ("a board, plank, flat top piece"), which replaced OE bord; its current spelling reflects the influence of the French table.
End Tables and Accent Tables: Smaller and with less surface area than coffee tables and console tables, end tables and accent tables are usually used at the end of a bigger piece of furniture.
- In the initial screen of the ABAP Dictionary, enter the table type name in field Data type and choose Create.
- Select Table type and choose Choose.
- Enter an explanatory short text in the field Short text.
- Enter the row type of the table type on the Row type tab page.
Parts of a Table
- Title number and title.
- Divider rules.
- Spanner heads.
- Stub heads.
- Column heads.
- Row titles.
- Cells.
- Footnotes.
A console table is wide, fairly shallow and roughly as tall as a regular table or desk. A console table is often placed against a wall – but when it's placed against the back of a sofa, it's called a sofa table.
Tabulation refers to the system of processing data or information by arranging it into a table. With tabulation, numeric data is arrayed logically and systematically into columns and rows, to aid in their statistical analysis.
Types of SAP Tables- cluster table, transparent table, Pooled Tables
- Cluster table.
- Transparent table.
- Pooled table.
There are 4 Table-Types within the SAP System:
- Tables which have technical control functions within the SAP system.
- Other tables contain basic commercial data (bank data, currency ).
- Tables for the organization of a company (company codes, customer data ).
Variables are assigned to Attributes of the Analytical and Calculation views at design time to filter data based on the values you provide for the variable at run time. Values are provided to the variables either by entering them manually or by selecting them from the value help dialog.
To declare a variable, you use the DECLARE statement. For example, the following statement declares a variable named @model_year : DECLARE @model_year SMALLINT; The DECLARE statement initializes a variable by assigning it a name and a data type.
SAP HANA, express edition is available for free, for development and productive use, up to 32GB of RAM. SAP HANA combines an ACID-compliant, in-memory database with advanced analytics processing, such as geospatial, graph, document store and machine learning libraries.
The Systems, Applications & Products implementation which is popularly known as SAP is an application that is designed to run an SAP HANA database. SAP HANA, on the other hand, is an in-memory database.
1 Introduction. SAP HANA provides client interfaces for connecting applications as part of the SAP HANA client software package. The SAP HANA client can be installed on both Unix/Linux and Microsoft Windows operating systems, as well as on an SAP HANA server host during server installation.
SAP HANA Capabilities
- Database Services. Simplify your IT landscape and reduce data management burdens with a unique and enterprise-proven database platform.
- Multi-Model Processing with Advanced Analytics.
- Application Development.
- Data Virtualisation.
There're quite a few differences but a stark difference is that HANA studio is a (thick) client that need to be installed on end user/administrator computer whereas HANA Cockpit is a server level product with its own database being HANA express edition.
Start SAP HANA Studio in a Terminal
- Open a Terminal and navigate to the following directory: /Applications/sap/
- Start the SAP HANA studio application: open -a hdbstudio.app Note. If you start the SAP HANA studio in a terminal you can add command line options (for example to set the SAP HANA studio workspace or to start an immediate system logon).
How SAP HANA Gets Its Speed. SAP HANA offers improved productivity because of its architecture. Second, SAP HANA typically stores data in column-based tables versus the traditional row-based tables of an RDBMS. This columnar structure provides faster access because most queries only address certain sets of columns.
SAP HANA 2.0 Studio Installation and Update. Most of you will be intimately familiar with the SAP HANA studio, the central development environment and the main administration tool for SAP HANA 1.0.
The main SAP HANA database management component is known as the index server, which contains the actual data stores and the engines for processing the data. The index server processes incoming SQL or MDX statements in the context of authenticated sessions and transactions.
