When creating a Synonym, the user needs to follow the bellow steps:ġ.Identify /create a user (granting user) which as the necessary privileges for the external object and has the ability to grant these privileges (Grant option)Ĭommands to create a user with respective privileges:Ĭommands to create role with respective privileges:Ģ.Create a user- provided service that accesses the remote database and schema via the driver named .jdbc.Driverģ.Create a. Used to re-point functions and stored procedures to various external objects (tables, views or sequences) without the need to rewrite the function nor the procedure. SAP HANA SQL Reference Guide for SAP HANA: Create Library Statement Libraries are limited to SQLScript procedures or functions and are not available in other SQL statements. A user may create libraries and utilize them in other procedures or functions. SAP HANA SQL Reference Guide for SAP HANA: Structured PrivilegeĪ collection of functions and procedures within a defined library written in SQLScript. A view may occasionally contain additional security checks such as STRUCTURED PRIVILEGE CHECK which is used to provide fine-grained control over which data a user can see within a view. SAP HANA SQL Reference Guide for SAP HANA: Create Table StatementĪ virtual table based on the dynamic results returned in response to an SQL statement. Primary Key: a column or a set of columns in a table whose values uniquely identify a row in the table.Īssociations: Define relationships between tables. A database table is typically a two-dimensional data structure with cells organized in rows and columns usually with a Primary Key and sometimes an association. SAP HANA is optimized for column storage. The SAP HANA database supports two types of tables being columnar and row-based data storage. SAP HANA SQL Reference Guide for SAP HANA: Create Function Statement Depending on the returned interface in SAP HANA we distinguish between a Scalar and Table UDF.

Ideally, SQLscript is the language used in SAP HANA to write the below mentioned using a combination of declarative and imperative orchestration logic: Which otherwise in a traditional three-tier architecture the application layer would assume the responsibility of executing the business logic but this approach fails to leverage fast column operations, query optimization and massive parallel processing capabilities of SAP HANA with multicore CPUs and all the data residing in-memory (Brandeis 2021) The objective for SQLscript is to exploit specific features of SAP HANA, allowing much more pushdown of the data intensive processing to the SAP HANA Database layer. The DB artifacts are represented in an SQLscript which serves as an extension of ANSI SQL being the lingua franca of the database. The described aims to enlighten the audience on the various components, frameworks and strategic mechanisms that make up the SAP HANA Database artifacts.
