HANA XS SPS 10: HANA XS Admin Tool: Translation
New tool specifically design for
performing online translations
URL: /sap/hana/xs/translationTool/
Role:
sap.hana.xs.translationTool.roles::translator

HANA XS SPS 10: HANA XS Admin Tool: SQLCC Auto User
New parameter for SQLCC:
role_for_auto_user
Allows for the generation of an automatic
user and the specification of a single role
you wish to assign to that user
You can now transport a DU with SQLCC
and it is ready to use without any user
creation or administrative setup

HANA XS SPS 10: HANA XS Admin Tool: Self Service Improvements
User Self Service e-mail templates can now
be customized

HANA XS SPS 10: HDBSYNONYM
New development artifact for SPS 10 to
allow for the design time definition of
Synonyms upon catalog tables
• Especially useful for access to ERP and
other ABAP created tables
{ "acme.com.app1::MySynonym1" :
{ "target" :
{ "schema": "DEFAULT_SCHEMA",
"object": "MY_ERP_TABLE_1" },
"schema": "SCHEMA_2" } }

HANA XS SPS 10: Core Data Services
Mission Statement
 CDS provides an enriched data model
 CDS allows for graceful life-cycle management
 CDS allows for extending the meta-model
Features coming with SPS 10
 Extend HANA SQL Function Support
 GIS Types and Functions
 Global temporary column tables
 Foreign keys of managed associations in definition of other associations
 Filter Conditions and prefix notation
 Series Entities
 Code Completion in the Web-based Development Workbench

HANA XS SPS 10: CDS - Extend HANA SQL Function Support
CDS now supports almost all HANA SQL functions
The following functions are not supported:
• The functions in the section Fulltext Functions
• The functions in the section Window Functions
• the functions GROUPING, GROUPING_ID, MAP in the section Miscellaneous
Functions

HANA XS SPS 10: CDS - GIS Types and Functions
Definition of entities with GIS element
types in SPS 09
SPS 10 adds GIS functions define view BPAddrExt as select from
MD.BusinessPartner {
PARTNERID,
ADDRESSES.STREET || ', ' ||
ADDRESSES.CITY as FULLADDRESS,
round( ADDRESSES.POINT.ST_DISTANCE(NEW
ST_POINT(8.644072, 49.292910), 'meter')/1000,
1) as distFromWDF03
};

HANA XS SPS 10: CDS - Global temporary column tables
Added support for global
temporary column tables
• Temporary global column
tables must not have a key nor
an index.
• Note that a temporary
entity/table cannot be changed
when the table is in use by an
open session
@Catalog.tableType : #TEMPORARY_GLOBAL_COLUMN
entity ProductTemp {
PRODUCTID: String(10);
DATETIME: UTCDateTime;
USERNAME: String(20);
};

HANA XS SPS 10: CDS - Foreign keys of managed associations in
Up to SPS 09, the appearance of
“circular” associations caused an
error.
Now, the compiler recognizes that
the referenced field is actually
part of the base entity and thus
can be obtained without following
the association in such
relationships
entity Header {
key id : Integer;
toItems : Association[*] to Item on
toItems.head.id = id;
};
entity Item {
key id : Integer;
head : Association[1] to Header { id };
};

HANA XS SPS 10: CDS - Filter Conditions and prefix notation
When following an association, it
is now possible to apply a filter
condition, which is mixed into the
ON-condition of the resulting
JOIN
view BPOrdersView as select from BusinessPartner {
PARTNERID,
orders[LIFECYCLESTATUS='N'].SALESORDERID as orderId
};

Associations
with filters are never combined.
In order to tell the compiler that
there actually is only one
association, you have to use the
prefix notation
view BPOrders2View as select from BusinessPartner {
PARTNERID,
orders[LIFECYCLESTATUS='N'].{ SALESORDERID as orderId,
GROSSAMOUNT as grossAmt }
};

Prefixes can be nested:
view BPOrders3View as select from BusinessPartner {
PARTNERID,
orders[LIFECYCLESTATUS='N'].{ SALESORDERID as orderId,
GROSSAMOUNT as grossAmt,
ITEMS[NETAMOUNT>200].{ PRODUCT.PRODUCTID,
NETAMOUNT }
}
};

HANA XS SPS 10: CDS - Series
CDS syntax now supports the
HANA Series keyword
entity MySeriesEntity {
key setId : Integer;
key t : UTCTimestamp;
value : Decimal(10,4);
series (
series key (setId)
period for series (t)
equidistant increment by interval 0.1 second
)
};
