SAP delivers annotation definitions for the SAP annotations. No other annotations should be used at present.
Cardinality in LEFT OUTER JOIN
In a LEFT OUTER JOIN,
an addition TO ONE or TO MANY can be specified for the cardinality. This addition is evaluated by an
SAP HANA database as a note for optimization.
This option exists in earlier releases in ABAP CDS, but has been documented only from Release 7.52. In
Open SQL, the corresponding syntax was introduced in Release 7.52.
The following enhancements have been implemented in CDS access control:
CDS roles can now also be defined for
CDS table functions. When a CDS table function is accessed in Open SQL. The access conditions are evaluated by default.
Extensions in DCL for defining CDS roles:
When access conditionscond_expr are
specified, there are no longer any restrictions on how Boolean operators and parentheses are used. The
Boolean operator NOT can now also be used and any combination of parentheses is possible.
When a path is specified for an element in an access condition, multi-value associations are now also tracked.
Further conditions can now be appended after INHERIT using AND.
In a literal condition[NOT] LIKE, it is now possible to specify an escape character using ESCAPE.
Blanks are now no longer forced in certain positions.
