Internal Tables as Data Sources
An internal table can be specified as a
data source data source of a query. This statement cannot be executed on all database systems, if the data from the internal table needs to be passed to the database.
Relational Expressions
The following is now possible for conditions in expressions:
- Size comparisons can now be made between character-like data types and are no longer restricted to numeric data types.
- The operator BETWEEN is also no longer restricted to numeric data types and SQL expressions can now be specified on the right side.
- The operator LIKE is now also supported.
Path Expressions
The following is now possible for path expressions:
- CDS associations can now be used whose association targets are CDS table functions.
- Parameters can now be passed after the CDS associations of a path expression in the specified columns of queries. Until now, this was only possible in path expressions in the data source of the FROM clause of a query. This makes it possible to specify paths whose CDS associations have CDS entities with input parameters as data sources.
- The cardinality and type of the join expression can now be specified as attributes in the square brackets after the CDS associations of a path expression. Until now, only filter conditions were possible.
- Attributes can now be specified after the CDS associations of a
path expression in the
specified columns of
queries. Until now, attributes could only be specified in path expressions in the
data source of the FROM clause of a
query, and only filter conditions were possible.
Access Control
The new addition WITH PRIVILEGED ACCESS disables
CDS access control.
ORDER BY and UP TO, OFFSET in Subquery
In a subquery,
it is now possible to use an ORDER BY
clause and the additions UP TO,
OFFSET can be used after the clause. It is not possible to execute a subquery with an ORDER BY clause on all database systems
Strict Mode in the Syntax Check
If one the new features listed above is used in an statement, the syntax check is performed in a strict mode, which handles the statement more strictly than the regular syntax check.
Client Handling
The following (stricter) rules for the additions USING CLIENT and CLIENT SPECIFIED now apply when switching and disabling implicit client handling in reads on CDS entities:
- CDS access control does not work for client-independent access. For this reason, the additions USING CLIENT and CLIENT SPECIFIED can only be used in in reads on CDS entities for which access control is disabled using the annotation AccessControl.authorizationCheck.#NOT_ALLOWED or the addition WITH PRIVILEGED ACCESS in the FROM clause of an query.
- Path expressions can only be evaluated if implicit client handling is enabled. This cannot be done using CLIENT SPECIFIED in cases where path expressions are used that contain CDS associations whose association target is client-dependent In path expressions in the FROM clause, the association source of the CDS associations cannot be client-dependent either.
