A new version of Metastorage was
released to introduce several enhancements to the capabilities of report
classes and to the Object Query Language. A few bugs were also fixed in
this release.
- Report row grouping
This release of Metastorage introduces the possibility to group
rows of report query results, similar to using SQL GROUP BY
clause.
Report column values can now use these functions to compute group row
summary values: count, minimum, maximum,
average and sum.
- Date and time OQL constant expressions
The Object Query Language (OQL) was enhanced to support constant
expressions relative to the current date and time of when the queries
are executed. These expressions can be used to avoid having to pass
arguments with date and time values to the functions that execute the
queries.
Currently supported date and time expressions include UTC and local time
zone variants of the current timestamp, date, time, and day of the week.
- Other bug fixes
This release also includes several fixes. The algorithm that computes the
path of parsed XML cache files was changed to avoid generating long path
names. The previous algorithm generated paths that could exceed the limits
of Windows file systems. The reports can now have columns defined by
boolean type expressions.
