Rick Hillegas updated DERBY-5554:
---------------------------------
Attachment: derby-5554-02-aa-0argConstructor.diff
Attaching derby-5554-02-aa-0argConstructor.diff. This patch adds a 0-arg
constructor to SPACE_TABLE. I am running regression tests now.
The meaning of the 0-arg constructor is "give me information on all
conglomerates for all tables". With this patch, the following statement returns
space information on all conglomerates:
select * from table(syscs_diag.space_table()) x
order by conglomeratename;
This patch allows us to re-write the example in the Reference Guide section on
SPACE_TABLE. The following new syntax is valid standard SQL:
select t2.*
from
sys.systables systabs,
table (syscs_diag.space_table()) as t2
where systabs.tabletype = 'T'
and systabs.tableid = t2.tableid;
Bryan's query can now be re-written as follows. Note that the join to
SYSCONGLOMERATES gives rise to a cartesian product because there is no unique
join column between SYSCONGLOMERATES and SPACE_TABLE. This was true of the
original query also:
select t2.*, systabs.*, syscgs.conglomeratenumber
from
sys.systables systabs, sys.sysconglomerates syscgs,
table (syscs_diag.space_table()) as t2
where systabs.tabletype = 'T'
and systabs.tableid = t2.tableid
and systabs.tableid = syscgs.tableid;
Touches the following files:
----------
M java/engine/org/apache/derby/impl/sql/catalog/DataDictionaryImpl.java
M java/engine/org/apache/derby/iapi/sql/dictionary/DataDictionary.java
Expands the meaning of getConglomerateDescriptors( UUID ). If the UUID argument
is null, this method now returns all of the conglomerates in the database.
----------
M java/engine/org/apache/derby/diag/SpaceTable.java
Gives SPACE_TABLE a 0-arg construtor which behaves as described above.
----------
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/SysDiagVTIMappingTest.java
Tests for the new constructor.
