Query To Trace All Parents
Jul 23, 2005
Hi,
I have a table with filled out below data:
+------+-----+
|parent|child|
+------+-----+
|A |B |
|B |C |
|B |E |
|C |D |
|E |F |
|E |G |
+------+-----+
So I have to make a query which get all 'parent' values values for
given child value.
For example :
-----------------
If I have to get all parent values for 'D' child., query must get this
values : C, B, A.
If I have to get all parent values for 'F' child., query must get this
values : E, B, A.
If I have to get all parent values for 'C' child., query must get this
values : B, A.
If I have to get all parent values for 'B' child., query must get this
values : A only.
-----------------
Is it possible to create a query which will covers all above conditions
or not using only sql statement without UDF or stored procedures.
Any solutiuons?
Sincerely,
Rustam Bogubaev

Hi all,
I would like to track the queries submitted to a SQL SERVER 2005 database in my university.
I would like to create a metadata repository that will collect what was the query, who executed it and when.
Can you think of a way to do it?
thanks,
Yoav

Hi,
When looking in the server trace in query analyzer – I can see how many ‘reads’ a stored procedure does.
So I'm wondering if we can determine whether our query is good or bad by looking at the number of reads/writes that showing in the Trace.
Thanks in advance

Hi,
I am trying to figure out if this is possible in Oracle or Mysql
Lets say I have 3 tables such that C could have either A or B as its parent.
A
{ id, name}
B
{id, name}
C
{other_id, comment}
Now other_id could be either A.id or B.id. What I want to be able to do is to define a foreign key constraint of the type:
CONSTRAINT FK_C FOREIGN KEY (other_id) REFERENCES A(id) ON DELETE CASCADE,
CONSTRAINT FK_C FOREIGN KEY (other_id) REFERENCES B(id) ON DELETE CASCADE
such that deleting A.id automatically deletes C.other_id where A.id = C.otherid and same for B.id
Ofcourse i am not able to do this. Is there any way that this can be done in Oracle and Mysql?
Thanks a lot,
Priyanka

We have stored some special characters in our database and when we extract as XML Auto, Elements it through error illegal characters during import. I am looking and saw CDATA with Explicit option but don't know how to use it with multi tags like:
<1>
<12>
<23>
<34>
</34>
</23>
</12>

I have a user assigned multiple roles and a role can be inherited frommultiple parents (see below). How do I answer such questions as "Howmany roles does the user belongs to?"I answered the above questions by using .NET but I think it can bemore efficient by using just SQL. I would appreciate if you can giveme an answer.Thank you.CREATE TABLE [dbo].[tb_User] ([Id] [int] IDENTITY (1, 1) NOT NULL PRIMARY KEY,[Name] nvarchar(99) NOT NULL UNIQUE,[Password] nvarchar(99) NOT NULL,) ON [PRIMARY]GOCREATE TABLE [dbo].[tb_Role] ([Id] [int] IDENTITY (1, 1) NOT NULL PRIMARY KEY,[Name] nvarchar(99) NOT NULL UNIQUE,) ON [PRIMARY]GOCREATE TABLE [dbo].[tb_User_Role] ([UserId] [int] NOT NULL ,[RoleId] [int] NOT NULL,) ON [PRIMARY]GOALTER TABLE [dbo].[tb_User_Role] WITH NOCHECK ADDCONSTRAINT [PK_tb_User_Role] PRIMARY KEY CLUSTERED([UserId],[RoleId]) ON [PRIMARY]GOCREATE TABLE [dbo].[tb_Parent_Role] ([RoleId] [int] NOT NULL ,[ParentRoleId] [int] NOT NULL ,) ON [PRIMARY]GOALTER TABLE [dbo].[tb_Parent_Role] WITH NOCHECK ADDCONSTRAINT [PK_tb_Parent_Role] PRIMARY KEY CLUSTERED([RoleId],[ParentRoleId]) ON [PRIMARY]GO

Hi!
How can I make a relation that would let me relate an employee to two departments?
There is a table with emloyees and each one works in a department and there is a foreign key relation in the child (employees) table to the parent (departments) table. So can an employee work in two departments? (it's not impossible to imagine, is it?) And how would I retrieve all the employees of a department?
Or in other words, if I were working on some kind of software for my local supermarket and they need to keep track of all bills they ever gave out. I would make this products table and this bills table. Then I would create a foreign key column in the products table and fill it with bill_ids from the bills table and make retrieving bill items a simple getchildrow[](bill_row). Note that this is only an analogy, I need it done this way. How? (using C# express 2005, and SQL express and DataSets)

Hi,I have a tree structure which is maintained through the use of a pathenumerated column:CREATE TABLE items (item_id NUMERIC NOT NULL,path VARCHAR2(64) NOT NULL);The path is is a colon separated list of ids of the nodes of the tree.So, for example, in this structure:0 -> 1 -> 2 -> 3 -> 4item id 4 would have a path of '0:1:2:3' (0 is the root of allitems, and does not actually exist). Notice that the path does notinclude the item's own id.I would like to select all of the items in a given item's path:SELECT id, path FROM items WHERE id IN (PATH_TO_IDS(path));or maybe:SELECT id, path FROM items WHERE PATH_EQUALS(id, path));or maybe something else altogether. This should return:ITEM_ID PATH------- -------1 02 0:13 0:1:24 0:1:2:3

Set up a trace with the events RPC:Completed, SQL:BatchCompleted, SQL:BatchStarting, and SQL:StmtCompleted.
When I issue the statement: SELECT * FROM XyzView there is nothing captured in Profiler. If I script out the view and then execute the select statement that defines the view, it does show up in Profiler.
I've tried adding a lot of the other events, i.e. SP:StmtCompleted and the various other StmtStarting events and the trace still does not capture anything.
Am I capturing the wrong events or is this known behavior? My goal is to see what the overhead is for using a view versus persisting the results of the view as a table and referencing that instead. The view in question is against static data, joins 9 tables, and is referenced a lot.
I can use the stats generated when I execute the select that defines the view but I still find this to be curious behavior so I assume I'm doing something wrong.

I am trying to load all the MDX queries that run on a Analysis Server instance into a database for further analysis. A SQL Profiler is setup which captures the MDX queries, and when I am loading the Profiler info to database, some of the queries are not coming up in full length.The TextData field doestn't show full MDX query. When loading to the database, the field is next data type. Is there any workaround to get the complete MDX query?Â

I have created a "parent" table with various columns and added an extra detail row to drop a nested subreport into the table passing parameters into the sub in order to obtain the child subreport. The problem is that the the while I can line up the columns in the sub report with the parent report,
I observe something like this:
parent columns:
a b c d e f
child columns
a b c d e f
The problem is in the last column of the parent "f" it appears stretched out for some reason-about an inch even though can grow is set to false.
Its like the child is forcing the parent's last column to expand yet when i observe the border around the table in the child the "f" is clearly more narrow than the parent's f despite my matching the column widths in the layout exactly the same . In preview mode, the parent's last column is extended width-about an inch more was added. Note I tested it with No data in the child's last column and it still expands the parent column by that inch.
Also note when I dropped the subreport into the parent report I'm merging the cells on the detail row that the subreport fits across columns a, b, c, d, e, f.
So even though the subreports data lines up properly under a, b, c, d, and e; the parent's "f" still expands outward.
Any clues or suggests on what I should consider changing. I'm stumped.

Hi all!
I am trying to organize a hierarchical data structure into a table. I need to have the possibility to set 2 parents for some nodes. Curently I see following two options:
Example 1
id parent_id name-----------------------------------1 0 Level 1 Parent A2 0 Level 1 Parent B3 1,2 Level 2 Child
Example 2
id parent_id name-----------------------------------1 0 Level 1 Parent A2 0 Level 1 Parent B3 1 Level 2 Child3 2 Level 2 Child
Is any of the two examples valid database logic wise? In fact, is it possible to achieve the requirement by using only one table?
Thanks in advance,

I need to extract data to send to an external agency in their supplied format. The data is normalised in our system in a one to many relationship. The external agency needs it denormalised.
In our system, the parent p has p_id, p_attribute_1, p_attribute_2, p_attribute_3 and the child has c_id, c_attribute_a, c_attribute_b, c_parent_id_fk
The external agency can only use a delimited file looking like
p_id, p_attribute_1, p_attribute_2, p_attribute_3, c1_attribute_a, c1_attribute_b, c2_attribute_a, c2_attribute_b, ...., cn_attribute_a, cn_attribute_b
where n is the number of children a parent may have. Each parent can have 0 or more children - typically between 1 and 20.
How can I achieve this using SSIS? In the past I have used custom built VB apps with the ADO SHAPE command but this is not ideal as I have to rebuild each time to alter the selection criteria and and VB is not a good SQL tool.

I have made an SSRS report using the recursive parent functionality to show a hierarchical tree of values. The problem I have is that some children have more than one parent, but because (in order to use the recursive parent nicely) I need to group the results by Id, I only see distinct entries. This means that I only see each child once, even if it "should" appear in multiple locations in the report (under each of its parents).

Hi,
I'm trying to debug a vendor package and would like to turn on JDBC trace (either client or server side). The only information I found is DBCC TRACE which seems not very useful (I even don't know where the trace result located). Any help is appreciated!
Env: Windows Server 2003 & SQL Server 2000 8.00.818.

hi all..
i have 2 tbl..
-- Prepare sample data
DECLARE@tbl1 TABLE (box varchar(10), loc varchar(5) )
INSERT@tbl1
SELECT'P1', 'aa' UNION ALL
SELECT'P1', 'bb' UNION ALL
SELECT'P1', 'aa' UNION ALL
SELECT'P3', 'cc'
DECLARE@tbl2 TABLE (box varchar(10), loc varchar(5) )
INSERT@tbl2
SELECT'P1', 'aa' UNION ALL
SELECT'P3', 'cc'
--expected result
SELECT 'P1' as box, 'aa' as Location, 'aa' as HeaderLoc UNION ALL
SELECT 'P1' as box, 'bb' as Location, 'aa' as HeaderLoc
how do i trace from @tbl1, that has 1 Box with more than 1 Location?
in this case P1 has 2 distinct location (aa & bb).. and left join in the loc from @tbl2 just to retrieve the loc for that box..
~~~Focus on problem, not solution ¯(º_o)/¯ ~~~

Hi,
I'm trying to use trace flag 1204 to get some detailed deadlock information
In EM, I add startup parameter -T1204, and then I stop and start the server.
I run two jobs that I have setup to deadlock, and they do. But no information about the deadlock is in my sql error log? anyone know what I am doing wrong? thanks.

Hi ,
I want to trace the deadlock information. I am enabling trace flags 1204 ,1205. Is there any difference in setting these trace flags by using DBCC
TRACEON and by setting them at command prompt by statrting the SQL server with SQLSERVR command. Actually i don't want to bring the server down. I want the information to be logged to Error log. Any help is greatly appreciated.

Hi all,
I was wondering how much of an overhead would Running this
trace (1204) have over the system. Will my perfomance
degrade significantly. If yes, by what percentage ???
The trace is 1204 to keep a watch on DeadLocking
I am running this command
C:mssql7innsqlservr -T1204 /dc:mssql7datamaster.mdf
How much performance degrade are we talking about here ?
The Application is Peoplsoft and the db sizes is about 10
Gb !!

Hi All,
I've just joined a project for improving performance issue on MS-SqlServer(6.5).
I was DBA Sybase a couple years ago I am unsure that MSSQL works in a manner as
Sybase. I want to change some configuration options (sp_compile) and modify
the table and indexes definition for improving the performance and avoid having
deadlocks.
Is true that :
When field, which has a default value assigned to NULL, is equal
at a variable-length field and when you execute an update on it you will
get 2 transactions : first a delete and then insert ?
(On Sybase there is the concept of Index Covering to avoid that overhead
what about Ms-Sqlserver 6.5).
To avoid having deadlock I want to use the FILLFACTOR I think this option
is usefull only on cluster indexes, that's right ?
For huge tables the order of fields is important :
first position put the primary key field
after put the FK, secondary key, short type field (tinyint,int,datetime...)
go on with the alpha fields (char) NOT NULL
at last the NULL fields
Is that design efficient for Ms-SQLserver ?
Many thanks,
Herve
