Name Value Pair
Mar 12, 2008
Hi,
I need to display a dataset where everything is dynamic.
e.g. I have a table with columns "Code", "Description" and "Inspected" and
another table with columns "UserCode", "Name", "PostCode" and "Town" etc
And I need to dislay data like this from a single db proc with parameters:-
(TableName, ColumnName, ColumnValue)
Procedure called with these parameters (CodeTable, Code, TD001) would return
a dataset like this:-
----------------------------------
|Code | TD001
|Description| Printer
|Inspected | Y
---------------------------------
Not
----------------------------------
|TD001
|Printer
|Y
---------------------------------
Procedure called with these parameters (UserTable, UserCode, CP1) would
return a dataset like:-
---------------------------------
|UserCode | CP1
|Name | Charles
|PostCode | 2000
|Town | Sydney
---------------------------------
Not
---------------------------------
|CP1
| Charles
| 2000
| Sydney
---------------------------------
Any ideas how I would code the database proc, I did consider using XML but
not sure.
Thanks

Hi folks,
I am trying to write a query to get data in pairs, for example, i have data like this:

2 24-B
3 24-C
4 25-A
5 25-B

I want to store many different types of objects in a single table. Iwas thinking of using the name value pair approach to achieve this.Does anybody have any experience with a such a design?The table might look like thisCREATE TABLE NV (pk int, type int, [name] varchar(100), valuevarchar(100))--Insert a manager - type = 1INSERT INTO NV (pk, type, [name], val)VALUES (11, 1, 'FirstName', 'John')INSERT INTO NV (pk, type, [name], val)VALUES (11, 1, 'LastName', 'Smith')INSERT INTO NV (pk, type, [name], val)VALUES (11, 1, 'Position', 'CEO')--Insert an employee - type = 2INSERT INTO NV (pk, type, [name], val)VALUES (21, 2, 'FirstName', 'Joe')INSERT INTO NV (pk, type, [name], val)VALUES (21, 2, 'LastName', 'Blog')INSERT INTO NV (pk, type, [name], val)VALUES (21, 2, 'Position', 'Developer')--Insert an inventory item - type = 3INSERT INTO NV (type, [name], val)VALUES (13, 3, 'Name', 'Chair')INSERT INTO NV (type, [name], val)VALUES (13, 3, 'Color', 'White')INSERT INTO NV (type, [name], val)VALUES (3, 3, 'Price', '$150')

Hi,
I have to log the Details of the incoming xml message into databse.
But the values logged will vary with the message.So I cant fix the mumber of columns.
I thought of using table in which the fields are logged as Key-Value Pairs. The table looks as below.
TransactionID ColumnKey ColumnValue
1111 PONumber 123
1111 Sender xxx
1111 Recever yyy
using dynomic query i was able to get the results as follows
TransactionID PONumber Sender Receiver
1111 123 xxx yyy
Till now every thing was fine. but now i got new requirement where i have to identify each column with its parent. For example if we consider the line items of the PO, table may look like below.
TransactionID ChildKey ChildValue ParantKey ParantValue
1111 PONumber 123 null null
1111 Sender xxx null null
1111 Recever yyy null null
1111 ItemName soap ItemID 123
1111 Quantity 4 ItemID 123
1111 UnitPrice 2.2 ItemID 123
1111 ItemName Brush ItemID 222
1111 Quantity 5 ItemID 222
1111 unitPrice 4.4 ItemID 222
I am unable to design the database which satisfy the requirement of the reporting.
I not even know how to query the data which is logged like this.
Help me by giving the inputs to design databse for the above problem and to query the data .
advance thanks

I have a table, gdbdoc, that contains record-key pairs, linking records in another table. There is no significance in the order of the link: if records A and B are linked, then I don't care whether the link is A -> B or B -> A, and my normal query logic is SELECT ... Where DCIindiid = A ... union SELECT ... Where DCILinkid = A(DCIindiid = key1, DCILinkid = Key2)
The link-creation process normally checks whether there is already a link in either direction. Thus before creating a link A->B the logic checks to see whether either the A->B or B->A link record exists, and a new link is not created if the link already exists in either direction. However recently one of my processes bypassed the reverse-link check, and I've ended up with a few hundred cases where there is both an A->B link and a B->A link.
If I run a query: - select gd1.* from gdbdoc as gd1 join gdbdoc as gd2 on gd1.dciindiid = gd2.dcilinkid and gd1.dcilinkid = gd2.dciindiid
this displays all the records where one record links A -> B and there is also another record that links B -> A.
How do I write a query to delete ONE of the pair of duplicate records? I have two problems: -
Problem 1: Table gdbdoc is keyed on (DCIindiid, DCILinkid). Both guids are needed to create a unique key, and the table does not have a single key field. You can't write DELETE gdbdoc where DCIIndiid, DCILinkid IN select gd1.dciindiid, gd1.linkid from gdbdoc as gd1 join gdbdoc as gd2 on gd1.dciindiid = gd2.dcilinkid and gd1.dcilinkid = gd2.dciindiid
as the DELETE ... SELECT ... syntax only seems to support a single returned value.
Problem 2. If we solved problem 1, we would (I think) delete BOTH the A->B link and the B->A link , whereas I only want to delete one of these links.
Afterthought: Problem 2 seems easily solvable: add "Where gd1.DCIindiid < gd1.DCILinkid" to the DELETE ... statement. Although the concept of "<" doesn't really mean anything with a guid, this is accepted by SQL, and halves the number of records returned by the select. Obviously I don't care which of the two links (A->B or B->A) is deleted.

my page suddenly stopped working when I wasn't working on it and it seems to be down to the 'ORDER BY' part of my SQL. I'm here alone as usual and I need someone to glance at the sql strings below. (yes, I do need the select *)
If I run this in SQL Manager it works fine:
SELECT * from dest_search WHERE trip_type like 'Trekking' ORDER BY start_date
if I do the same from my asp page it fails but if I leave out 'ORDER BY start_date' it works.
the error I get is:
Microsoft OLE DB Provider for SQL Server error '80040e21'
Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
/Newindex/trip_types.asp, line 53
line 53 is the 'desc = oRS...' bizarrely
oRS.Open strSQL, oConn, 2, 3
oRS.moveFirst
Do while not oRS.eof
country = oRS("country")
53---> desc = oRS("description")
url_link = oRS("url_link")
startDate = oRS("start_date")
endDate = oRS("end_date")
trip = oRS("trip_type")
difficulty = oRS("difficulty")
not all the descriptions are filled in (some are null) but that doesn't stop SQL manager from working or unordered results coming up fine in my web page.
any comments gratefully received thanks.

Hi Folks,
I would like to create a table with primary key pair:
Key1 : nchar(10)
Key2: nchar(10)
Value: money
That is, Key1 and Key2 are the primary key columns for the table. I would like to think of (Key1='Foo', Key2='Bar') to be the "same" as (Key1='Bar', Key2='Foo'). Is there a way to enforce this as a table constraint, or do I have to enforce this manually in all procedures that modify and read the table?
Thanks!

I'm working with a table that I've created called Config which contains key/value pairs used to get and set site-wide settings. I'm now trying to create a web form which updates the table but I'm not sure how to create the most effective UPDATE query.
Table of course takes this form key | value
---------------------------------
config_setting1 | value1
config_setting2 | value2
I'm working with a System.Collections.Specialized.StringDictionary Class object which contains all of the pairs from my webform... anybody have a creative way to build an UPDATE string using this object???
Thanks for any help and suggestions,

I can only do one match at a time -- Like can only do either the sql_statement_(start and end), or sp_statement_(start or end). Is there any way to capture both in the same session? Or since I am adding both the events in the ADD EVENT section, can I query it somehow to get unmatched SP or SQL?
Code:
USE master;
GO
-- Create the Event Session
IF EXISTS(SELECT *
FROM sys.server_event_sessions
WHERE name='TimedOutSQL')
[code]...

I am trying to create an exception report that will show the difference between two versions of the same row. (Combination of two different sources in sql, with source 1 having childID = 0 and the other source having childID = 1; parentID is the link between them)
The results are as follows:
ParentID - ChildID - Col1 - Col2 - Col3
1 - 0 - AA - BB - CC
1 - 1 - AA - BF - CC
2 - 0 - GG - NN - TT
2 - 1 - DE - NN - TA
3 - 0 - etc
3 - 1 - etc
4 - etc
How can I render the differences in red in RS?
