Logic Behind Object_ID

May 19, 2007


I have 2 basic requirements as below,

1) Comparing 2 versions of same database.
2) Keeping track of schema versions of Tables & Stored Procedures so that I can rollback to previous schema.

I have started with Sys.Objects, Sys.Tables & Sys.Columns and I kept things rely on Object_ID but the problem started whenever I change some part of Table. It assigns new Object_ID to the table whenever I change it; moreover creationdate of object is also changed. So I assume that it drops and creates new table.

Please throw some light on following questions,
1) When and How Object_ID Changes?
2) Is there any other thing in database which is Unique & Not Changing with alteration of object?
3) What should be the preferred way to Compare 2 Database?

I hate readymade tools as they charge per user and my requirements are very small.

Thanking you,

Object_id Numbers On Same Server

Aug 23, 2000

I restored a development database to a test database on the same server. I thought this would be a good
thing to do because testers would have the same data as developers and the tables would be exactly alike.
However, I noticed that the object_id is identical for the tables. For example, the Accounting Calendar in the development
database and the Accounting Calendar in the test database have the same Object_id. Could anyone verify that
this is or is not going to cause me trouble?

Help: Should Sys.service_queues.object_id Be Subset Of Sys.dm_broker_queue_monitors.queue_id?

Apr 4, 2007



I am having trouble sending messages between service broker, set up on 2 different machine ( different domain ). The ports on which service brokers listening are bidirectional.



for some reason the messages get piled up at the sys.transmission_queue and transmission_status seems to be empty.



I found the following link and tried to find status of all message queues.

http://msdn2.microsoft.com/en-us/library/ms177628.aspx

SELECT t1.name AS [Service_Name], t3.name AS [Schema_Name], t2.name AS [Queue_Name],
CASE WHEN t4.state IS NULL THEN 'Not available'
ELSE t4.state
END AS [Queue_State],
CASE WHEN t4.tasks_waiting IS NULL THEN '--'
ELSE CONVERT(VARCHAR, t4.tasks_waiting)
END AS tasks_waiting,
CASE WHEN t4.last_activated_time IS NULL THEN '--'
ELSE CONVERT(varchar, t4.last_activated_time)
END AS last_activated_time ,
CASE WHEN t4.last_empty_rowset_time IS NULL THEN '--'
ELSE CONVERT(varchar,t4.last_empty_rowset_time)
END AS last_empty_rowset_time,
(
SELECT COUNT(*)
FROM sys.transmission_queue t6
WHERE (t6.from_service_name = t1.name) ) AS [Tran_Message_Count]
FROM sys.services t1 INNER JOIN sys.service_queues t2
ON ( t1.service_queue_id = t2.object_id )
INNER JOIN sys.schemas t3 ON ( t2.schema_id = t3.schema_id )
LEFT OUTER JOIN sys.dm_broker_queue_monitors t4
ON ( t2.object_id = t4.queue_id AND t4.database_id = DB_ID() )
INNER JOIN sys.databases t5 ON ( t5.database_id = DB_ID() )



What I noticed is the values of sys.service_queues.object_id and sys.dm_broker_queue_monitors.queue_id are totally different. I am not sure whether this has any impact on why the messages are stuck at transmission_queue

Need Some Logic Help

May 10, 2008

Can anyone see where my logic may have gone a stray?
A user would be attempting to update a gridview row, I'm storing the amount of an item and the qty they purchased. If the order was for $150 and the grid has two item 1 x $50 and 2 x $50 the order already totals $150, so if the user tries to change the first item to a qty of 2 x $50 the total would be $200 and this would be more than the total payment or $150.
I want to then tell them they cannot do this.

Need Some Logic Help

Jan 6, 2004

Trying to bind some data to a datalist for a report.

User selects an Industry from a dropdown list and then I dump all records for that industry. However in order to parse some of the record field values into names (I.E. from a 1 to the actual company name) for some records I have to read TABLE_ONE and for other records I might have to read TABLE_TWO depending on the value of FIELD_ONE.

If FIELD_ONE = "A" then I get the NAME from TABLE_ONE.
If FIELD_ONE = "B" then I get the NAME from TABLE_TWO.
If FIELD_ONE = "C" then I get the NAME from TABLE_THREE.

I'm lost at how to get started on this. I thought about adding IF statements to my query but these won't work because I'm not passing in the value of FIELD_ONE ahead of time - it's part of the query. So I thought maybe I could do a pre-read and store all FIELD_ONE values in an ArrayList and pass these in as parameters, but the stored proc is only being called once - so that won't work.

Any thoughts on how I can do this?

Is This Right Logic

Jun 12, 2007

What i'm trying to do is if this column dt.IN_DIV_NO is populated take that value first if it's null than rr.AIQ_R_DIVISION_NO and if that column is null than rr.F_DIVISION_NO.

This is what i came up with, will it evaluate the way i need it to?

case When dt.IN_DIV_NO is not null then dt.IN_DIV_NO else case when rr.AIQ_R_DIVISION_NO is null then rr.F_DIVISION_NO end end as Current_DIV

SQL Logic

Mar 13, 2008

I have a logic problem,

I am selecting from a table

Select * from TAB_A
where state not in (1,4)
and create_date < '2008-01-01'
and
(
(x != 2 and y != 1 and z != 4) or
(x != 6 and y != 3 and z != 1) or
(x != 8 and y != 0 and z != 9)
)


then for example i am getting results where x,y and z is equal to one
or more of above combinations ?

Now i vaguely remember that using or with a != messes up the logic ?
if so can i use an NOR ? does it exist ?

Logic To Use

Mar 25, 2008



I am looking for the best approach to update a table's column based on the results of two other different tables. My tables structure is as follows.


Table 1 has columns A and B (tblemployee has location and employeenumber )
Table 2 has columns C and A (tblocation has locationID (identity) and location)
Table 3 has coumns C and B (tblcountry locationID (foreign key) and employeenumber.)

I want to update Table 3 (tblcountry) with the new locationID if and employee changes location or gets miscoded using an SSIS package.

Thanks in advance.

SQL Logic Problem

May 21, 2007

I'm trying to figure out how to track what messages have been read by what users in a message board program we wrote. The users are identified by an ID number and each message has a unique number.
Let's say there are 10000 users and 200,000 messages. What would be the database setup/logic to track every user as to what messages they had read or not read? Maybe I'm missing something but it does not seem to be a  trivial task.

Db Logic - Can't Put It Back Together

Feb 27, 2006

Hi there!
Hope somebody got some better insight into this problem than i have. I'm struggling with some db logic.
Overview:
I have a client who is a publisher. They would like to post all their advert-size specs for each magazine to their web site. My first thought was that ill be able to build one table and populate it with the information for each magazine. I was wrong. Each magazine comes in a different size. Thus each magazine will have different advert-sizes as well.
Layout for a magazine will look something like this:
Size              Trim          Type           Bleed
Full Page      280x440     270x430       290x450
Half Page     140x220     130x210       150x230
etc...
Some mags will not have values for Half pages since they dont print half pages and others will not have specs for Bleed.
Because of this - as an easy way out I created a table per magazine. It works but i dont think its very smart.
 
Break it down!
Ok so what im trying as a solution is to have three tables. The 1st table will hold the magID and Size values (e.g Half Page). The 2nd table will also have the magID and the Trim, Type, Bleed info. The 3rd table holds magID, sizeID, specID and the actual value (140x220).
I thought that this would be better because within these three tables i can store the information for each magazine regardless of their differences. Brilliant!
 
The Problem.
The problem comes when i have to put it all back together again. I need to represent this data in a table so i can bind it to a datagrid. I have NO idea how to do this. What i THINK i need to have is some temp table created on the fly. The row names for this temp table will come from the 1st table. The column names will come from the 2nd table and the values for each field will come from the 3rd table bound by foreign keys.
I've somewhat managed to do this with INNER JOINS. But it doesn't give the desired result. I need to set row and column NAMES using tables 1 & 2 then populate the columns with table 3, then bind to a datagrid.
 
Any ideas on how i could manage this?
 
If you made it tis far through my question then thanks anyways! I hope you can help me out!

Complex Sql Logic... Need Help

Feb 15, 2007

okay;

i have a table called tblSlots
tblSlots is a list of Start datetimes and End datetimes.
every day has the same list of 10 slots.

tblSlots:
PKSlotINDEX
datStartTime
datEndTime

then i have a table called tblPersons

tblPersons:
PKPersonINDEX
txtLast
txtFirst

then i have a table called tblSchedule

tblSchedule:
PKScheduleINDEX
fkSlotINDEX
fkPersonINDEX

i want to write a query that takes any one specific person's schedule for an entire specific day, adds an arbitrary number of days to datStartTime, and finally inserts the PKSlotINDEX corresponding to the calcultated StartTime and fkPersonINDEX.

wow complicated isnt it...

the goal is to take the schedule of one day for one person and copy it to another day; i can scrap my current layout if necessary.


thanks!

Help With JOIN Logic...

Jul 27, 2004

Arrrgggg, nothing makes any sence any more. I need to write a select statement that will display results based on one of two things...

Zip Code OR City State

By the way this is a Table of addresses with zip codes, I also have a Lat/Long table associated to all the different zip codes that need to be joined.

The Psuedo code is somethinglike this...

SHOW All People WITH Appropreate Longditude and Latitude
Who Live
In @This ZipCode
OR
(In @State AND @City)

-------------------
Table Dealers
-------------------
dlrID - varchar
dlrName - varchar
dlrAddress - varchar
dlrCity - varchar
dlrState - varchar
dlrZip - varchar
dlrCountry - varchar
-------------------

-------------------
Table ZipCodes
-------------------
zipCode
zipCity
zipState
zipCountrty
zipLat
zipLong
...
-------------------

I have achieved this with Joins but the query takes 2+ minutes to execute

What am I doing wrong??? I am sure there is a better approach to this!

Thanks,

Logic Problem

Oct 9, 2006

Hi,

This might just be my brain not working after the weekend, but I'm having problems working out just how to do this.

The table:

CREATE TABLE [dbo].[tblQuiz] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[q1] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q2] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q3] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q4] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q5] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q6] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q7] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q8] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[quizdate] [datetime] NULL ,
[ipaddress] [nvarchar] (50) COLLATE Latin1_General_CI_AS NULL ,
[sessionid] [nvarchar] (50) COLLATE Latin1_General_CI_AS NULL ,
[score] [int] NULL
)



The field [q5] has one of three values in it: "Happy", "Unhappy" or "Neither".

I have a list of about 50 session ID's. If a record in [tblQuiz] has a [sessionid] that matches one in this list, then:
if [q5]= 'Happy' then change it to 'Unhappy'
if [q5]= 'Unhappy' then change it to 'Happy'

The only way I can think of is to change all of one matching record type to some other value, then change all the other type, then change all the original type back to the other type. Which doesn't make much sense even when I've written it down, much less when I'm doing it and have to remember where I'm at. Is there a better way?

Query Logic - SQL Help

Jun 8, 2007

I have some table data and know how I want the results but I'm just having a bit of trouble in constructing the SQL logic to obtain the desired results. There's a site where visitors are able to select from a list of parts, and it will return a set of model/products that they can produce with the selected parts. Here's the data ...


tblModel tblPart
ModelId ModelName PartId PartName
---------------------- ----------------------
1 Alpha 1 CHOO1 Stem
2 Bravo 2 BH034 Rod
3 Bravo Pro 3 HRE Seat


tblModelPart
ModelPartId ModelId PartId
---------------------------------
1 1 1
2 2 1
3 2 3
4 3 1
5 3 2
6 3 3


... and here's the logic that I'm trying to implement, assume that the user selects from a form, parts with the PartId 1 and 3 ...

1. Return all models that contain only the parts selected.

ModelId ModelName
---------------------
2 Bravo

2. Return all models that contain the parts selected, and may contain other parts.

ModelId ModelName
---------------------
2 Bravo
3 Bravo Pro

... so do you have any idea on how the SQL would look for either of these queries?

Thanks in advance,
Goran

Table Logic?

I am just getting started with the integration between SQL Server and ASP.NET 2. I am at a loss of how to move data in and out.

I need to track a vehicle inventory, properties to be track are, year, make, and model, color and so on. These have not presented me with much of a problem; however the vehicle options have left me totally confused.

I have an Options table and a Vehicle table. The Options table has a numeric primary key OptionsID, and a field for the option. The Vehicle table has a numeric primary key, VehicleID. I have tried using a join table named VehicleOptions with two fields, VehicleID and OptionsID. I have tried a join table (VehicleOptions) with a field for the VehicleID and separate fields for every OptionsID, inputting true or false, as needed.

I have tried passing a string with each OptionID separated with a comma, to a stored procedure, parsing the string, looping through setting the value to true or false as needed.

I have also tried matching the VehicleID with the OptionsID in the code for the web page then passing this to a separate stored procedure.

Thanks in advance for any help?

Query Logic

Apr 14, 2008

Hi, sorry for a newbie question but I was wondering if the following is possible:

I have to select some information from a table which I have already created a query for. This information then has to be inserted into a new table but needs another column (not the promary key) with another unique custom identifer for each record in the format EX01 which is incremented by 1 for each record. I was wondering how is it possible to do this?

My approach was to create a view and then insert the values form the view into the new table but I still have no idea how to do the unique identifer. Was the first part of my approach correct or have been wrong from the start?

Sep 14, 2006

I have a little system of 3 tables Job, employees and times. This times table has the fields times_id, employee_id and job_idI'm trying to have a query that pull of employees that don't have a certain job_id yet. I'm going to put this data in a table so the user knows they are available for that job. The code i have isn't working, and i'm not sure why.SELECT DISTINCT times.employee_id, employee.employee_nameFROM employee INNER JOIN times ON employee.employee_id = times.employee_id WHERE (times.job_id <> @job_id)  Thanks in advance for any help. I'm sure I missing someting silly, or maybe i need to have a stored procedure involved?... Thanks!

Commit && Rollback Logic In VB.NET

Oct 27, 2006

I have several sets of code that need to delete rows from more than one database at a time. The rows are basically linked without being identified as having a foreign key. This means I issue two deletes. If one fails, especially the second one, there is no way to roll the first delete back.Can someone either point me to some code that enables me to link the deletions, allowing me to insure that both are successful or both do not occur. I cannot identify any fields on the secondary database table as specifically linked to the primary, as the secondary database is a storage medium for images, that may be linked to more than one different table.TIA for any opinions, options, etc.  Tom
