Detecting A Change In A Particular Field In A Database
Nov 16, 2005
Is it possible, using VB code, to retain a user on a particular page
until the status of a certain field in a database is changed?
The scenario I am working on is that a person makes a reservation and
has to wait until that reservation has been accepted or rejected by the
administration.
Dim dsResv As DataSet
dsResv = objResv.DALgetResvStatus(resvId)
While (dsResv.Tables(0).Rows(0).Item("resvStatus") = "pending")
dsResv = objResv.DALgetResvStatus(resvId)
If
dsResv.Tables(0).Rows(0).Item("resvStatus") = "denied" Then
failure.Visible = True
LinkButton1.Visible = True
ElseIf dsResv.Tables(0).Rows(0).Item("resvStatus") = "reserved" Then
success.Visible = True
LinkButton1.Visible = True
End If
End While
This is how I tried to do it, but it doesnt seem to work.
Any suggestions?

I am using the Konesans Checksum transformation ( http://www.sqlis.com/21.aspx ) to detect changes in my big (many columns, type 2 SCD) dimensional table.
But I am running into collossions
The checksum transformation, sometimes misses a small change in the record, for instance when a certain flag is set or unset. Is there a more robust checksum generator? Of any other suggestions on to solve this?
thx

When I type Select statemet like below, Tables names are not populate auto. I need to type full lenght instead of selection in list.
Ex: I have few tables and database in my schema and need to select while coding.
select * from (Table Name) When i type first char in the table space it will not populate list of tables in my sql studio.

I have a table named PERSON and a field named PERSON_ID. How can I set this field to Autonumber? I know I have to use the IDENTITY command, but when I view this field in "design" view, all the IDENTITY options are grayed out.
How can I set this field with the IDENTITY properties?
Thanks

Hi, I'm new to SQL. I have to fix a table as follows:
update recruit.cvs_2 set cv_id = (cv_id + 11000) where change_date <> null
I'm trying to change the value of cv_id e.g. 2 +11000= 11002. cv_id is defined as nvarchar. What am I doing wrong?

I had a profile element named "Country", however, I want it to be named "CountryId". I can change this in the web.config with no problems, but then I need to update the code manually any place Profile.Country is referenced. Also, it seems I would have to write some SQL to update all the values in the profile table from Country to CountryId. Is there an easier way to do this? I'm using Visual Studio 2005 and SQL Server Express 2005.Thanks,Wes

I have a database on sql2000. I want to change the length of a field in Table A, but it is related to another field in Table B. When I tried to change the length of the field in Table A via
ALTER TABLE table ALTER COLUMN field varchar(5).The query analyzer generates the following error.
Server: Msg 5074, Level 16, State 8, Line 1
The object 'UQ__table__77BFCB91' is dependent on column 'field'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN field failed because one or more objects access this column.While when I tried the same query on the field in TABLE B, the query completed without any errors.

The title says it all. I've used ALTER DATABASE, and ALTER TABLE...ALTER COLUMN to change all my character fields from 'Compatibility_42_409_30003' to the default I want ('Latin1_General_CI_AI') on databases converted from SQL7. Now I just have these ntext fields to change...

I have to modify field length in the table, which is part of publication. I tried to use an Enterprise Mgr and received an error message because that table is scheduled for replication.
Is any way around this beside temporary stopping and restarting replication? And actually how to do this to be sure that after restart the data will be again in sync.
We have SQL Server 2000 Enterprise Edition and Windows 2000 Advanced Server.

Hi,
My table has more columns than this but I will just use the ones here tht are important.
I have two columns in a table these are "ExpiryDate" and "Archived".
When the row is created the "Archived" field will be null but the user will have entered a expiry date. When this date is reached I would like the "Archived" data to change to "1". Is this possible? Would I have to do it through some kind of script or can I set the database to do this automatically?
Thank you, Mark

My value is approx 50 characters wide, the parameter drop down is only displaying about 10 characters, although I have plenty of room on the screen.
Also, in a multi-parameter environment, are there any controls on where the parameters are being displayed?

Hi,I use view to join difference table together for some function. However,when the "real" table fields changed (e.g. add/delete/change field). Theview table still use the "old fields".Therefore everytimes when I change the real table, I also needed open theview table and save it by SQL enterprise manager manually for update theview table field.Can we use a SQL command or other method to update it directly?Regards,Silas

Hello all,
Is there a preferred method for detecting SQL Server 2005 SP2? I do installation/deployment and during my install script I would prefer to skip the SP2 install if the instance is already upgraded.
I had tried to check HKLMSoftwareMicrosoftMicrosoft SQL ServerInstance NamesSQL to first find out what MSSQL.[n] our instance took.
After that I was attempting to check HKLMSoftwareMicrosoftMicrosoft SQL ServerMSSQL.[n]SetupSP but there have been cases where the key SP did not exist.
I decided I could just install it under the condition that no key existed at all, assuming since the 'SP' key did not exist, the instance was not upgraded. In tests however, after a fresh install of SP2, the key was not there.
I guess the question is further defined as: does installing SP2 place a flag that it exists anywhere else? Is it supposed to write to HKLMSoftwareMicrosoftMicrosoft SQL ServerMSSQL.[n]SetupSP?
Thanks,
-Mike

I am trying to use DDL triggers to detect all changes to a table.
Sometimes a user directly or (more likely) through the SQL Server Management Studio GUI renames a column via sp_rename.
I can't seem to figure out how to detect such renames using a DDL trigger. Is there any way or is this a limitation of the DDL trigger system?

Edit: Newer mind. I tested this query more after writing this, and now it seems to work!I hope it continues to work. In following query, else is never executed.CREATE PROCEDURE Put_into_basket( @Product_code varchar(20))ASBEGIN SET NOCOUNT ON;IF NOT EXISTS(SELECT * FROM dbo.t_shopping_basket WHERE Product_code=@Product_code) BEGIN INSERT dbo.t_shopping_basket (Product_code, Name,Price) SELECT Product_code, Name,Price FROM dbo.t_product WHERE Product_code= @Product_code ENDELSE --this part is never executed BEGIN UPDATE dbo.t_shopping_basket SET Quantity=Quantity+1 WHERE Product_code=@Product_code ENDENDGO The query should test if there is a record or row with Product_code=@Product_code. If there is not, that is the first part, one such row is inserted. Quantity has a default value of 1. Insertion works, one row is inserted. At least sort of. If there is already record, That's later part, Quantity is increased by 1. That too works, if ran separately.But when I test query, it never runs the quantity+1 part.

Can anyone provide me with some SQL that will identify rows from a table where a varchar column named "Notes" contain Carriage Returns?
I know that with report writer SQR I can translate CR's to white space but I do not know of any Sybase function that will allow me to do the same, any ideas on this well would be appreciated.

I have 2 tables:
Table 1 Customers with column CustomerId
Table 2 Purchases with columns PurchaseId and CustomerId
I want to select all customers who have made just 1 purchase, what would be the sql for that? I know I can join the tables to get the customers with purchases, but I don't know how to limit it to those with just 1 purchase (and exclude all the other customers).
