Hello to everyone:
Aside from using a trigger to automatically update a Foreign key,
is there a way you can automatically update a Foreign key when you
update its corresponding Primary key using the select statement?

Hi,
I want to upsize my Access backend to SQL Server, and there is a simple query which works fine in Access but not in SQL Server:
There are two tables: Person and ArtificialPerson (a more specific Person). They are linked through the Person_ID attribute (Primary key in Person and Foreign key in ArtificialPerson).
I have a form in Access frontend having as recordsource a Select statement based on the join between these two tables. (Although this relationship is defined as 1-n in Access, I use it just as 1-1 in my form, so after a adding a new entry in the form I have a new entry in both tables)
The problem is the following:
Using SQL Server as backend, when I try to insert a new entry in the form (or in query used as recordsource for the form) the Person_ID isn't automatically inserted as foreign key.
My question is why using Access tables the Foreign key is automatically inserted and using SQL Server it does not work ?
Thanks in advance

Hi I'm currently running a complex MSSQL query (using SqlDataSource server control) everytime a web page is loaded to display a single value. How ever, this data only needs to be updated every 24 hours, therefor remains the same all day. I'm trying to figure out a way where by the MSSQL query runs once a day and the value is inserted directly somehow into my aspx page, or, failing that is inserted into an MSSQL database.I also have full root access to my server.thanks

View 3 Replies View RelatedOn a SQL 7 sp 2 server, I have a database with about about 77,000 records, with automatic update statistics on inserting 1000 records took 43 minutes. With automatic update off, it took 23 minutes to insert the same 1000 records. On the same machine, I inserted 1000 records into 2 other databases with the same database structure and automatic update statistics on. On the second database, there are about 174000 records and it took 35 minutes to insert 1000 records. On the third database, there are about 93000 records and it took 19 minutes to insert 1000 records.
Why is the time so high on the first database?
What can be done to fix the problem?
Thank you.
Hi. I have automatic statistic update turned on for all my databases. Isthis an overhead I can do without? Could I update them overnight when thedatabase is hardly in use?Thanks--Chris Weston

I finally added WinXP SP2 to my system yesterday (along with a lot of other security updates/patches through Automatic Updates) and now my backups and data exports are failing. Further, when I open my "Enterprise Manager" and try to export data ("All Tasks-Export-...") using the Import/Export Wizard, it won't let me select the "Export From" database.

I have 2 tables Publication and Advertisment_Codes. I want to update the publication_code in both tables where country_id=1 and publication_code='A'. However, it gives me an error because of foreign key relationship. I tried first updating in Advertisment_Codes and then in Publication table but it didn't work. I tried the other way round but also it didn't work.
How can I update the publication code?

Hello,
I would like to update foreign keys using triggers. At least thats what I think is the solution when having multiple references to a table in order to avoid the "cycles or multiple cascade paths" error message.
Anyway, here are three tables
Dentist table
dentist_id int identity (auto increment)
Patient table:
patient_id int identity (auto increment)
Appointment:
apointment_id int identity (auto increment)
id_dentist int FK to dentist_id
id_patient int FK to patient_id
I am gooling but cant find a way to make a trigger run only when the dentist_id from dentist table is updated. Also, is there a way to get the new id and old id somehow? I saw some posts with new.dentist_id and old.dentist_id but apparently is not for sql server.
Thank you.
is there a way to cascade update to foreign keys where both fields (PK & FK) are located in two different database?
View 2 Replies View RelatedWe need to import data from flat/xml files into our database.
we plan to do so in bulk as amount of data is huge, 2GB+
we need to do some validation checks in our code after that we create insert queries.
We have identity columns that are used as foreign keys in child tables. Question is how can I write a bulk/batch insert statement that will propogate the identity column to the child, as for all other we are creating the query in the application memory.
there are 2 parent tables and 1st table value needs to be referred to in 7 tables and second table's value in 6.

Hi,
We are working on creating an automatic backup tool for our web application. Our goal is to run a script that "zips" the virtual host/application directory. We have the script to zip the application directory, but is there a way to run a SQL Backup and then zip the output easily? This is where we are struggling.
Any Suggestions are appreciated

I am getting an automatic rollback in a transaction that fails to insert a row, via a trigger, due to a duplicate key. The transaction is automatically rolled back and unless the error correctly handled a 'partial update' occurs. Why in the example below is the transaction automatically rolled back (statements 1 to 3) and is there any way of knowing what errors generate an auto rollback. For example if the duplicate key error occurs on the insert into table B below, and not the triggered update, then no auto rollback occurs.
Begin Tran -- 1
insert into A values ('A1') -- 2 updates OK
insert into B values ('B1') -- 3 updates OK
-- triggers insert into B_Hist -- 4 Fails with Duplicate Key error
insert into C values ('C1') -- 5 updates OK
Commit Tran -- 6 3902 error No corresponding Begin
Thanks.
Hi all,

I don't know very much about Sql Server and need help.
I have two primary keys called AirlineCode e ID in the same table.
This id is an automatic number. So I don't need to input this value, since
it's created automatic. What I need is this ID be created automatic but
for each new AirlineCode the ID starts as 1 again. For example :
If I put AirlineCode = 220 then ID starts as 1. In another row AirlineCode is
also 220, then ID is 2. But in another row AirlineCode = 500, then this
automatic number come back to 1.
then the rows can be like this :
AirlineCode ID
220 1
220 2
500 1
220 3
300 1
500 2
I think I have to create a script to make this, but I don't kwon how...
Ask someone to help-me

I have two sql 2000 server tables one is active and one is terminated (I inherited this db) and I was thinking of having the active table automatically update the terminated table when an employee is terminated. Access is at the front end and in the form of the active table theres a drop down text box that has the employement status(active, terminated, on leave...etc) so when the status turns into terminated i want the acitve table to send those records to the terminated table, ( the data in both tables are not exactly the same). looking into a trigger or stored procedure. This is the first time I've done this so I'm doing some reasearch on how to handle it. Any suggestions
View 14 Replies View Relatedwell as I get further into this project of automatic updates I'm fining more and more barriers. The combo list box which indicates whether the employee is terminated or active might be a problem with sql since you cant create a Row source and a Row source type in a sql table. that combo box exsist in the properties of the form. The Row Source Type is a Value List. Shoot :(

Because of a reorganization I've got some new college's and lost some college's. My new college's think this is to much work, so it should be automated. They only want the failed jobs to report an error on a website or something like that, and don't want to check 40 servers. I don't agree in this, because I'm affraid I'm going to miss some errors.
How do you do your checks every morning?

Hi there,
