I'm building a web site. there is a database.
I've set a primary key and unique of a field.also I set it to auto numbering.
Everytime I insert a record , that field will increase 1 (type bigint , start from 1).
After lots time of inserting record , the id going to be larger number.. I wondering how can I reset that to zero?
After deleting all the test data from all tables in a SQL 2000 database, is there a way to reset all the auto-incrementing fields back to zero in one shot? In Access, you can run the Compact and Repair option. Also, in Sybase SQL, there was an "unload/reload" option to reduce the database size. Is there a similar function in SQL2000? Thanks for all the help

Every night, there are some stored procedures that run to recreate tables so that the information in the table is updated. After the tables are droped and recreated I have to go in and check the select box under the permissions for the public role. If i don't do this users will not be able to select from theres tables.
What can I do so that users are able to select from these tables after they are created?
Would you be able to specify the select permissions for the public role in the script that creates the table or run a script that gives all those tables select permissions for the public role?
All help is appreciated.
I am restoring a production copy of db XYZ to the development server db XYZ. I want to retain the original users on the development server for db XYZ. How do I create a script that will reset the users on the development server with the same permissions and access they had before the production copy was restored on development? I have searched and searched and cannot find the answer. I can use a third party tool - Embarcadero - to script out the create and update stmts but it is not 100% correct. I end up having to do alot of manual work.
any assistance would be greatly appreciated.
thanks
I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.
need help

Let say I have 6 tables. I want to autogenerate the PK for each table and that is unique for each table and cant be duplicated on other tables. Let say I have table with PK of 1, so table2 to table6 wouldnt have a PK of 1. If table2 have a PK of 2, table1, table3 to table6 wouldnt have a PK of 2. Same for others. Identity will not be appropriate. Will 'uniqueidentifier' data type suffice? How bout guid? Or what must be my datatype? Or what will I do to implement this? Any links? Thanks

I have a little problem with DB, I'm using MS SQL 2005 Express edition.
I have a few tables in my DB, every table contains a list of objects and I need unique ID for every object, I can do it for one table, but not for more then one.
Is there any solution for this problem?

Hello,
I would like to store some frequently asked questions in a database.
As those questions/answers could be translated in several languages, I was thinking of using two tables :
The first table would contain a unique field : the key wich is an id for each faq.
The second table would contain those fields :
FAQ_ID : foreign key
LANG : language
QUESTION : the question translated in the good language.
ANSWER : the answer translated in the good language.
What I find embarrassing, is that first table just contains a unique field : the id. But it allows :
- to have a table in which a line correspond to an object. It is convenient for object relational mapping.
- it is more evolutionary. If, in the future, I have to add some statistics that concerns a faq, I will have the possibility to store them in the first table, avoiding in this way to duplicate data.
But, one more time, I find a bit embarrassing having a table with a unique field...
What is your opinion about that ?
Thank you in advance for any suggestion.

View 8 Replies View RelatedI have a stored procedure that appends data from a temp table to a destination table. The procedure is called from an aspx web page. The destination table has an index on certain fields so as to not allow duplicates.
The issue I'm having is if the imported data contains some records that are unique and some that would be duplicate, the procedure stops and no records are appended. How can I have this procedure complete it's run, passing over the duplicates and appending the unique records? Since the data is in a temp table (which gets deleted after each append) should I run some sort of 'find duplicates' query, and delete the duplicates from the temp table first, then append to the destination table?
Thanks in advance.SMc
I need to to have a table that has a counter field (used to generate an id code for a record). This is not the primary id for the field but just a counter to label a record in another table, similar to a registration code for an event. This is a sequential counter that will start 1 and go up on each new record inserted into other tables. What I want to do is be able to query this counter table to get the next valid number and increment the count for the next time. This is a multi user web app so needs to prevent duplicate use of same number.How best should this be handled? A transaction to query and update the field?

View 1 Replies View RelatedHello,
I am using SQL Server 2005 and am having trouble with making a history table like mentioned in my earlier thread:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=102811
This is the table "People" I have created:
|PersonId (PK)|DateFrom (PK)|DateTo|PersonName|Other Attributes....
Each change to a person's attributes results in a new row formed with the same PersonId as in the row with old attributes and the Date these new attributes are valid (DateFrom). So as shown above the Primary Key is a combination of the PersonId and DateFrom as a change to a person's attributes should never happen at the same time twice.
My problem is when I want to create a new person, how do I get a new unique id? Ideally I want the a new incremented id, so that all peoples' ids are in a sequential order.
As always, thanks for the help!

Hi
I have a strange requirement in ETL operation. My Source contains only the details table data. Out of it, I have to load the master table and refer the Master table primary key ID to load Details table. I can easily load the Master Table with aggregate transformation. But problem is how to look up the Master Table Primary Key ID to load the Details table, as the master does not contains any unique key to lookup.
