I created a table with a field called myID. I set the data type as "uniqueidentifier", but it won't auto generate. How do I create a field to auto generate a unique number? I'm working with SQL Server 2000 and I'm creating the table from Enterprise Manager.

Hi does anyone know how to create a sql table and then import a list by just clicking on a button to call a procedure?CREATE TABLE clients(ClientID VARCHAR(5), ClientName VARCHAR(30), PRIMARY KEY (ClientID));LOAD DATA LOCAL INFILE 'C:/client.csv' INTO TABLE clientsLINES TERMINATED BY '
';
Hi everyone,
I know that statistics called _WA_... are created on tables when auto create statistics is set on a database. Is this an indication that queries against the table would perform better if indexes were created on the columns in question? (The tables I'm interested in optimising are used equally for transactional querying and reporting)
Thanks for any replies!

For my company, we have made it a standard to create history tables and triggers for the majority of our production tables. I recently grew tired of consistently spending the time needed to create these tables and triggers so I invested some time in creating a script that would auto generate these.
We recently launched a project which required nearly 100 history tables & triggers to be created. This would have normally taken a good day or two to complete. However, with this script it took a near 10 seconds. Here are some details about the script.
The code below creates a stored procedure that receives two input parameters (@TableName & @CreateTrigger) and performs the following actions:
1) Queries system tables to retrieve table schema for @TableName parameter
2) Creates a History table ("History_" + @TableName) to mimic the original table, plus includes additional history columns.
3) If @CreateTrigger = 'Y' then it creates an Update/Delete trigger on the @TableName table, which is used to populate the History table.

I would like to create auto-generated "string" ID for any new record inserted in SQL Server 2000.

Could anyone know how to do that?? Thanks!!

I would like to create a auto relationship between tables.

Hi,I'm a newbie to sql server and this may be a really dumb question forsome you. I'm trying to find some examples of sql server triggers thatwill set columns (e.g. the created and modified date columns) if the rowis being inserted and set a column (e.g. just the modified date column)if the row is being updated.I know how to do this in oracle plsql. I would define it as a beforeinsert or update trigger and reference old and new instances of therecord. Does sql server have an equivalent? Is there a better way to dothis in sql server?Thanksericthis is what i do in oracle that i'm trying to do in sqlserver...CREATE OR REPLACE TRIGGER tr_temp_biubefore insert or updateon tempreferencing old as old new as newfor each rowbeginif inserting then:new.created_date := sysdate;end if;:new.modified_date := sysdate;end tr_temp_biu;

I created a cursor that moves through a table to retrieve a user's name.When I open this cursor, I create a variable to store the fetched name to use within the BEGIN/END statements to create a login, user, and role.
I'm getting an 'incorrect syntax' error at the variable. For example ..
CREATE LOGIN @NAME WITH PASSWORD 'password'
I've done a bit of research online and found that you cannot use variables to create logins and the like. One person suggested a stored procedure or dynamic SQL, whereas another pointed out that you shouldn't use a stored procedure and dynamic SQL is best.

The upgrade adviser for for 2k5 says something about derived tables being handled differently between 2k and 2K5 and it says to query the tables directly but this does not seem to make much sense because I thought FOR XML AUTO just created some generic XML for presentation purposes. These 2 stored procedures that it is complaining about do query the tables directly and they use the FOR XML AUTO to control the output.Does anyone know if I have to worry about this? I am tempted to let this slide and check out this part of the application after the migration happens tomorrow for QA to start testing.Yes I have been googling, checking my books and digging around in BOL. I am not seeing anything.DISREGARD: I found my derived table. It appears to change the output of the XML. Perfect.

I'm new to using SSIS and have been reading and learning slowly how to use it. I'm trying to create an identical copy of our database for reporting. I've used the Import/Export wizard, but have had some issues with foreign keys and with sql_variant columns.
I've tried searching for anything but haven't had any luck as of yet. I guess I don't even know where to start or what to look for.
Any help would be appreciated. Thanks!
how to auto increament fieldname id which is set as a primary key in sqlserver 2005 inasp.net2.0
View 1 Replies View RelatedI am using sql server 2000 and want to know how to get xml out of the database that looks like this using for xml auto
<Clients> <Client ID="1"> <Employer="Company1" /> <Employer="Company2" /> <Contact type="phone"> <contact type="email" value="test@test.com"> <contact type="phone" value="555-5555"> </Client> <Client ID="2"> <Employer="Company3" /> <Employer="Company4" /> <Contact type="phone"> <contact type="email" value="test@test.com"> <contact type="phone" value="555-5555"> </Client></Clients>
The problem I am having is that Contact is nested inside employer when I select Employer before Contact and the opposite happens when I select Contact first. They both join to the Client table so I would assume they both should nest directly under Client. How do I get different fields to nest directly under the same element like above?

Hi all,
I would like to have my SQL statement result to return an additional "column", automatically adding an "auto-increasing" number with it.
So if I for example select all Dates older than today's date, I would want something like this:
1
10/12/2006
2
10/18/2006
3
10/20/2006
4
10/22/2006
5
10/30/2006
Keep in mind that it's not my intention to fysically insert the "counting" column into the table, but rather do it "virtually".
Is this possible? And if yes, how ? :)
Thanks in advance
Nick

It's been a long time since I've had to check an index for the highest value, then add 1, to create a new unique key. These past few years, it seems this is usually done for you. But now that I'm working with MS-SQL, I don't see it. Is it there? It's doesn't seem to be inherent in the definition.
