My boss asked me to interview 2 people on Monday for a programmer/developer position. They say they are gurus, but my boss wants me to find out for sure. I thought a question about bitwise operations would be good, maybe one about semi-joins. Are there any questions you can think of that will spot the phony pretty quick?
Thanks,
Jim
Is it possible to change table design without running an alter table SQL Script??
For example, change the following :
Table_A ( column1 int identity(1,1) <<----BEFORE
, column2 varchar(10) null
, column3 char(20) not null
)
to
Table_A ( column1 int identity(1,1) <<----AFTER
, column2 char(255) not null
, column3 varchar(20) null
)
Is it possible to change sysobjects and syscolumns or other system objects for this to occur??
I know this is not recommended but if I had to, what are the steps required to do this??
Thanks very much
I would like to create a command that will make a new logical field that is true or false depending on weather field is a certian value for example
col1,col2,col3
col1 is firstname
col2 is lastname
col3 is numeric
SELECT col1,col2,(if col3=6)=true AS Boolean
FROM table
i know this code doesnt work but it is a representation of what i would like to happen

I am trying to write a DTS package at work that uses a loop to fire a query off against a different server/database at each loop iteration. Prior to the execute SQL task , I use ActiveX (VBScript) to change the Catalog and DataSource of the connection (created by drag and drop if icon). My Execute SQL task selects @@servername and getdate() just as a dummy query to make sure I am actually pointed at a different server.
While testing the properties of the connection using global variables and msgbox shows that the database (catalog) and server (data source) ip address is being changed, the result returned is always from the first server. I feel like I need to disconnect the connection object, change the parameters and then reconnect to the new server but there doesn't appear to be anyway to do this.
Anyone out there able to successfully change a connection object inthis manner??
I got the following error on my database when I ran DBCC CHECKDB

Table error: Table 'PhoneCall' (ID 254623950). Missing or invalid key in index 'PhoneCall0' (ID 2) for the row:

Data row (1:98383:16) identified by (RID = (1:98383:16) ) has index values (PhoneCallID = 46361).
This error is on a couple of different indexii?? What do I do? Any help will be appreciated. Thank you
Ok guys I have read everything in my previous post but unfortunately can not seem to get it to work properly. Would anyone like to do this 10 minutes work (I am sure). Obviously I dont expect it to be free but if I continue I am going to get a sledge hammer to this now.
Thanks in advance
Hi,
I am trying to import comma delimitted text files which contain data for any particular country.
I have created SSIS package to import data into sql server table. table structure is exactly same as text file except one additional column which is to identify the CountryID. Text files we recieved does not contain CountryID column.
I am using BULK INSERT Task in SSIS to import the data as text files are quite big (up to 1 GB). during processing I do determine the country id for that text file as file name contain countrycode which can be use for lookup and get the countryid.
cyn_bills_20071208_032242.txt
CYN is the country code and country table has got country id for it.
I am using Format file with BULK INSERT task as table has additional column which does not present in source file.
currently after inserting all rows into table i have to run an UPDATE statement to update the value of CountryID column which is very expensive some time taking more then 30 min for (30 million rows)
Can anyone tell me how to insert an expression when using BULK INSERT command / Task in SSIS. there must be a way to insert litterals using Bulk Insert.
Thanks in Advance.

Good afternoon one and all,
I have the following problem :
I have a table which currently has 40+ mill records. Some of the fields are of type nvarchar and these need changing to varchar. I have attempted to change these fields to varchar but the process proceeds to increase the transaction log (to 6 Gigs!) until there is no space left on the server (causing a multitude of other problems with existing programs on the server). Once this happens I have no choice but to kill the change.
Does any1 know how I can make these changes without SQL writing to the transaction log?
Any and all help appreciated,
Thanks

Hello,
I am executing the bcp statement with i a stored procedure, everything works fine. But the question is I want to pass the delimiter as a parameter to the BCP command. I tried but i couldnt make it. I declare a variable and set that variable to a delimiter and try to pass that variable to BCP, but it doesnt accept it, in the export file the delimiter is '@i' instead of ';'
DECLARE
@i CHAR(2)
SELECT @i = ';'
EXEC master..xp_cmdshell 'bcp " select city, name = case whenname like(''%''+char(13)+char(10)+''%'') then replace(name, char(13)+char(10),'''') whenname like(''%''+char(13)+''%'') then replace(name, char(13),'''')whenname like(''%''+char(10)+''%'') then replace(name, char(10),'''')else name end From dbDev..tbtest" queryout d:invoice.txt -c -Sdevelop_server -Uadmin -Padmin -t@i'

This files occupies 2G.B of disk space... We are in the cleaning process to create some disk space. The thing is no one really understand which application uses this files..
My question is does sql server uses this files... Can we delete this files..
Thank you..

Does anyone know if there is an updated Books Online for 2000 published anywhere?? Or even a more recent copy of the 7.0? MS has probably made corrections
to them.
Also, I'm looking for all the free info about DTS for 2000. Not anything that MS publishes, more of a third party evaluation.
Thanks in advance,

I have a application that uses a connection that is always active until the application is closed, and many other connections that are opened and closed as different data is requested. I DO close and dispose these connections, datasets, and data readers after requesting data to release the resources. BUT they still show in SQL Server 2005 Express Edition. I believe they are NOT active and are part of the Pooling system.
The problem is the connections don't seem to be reused, the Pooling system just makes more, so I end up with hundreds of them until no more connections can be created but SQL Server; hence timing out on some attempt to open a connection.
I have experimented with the 'Min Pool Size' and 'Max Pool Size' values in the connection string but the only change is behavior is that I can make more connection showing in SQL Server but the problem still happens anyway.
I am rewriting this application from VB6 to VB.Net. The VB6 version uses SQL Server 2005 Edition too and the connection problem doesn't exist.
Any ideas would be appreciated.
This is an upgrade issue :
I have a SQL server 6.5 with NT users mapped into the SQL Server running in production. At one point of time, this Server was set up for mixed security, which has since been changed to standard ( still with NT users mapped in ).
When upgrading to SQL 7.0, I noticed that it brought in both : Nt USers as well as the mapped login id's as if they were separate entities ( Probably since SQL Server stores mapped login id's in master..syslogins, and mapped NT logins information are stored in the registry ). It also, does not bring in passwords.
I am planning to re-write this part of the upgrade and write my own scripts to transfer the logins ( Unfortunately, I will have to drop them first from the database using sp_dropuser, immediately after the upgrade process ).
Here's how I'm planning to do this : BCP out the contents of the syslogins table from the 6.5, bring it in into, say 'sys_xlogins' ( New table ) in 7.0, update the 'sysxlogins' system table in 7.0 with the passwords from the 'sys_xlogins' table, and add all the users back into the database.
If anyone else has been thru this, or anything like this ( Upgrading from mixed security 6.5 to 7.0 ), I would appreciate their inputs. Any words of wisdom / experience welcome !

Hello all,

Can someone prove this wrong?

Hello,
I've been trying to fill a tree view based on some criteria in another table.
I have the standard table with a ID - ParentID - Text
when I bind the table everything works fine.
What I need to do is display only the tree items based off a username and ID in another table.
Files can be found http://www.cthere.com/treeviewhelp.zip
EXAMPLE:
tblTourgroup(UserName = Jim)
tblTourgroup (GroupID = 110)
tblGroups (GroupID = 110)
Results from tblGroup:
- RESTAURANTS
- Cuisine
- Steakhouse
Query Results should be layed out like tblGroups
Any ideas?
This is what I have so far... But it does not traverse up and get the other nodes..
USE SQL2005_335573_cplanet;
GO
WITH DynamicTree (ParentID, GroupID, GroupName)
AS
(
SELECT e.ParentID, e.GroupID, e.GroupName
FROM tblGroups AS e
INNER JOIN tblTourGroup AS edh
ON e.GroupID = edh.GroupID
)
SELECT e.ParentID, e.GroupID, e.GroupName
FROM DynamicTree as e
INNER JOIN tblTourGroup AS dp
ON e.GroupID = dp.GroupID
WHERE dp.UserName = N'Test'
GO
Good fortune came my way this morning I was invited to an interview for a Database Administrator/IT Support position with a local charity.Although my 2 years experience with IT has been mainly supporting desktops Win 98,2K ,XP in a workgroup together with training users on MS Office Professional I decided to go for the database admin/IT support because I want to broaden my experience with IT applications. The objective being to become more marketable to employers.While I definately meet most of the IT support/training requirements for the post a few requirements are making me nervous because I have no experience in them since I believe I may need programming and or other skills which I don't have. The accountabilities that make me nervous are the following :
1. Devise and implement solutions to corrupted data and software inconsistencies or failures of the housing database.
2. Devise and implement solutiions to corrupted data and software inconsistences or failures of the management information system.
3. Devise and deliver reports from the housing database or MIS in order to satisfy the requirements of managers and external regulatory bodies.
4. Test and validate new versions of software.
Do I need database programming skills for these requirement?If not what skiils do I need and what would be the best way of answering quetions about these requiremnts during interview since I have no database admin experience ?
Looking forward to your thoughts on this.

Hello everybody,
I'm new to SQL Server,I have a interview tomor,could anybody give me a website from where i can get questions on SSRS.
Thanks in advance
As a developer, we always say "using a stored procedure, instead of a cliet side SQL statement, provides performance benefits". However, it seems it has not been true anymore since SQL Server 7.0.
See SQL online "Execution Plan Caching and Reuse" at http://msdn.microsoft.com/library/default.asp?url=/nhp/default.asp?contentid=28000409
I am quite confused with the following questions:
1. it seems since SQL 7.0, a SQL statement in client side uses the existing execution plan as a stored procedure does. That means SP doesn't has much advantage over SQL statement in terms of performance.
2. It seems, a stored procedure is not always compled ONLY once. If a stored procedure is not used for a long time, it could be kicked out from procedure cashe.
3. In order to use an existing execution plan, it seems that we have to use the fully qualified identifier, such as
SELECT * FROM Northwind.dbo.Employees
instead of
SELECT * FROM Employees
However, I rarely see anyone uses these kind of fully qualified references for objects both in SQL statements and SP. For example, in the sample database pubs and NorthWind, they don't use the fully qualified expression. I only see the use of it in master database.
I guess I might miss something in the issues above. I would like to get any explanation from SQL guru or anybody. Thanks a lot.
