DB Engine :: How To Point Linked Server To Specific Database / Rename Linked Server

Apr 24, 2015

I am using Linked Server in SQL Server 2008R2 connecting to a couple of Linked Servers.

I was able to connect Linked Servers, but I cannot point to a specific database in a Linked Server, also, I cannot rename Linked Server's name.

How to point the linked server to a specific database? How to rename the Linked Server?

The following is the code that I am using right now:

USE [master]
GO
EXEC master.dbo.sp_addlinkedserver
    @server = N'Machine123Instance456',
    @srvproduct=N'SQL Server' ;
GO
EXEC sp_addlinkedsrvlogin 'Machine123Instance456', 'false', NULL, 'username', 'password'

T-SQL (SS2K8) :: Arrival And Depart Location Query

Apr 7, 2014

I have a question regarding the selection of arrival and departure city.

CREATE TABLE #XY123
(
tktamt MONEY,
departcty VARCHAR(5),
arrivalcty VARCHAR(5),
tktnum INT

[Code] ....

There are One way, Round trips and journey with connecting flights in the above data, what I am looking for a report is tktamt, deprt city, arrival city and tktnum in a single line for each trip.

SO if it is one way trip or round trip there is no issue, if it is a trip with connecting flights tktnum has more than four records. In the above case for tktnum 34567 there are four records, for which I have to display only one record, where the depart city is 'JFK and Arrival city is 'SFO' as well as amount and tktnum.

SQL 2012 :: Minimize Migration Downtime On Large DB?

Apr 20, 2015

I'm preparing a checklist for myself before getting ready to migrate from 2005 to 2012. Our largest database is a nice one at over 250GB. I'm thinking my best bet to minimize any downtime would be to Restore the DB (NORECOVERY) on the new server and keep rolling it forward with the transactional logs. Eventually I'll need to bring the old DB offline and do one last backup and apply that one to the new server but that should be a small time frame given the whole process could take several hours.

Reporting Services :: Exporting Fixed Columns From SSRS For Use In Mainframe Data File

Jun 3, 2015

I need to be able to export a data file as flat file (.txt) with fixed columns for use by Mainframe.

I will be uploaded this file using the Windows File Share Option

Render Format does not have .txt, but does have a data feed option. So I will try that.

But, I do not see an option for fixed column width.

Transact SQL :: Populate Column On Insert Based On Value From Another Table

Jul 26, 2015

I have the following 2 tables:

Table: classes  Columns: classID, hp
Table: char_active  Columns: name, classID, hp

The classes table is already populated.

What I want to do is insert a new row into char_active using the name and classID column, and have the HP column auto populate based on the corresponding value in the classes table. This is the trigger I wrote but I'm getting the error

Incorrect syntax near 'inserted'.

I'm new to sql, this is actually the first trigger I've tried writing. 

create trigger new_hp on curr_chars.char_active
instead of insert
as
declare @hp tinyint
select @hp=lists.classes.hp from lists.classes where lists.classes.classID=inserted.classID
insert into curr_chars.char_active (name, classID, hp) inserted.name, inserted.classID, @hp
go

Server Query Execution - Where Filtration Order - Performance Impact

Jul 27, 2015

For example in a Select Statement we have many tables and we have Where Clause with many conditions with AND operations. Do the SQL SERVER would apply the Where clause after all fetch or can dynamically decide about to include the related Tables from Select Statement Orderly with respect to where clause predicates? (SQL SERVER would not fetch data of those tables for its Select, where the AND condition in Where clause fails or by logic would be fruitless/not-related.)

T-SQL (SS2K8) :: Multiple Contact / Possibilities - How To Remove Duplicates

Aug 11, 2015

I have a bunch of contacts that I've scored how well their names match to other contacts in the same business. I can programmatically figure out how to parse the results, but would like to know how to do this via SQL. My problem is for Business_fk 968976 I have 7 contacts. In the end I should have 4 contacts based on name match. For the business key listed Gerardo Lopez is in the ContactScore table twice for Contact keys 7355719 and 57028145. I then have two rows like so:

PossibleBusinessContactMatch_pk BusinessContact_fk Business_fk BusinessContactMatch_fk MatchTypeCode MatchScore MatchRank FirstName LastName Phone Email
------------------------------- ------------------ ----------- ----------------------- ------------- ----------- ----------- -------------------------------------------------- -------------------------------------------------- ---------- --------------------------------------------------------------------------------------------------------------------------------
1772960 57028145 968976 7355719 C 46 1 GERARDO I LOPEZ 8162214000
838834 7355719 968976 57028145 C 50 1 GERARDO

Each reference each other, and 2 is a good case, a more difficult case would have key 1 listed 10 times showing a ContactMatch_fk of 2 - 11, and then Contact_fk 2 listed 10 times with a ContactMatch_fk of 1, 3-11.I know 57028145 maps to 7355719 from the first row in the ContactScore table, so when Contact_fk of 7355719 comes up I should be able to skip it and not process that match. Hopefully that makes sense. Anyway here is the test data:

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[ContactScore]') AND type in (N'U'))
DROP TABLE [dbo].[ContactScore];
GO
CREATE TABLE [dbo].[ContactScore]
(
[ContactScore_pk]INT NOT NULL,
[Contact_fk]INT NOT NULL,

[code]..
