Transact SQL :: Clone Some Rows On Selection
Apr 20, 2015
I have a table in which I have defined 2 columns. First column is called 'name' and second is called 'number'.It looks like sample bellow:
Name | Number |
---------------------------------
John | 2 |
Jessica | 3 |
Jack | 2 |
etc...
I need to make a query that will have the following results:
Name |
----------
John |
John |
Jessica |
Jessica |
Jessica |
Jack |
Jack |
John for 2 rows, Jessica for three rows and Jack for two rows. Is it possible only with loops or is there in SQL a duplicate/clone function...?

I need to query a table in Database 1 then, using a primary key, pull the columns from a table in Database 2.
The query I'm using in db_1 works:
SELECT * FROM db_1.table_1 WHERE (hcpcs_cd = '20552' AND srvc_units_num>'1 ' AND claim_dos_yr >'2012')
But what I really need are the columns associated with these records in db_2.table_1. There is a primary key in both tables.
Ultimately what I need is all of the columns in db_2.table_1 and the hcpcs_cd, srvc_untis_num, and claim_dos_yr from db_1.table1

I'm trying to run something like this:
Select ID, FIRST(forename), FIRST(surname) from table1
GROUP BY ID;
I know First doesn't work in TSQL, I used to use it in Access and now need to run something like that in TSQL. Simply getting unique ID with first forename and surname, cause there are some dupes in a table.
There are records like:
ID forename surname
--------------------------------
1 John Kormack
1 James Dope
2 Erin Dupes
3 Will Hugh
3 Walter Heisenberg
So I want to pull out:
1 John Kormack
2 Erin Dupes
3 Will Hugh
How can I run it in TSQL?

Howdy,
Is the any easy way to clone a database programatically?
I've searched the web but did not come up with anything.
At the moment I create a new blank database (based on the model database)
and create tables, indexes, etc. via asp. (The databases are always exactly
the same)
It seems to me that it would be a better option to
create one database with tables, indexes, etc and copy
it to a new database (on the same server).
One of the options I'm considering would be to create a database,
fill it with tables and indexes, etc. and then detach it.
Whenever I need a new database all I would have to do is use the
file system object to copy and rename the mdf file and then reattach the
new mdf file.
I realise that I could also make the changes to the model
database so that all new databases have the same structure
but that would be my last resort.
Is there any easier way to do this? A stored procedure perhaps?
You're opinions and advice would be welcomed.

How do I go about creating a cloned copy of an existing database on the same server? I basically want to set up a test copy of a production database, but let it reside on the same server with a slightly different name, prefixed with 'Testing_".
I typically just use Studio Express Manager and not scripts to do admin tasks. Here's what I tried that didn't work so well:
* Had full backups of production db
* Detached production database I wanted to clone
* From within Win Explorer, copy the .mdf and .ldf files within same data folder and gave them a new name, prefixing with "Testing_"
* Re-attached prodution db
* Attached "Testing_..." database
Sql Express seems confused at this point with new database I attached. It references the full path of the database I copied from (c:program filesmicrosoft sql servermssql.1data...". I rename the datbase, removing full path and prefixing with "Testing_".
* Using Sql authentication, changed the default database for the Login account to the new cloned copy of database.
* Did some query level data sanitizing to the cloned copy of the db. I am positive I performed this on the correct db.
* Was able to connect/authenticate to the cloned copy through a custom VB app on my dev machine, and all looked well.
* Tried to connect to the cloned db from another machine and couldn't. Went back to my dev machine and noticed the original production db looked hosed -- there were no tree nodes available to it! Was still able to connect to the cloned "Testing_" db copy, but not able to connect/authenticate anymore to the production copy.
* Detached cloned copy of "Testing_" db and moved it out of the data folder.
* Detached production db. Got an error msg indicating operation failure of some kind, but the database was gone from the tree.
* Reattached the production db but couldn't hit it from my custom vb app. Re-did the login and user accounts used by the app and was able to hit it. However, the data sanitizing I had done earlier in the cloned copy clearly was visibile in the production db!
* Had to restore production db from backup. Had problems authenticating from app, and recreated User account before the app was to connect.
Q1: What I am doing wrong? Sql Express was obviously as confused as me somewhere along the line.
Q2: Is specifying a default database used by a Login account necessary for a VB app like mine. I think it was something I discovered in the past, however, this would seemingly present a problem whenever I want my app to hit a different database, established through a connection string.
TIA...

HiI was in the situation of cloning a SQL server database last night.Today, a dependent application was behaving a little erratically thoughmost things were fine after sorting out some ntfs permissions. I'verecovered this database from backup exec before from a hot-backup, thisis the first time I've attempted this procedure though.Could I check with the experts here as to whether what I did was OK?Been googling to see if it is really the right thing to do, haven'tcome up with anything definitive...Assume server SOURCE and DEST:install DEST to same specification, OS, SQL patch level as SOURCE. Samepaths where applicable.shut down SQL server on bothCopy all datafile folder (d:sqldata) which is the full databaseincluding MASTER etc all over to DEST.Shut SOURCE down.Rename DEST to SOURCE, disable SQL server starting, set networksettings to those of SOURCE and reboot.Wait for things to settle after reboot and name change, bring SQLdatabase up.Client application now connects, I can't see any problems, but therehave been some strange anomalies in satellite applications today. Allhave been bounced to see if it's just a change they needed to notice,to no avail.Was that an OK operation to have done, or is there something just aboutto bite me when I'm not looking?Be grateful for any advice, I spent today pulling a lot of hair out.Thanks in advance :)AW

Not sure if there is anyway to do hots on sql server .From all I haveheard an EMC can do clones and fractures in order to implement a hotbackup or some kind of it in sql server.Seemingly the DBA has to do something toenable the fracture of the clone . Is anyone familiar with this ?Your input is highly appreciatedMB

I have a table "t_prod_cat" which contains hierarchical data which is used in production to present data.
CREATE TABLE [dbo].[t_prod_cat](
[cat_node_id] [bigint] IDENTITY(1,1) NOT NULL,
[advertiser_id] [bigint] NOT NULL,
[cat_hid] [hierarchyid] NULL,
[level] AS ([cat_hid].[GetLevel]()) PERSISTED,
CONSTRAINT [PK_t_prod_cat] PRIMARY KEY CLUSTERED
(
[cat_node_id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
In order not to impact the production website during the time an advertiser is editing (the editing might take much time and also mainly because at any time during the editing, the advertiser could cancel all the changes he did), I was thinking of transferring all the data linked to that advertiser to another table and let the advertiser apply any modifications up to the moment he will commit the changes.
Therefore, I would like to "CLONE" the hierarchy related to a certain advertiser_id to another table "t_prod_cat_work"
CREATE TABLE [dbo].[t_prod_cat_work](
[temp_cat_node_id] [bigint] NOT NULL,
[temp_cat_hid] [hierarchyid] NOT NULL,
[advertiser_id] [bigint] NOT NULL
) ON [PRIMARY]
What can be the easiest way to clone all the hierarchical data (multi-levels) from 't_prod_cat' to 't_prod_cat_work' for a certain advertiser_id ?

I have this requirement where some store procedures from a "seed" database need to be replicated to another database (on demand, so replication is not suppose to be use in this scenario).
I know it can be achieved by exporting the store procedures and then execute that at the B database but I want something a bit more automatic since it can be a large number of sprocs. I am trying something like this (still in dev):
SET NOCOUNT ON;
--
SELECT ROW_NUMBER() OVER(ORDER BY definition) seq, definition base
into #sprocs
FROM databaseA.[sys].[procedures] p
INNER JOIN databaseA.sys.sql_modules m ON p.object_id = m.object_id
[Code] ....
But I am sure there are way better ways to accomplish that...

Ive successfully cloned an SSRS VM Server within a scale out deployment to REPLACE a current physical machine. This wasn't too difficult.
The issue im having now is in creating a new SQL 2014 Environment with 3 SSRS nodes. Ive taken the time to build one up. Changed all my config files, installed all components etc & tweaks needed within my company...
I have now hit a brick wall though. Ive cloned this first server twice to give me 3 nodes. This is a new environment so the issue I have is that the rsreportserver.config files all now have the same InstallationID. I dont have any existing nodes to overwrite these files with. So when I attach the nodes to the database they will update the keys table with the same InstallationID as the first node and none will work.
Any way to force the SSRS setup to re-generate an installation ID - by repair maybe? Or is this something I can manually just make up?

I need limit on recursion. I have a recursion query. which gives me a parent child record set. I want my application to fetch only top 100 rows. In those 100 rows the parent child set should not get break. Even if it gives 105 rows also fine but it should have entire parent child structure.
If you see my below table. where null is the table which dont have parents but have the child.
ITEMID parentItemid
6 NULL
7 NULL
8 6
9 7
12 NULL
13 12
14 8
16 6
17 16
And it is temp table #test1and my recursive query.
;WITH Cte AS
(
SELECT ItemID,ParentItemID,CAST(ItemID AS VARCHAR(200)) [path] FROM #Test1 WHERE ParentItemID IS NULL
UNION ALL
SELECT t.ItemID,t.ParentItemID, CAST([path]+'.'+CAST(t.ItemID AS VARCHAR(20)) AS VARCHAR(200)) FROM Cte c JOIN #Test1 t ON C.ItemID=t.ParentItemID
)
SELECT * FROM Cte ORDER BY path ASC
Here how can i get top 100 parent child set.

I have one table list this
declare @test table(Id int, Description varchar(500))
insert into @test
values (1, '<b>Name :</b> XUZ <br/><br/>'),
(1, '<b>Type : </b> QWE <br /><br/>'),
(2, '<b>Name : </b> ABC <br /><br/>'),
(2, '<b>Type : </b> FGH <br /><br/>')
My expected result is
1, '<b>Name :</b> XUZ <br/><br/> <b>Type : </b> QWE <br /><br/>'
2, '<b>Name : </b> ABC <br /><br/> <b>Type : </b> FGH <br /><br/>'
As you can see its combine two rows of data group by id. Issue is If I use for xml path('') then its replace my html tags <b> to like <b> so after that then I again i need to replace all these symbols. Is it possible to get expected result without using xml path or if we use xml path then still my html tag leave as it is.

I would like to compare rows from 2 tables.
For ex:
Table1
Col1 Col2 Col3
1 a aa
2 b bb
Table2
Col1 Col2 Col3
1 a aa
2 b bb
Notice Table2.Col2 first row has an extra space " a", where Table1.Col2 value is "a".I need to compare all the columns, not just 1 column (any of the column can be different). Do we use CHECKSUM for this, or is there a better way to compare the 2 tables (in this case resulted in Table2 row 1 col 2 being the difference ?

The code works if the file is large but if its small 0 rows are affected. and also if i remove the header rows then the file works again. want to understand what is going on here. i am including the screen shot of the file in notepad++. I have tried changing the row terminator to ' ' , ' ' and also tried to change the codepage but nothing seems to work. No error file is being generated either, if i give a error file option.
