Will A Single Row Be Locked Or The Entire Table?

Feb 19, 2006

I am giving the following statement outside the begin tran block in a stored procedure:
select * from table1 with (holdlock) where column1 = @colValue
I have the following two questions regarding above situation:

Being outside the begin tran block, will the select statement cause a lock to be held or it has to be within the begin tran block for the lock to be held?
Will the select statement hold a lock only on the row or rows matching the where clause, or it may lock a page or even the entire table in this situation?
Thanks

Move Entire SQL Server Instance

Jan 29, 2007

I have tried searching all over and have not been able to find what I need, but this is what I have pieced together.

Background:
I need to move an entire instance of SQL Server 2000 SP3 running on Windows Server 2000 to a new physical server running SQL Server 2000 SP4 running on Windows Server 2003. I guess my biggest question is how do I move system databases (master,msdb,tempdb,model), I don't particularly like the idea of using sp_detach/sp_attach on system databases?

This is what I had in mind.
-Install SP4 on the source server
-Backup source to tape
-Restore from tape to destination server (restore system dbs as re_master,re_msdb)
-Shut SQL services down on destination server.
-Replace the system dbs .mdf and .ldf with the re_master & re_msdb .mdf and .ldf
-Restart SQL services
-Restore User databases from tape.

Ultimately, I'm asking can you change the undlying .mdf & .ldf files for system databases?

Also, are there any issues going from Windows Server 2000 to Windows Server 2003?

Thanks in advance.

Transact SQL :: Avoid Same Table Multiple Times Rather Than Put Records In Single Table And Use It Throughout

Nov 19, 2015

There are 3 tables Property , PropertyExternalReference , PropertyAssesmentValuation which are common for 60 business rule

SELECT  
 PE.PropertyExternalReferenceValue  [BAReferenceNumber]
, PA.DescriptionCode
    [PSDCode]
, PV.ValuationEffectiveDate
    [EffectiveDate]
, PV.PropertyListAlterationDate
    [ListAlterationDate]

[code]....

Can we push the data for the above query in a physical table and create index to make the query fast rather than using the same set  tables multiple times

How To Move A Single Database From SQL Server Instance To New SQL Instance

Jan 13, 2007

Hi,

I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do ..

Thanks in advance..

Regards,

Transact SQL :: Pull All Records From One Table And Just A Single Record From Another

Aug 7, 2015

I'm trying to pull all records from one table and just a single record from another.  I have this join, (see below).  It works ok, but the problem is if a blog record doesn't have a corresponding image record it doesn't return.  The end result should be the blog record and a single corresponding image record.  But always a blog record.

SELECT
[Blogs].[ID],
[Blogs].[BlogTitle],
[Blogs].[BlogType],
[Blogs].[BlogText],

Single Instance/Multiple Instance/Virtualization Q

May 17, 2007

I work for a mid size company with the usual collection of enterprise applications. We are trying to consolidate our SQL environment consisting of around 100 databases none of which are over 100GB with the average database size around 5GB. Recently a large server was purchased as the "Big Daddy" SQL box. Obviously not all the databases will be moved to this one box but within reason a number can.

My question: What is the best way to configure the box?

1 OS & 1 Default Instance - How do we isolate loops memory leaks etc...
1 OS & Multiple instances, ie:Dedicated instance for each application. - How do you allocate CPU & memory, allow for optimum performance without putting others at risk from a rouge process?
Virtualized OS for each application with a default instance - Too much overhead impacts performance?

Future plans include offsite replication, perhaps mirroring with failover.

I'd appreciate anyone else's thoughts ideas? How have you tackled this problem in your environment?

Thanks
Scott

Transact SQL :: How To Update Multiple Rows In Different Transactions In A Single Table

Jul 16, 2015

We have control table which will be useful whether we need to start the job or not. If we are starting the Job we will make it to 1.

Below is the Table Structure.

Table Name       IN_USE_FG
CUST_D                     0
PROD_D                     0
GEO_D                       0
DATE_D                     0

Now we have different packages for 4 tables data loading. These 4 packages will start at a time. Before going to load the data we have to make the Flag to 1 and after that we have to load it. Because of this we have written Update statement to update the Value to 1 in respective Package. 

Now we are getting dead lock because we are using same table at a same time. Because we are updating different records.

Transact SQL :: How To Update New Table By Separating Single Date Column

Oct 11, 2013

I am trying to build a DIM table using a source table that has the following setup...

CREATE TABLE [dbo].[APPL_STATUSES](
[APPLICATIONS_ID] [varchar](10) NOT NULL,
[POS] [decimal](10, 0) NOT NULL,
[APPL_STATUS] [varchar](5) NULL,
[APPL_STATUS_DATE] [datetime] NULL,

CREATE TABLE [dbo].[APPL_APPLICANT_STATUSES](
[APPLICATIONS_ID] [varchar](10) NOT NULL,
[POS] [decimal](10, 0) NOT NULL,

Transact SQL :: Table Valued Function Returns Nothing When Single Column Selected

Apr 21, 2015

We run std 2008 r2.  I haven't looked at my friend's function closely yet bur he showed me that when he selects from the function with one column and the same where clause he uses on same func with select *, he gets no data under the column he requested. 

But when he selects * he gets a single row.

I took a peek and see a bunch of left joins followed by a bunch of outer applies in his func. I suppose (thinking out load) if anything random like the order of rows returned or sql decisions on how query runs can affect his function, that might explain it.

Transact SQL :: Convert Entire Scheduling Functionality For A Report

Oct 19, 2015

In our application, we do scheduling.   I need to convert the entire scheduling functionality into Transact-SQL for a report.  I'm stumped on how to convert some of that functionality.  We use a function from Delphi that I see no equivalent in SQL.  Further, we still support SQL2005, so the Transact-sql has to be compatible with SQL2005.  So, DateFromParts will not work at all for me as it was added in a later version.

The function looks like this:function EncodeDayOfWeekInMonth(const AYear, AMonth, ANthDayOfWeek, ADayOfWeek: Word): DateTime;

The purpose of the function is:Returns a DateTime that represents a specified occurrence of a day of the week within a specified month and year.how I can do this with a Transact-sql statement?  As I said earlier, I'm constrained by the fact it must work in a SQL2005 instance.

Transact SQL :: Find Missing Months In A Table For The Earliest And Latest Start Dates Per ID Number?

Aug 27, 2015

I need to find the missing months in a table for the earliest and latest start dates per ID_No.  As an example:

create table #InputTable (ID_No int ,OccurMonth datetime)
insert into #InputTable (ID_No,OccurMonth) 
select 10, '2007-11-01' Union all
select 10, '2007-12-01' Union all
select 10, '2008-01-01' Union all
select 20, '2009-01-01' Union all
select 20, '2009-02-01' Union all
select 20, '2009-04-01' Union all
select 30, '2010-05-01' Union all
select 30, '2010-08-01' Union all
select 30, '2010-09-01' Union all
select 40, '2008-03-01'

For the above table, the answer should be:

ID_No OccurMonth
----- ----------
20 2009-02-01
30 2010-06-01
30 2010-07-01

1) don't include an ID column,

2) don't use the start date/end dates in the data or

3) use cursors, which are forbidden in my environment.

Transact SQL :: Find Unmatching Columns Between Two Tables While Applying A Change Column Prefix Table

Nov 16, 2015

For our ETL process, we maintain a TransformationList table that has the source view and the destination table. Data is copied from the view into the table (INSERT INTO). I am trying to find column names in the Views that are not column names in the associated Table.

In the below example, want to end up with three records:

 1, View1, Column4
 2, View2, Column4
 2, View2, Column5

I have it almost working, except that there is a table, ChangeColPrefix table, that is used by the ETL process to change some of the view's column name prefixes. Some of the source views have column names with prefixes that do not match the destination table column names. Say view SouthBase has all the column names prefixed with SB - like SBAcct, SBName. And the Destination table of Area District has ADAcct, ADName. There would be a row in the ChangeColPrefix for SouthBase, SB, AD, 1, 2 that would be used by the ETL process to create the INSERT INTO Area District From SouthBase.

I need to use this ChangeColPreifx to find my unmatching columns between my source views and destination tables. With out that table SBAcct and SBName from SouthBase will not appear to match the columns of ADAcct and ADName, but they do match.

I want to end up with these three records as non-matching:

View1, Column4
View2, Column4
View2, Column5

View1 has Salumn2 and View2 has Salumn5, and they must be changed to Column2 and Column5 as per the ChangeColPrefix table before running the Select from INFORMATION_SCHEMA.COLUMNS EXCEPT Select from INFORMATION_SCHEMA.COLUMNS looking for unmatched columns.

/***** Set Up Test Data *****/
-- Create 2 test views
IF EXISTS(SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[View1]'))
DROP VIEW dbo.[View1]
GO
CREATE VIEW View1
AS SELECT '1' AS Column1 , '2' AS Salumn2 , '4' AS Column4;

[Code] ....

I need to apply a hotfix (Cumulative Update 6 for SP1) to just one instance. Can I do this by failing over the affected instance to one of the passive nodes, applying the hotfix, and failing it back again or do I need to apply the hotfix to all nodes as detailed in:
