View 4 Replies View RelatedTesting Strategies For SSIS?
Aug 23, 2007I have been somewhat dismayed by the lack of information available relative to testing SSIS solutions. At a time when both managed code and db code are getting tooling (through VSTS) to help drive an automated testing mentality into developers everywhere - there seems to be little out there for those using SSIS. I have seen people talk about having SSIS packages that test the actual packages - there is always the manual way to write the tests in something like C# and then programmatically invoke the package and manually validate the results. Anyone out there have approaches that are working for them?

Backup Strategies For Hosted Enviroment ?
Oct 2, 2007Im about to start a project that will be hosted by a third party web host. What is a common way to backup your database and have the backup saved ? The data may end up being several 100 MB of user settings, text etc (blog type stuff). If the DB gets to be several 100MB, then does making a backup and ftping it offsite sound reasonable ? Does ftp bandwidth usually count against your overall bandwidth usage ?
View 2 Replies View RelatedSQL 2012 :: Queue Table Strategies
Jul 10, 2015I'm trying to flesh out a good queue table design with our dev team.So here is a general overview of the scenario. First an application will hit a WebAPI and grab any updates to Content and store those ID's in SQL (queue table). Next is the fun part, different multi threaded apps will process ID's from the queue. One app will make updates to the data in a different SQL DB while the other will update an index (likely Elastic).
Obviously, we don't want multiple threads working on the same items. One strategy could be to use UPDLOCK & READPAST query hints. However, I'm not sure about the reliability or performance of this solution. I just started looking into setting up a service broker but that would be completely unfamiliar territory for me. Also I can see how a broker might work well within the instance but how would that work with the application making updates to Elastic?

Oct 28, 2014I have the requirement to implement archiving of some database old data.
The database is not used to store files, just table with text/numeric data, some data modification logs.
Which strategies do you usually use to archive old records from a database?
Do you move old/unused data to another similar database in another server?
The data needs to be accessible for read access, even when archived.
Available Strategies To Upgrade A Database Schema Without Downtime
Mar 29, 2007There is a great book on database refactoring that contains a comprehensive set or recipies on how to revise databases that are supposed to be always online and may have various clients that can't be upgraded at the same time. I guess this is a typical case with large databases and I would be surpised if Amazon stops their servers just to move a column from one table to another. The book describes necessary steps for such changes. Basically it's all about creating intermediate database schemas that would be used during transition period.
For example, if we need to move a column from one table to another:
Version 1.
Table A columns: Name, Price
Table B columns: Quantity, Date
Let's say we move Price to table B:
Version 2.
Table A columns: Name
Table B columns: Quantity, Date, Price
The book suggests an intermediate version:
Version 1_2.
Table A columns: Name, Price
Table B columns: Quantity, Date, Price
Additional trigger that will synchronize "Price" columns between A and B.
Version 1_2 can be used by both clients written for version 1 and 2. Software developers don't need to rush their upgrades, transition can last months and include several changes.
This technique requires accuracy in version control management, but looks very good to implement non-interruptible database schema upgrade. I wonder if this is the only option available for data schema upgrade with no downtime. I can't think about anything else - it this how large data warehouses updata their databases?
Online Re-indexing Vs Offline Re-indexing
Sep 10, 2007Hi,
The other day we tried online re-indexing feature of SQL 2005 and it€™s performing faster than offline re-indexing. Could you please validate if it€™s supposed to do be this way? I always thought offline should be faster than online.

Indexing
Jul 18, 2005Hi!! I dont know if this is the correct forum for this or not, but still...Actually i wanted to know some details about SQl's Indexing services.
I found this link on my hosters help pages :
You need to use SQL Query Analyzer tool for this.
This will enable full-text indexing for the current database:exec sp_fulltext_database 'enable'
This creates a catalog:exec sp_fulltext_catalog 'catalogname', 'create'
This enables indexing of a table:exec sp_fulltext_table 'tablename', 'create','catalogname', 'indexname'
This adds a column to an index:exec sp_fulltext_column 'tablename', 'columnname', 'add'
This activates fulltext on a table:exec sp_fulltext_table 'tablename', 'activate'
These two enable automatic filling of the full-text index when changes occur to a table:exec sp_fulltext_table 'tablename','start_change_tracking'exec sp_fulltext_table 'tablename','start_background_updateindex'
From the above i get that i need to set up my database for indexing then make a catalog and then add an index of a table to this catalog. Can anyone point any good tutorials for using this is the proper way so that performance is not affected and tells me details on updating indexes etc(esp using some criterias). Moreover does indexing columns lower the performance? Is there a workaround? I am completely new to this.
Re-Indexing
Jun 13, 2002What should I be looking at if I have real-time data (constant transactions) writing to a table that is experiencing index type problems? The table needs to constantly be re-indexed, which is slowing the whole transaction process down.
What can I look at or do to rectify this?
Thanks!

Mar 13, 2008Hi,
Can you please help me find out if this statement is always true:
"Adding a new Index slows down updates"
This is more a general question, applicable as well for SQL Server.
If this is not the appropriate subforum then I kindly ask an moderator to move this thread to the appropriate sub-forum.
Thank you,

Indexing Help
May 25, 2007Okay, so i've been creating a .net app that basically gathers data from a web page, and then passes the parameters to a s.p. i wrote in sql, fetches a count, and displays the data to the webpage. My problem layes in that i have the query command timeout set to 1:00 but alot of my quries on the larger tables take longer then that to complete, so the page is timing out quite often.
i KNOW my problem is database design, i'm running an OLAP database. trasactions only occur once a week when we run a federal DO_NOT_CALL database update. i was wondering if anyone would be so kind as to help me tune my database a little more the get some more juice out of it. i can also tell you guys that i've notice every time a query is ran, the Diqk Query length tacs out to nearlly 100% for the entire length of the query. dont know if that helps.

Nov 19, 2007Hi evryone...
I have a problem on indexing. The field PK_hrSetBenefitsLeave is the primary key of the table "hrSetBenefitsLeave". When i see it on the "Manage Indexes and Keys", the identity name became PK_hrSetBenefitsLeave_1. Everytime i change it to its original name will get me error...and i can't save it.
Error msg on saving :

- Unable to create index 'PK_hrSetBenefitsLeave'.
There is already an object named 'PK_hrSetBenefitsLeave' in the database.
Could not create constraint. See previous errors.
I tried to check using this query.
Select * from Information_Schema.Columns where column_name = 'PK_hrSetBenefitsLeave'
- it gives me only 1 record

Mar 21, 2007Hi,
There is a table which I regularly run a select query on.
The select query always has a fixed where clause on only three of the columns with different parameters.
This is a query that runs each time:
select * from tblData
where
PersonNo = 2 and EmployeeType = 4 and DataDate = getdate()
This are the types of indexes the table currently has:
One index for each of these three fields
i.e. index1 for PersonNo
index2 for EmployeeType
index3 for DataDate
In addition to the above, I also have created a covering index as follows
index4 for PersonNo,EmployeeType,DataDate
Is what I have enough for indexes on this table please?
Is there anything else I have to do on indexing this table?
Thanks
Where Can I Go For Help With MS Indexing Services?

Jan 2, 2008If you put an index on an integer type column named 'test_column' in a table that had 1,000,000,000 rows in it, and you said select top 50 * from test_table WHERE test_column = 1 since 'test_column' has an index, that would perform extremly fast wouldn't it? Cheers
View 5 Replies View RelatedRe-indexing In Parallel
Apr 25, 2001Hi All,
I am working on SQL Server 7.0. Every weekend we go for reindexing of some tables. I want to know if it is possible to run the re-indexing of tables in parallel so that I can save time.
Our database is of size 80GB and one table is around 22GB. Rebuilding of index on this table takes a lot of time and we are unable to index the other tables.
Any solutions/suggestions are mostly appreciated.

SQL Indexing - ***BASIC****
Sep 15, 2005Hoping someone could me with an ongoing indexing question that I have.
On my site, we have over the past 5 years developed what is emerging as a fairly complicated dbase structure, as features have been added to my site and relations have increased between different database tables, there has been a need to index fields in different ways, and in some instances field indexing has overlapped. For example we may have a table that has 5 fields (field1,field2,field3,field4,field5). A need to index field1 is requried because of a query that reads:
SELECT * From Table1 where field1=XXXXX
Additionally there may be a need to for another query that reads:
SELECT * From Table1 where field2=XXXXX
In this instance an index is placed on field2....
But, for example when there is the following query:
SELECT * From Table1 where field1=XXXXX and field2 = XXXXX
Is it necessary to set a new index on: field1,field2 ???
We have made the choice that yes, in fact there is...but now over time some of our tables have instances of single fields being indexed along with combinations of two single fields that have already been indexed, being indexed together. As tables have grown to over 1,000,000 records and having up to 15 or so indexes, we realize that the number of indexes maybe degrading performance. Also, indexes vary in type, e.g INT,BIGINT,Varchar fields... In the above instance, can we eliminate the multi-indexes and improve performance over all...?
On a second related question:
In the event that two tables are joined on a common field.
e.g. Select * from Table1,Table2 where Table1.field1=Table2.field1
Is it necessary to index both of these fields in tables: Table1 and Table2 ?
Hope someone can help, as we are looking to improve the efficiency of our tables as they continue to grow.
Indexing Is Not Helping
Mar 25, 1999I have a database with no index on any table,
I have to pull out records from them, process them and insert into a
set of table in another database. There is no one to one mapping. What
I have been doing is get the data into cursor and manipulate row by row
and insert to target tables. This is very slow even for few thousand
records and we have to do it for few hundred thousands.
The process takes long time to run (hours for 20000 records). I created indexes to speed up the
operation, but with index my process just hangs, I have put some print
statements within the transaction loop that also does not appear on
ISQL, it appears only after I kill the process.
It's all confusing to me, index is not helping at all. I checked the
query plan for queries after creating index, it displays fine but the
stored procedure just stops.
Indexing And Duplicates
Aug 5, 2002Hi,
I’m using SQL Server 2000. I have a table called Contacts and I would like to be able to have the UserID as an indexed column and to ignore duplicates. I set up the following properties within my SQL Server database table:
Table Name: Contacts
Selected Index: IX_UserID
Column Name: UserID
Order: Ascending
Create Unique
Index
Ignore Duplicate Key
Every time I try to enter duplicates for the UserID column; I get an error that says, “Cannot enter duplicate key row in object ‘Contacts’. Can anyone explain this? Is it possible to create an index column with duplicate data?
Thanks,
Denise
SQL Indexing Question
Aug 26, 2005Folks,
I am not really sure how the whole indexing side of MS SQL works (I'm a noob), so my question has 2 parts:
1) Does SQL store every Index in memory?
2) If so, can I perform a SELECT on a table's index(s) without hitting the disk?
For example: I have a table with a column called "Id" which is of type uniqueidentifier. I want to select all of the "Id"s in the table without accessing the server's hard drive (get info from memory).
Thanks in advance!

Indexing Suggestions
Jun 29, 2006I'm looking for some help on how i should index this table.
current table has about 500k records in it.
the fields in the table are:
member_num (varchar(12), not null)
first_name (varchar(20), null)
last_name (varchar(20), null)
ssn (varchar(50), null)
address1 (nvarchar(200), null)
address2 (nvarchar(200), null)
city (nvarchar(200), null)
state (nvarchar(200), null)
zip (nvarchar(100), null)
phone1 (nvarchar(50), null)
all of the fields are searchable through an asp.net webform.
my first stab at this consisted of creating a clustered index on member_num and then creating a separate index for each of the remaining fields.

Jun 12, 2008Dear All,
in my current databases, indexing is very poor. same columns are having clustered index and non clustered indexes. is there any tool to help me out?
i'm thinking in this way...please correct me if i'm thinking wrong...
1) i'm planning to drop all the indexes first.
2) i'm planning to create clustered index on ID column.
3) i'm planning to create non clustered index on some columns which are using where conditions.(many procedures and functions, as well as report queries).
4)planning to run the index rebuild script everday at non-peak time
5)planning to run the index defragmentation script every week at non-peak time
6) planning to run shrink database command every week.
please correct me and add flavour with your great experience.
thank you very much

Indexing Issues

and per1_age>=20
and wealth_rating>=1
and hm_purprice>=100 --6 sec / 3 sec
AND oo_mtg_amnt >= 100
and est_inc >= 'B'
and per1_ms='M'
and hm_year_build>='1905'
and oo_mtg_lender_name<>' '
and oo_mtg_rate_t in ('f','v')
and oo_mtg_loan_t in ('c','f')
and hm_purdate>='20000101'
and child_pres='y'
and zip in (85302,85029)
and state_abbrv in ('az')
and rtrim(city)+' '+state_abbrv in ('glendale az','phoenix az')
and rtrim(county_name)+' '+state_abbrv in ('maricopa az')
and substring(phone,1,3) in ('602','623')
group by o.state_abbrv ORDER BY o.state_abbrv
i'm trying to fine tune the database to come back with quries in less then 30 seconds. EVERY query ran will be a count.
i've managed to fine tune it to the point where anything above the rtrim(city) comes back in about 3-7 seconds. my problem is everything below that. i cant seem to get a query to respond fast enough, any recommendations? i've tried pluging the whole query into the index tuning wizard and it gives me nothing.
