INDEXIES – Inserting Of Large Amount Of Records

Feb 25, 2007

Is there any way how to create indexies after insertion of any
number of records (I dont want to create index after insertion of every record,
but for example after insertion of 1000 records) ?



 I heard it should be possible with „bulk insert“ or with
transactions. Is it right ? I need do this with MS SQL Server 2005 (Workgroup
edition).



 Thank you for your ideas!

Passing Large Amount Of Records As Single Parameter?

Jan 18, 2008

Hello all - I currently have a project that has a gridview on the front end. The user can select multiple items from this grid, hit a button and all of the selected records should be updated in the process. However, this resultset can have a large amount of data coming back, and I'm stumped on how to pass all of the ID's to the sp. I'd rather not call the SP for each record selected, as there could be 1,000 items selected, and well, I'd rather not call the SP 1000 times :p. I thought of generating a comma delimited list as I'm looping through the grid and using dynamic sql, but the IDs are about 6-7 numbers long, and including comma, would take up almost all of the max space in a varchar.
 Are there any good solutions to this problem? Passing the items as an array? Generating a data table in .NET and passing that?
 Any help would be appreciated.

Deleting Large Amount Of Data From The Table......

May 18, 2001

I need to delete data from a particular table which has more than half a million records. The data needs to be deleted is more than 200,000 records from the table. What is the best way to delete the data from the table other than importing into a temporary table and performing the same operation?

Let me know if the strategy to be followed is okay.

1. Drop all the triggers
2. Drop all the indexes
3. Write a procedure with a loop setting ROWCOUNT to 1000 and delete the records. ( since if I try to delete all the rows it will give timeout error )
The above procedure will delete 1000 records for each batch inside the loop till it wipes out all the data for the specified condition.
4. Recreate Indexes and Triggers.

Please let me know if there are any other optimal solution.

Thanx,
Zombie

Populating An Access Combo Box With Large Amount Of Data Causes Table Lock In SQL Server

Jul 20, 2005

I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)

How To Work With Huge Amount Of Records In A Table Using MSSQL Server 2000?

Dec 21, 2005

In
one of our forth coming projects, with ASP.Net/C#/MSSQL Server, We have
to deal with a Business table having about 15 millions of records. We
want to know, that which methodologies should we adopt, both regarding
front end and back end perspective, so the site could give optimised
performance. Also in place of a Dedicated Server, the Hosting Company
provides MSDE (that come with .net). Will this create any problem with
this project, that have such a huge table? Should we go for some
advanced database technique, such as, Clustering, Spliting Tables, etc.

Followings are the fields that the business table contains:

ID, Category ID (which comes from a Category table, each business is
under a category), BusinessName, SignupDate, Address1, Address2, Phone
Number,
Hours Of Operation, Years in Business, LicenseNumber, DiscountCoupon, Website

Large Amount Of Text?

Feb 22, 1999

We have created a databse in SQL Server 7 for support issues.
We are having trouble with only one aspect of the databse and that is the body of the supported problem.

The databse is basically a Question/Answer Support database whch house Frequently Asked Questions.
When the user does a search on a specific problem they have a list of matching questions shows on the screen (links).
When the question is clicked on it shows the Questions with the Answer of possible fixes.

Our problem lies in the fact that SQL server is truncating the Answer portion. I have tried different Data Types with maximum lengths with no success it keeps truncating it.
Right now I am on Data Type nvarchar with a length of 4000.

If anyone has any pointers on how to solve this problem all input is appreciated. You can post here to the forum or e-mail me directly at jason@flnet.com

Thank You.

Count Distinct In Large Table With 30M Records?

Jul 7, 2015

I have a task to count distinct records in a big table with roughly 30M records, performance is an important factor. Query is to be written to calculate weekly stats, weekly record number could be as high as 1M.

The actual result is like:
ID Policy
350235744Credit Cards
350235744PCI
350235744PCI Audit

So the final number for this particular Policy is 3

I can write the query like:

select count(distinct Incident_id) policy_name
from Reporting_DailyDlpDetail
Where (year(INSERT_DETECT_TS)=2015) and (month(INSERT_DETECT_TS) =6) and (day(INSERT_DETECT_TS) between 2 and 9)
This returns 526254 and costs 11 seconds to complete

or a query like:
Select distinct Incident_id, policy_name
from Reporting_DailyDlpDetail
Where (year(INSERT_DETECT_TS)=2015) and (month(INSERT_DETECT_TS) =6) and (day(INSERT_DETECT_TS) between 2 and 9)
This returns 749687 and costs roughly 1 minute to complete.

Result is different from the two queries, I believe the later gives correct number. How can I count the distinct based on a combo?Considering the size of data, what is the best and most efficient way to run the stats calculation against over 30 different scenarios (different policies and alert types) and not timeout?

How Do You Improve SQL Performance Over Large Amount Of Data?

Jul 23, 2005

Hi,I am using SQL 2000 and has a table that contains more than 2 millionrows of data (and growing). Right now, I have encountered 2 problems:1) Sometimes, when I try to query against this table, I would get sqlcommand time out. Hence, I did more testing with Query Analyser and tofind out that the same queries would not always take about the sametime to be executed. Could anyone please tell me what would affect thespeed of the query and what is the most important thing among all thefactors? (I could think of the opened connections, server'sCPU/Memory...)2) I am not sure if 2 million rows is considered a lot or not, however,it start to take 5~10 seconds for me to finish some simple queries. Iam wondering what is the best practices to handle this amount of datawhile having a decent performance?Thank you,Charlie Chang[Charlies224@hotmail.com]

How To Make Recursive Algorithm Without Using Large Amount Of Resources

May 4, 2015

How can I make a recursive algorithm in TSQL without using a large amount of resources?

New hires are put on a 6 month probation period, Their probation ends at the 6 month mark + sick time isnull(floor(sick_hours/8),0) they accrued during that 6 months. Their accrued sick days are added to the 6 month probation period to establish a new probation end date.

I then have to do the following loop:

1)Determine if any of the days between the original probation end date and the new probation end date have any weekend days or holidays for a particular employee.

2)If it does, I add those days to the new probation end date to create a newer probation end date.
a.I then go back up to step 1).

3)If it does not, I jump out of loop and look at the next employee on probation.

Note: I already have coding for determining number of sick days accumulated during an employee’s probation period. Recursive CTE? Recursive function? Other?

Does A Large Amount 'image' Data Affect Overall SQL Performance?

Jul 20, 2007

Recently we added a new table into our SQL2000 database specifically to store scanned in images of documents. This new table contains a PK field, a couple of datetime fields, a couple of char(1) fields and one 'image' field.



Before adding this table, the database size was approx 6GB. Six months after adding this new table, the database has grown to 18GB - 11GB of this is due to the scanned in images.



Would this new table affect the SQL performance with regards to accessing other data in the database that has nothing related to the new table?



If so, would moving this new table into it's own database be recommended?



Thanks

Large Amount Of Text Pushing To Separate Page After PDF Render

May 25, 2006

I am having a small problem.

When I generate a report with a large amount of text data (Paragraphs) the report will not split the text between two pages.

It will move the entire text box to the next page leaving a large amount of space on the previous page.

I tried every control on the page to render this. I tried textboxes, tables, lists, rectangles, subreports, etc..

The data is stored in a SQL table using a text data type (there can be a large amount of data entered into these database.

Any help on this would be great. I like reporting services, but there are just a few bugs.

I am using Reporting Services 2000 with Service Pack 2 and Hotfix

http://support.microsoft.com/?kbid=912424 (That fixed a different PDF rendering issue) and this problem was occuring prior to this hotfix.

Thanks in advance

SQL Server 2012 :: How To Quickly Update / Insert 3M Records In Large Table

Mar 28, 2015

Our system runs a SQL Server 2012 DB, it has a table (table_a) which has over 10M records. Our system have to receive data file from previous system daily which contains approximate 3M updated or new records for table_a. My job is to update table_a with the new data.

The initial solution is:

1 Create a table (table_b) which structur is as the same as table_a

2 Use BCP to import updated records into table_b

3 Remove outdated data in table_a:
delete from table_a inner join table_b on table_a.key_fileds = table_b.key_fields

4 Append updated or new data into table_a:
insert into table_a select * from table_b

As the test result, this solution is very inefficient. Step 3 costs several hours, e.g. How can I improve it?

Group / Union Statement - Pull Unique Records From A Large Table

Sep 22, 2014

I am trying to use SQL to pull unique records from a large table. The table consists of people with in and out dates. Some people have duplicate entries with the same IN and OUT dates, others have duplicate IN dates but sometimes are missing an OUT date, and some don’t have an IN date but have an OUT date.

What I need to do is pull a report of all Unique Names with Unique IN and OUT dates (and not pull duplicate IN and OUT dates based on the Name).

I have tried 2 statements:

#1:
SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#))
GROUP BY tblTable1.Name, tblTable1.INDate
ORDER BY tblTable1.Name;

#2:
SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#))
UNION SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#));

Both of these work great… until I the OUT date. Once it starts to pull the outdate, it also pulls all those who have a duplicate IN date but the OUT date is missing.

Example:

NameINOUT
John Smith1/1/20141/2/2014
John Smith1/1/2014(blank)

I am very new to SQL and I am pretty sure I am missing something very simple… Is there a statement that can filter to ensure no duplicates appear on the query?

When trying to link to an SQL table in Access 2003, the software appears to be malfunctioning. 

The sequence of events is File - Get External Data - Link Tables - Files of Type: ODBC Databases().

The Problem: On two of my computers, the select data source window does not pop up, preventing me from linking to any ODBC data source. 

Observations:  This function has worked normally in the recent past and works on other computers running Access 2003.  One difference between the computers working and non-working computers is Norton Antivirus 2006 (recent upgrade).

Has anyone experienced anything like this?  What's going on?

Inserting Large Number Of Records

Jun 20, 2006

Hi!

The DB I am working with has about 10 tables and some of the tables have 200,000 to 500,000 records. All tables have a clustered index on the primary key.

I performance during INSERT could be better I think - I add thousands of records at a time from many connections.

Is there a way to defer the update of indicies? So that, I can update the tables and then let the indicies regenerate ?

thanks,

Jas.
