Insert Into Indexed Table

Jul 20, 2005

Hi I have a huge table with over 100million records and on regular
basis ineed to delete nearly a million records and insert a million
records.
Currently I delete indexes before going through the process and
recreate the indexes which takes a very very long time.
IS there a way to disable indexes and re enable them after doing
insert and delete by reindexing or anything of that sort?
OR
Is there an approach to append two tables with similar indexes?

Please air you opinior, will mean a lot to me.
Thnaks

Transact SQL :: Returning Non Indexed Records From Sorted Table - Speed Same As Indexed?

Dec 1, 2015

I have created a table from another table where I specified that one of the fields, an number field,  is sorted in ascending order and have NOT specified that it is to be an indexed field and there are 10 million records, from 1 to 10,000,000 exactly.

Now, if I query that table, asking to return records 1-1,000 from that non indexed number field that I sorted in ascending order (where number field <= 1,000) , will it run as fast as if it were indexed?

In other words, does SQL know somehow that these records are sorted in ascending order and so will not do a full table scan, stopping at 1,000 to return my data set?

Or is there no way for SQL to know this and only specifying an indexed field allows SQL to know that its in some order and so it doesn't have to do the full scan?

Truncate On An Indexed Table

Apr 1, 2008

Hi All,

I had a situation today where I needed to truncate a table. It has an index on it.
When I truncate it directly, it takes hardly a minute but when I drop the existing index on that table and then truncate, it takes ages. I am not able to comprehend the exact reason. Can anybody explain?

Thanks in advance.

SOS - Table Partitions Or Indexed Views.

Feb 26, 2008

Hi Experts,

We have a very huge database that stores 12 years of data(120 Million records). But our application mainly accesses past 3 years data i.e , the queries would scan the 120 million records even when it actually has to scan 30 million records alone (for 3 years).

Since few other important applications needs access to all the 12 years data, we are in a position to have 12 years data in the same database.

Right now we are looking for an approach that would help us to efficiently access the 3 years data alone and boost the performance.

1. Will SQL server table paritioning help in this scenario ?

Or

2. Indexed views would help us ? Is it possible to create indexed views based on year range and access the views in the stored procedures ?

Any help would be greatly appreciated.

Thanks in advance,

Hariarul

SQL Server 2012 :: Query To Search Full-text Indexed Table And Return Results

Apr 19, 2014

I have written this sample query to search a full-text indexed table and return the results. If the word occurs more than once I want it to return as a new record and the results show a short summary of the location. I was using 'like', but the full table scans were really slowing it down. Can performance be improved for the following (The results returned by my query are accurate)

Query

DECLARE @searchString nvarchar(255);
DECLARE @searchStringWild nvarchar(275);

SET @searchString = 'first';
SET @searchStringWild = UPPER('"' +@searchString+ '*"');

SELECT id, '...' + SUBSTRING(searchResults.MatchedCell, searchResults.StartPosition, searchResults.EndPosition - searchResults.StartPosition) + '...' as Result

T-SQL (SS2K8) :: Stored Procedure To Truncate And Insert Values In Table 1 And Update And Insert Values In Table 2

Apr 30, 2015

table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt

process:
1. get data from an existing view and insert in temptable
2. truncate/delete contents of table1
3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted)
4. insert data in table2 which are not yet present (comparing ID in t2 and temptable)
5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)

* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.

Strange Problem: SQL Insert Statement Does Not Insert All The Fields Into Table From Asp.net C# Webpage

Apr 21, 2008

An insert statement was not inserting all the data into a table. Found it very strange as the other fields in the row were inserted. I ran SQL profiler and found that sql statement had all the fields in the insert statement but some of the fields were not inserted. Below is the sql statement which is created dyanmically by a asp.net C# class. The columns which are not inserted are 'totaltax' and 'totalamount' ...while the 'shipto_name' etc...were inserted.there were not errors thrown. The sql from the code cannot be shown here as it is dynamically built referencing C# class files.It works fine on another test database which uses the same dlls. The only difference i found was the difference in date formats..@totalamount=1625.62,@totaltax=125.62are not inserted into the database.Below is the statement copied from SQL profiler.exec sp_executesql N'INSERT INTO salesorder(billto_city, billto_country, billto_line1, billto_line2, billto_name,billto_postalcode, billto_stateorprovince, billto_telephone, contactid, CreatedOn, customerid, customeridtype,DeletionStateCode, discountamount, discountpercentage, ModifiedOn, name, ordernumber,pricelevelid, salesorderId, shipto_city, shipto_country,shipto_line1, shipto_line2, shipto_name, shipto_postalcode, shipto_stateorprovince,shipto_telephone, StateCode, submitdate, totalamount,totallineitemamount, totaltax ) VALUES(@billto_city, @billto_country, @billto_line1, @billto_line2,@billto_name, @billto_postalcode, @billto_stateorprovince, @billto_telephone, @contactid, @CreatedOn, @customerid,@customeridtype, @DeletionStateCode, @discountamount,@discountpercentage, @ModifiedOn, @name, @ordernumber, @pricelevelid, @salesorderId,@shipto_city, @shipto_country, @shipto_line1, @shipto_line2,@shipto_name, @shipto_postalcode, @shipto_stateorprovince, @shipto_telephone,@StateCode, @submitdate, @totalamount, @totallineitemamount, @totaltax)',N'@billto_city nvarchar(8),@billto_country nvarchar(13),@billto_line1 nvarchar(3),@billto_line2 nvarchar(4),@billto_name nvarchar(15),@billto_postalcode nvarchar(5),@billto_stateorprovince nvarchar(8),@billto_telephone nvarchar(3),@contactid uniqueidentifier,@CreatedOn datetime,@customerid uniqueidentifier,@customeridtype int,@DeletionStateCode int,@discountamount decimal(1,0),@discountpercentage decimal(1,0),@ModifiedOn datetime,@name nvarchar(33),@ordernumber nvarchar(18),@pricelevelid uniqueidentifier,@salesorderId uniqueidentifier,@shipto_city nvarchar(8),@shipto_country nvarchar(13),@shipto_line1 nvarchar(3),@shipto_line2 nvarchar(4),@shipto_name nvarchar(15),@shipto_postalcode nvarchar(5),@shipto_stateorprovince nvarchar(8),@shipto_telephone nvarchar(3),@StateCode int,@submitdate datetime,@totalamount decimal(6,2),@totallineitemamount decimal(6,2),@totaltax decimal(5,2)',@billto_city=N'New York',@billto_country=N'United States',@billto_line1=N'454',@billto_line2=N'Road',@billto_name=N'Hillary Clinton',@billto_postalcode=N'10001',@billto_stateorprovince=N'New York',@billto_telephone=N'124',@contactid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@CreatedOn=''2008-04-18 13:37:12:013'',@customerid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@customeridtype=2,@DeletionStateCode=0,@discountamount=0,@discountpercentage=0,@ModifiedOn=''2008-04-18 13:37:12:013'',@name=N'E-Commerce Order (Before billing)',@ordernumber=N'BRKV-CC-OKRW5764YS',@pricelevelid='B74DB28B-AA8F-DC11-B289-000423B63B71',@salesorderId='9CD0E11A-5A6D-4584-BC3E-4292EBA6ED24',@shipto_city=N'New York',@shipto_country=N'United States',@shipto_line1=N'454',@shipto_line2=N'Road',@shipto_name=N'Hillary Clinton',@shipto_postalcode=N'10001',@shipto_stateorprovince=N'New York',@shipto_telephone=N'124',@StateCode=0,@submitdate=''2008-04-18 14:37:10:140'',@totalamount=1625.62,@totallineitemamount=1500.00,@totaltax=125.62

Default Table Owner Using CREATE TABLE, INSERT, SELECT && DROP TABLE

Nov 21, 2006

For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.

Insert To Recordset Gives Different Date Format To Table Insert ????????

Jun 28, 2007

Help please!



I have an asp page with some simple vbscript to add a record to a table, the record has a datefield (dob).

the insert results in a US formated date if I add a record to a dynamic recordset but a UK formated date if I insert direct to the table ?????

i.e.

if request("dob") is "01/11/2007" (1st november 2007)





set conn = server.createobject("adodb.connection")

set rs = server.createobject("adodb.recordset")

rs.open "tez", mc, 2, 2 rs.addnew

rs("dob") = request("dob")

rs.update



11 jan 2007 stored in table



while



set trs = Server.CreateObject("ADODB.RecordSet")

qfn= "insert tez values('"+request("dob")+"')"

trs.Open qfn,mc



results in

1 november 2007 is written to the table.

Both of these methods are used in the same asp page.



This is on a windows2003 server, sql2005,iisv6, asp.netv2



I have tried every setting I can find in iis,asp,sql server to no avail.

I need the recordset method to work correctly.

SQL Server 2008 :: Insert Data Into Table Variable But Need To Insert 1 Or 2 Rows Depending On Data

Feb 26, 2015

I am writing a query to return some production data. Basically i need to insert either 1 or 2 rows into a Table variable based on a decision as to does the production part make 1 or 2 items ( The Raw data does not allow for this it comes from a look up in my database)

I can retrieve all the source data i need easily but when i come to insert it into the table variable i need to insert 1 record if its a single part or 2 records if its a twin part. I know could use a cursor but im sure there has to be an easier way !

Below is the code i have at the moment

declare @startdate as datetime
declare @enddate as datetime
declare @Line as Integer
DECLARE @count INT

set @startdate = '2015-01-01'
set @enddate = '2015-01-31'

Hello,
I'm currently performance tuning a table with 100 million rows in it
(about 18 GB of data) and would like to know if -

1. Is the table too large to be performance tuned. Is it better to just
redesign the schema ?
2. Can using techniques as indexed views really help me with tuning such a table.
3. How long would it take to create a clustered, non clustered index on
a varchar column (for instance) on a table with 100 million rows ?
(i know this is a function of hardware as well - let's assume i'm using
afairly maxed out DL 360 - i.e. dual processor with 4 GB of memory)

Thank you very much

I am looking for a little insight. I am using an SQL Server database created by a third party vendor. There are certain columns in a given table that I query for quite often. To speed things up, I created an indexed view.

Now I can no longer insert into the base table. Attempting an insert causes a SQL error stating that the system properties ARITHABORT and NUMERIC_ROUNDABORT are incorrect. If I remove the index from my view, the inserts work just fine.

Can somebody provide some insight as to why this happens and how I might be able to correct it (keep in mind that the DB was setup by a third party, so I cannot change too much of the underlying setup without possibly compromising their functionality).

Indexed Views

Hi,

I am trying to create an indexed view, but because I am using a MAX function, I get the error

Cannot create index on view "dbo.View" because it uses aggregate "MAX". Consider eliminating the aggregate, not indexing the view, or using alternate aggregates. For example, for AVG substitute SUM and COUNT_BIG, or for COUNT, substitute COUNT_BIG.

Am totally stuck on how I can replace the MAX function.

Any help would be appreciated.

Regarding Indexed Views

Aug 6, 2007

Dear experts,
I've been working for an ERP solutions, company, as a DBA....

we have around 1200 tables as wellas 650 views.....

we are not using clustered index on views.....
using the clustered index will boost the performance? and the ERP is web based application. so that modifications will be done on a regular basis....
is it good thing to implement clustered indexes on these views....

please guide me in this regard


thank you verymuch
