Performance Gains When INSERTing Multiple Rows
Aug 11, 2006
I apologize since this seems to be a fundamental question, but I did try to search and there seems to be something wrong - after clicking on the "search" button, the page just will not update... I even tried "advanced search" but no luck there, either.
Anyway, my question is about writing multiple data rows to tables in a SQL Server database. Currently I'm using embedded SQL from a VC++ 2005 .Net program to write data to a SQL 2005 Express server (either on the same PC or on another, via TCP). As data becomes available, I issue INSERT statements, one by one. One row is about a dozen columns, typically 8 bytes each, for each of the few tables in the database. In most cases, I have several rows of data available at the same time. Those rows come at the rate of around 200-1000 per second for the different tables. With that setup, my SQL server is not able to keep up - the data ends up getting buffered in the program, waiting for the server, the server process uses just about all the CPU cycles it can get, etc.
I'm reading the "SQL in a nutshell" book from O'Reilly but it's mostly language oriented, it doesn't say much about performance improvements. It would seem natural that one could improve the performance. For example, when I do a SELECT query, the data comes very quickly, which makes me think that it is the overhead of making those individual calls with small amount of data. I would think that I should be able to request that multiple rows are written at the same time with a single SQL statement, and that this would improve the performance. However, I have no idea how to do that.
I did try one thing - enlisting the sequence of INSERTs into a single transaction, thinking it will all get buffered and only get written to the server after the Commit command is issued. I did that but it doesn't seem to help. What should I try to alleviate this problem? One thing to consider: although I use SQL Server for testing, I am trying to keep compatibility with other databases, e.g., ODBC to any available data source, including MS Access over Jet. I would love it if the solution to this were compatible (i.e., not involve any Transact SQL or other vendor-specific tricks).
I thank you in advance for your assistance!

I have a legacy prod db of 102Gb which contains 101Gb of free space. The db
comprises 2 Primary (.mdf's) on one drive and over 200 (.ndf's) residing on one logical drive, (4 physical drives with RAID 5). ie. Each user table object has its own (.ndf). Some of these tables have been allocated up to 15Gb.
Limited documentation suggests that performance benefits can be achieved by
allocating a maximum size to certain key tables rather than setting the table
properties to autogrow.
No mention is made of grouping these files into filegroups to potentially achieve the same performance gains.
Transportability of this db is now a problem since no other test/dev/prod boxes contain enough free space.
I propose to re-create the db and have the user data tables reside within the (.mdf) - possibly even group highly active tables within filegroups.
Are there any benchmark tests or KB articles to indicate/support the original
strategy of using multiple (.ndf's) over data tables within one (.mdf)??
Thanks, in advance.

Hi :I have a TableA with around 10 columns with varchar and numericdatatypesIt has 500 million records and its size is 999999999 KB. i believe itis kbi got this data after running sp_spaceused on it. The index_size wasalso pretty big in 6 digits.On looking at the tableAit didnot have any pks and hence no clustered index.It had other indicesIX_1 on ColAIX_2 on ColBIX_3 on ColCIX_4 on ColA, ColB and ColC put together.Queries performed in this table are very slow. I have been asked totune up this table.I know as much info as you.Data prior to 2004 can be archived into another table. I need to run aquery to find out how many records that is.I am thinking the following, but dont know if i am correct ?I need to add a new PK column (which will increase the size of thetableA) which will add a clustered index.Right now there are no clustered indices2. I would like help in understanding should i remove IX_1, IX_2, IX_3as they are all used in IX_4 anyway .3. I forget what the textbox is called on the index page. it is set to0 and can be set from 0 to 100. what would be a good value for it ?thank you.RS

Hi, would like to know if there are any links or sample code to learn how to Insert multiple rows with 1 sql statement.Also, can the inserted values' source be from a table in another database table or from a dataset?I am actually trying to insert about 117 rows of data.Table 1======UID Primary Key TeamCode a code value representing different teams Week will equal to 2Points nullable valuee.g.Table 1======UID TeamCode Week Points1 A1 1 1002 A2 1 99trying to insert into table 1Table 1========UID TeamCode Week Points1 A1 1 1002 A2 1 993 A1 2 null4 A2 2 nulletc...As you can see, UID is primary key, TeamCode may repeat according to week value Week is a constant Points will be nullHow can I do that with a single Insert Command? Thank you for your help. :)

Hi,
I am trying to insert 9 rows into an table at the same time. My situation is this...
I have a survey page. There are 9 parts with each part ment for an individual person. Each part has 8 questions, and each part has the same 8 questions
The questions are answered using one of the answers in a drop down box.
So when the surveyer clicks submit, all the 9 parts should be entered into the table.
If this is confusing, I have the form up on the Internet at...
http://www.lavenderlane.ie/wage_survey_test.asp
I can insert one part no problem, (when I reduce the form to only 1 part) but i need to insert all of the 9 parts simultaneously. I reckon its some sort of for loop but if u could help me out i would appreciate it!
Thanks a lot

Say for instance I got 2 tables
Subject Table and a Student Table
The Subject Table consist of the following attributes:
Subject_ID [PK], Subject_Name, Course_ID and Course_Name
The Student Table consists of the following attributes:
Subject ID [FK], Students_Name, Students_bday, Students_age, Students_height and Students_weight
How can I use the INSERT function when I would like to add a row with the following details:
Course_Name : Biotechnology
Students_Name : Fred
Students_bday : 01/JAN/1990
Stundets_age : 54
how to use the INSERT function for multiple tables.

Hi,
Is it possible to insert multiple rows in a table using one INSERT statment. If yes, how can I do that ? I tried doing this using the substitution method.
Using Substitution Method - This is how,I proceeded.
INSERT INTO EMP (EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO)
SELECT ‘&EMPN’, ‘&ENAM’, ‘&JO’, ‘&MG’, ‘&HI’, ‘&SA’, ‘&COMM’, ‘&DEPTN’ UNION ALL
SELECT ‘&EMPN’, ‘&ENAM’, ‘&JO’, ‘&MG’, ‘&HI’, ‘&SA’, ‘&COMM’, ‘&DEPTN’
Let me know if this is correct.
Thanks,
Vandana

Hi,I have an application running on a wireless device and being wireless Iwant it to use bandwidth as efficiently as possible. Therefore, I wantthe SQL statement that it uploads to the SQL Server to be as efficientas possible. In one instance, I give it four records to upload, whichcurrently I have as four seperate SQL statements seperated by a ";".However, all the INSERT INTO... information is the same each time, theonly that changes is the VALUES portion of each command. Also, I haveto have the name of each column to receive the data (believe it or not,these columns are only a small subset of the columns in the table).Here is my current SQL statement:INSERT INTO tblInvTransLog ( intType, strScreen, strMachine, strUser,dteDate, intSteelRecID, intReleaseReceiptID, strReleaseNo, intQty,dblDiameter, strGrade, HeatID, strHeatNum, strHeatCode, lngfkCompanyID)VALUES (1, 'Raw Material Receiving', '[MachineNo]', '[CurrentUser]','3/21/2005', 888, 779, '2', 5, 0.016, '1018', 18, '610T142', 'K8',520);INSERT INTO tblInvTransLog ( intType, strScreen, strMachine, strUser,dteDate, intSteelRecID, intReleaseReceiptID, strReleaseNo, intQty,dblDiameter, strGrade, HeatID, strHeatNum, strHeatCode, lngfkCompanyID)VALUES (1, 'Raw Material Receiving', '[MachineNo]', '[CurrentUser]','3/21/2005', 888, 779, '2', 9, 0.016, '1018', 30, '14841', 'B9', 344);Since the SQL statement INSERT INTO portion remains the same everytime, it would be good if I could have the INSERT INTO portion onlyonce and then any number of VALUES sections, something like this:INSERT INTO tblInvTransLog (intType, strScreen, strMachine, strUser,dteDate, intSteelRecID, intReleaseReceiptID, strReleaseNo, intQty,dblDiameter, strGrade, HeatID, strHeatNum, strHeatCode, lngfkCompanyID)VALUES (1, 'Raw Material Receiving', '[MachineNo]','[CurrentUser]', '3/21/2005', 888, 779, '2', 5, 0.016, '1018', 18,'610T142', 'K8', 520)VALUES (1, 'Raw Material Receiving', '[MachineNo]','[CurrentUser]', '3/21/2005', 888, 779, '2', 9, 0.016, '1018', 30,'14841', 'B9', 344);But this is not a valid SQL statement. But perhaps someone with a morecomprehensive knowledge of SQL knows of way. Maybe there is a way tostore a string at the header of the command then use the string name ineach seperate command(??)

I am trying to insert each record coming from my DataTable object to sql server database.

Hello all,my first post here...hope it goes well. I'm currently working onstored procedure where I translated some reporting language into T-SQLThe logic:I have a group of tables containing important values for calculation.I run various sum calculations on various fields in order to retrievecost calculations ...etc.1) There is a select statement which gathers all the "records" whichneed calculations.ex: select distinct Office from Offices where OfficeDesignation ='WE' or OfficeDesignation = 'BE...etc.As a result I get a list of lets say 5 offices which need to becalculated!2) A calculation select statement is then run on a loop for each ofthe returned 5 offices (@OfficeName cursor used here!) found above.Anexample can be like this(* note that @WriteOff is a variable storing the result):"select @WriteOff = sum(linecost * (-1))From Invtrans , InventoryWhere ( transtype in ('blah', 'blah' , 'blah' ) )and ( storeloc = @OfficeName )and ( Invtrans.linecost <= 0 )and ( Inventory.location = Invtrans.storeloc )and ( Inventory.itemnum = Invtrans.itemnum )"...etcThis sample statement returns a value and is passed to the variable@WriteOff (for each of the 5 offices mentioned in step 1). This is donearound 9 times for each loop! (9 calculations)3) At the end of each loop (or each office), we do an insert statementto a table in the database.

To anyone that is able to help....What I am trying to do is this. I have two tables (Orders, andOrderDetails), and my question is on the order details. I would liketo set up a stored procedure that essentially inserts in the orderstable the mail order, and then insert multiple orderdetails within thesame transaction. I also need to do this via SQL 2000. Right now ihave "x" amount of variables for all columns in my orders tables, andall Columns in my Order Details table. I.e. @OColumn1, @OColumn2,@OColumn3, @ODColumn1, @ODColumn2, etc... I would like to create astored procedure to insert into Orders, and have that call anotherstored procedure to insert all the Order details associated with thatorder. The only way I can think of doing it is for the program to passme a string of data per column for order details, and parse the stringvia T-SQL. I would like to get away from the String format, and gowith something else. If possible I would like the application tosubmit a single value per variable multiple times. If I do it this waythough it will be running the entire SP again, and again. Anysuggestions on the best way to solve this would be greatlyappreciated. If anyone can come up with a better way feel free. Myonly requirement is that it be done in SQL.Thank you

hi,
I came across the following topic which speaks about inserting multiple rows into a table.
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=52980
The following is the code it concludes:
----------------------------------------------------------
INSERT INTO InstitutionManagement.dbo.b10_partC
(unitid, repyear, test, subject_area, scores,
credit_awarded, comments, recno)
select
unitid = 'data1a',
repyear = 'data1b',
test = 'data1c',
subject_area = 'data1d',
scores = 'data1e',
credit_awarded = 'data1f',
comments = 'data1g',
recno = 'data1h'
union all
select
unitid = 'data2a',
repyear = 'data2b',
test = 'data2c',
subject_area = 'data2d',
scores = 'data2e',
credit_awarded = 'data2f',
comments = 'data2g',
recno = 'data2h'
union all
select
unitid = 'data3a',
repyear = 'data3b',
test = 'data3c',
subject_area = 'data3d',
scores = 'data3e',
credit_awarded = 'data3f',
comments = 'data3g',
recno = 'data3h'
... And so on...
----------------------------------------------------------
My question is based on the performance of the above insert statement aganist Microsoft.Net SqlBulkCopy Class.
One more thing: Does the above statement gets executed as asingle statement or as multiple statements (One execution for each Select statement).
thanks

Hello,
I have a survey (30 questions) application in a SQL server db. The application uses several relational tables. The results are arranged so that each answer is on a seperate row:
user1 answer1user1 answer2user1 answer3user2 answer1user2 answer2user2 answer3
For statistical analysis I need to transfer the results to an Excel spreadsheet (for later use in SPSS). In the spreadsheet I need the results to appear so that each user will be on a single row with all of that user's answers on that single row (A column for each answer):
user1 answer1 answer2 answer3user2 answer1 answer2 answer3
How can this be done? How can all answers of a user appear on a single row
Thanx,Danny.

I have an item table (#Codes) which contains itemIDs, some of which are always used in a subsequent data table (#Data) to hold information about a case+scearnio. These item rows have a standarditem value = 1. Rows in the item table which may be included in the subsequent data table (#Data), but not for every single case+scearnio, are considered nonstandard rows and therefore have a standarditem value = 0. I have been trying to write some code that automatically inserts rows from #Codes which have standarditem = 1 into #Data for each of the caseID+scenarioIDs in #Cases but have not figured it out yet. See "desired result" below to see exactly the output I'm trying to achieve.
Also, is there a way to insert the standarditem = 1 rows from #Codes into #Data when new caseID+scenarioID rows are added to #Cases? Ultimately, I'd like to either create a button for the user to click in the Access interface that inserts these rows when clicked OR when the user enters a new caseID+scenarioID in #Cases the rows just automatically appear for the new case row. This way, the rows will already have the caseID, scenarioID & itemID fields already populated and all the user will have to do is enter the item value and be able to manually add standarditem = 0 rows and their values if needed.

Does anybody have a sample SQL script that will select table A and compare it to table B. If a row exists in both table A and table B, it will update the columns in table B with the columns in table A. If the row does not exist in table B, it will insert a row in table B using the row in table A. Is this possible?
Thanks Mitch

I am in the process of creating a Report, and in this, i need ONLY the row groups (Parents and Child).I have a Parent group field called "Dept", and its corresponding field is MacID.I cannot create a child group or Column group (because that's not what i want).I am then inserting rows below MacID, and then i toggle the other rows to MacID and MacID to Dept.

I concatenate multiple rows from one table in multiple columns like this:
--Create Table
CREATE TABLE [Person].[Person_1](
[BusinessEntityID] [int] NOT NULL,
[PersonType] [nchar](2) NOT NULL,
[FirstName] [varchar](100) NOT NULL,
CONSTRAINT [PK_Person_BusinessEntityID_1] PRIMARY KEY CLUSTERED
[Code] ....
This works very well, but I want to concatenate more rows with different [PersonType]-Values in different columns and I don't like the overhead, of using the same table in every subquery ([Person_1]). Is there a more elegant way to do this, without using a temp table or something else?

Hello All,
I am rather new to reporting on SQL Server 2005 so please be patient with me.
I need to create a report that will generate system information for a server, the issue im having is that the table I am having to gather the information from seems to only allow me to pull off data from only one row.
For example,. Each row contains a different system part (I.e. RAM) this would be represented by an identifier (1), but I to list each system part as a column in a report
The table (System Info) looks like:-
ID | System part |
1 | RAM
2 | Disk Drive
10| CPU
11| CD ROM |
Which
So basically I need it to look like this.
Name | IP | RAM | Disk Drive|
----------------------------------------------
A | 127.0.0.1 | 512MB | Floppy
So Far my SQL code looks like this for 1 item
SELECT SYSTEM PART
FROM System Info
WHERE System.ID = 1
How would I go about displaying the other system parts as columns with info
Any help is much appreciated!

Why does this code tell me that I inserted 2 rows when I really only inserted one? I am using SQL server 2005 Express. I can open up the table and there is only one record in it. Dim InsertSQL As String = "INSERT INTO dbCG_Disposition ( BouleID, UserName, CG_PFLocation ) VALUES ( @BouleID, @UserName, @CG_PFLocation )"Dim Status As Label = lblStatus
Dim ConnectionString As String = WebConfigurationManager.ConnectionStrings("HTALNBulk").ConnectionString
Dim con As New SqlConnection(ConnectionString)
Dim cmd As New SqlCommand(InsertSQL, con)
cmd.Parameters.AddWithValue("BouleID", BouleID)
cmd.Parameters.AddWithValue("UserName", UserID)
cmd.Parameters.AddWithValue("CG_PFLocation", CG_PFLocation)
Dim added As Integer = 0
Try
con.Open()
added = cmd.ExecuteNonQuery()
Status.Text &= added.ToString() & " records inserted into CG Process Flow Inventory, Located in Boule_Storage."
Catch ex As Exception
Status.Text &= "Error adding to inventory. "
Status.Text &= ex.Message.ToString()
Finally
con.Close()
End Try Anyone have any ideas? Thanks

Hi,
I have a DataTable in memory and I want to write a C# code to dump the data into a SQL database. Is there a faster way of dumping millions of rows into a SQL table besides running INSERT INTO row by row?
Thank you,
