Problem Inserting Rows After Table Creation
Dec 29, 2004
I am using the below SQL to insert a table. The problem is after I run this, I run another script to populate the table (see below). The population script will work if I run it as INSERT INTO ... SELECT TOP 99.9999999 PERCENT ..., but if I put 100 PERCENT, or just use no percent limiter I get the following error: Msg 8624, Internal SQL Server error.
It is weird b/c once something is inserted in the table, i can run the populate script without any problems. Any idea as to why this is happening?
Thanks,
Dave

I have a SQL script to insert data into a table as below:
INSERT into [SRV1INS2].BB.dbo.Agents2
select * from [SRV2INS14].DD.dbo.Agents
I just want to set a Trigger on Agents2 Table, which could delete all rows in the table , before carry out any Insert operation using above statement.I had below Table Trigger on [SRV1INS2].BB.dbo.Agents2 Table as below: But it did not perform what I intend to do.

Hi,
I'm working on a database for a financial client and part of what i need to do is calculate a value from two separate rows in the same table and insert the result in the same table as a new row. I have a way of doing so but i consider it to be extremely inelegant and i'm hoping there's a better way of doing it. A description of the existing database schema (which i have control over) will help in explaining the problem:
Table Name: metrics_ladder
id security_id metric_id value
1 3 80 125.45
2 3 81 548.45
3 3 82 145.14
4 3 83 123.32
6 4 80 453.75
7 4 81 234.23
8 4 82 675.42
.
.
.
Table Name: metric_details
id metric_id metric_type_id metric_name
1 80 2 Fiscal Enterprise Value Historic Year 1
2 81 2 Fiscal Enterprise Value Current Fiscal Year
3 82 2 Fiscal Enterprise value Forward Fiscal year 1
4 83 2 Fiscal Enterprise Value Forward Fiscal Year 2
5 101 3 Calendar Enterprise value Historic Year 1
6 102 3 Calendar Enterprise Value Current Fiscal Year
5 103 3 Calendar Enterprise value Forward Year 1
6 104 3 Calendar Enterprise Value Forward Year 2
Table Name: metric_type_details
id metric_type_id metric_type_name
1 1 Raw
2 2 Fiscal
3 3 Calendar
4 4 Calculated
The problem scenario is the following: Because a certain number of the securities have a fiscal year end that is different to the calendar end in addition to having fiscal data (such as fiscal enterprise value and fiscal earnings etc...) for each security i also need to store calendarised data. What this means is that if security with security_id = 3 has a fiscal year end of October then using rows with ids = 1, 2, 3 and 4 from the metrics_ladder table i need to calculate metrics with metric_id = 83, 84, 85 and 86 (as described in the metric_details table) and insert the following 4 new records into metrics_ladder:
id security_id metric_id value
1 3 101 <calculated value>
2 3 102 <calculated value>
3 3 103 <calculated value>
4 3 104 <calculated value>
Metric with metric_id = 101 (Calendar Enterprise value Historic Year 1) will be calculated by taking 10/12 of the value for metric_id 80 plus 2/12 of the value for metric_id 81.
Similarly, metric_id 102 will be equal to 10/12 of the value for metric_id 81 plus 2/12 of the value for metric_id 82,
metric_id 103 will be equal to 10/12 of the value for metric_id 82 plus 2/12 of the value for metric_id 83 and finally
metric_id 104 will be NULL (determined by business requirements as there is no data for forward year 3 to use).
As i could think of no better way of doing this (and hence the reason for this thread) I am currently achieving this by pivoting the relevant data from the metrics_ladder so that the required data for each security is in one row, storing the result in a new column then unpivoting again to store the result in the metrics_ladder table. So the above data in nmetrics_ladder becomes:
security_id 80 81 82 83 101 102
----------- -- -- -- -- -- --
3 125.45 548.45 145.14 123.32 <calculated value> <calculated value>
4 ...
.
.
.
which is then unpivoted.
The SQL that achieves this is more or less as follows:
*********
START SQL
*********
declare @calendar_averages table (security_id int, [101] decimal(38,19), [102] decimal(38,19), [103] decimal(38,19), [104] decimal(38,19),etc...)
-- Dummy year variable to make it easier to use MONTH() function
-- to convert 3 letter month to number. i.e. JAN -> 1, DEC -> 12 etc...
DECLARE @DUMMY_YEAR VARCHAR(4)
SET @DUMMY_YEAR = 1900;
with temp(security_id, metric_id, value)
as
(
select ml.security_id, ml.metric_id, ml.value
from metrics_ladder ml
where ml.metric_id in (80,81,82,83,84,85,86,87,88,etc...)
-- only consider securities with fiscal year end not equal to december
and ml.security_id in (select security_id from company_details where fiscal_year_end <> 'dec')
)
insert into @calendar_averages
select temppivot.security_id
-- Net Income
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[80])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[81]) as [101]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[81])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[82]) as [102]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[82])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[83]) as [103]
,NULL as [104]
-- Share Holders Equity
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[84])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[85]) as [105]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[85])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[86]) as [106]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[86])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[87]) as [107]
,NULL as [108]
-- Capex
-- Sales
-- Accounts payable
etc...
..
..
from temp
pivot
(
sum(value)
for metric_id in ([80],[81],[82],[83],[84],[85],[86],[87],[88],etc...)
) as temppivot
inner join company_details cd on temppivot.security_id = cd.security_id
*********
END SQL
*********
The result then needs to be unpivoted and stored in metrics_ladder.
And FINALLY, the question! Is there a more elegant way of achieving this??? I have complete control over the database schema so if creating mapping tables or anything along those lines would help it is possible. Also, is SQL not really suited for such operations and would it therefore be better done in C#/VB.NET.
Many thanks (if you've read this far!)

Hi all,
I am trying to insert some new rows into an existing SQL table. The table name is Agt_table, and I want to add some data for some new agents into existing columns:
Agent name, agent code, phone number, fax number
Example -
I want to add the following record to my existing table Agt_table
Agent name: ABC Company
Agent code: 012345
Phone #: 555-555-5555
Fax#: 555-555-5555
How would I write the sql statement to do that?
Thanks so much!!!

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 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,

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

Below is a simplified table & dataset to illustrate a problem I'm experiencing with a more complex one.
Code Block
create table #test(
recno smallint PRIMARY KEY,
value decimal (18,2))
insert into #test values (1, 3.57)
insert into #test values (2, 5.32)
insert into #test values (3,6.29)
insert into #test values (4, 9.25)
insert into #test values (5, 0.84)
Method 1: I tried inserting rows from #test into a temp table (#table) as follows
Code Block
declare @n as nvarchar(3)
set @n = 1
while @n <= (select count(recno) from #test)
begin
exec ('
insert into ##table
select *,
originalrecno = (select recno from #test where recno = '+@n+')
from #test'
)
set @n = @n + 1
end
However, this yields an error message:
Code Block
Server: Msg 208, Level 16, State 1, Line 2
Invalid object name '##table'.
Note - you can comment out the insert into ##table line above to view the results that I'm trying to put into ##table.
Method 2: next I tried explicitly creating ##table & rerunning the loop containing the insert
Code Block
create table ##table (
recno smallint,
value decimal (18,2),
originalrecno smallint)
declare @n as nvarchar(3)
set @n = 1
while @n <= (select count(recno) from #test)
begin
exec ('
insert into ##table
select *,
originalrecno = (select recno from #test where recno = '+@n+')
from #test'
)
set @n = @n + 1
end
This worked - it inserted the data from the select statements in the loop into ##table.
Question - why won't method 1 work?

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.
Code Block
create table #Codes (itemID nvarchar(2), standarditem int)
insert into #Codes values (1,1)
insert into #Codes values (2,0)
insert into #Codes values (3,1)
insert into #Codes values (4,1)
insert into #Codes values (5,0)
create table #Cases (caseID nvarchar(5), scenarioID nvarchar(15), createdate datetime)
insert into #Cases values (823, 1, '20071210')
insert into #Cases values (823, 2, '20071211')
insert into #Cases values (824, 1, '20071213')
create table #Data (caseID nvarchar(5), scenarioID nvarchar(15), itemID nvarchar(2), itemvalue decimal (18,0))
data in #Codes:
itemID standarditem
1 1
2 0
3 1
4 1
5 0
data in #Cases:
caseID scenarioID createdate
823 1 2007-12-10 00:00:00.000
823 2 2007-12-11 00:00:00.000
824 1 2007-12-13 00:00:00.000
desired result in #Data:

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

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

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

I am ultra new to this so thanks in advance for any help.
I was trying to create a connection to a database that I created in SQL Express. I am essentially trying to submit three attributes to the existing database from a table that consists of three textboxes and a submit button. I would like all of the code to be in the head of the page (because that is the standard here) so I wanted to know what the connection string should be in Visual Basic 2005 Express to establish a connection on the same machine. I'm not sure about the connection string, but I am also not sure about a lot of the code. Also, the Using clauses seem to give me an error (where should it go?). This is what I have in the head of the page (visual C# by the way). Also, I got this from http://www.csharp-station.com/Tutorials/AdoDotNet/Lesson03.aspx :
Using System.Data;Using System.Data.SqlClient;protected void Button1_Click(object sender, EventArgs e){SqlConnection conn = new SqlConnection("Data Source=(local);Database=CustomersDB;Trusted Connection=true");conn.Open();string insertstring = @" insert into Catagories (CustomerID, CustomerName, CustomerEmail) values (" + textbox1.value + ", " + textbox2.value + " + ", textbox3.value");SqlCommand cmd = new SqlCommand(insertstring, conn);Sql.ExecuteNonQuery();conn.close();}
If there is absolutely any insite into the problems with my code, I really appreciate it.

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've got a piece of code that returns 53 records when using just the SELECT section.When I change it to INSERT INTO ..... SELECT it only inserts 39 records into the receiving table.There are no keys/contraints/indices or anything else on the receiving table (it's just a dumping ground for some data that will be processed later).
The code for creating the table is here:-
USE [CDSExtractInpatients6.2]
GO
/****** Object: Table [dbo].[CDS_Inpatients_CDS_Feeds_Import] Script Date: 22/05/2015 15:54:15 ******/
SET ANSI_NULLS ON
GO
[code]...
I know most of the date fields are being created as varchar on here, but this is something I inherited and the SELECT is outputting the dates as text.Don't know if it makes any difference, but the server is running SQL2008.

I am having troubles trying to copy some rows from a table on my local computer to a table on a remote SQL Server 2005 that is being hosted by one of thos web hosting companies. The problem is that the table has an identity column. I first tried using the the following command:
SET IDENTITY_INSERT [remoteservername].Library2005.dbo.tblLanguages ON
but that results in the error:
Msg 8103, Level 16, State 1, Line 1
Table 'remoteservername.Library2005.dbo.tblLanguages' does not exist or cannot be opened for SET operation.
I read in another topic, that I should change this into the following:
EXECUTE [remoteservername].Library2005.dbo.sp_executesql N'SET IDENTITY_INSERT dbo.tblLanguages ON'
That command executes without error, but the problem is that I cannot perform the actual insert, because it is not within the execute statement. In other words, the following doesn't work:
EXECUTE [remoteservername].Library2005.dbo.sp_executesql N'SET IDENTITY_INSERT dbo.tblLanguages ON'
INSERT INTO [remoteservername].Library2005.dbo.tblLanguages
(colLangID, colEnglish, colGerman, colSpanish)
SELECT colLangID, colEnglish, colGerman, colSpanish FROM tblLanguages
This results in the error:
Msg 7344, Level 16, State 1, Line 2
OLE DB provider 'SQLOLEDB' could not INSERT INTO table '[remoteservername].[Library2005].[dbo].[tblLanguages]' because of column 'colLangID'. The user did not have permission to write to the column.
The remote server is linked correctly on my end via the sp_addlinkedserver and sp_addlinkedsrvlogin. Is there any way to force the remote server to turn IDENTITY_INSERT ON permanently and then let me execute as many INSERTS as I want and then turn it back OFF?

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(??)

Hi there, I'm using CF2.0 SP1, with sqlce.
I have a 5MB delimitered file with 60,000 rows.
I need to insert it into a table in the PDA.
Once I start the procedure that inserts the table, the PDA's memory drops by 20-30 MB and every once in a while i get a
"Out OfMemory" exception...
Basically I send an insert command for every row in the text file cause last time i've checked, multiple rows insert per call wasn't yet implemented in the Sql Mobile...
Correct me if i'm wrong...
Code Block
StreamReader sr = new StreamReader(file, System.Text.Encoding.GetEncoding(1255));
line = sr.ReadLine();
clsAceProduct ace = new clsAceProduct();
//Read the first line of text
//Continue to read until you reach end of file
while (line != null)
{
//Send the Insert SQL Command
ace.Fill(line.Split(x));
bInsert=InsertAceProduct(ace);
if (bInsert)
{
l++;
}
//Read the next line
line = sr.ReadLine();
Thanks.

Hi,
First time poster here, basically I have a second year university module on database design and for our coursework we have to model and create a database. One of the questions asks us to create a table that has a constraint on how many rows it can contain. I now that this is possible in some other databases, however I haven't seen a constraint that I could use on create table to limit the number of rows.. Does anyone now if this is possible?
Thanks,
Al
