Can't Find Out Where This Insert Is Happening.....
Sep 6, 2007
Hello people, I don't expect anyone to know the answer to this but I guess we'll see huh?
I'm using Microsoft SQL Server Management Studio to do all my SQL stuff, and one of the tools that comes with this is a program called Microsoft SQL Profiler 2005. Anyways, so I'm using this profiler to capture SQL processes in the background while I work with the front end.
Here is a problem I'm facing... I am looking at this table right... and I see that when I do this certain process on the front end, it inserts 3 rows into the table. So I'm thinking "I know that on the tracer, I should be looking for an insert or a Stored Procedure with and insert in it."
So I use the tracer on the front end process and it shows me all the stored procedures that happen during the process of inserting these 3 rows into this table (btw this process is doing other things besides inserting stuff into this table, but it's what i'm currently working with at the moment.)
So what I do here at my job is I take this code, tweak it to work for our front end, and wah lah.... we're good to go. So in saying that, I make my own stored procedure and I all these stored procedures that are happening.
My result......
I get only 2 row inserts into the table.... the 1st row and the last row..... the middle row isn't inserted for some mysterious reason. I tried checking all the stored procedures for unique information pertaining to that specific row insert but to no avail I couldn't.
So my question to you guys is.... is there anything I'm overlooking that could possibly be inserting that row in the table? Thanks guys!

Hi,
I set up my package for logging to SQL Server. I set up a connection manager for the logging, but did not specify a database. Doesn't that mean that the logging should default to msdb.sysdtslog90?
But when I check the table, there's nothing in it, after I run the package.
What gives?

Hi
I have deployed a website on a server having Windows2000, IIS5.0 . It uses SQL Server 2000 which is on another remote server. While developing I used the visual tools in VS.net to make a connection and have used DYnamic properties of the connection object to map the connection string to the entry in to the config file.
This works fine on my developement machine which has IIS and SQL Server 2000 on the same machine.
The entry in the web.config for my connection string is:
value= " server=xxx.yyy.com; Trusted_Connection=yes;provider=SQLOLEDB.1;Initial Catalog=events; User id=myuser; Password=password;"
where xxx.yyy.com is the server running SQL Server2000.
I do not get any error but the conncetion doesnot happen and my datagrid doesnot get filled.
The code for creating the connection is designer generated code.
Any clues?

I have two problems I need some help with.First, I've just inherited a system and am delving into a few timeoutproblems that are causing problems for the users.Now, if I do a simple select * from the table (which looks to be thecause of the problem at this stage) in QA, I get the results back inless than a second. If I open the table in EM it takes about 10. Isthere a difference in viewing the data this way ? I'm used to EM beingvirtually the same speed. There is only one row. Minor questionreally, just something I'd like to understand if there is adifference.CREATE TABLE [QUERY] ([QUERY_ID] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[CAT_ID] [numeric](18, 0) NOT NULL ,[QUERY_DESCR] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOTNULL ,[USER_NAME] [varchar] (40) COLLATE SQL_Latin1_General_CP1_CI_AS NOTNULL ,[USER_ID] [int] NOT NULL ,[IND_EURO] [char] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULLCONSTRAINT [DF_QUERY_IND_EURO] DEFAULT ('N'),[IND_DGCOLUMNS] [char] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NOTNULL CONSTRAINT [DF_QUERY_IND_DGCOLUMNS] DEFAULT ('N'),[NO_GROUPS] [int] NOT NULL CONSTRAINT [DF_QUERY_NO_GROUPS] DEFAULT(0),[NO_FIELDS] [int] NOT NULL CONSTRAINT [DF_QUERY_NO_FIELDS] DEFAULT(0),[NO_LINES] [int] NOT NULL CONSTRAINT [DF_QUERY_NO_LINES] DEFAULT (0),CONSTRAINT [PK_QUERY] PRIMARY KEY CLUSTERED([QUERY_ID]) WITH FILLFACTOR = 90 ON [PRIMARY] ,CONSTRAINT [FK_QUERY_QUERY_CATEGORY] FOREIGN KEY([CAT_ID]) REFERENCES [QUERY_CATEGORY] ([CAT_ID]) ON DELETE CASCADE ON UPDATE CASCADE) ON [PRIMARY]GOI don't think any re-indexing has been done on this (or the othertables in the db). I was wondering if constant adding/deleting rowscould cause the index to be massive and in need of a good clear out.Any pointers would be appreciated. From what I can tell, there wassome problems trying to get replication to work. I need to dig deeperto see if this is now correct.-------------------------Secondly, there is a another table in the same database.CREATE TABLE [FIELD_DATA] ([ID] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[DATA_ID] [numeric](18, 0) NOT NULL ,[FIELD_ID] [numeric](18, 0) NULL ,[FIELD_CODE] [varchar] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NOTNULL ,[FIELD_VALUE] [numeric](15, 5) NULL ,CONSTRAINT [PK_FIELDDATA] PRIMARY KEY CLUSTERED([ID]) WITH FILLFACTOR = 90 ON [PRIMARY]) ON [PRIMARY]GOIt holds approx 4 million rows. The rest of the tables have minimaldata and about the same amount (consider them the same if you will).Now, another 'copy' of this database is held elsewhere (differentclient data) and this holds 40 million rows. The difference is thatthe first DB is 4.5GB and the second 6.5GB (approx). Does this provemy theory that re-indexing would be a good idea ?ThanksRyan

hello all,
i am making a query which select the data again a particuler date.
I insert values in the table for with current date(Today's date) and the records is inserted with the date format(2006-07-14 16:12:09),now when i run the query after 2 or 3 minutes to select the records inserted today, my query returns no results.
I think it is because of the the time (14:16 in this case) that after 2 minutes, the query looks for the records inserted at (2006-07-14 18:12 or 2006-07-14 19:12) and does not get the result.
Is there a method to not consider the time(14:16) when running the query but the query fetches the records including the records inserted at this time(14:16) no matter at what time I run the query today?
Please anyone help me!
Thanks in advance!

declare @error int, @rowcount int
select @rowcount = COUNT(1) FROMÂ STG_BCDR;
while @rowcount > 0
begin
 BEGIN TRAN Deletion
[code]....
Above code i try to delete records batch by batch to avoid table locking at BCDR table.total records in this BCDRÂ table is 40,000 records. Â However I run the code at execution plan, the BCDR table still clustered index scan which means that the locking still happend.
If i change the delete top (5000)...... to delete top (5).... then thre is clustered index seek, which is good..The problem here is  each time  only delete top 5 records which is means it will realy take very long time to remove those data.
how to cater the situation inorder for me to delete those huge data without table locking happend. If table locking happend , then other user will not be able to access this table at the same time.

I have two VB.NET dataclient program A abd B.
What i want to do is .. to find the best way to insert the high speed data( that comes at every 10 ms) to the sql server express database table .
I have two options to store the data in the table . One is to insert all the data in one row , the other is to divide it into many rows in the same table . In approach A i will get like 10 records per second and in approach B i may get i may get 30 - 50 records per second based on the amount of data that is comming . i.e i am creating a new row in the table for every extra column added in Approach A and duplication the other columns.
I wanted to find the better way to insert the data based on the performace metrics like CPU usage and memory usage.

I tried all the INFORMATION_SCHEMA on SQL 2000 andI see that the system tables hold pretty much everything I aminterested in: Objects names (columns, functions, stored procedures, ...)stored procedure statements in syscomments table.My questions are:If you script your whole database everything you end up havingin the text sql scripts, are those also located in the system tables?That means i could simply read those system tables to get any informationI would normally look in the sql script files?Can i quickly generate a SQL statement of all the indexes on my database?I read many places that Microsoftsays not to modify anything in those tables and not query them since theirstructure might change in future SQL versions.Is it safe to use and rely the system tables?I basically want to do at least fetching of information i want from thesystem tables rather than the SQL script files.I also want to know if it's pretty safe for me to make changes in thesetables.Can i rename an object name for example an Index name, a Stored Procedurename?Can i add a new column in the syscolumns table for a user table?Thank you

I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

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

Hello, I'm new to the forum and new to SQL, ASP.NET, etc. I am creating an intranet site for my company in VS 2005 and have run into a very annoying problem that I can't seem to solve. I have tried Googling it and came up empty. I have a database in SQL Express 2005 and my website will be accessing several tables within the database. I can retrieve info just fine and I can update, delete, etc just fine using gridview or other prebuilt tools, but when I add a few text boxes and wire a button to the SqlDataSource.Insert() command, I get a new record that is full of null values except for the identity key I have set. The kicker is that I am also using a master page and when I duplicate the web page without the master page link, everything works just fine. The following snippets show what I'm doing:<InsertParameters><asp:FormParameter Name="Name" Type="String" FormField="txtName" /><asp:FormParameter Name="Location" Type="String" FormField="ddlLocation" /><asp:FormParameter Name="Issue" Type="String" FormField="txtProblem" /></InsertParameters>Of course I match the formfields to the text boxes, create an onclick event for my button, the sqldatasource is configured correctly, it just doesn't work with the master page no matter what I do. Any help would be appreciated. Thanks

On my site users can register using ASP Membership Create user Wizard control.
I am also using the wizard control to design a simple question and answer form that logged in users have access to.
it has 2 questions including a text box for Q1 and dropdown list for Q2.
I have a table in my database called "Players" which has 3 Columns
UserId Primary Key of type Unique Identifyer
PlayerName Type String
PlayerGenre Type Sting
On completing the wizard and clicking the finish button, I want the data to be inserted into the SQl express Players table.
I am having problems getting this to work and keep getting exceptions.
Be very helpful if somebody could check the code and advise where the problem is??

This problem is being seen on SQL 2005 SP2 + cumulative update 4
I am currently successfully using the output clause of an insert statement to return the identity values for inserted rows into a table variable
I now need to add an "instead of insert" trigger to the table that is the subject of the insert.
As soon as I add the "instead of insert" trigger, the output clause on the insert statement does not return any data - although the insert completes successfully. As a result I am not able to obtain the identities of the inserted rows
Note that @@identity would return the correct value in the test repro below - but this is not a viable option as the table in question will be merge replicated and @@identity will return the identity value of a replication metadata table rather than the identity of the row inserted into my_table
Note also that in the test repro, the "instead of insert" trigger actually does nothing apart from the default insert, but the real world trigger has additional code.
To run the repro below - select each of the sections below in turn and execute them
1) Create the table
2) Create the trigger
3) Do the insert - note that table variable contains a row with column value zero - it should contain the @@identity value
4) Drop the trigger
5) Re-run the insert from 3) - note that table variable is now correctly populated with the @@identity value in the row
I need the behaviour to be correct when the trigger is present
Any thoughts would be much appreciated

Hi All
I decided to change over from Microsoft Access Database file to the New SQLServerCe Compact edition. Although the reading of data from the database is greatly improved, the inserting of the new rows is extremely slow.
I was getting between 60 to 70 rows per sec using OLEDB and an Access Database but now only getting 14 to 27 rows per sec using SQLServerCe.
I have tried the below code changes and nothing seams to increase the speed, any help as I would prefer to use SQLServerCe as the database is much smaller and I€™m use to SQL Commands.
Details:
VB2008 Pro
.NET Frameworks 2.0
SQL Compact Edition V3.5
Encryption = Engine Default
Database Size = 128Mb (But needs to be changes to 999Mbs)
Where Backup_On_Next_Run, OverWriteQuick, CompressAns are Booleans, all other column sizes are nvarchar and size 10 to 30 expect for Full Folder Address size 260
TRY1
Direct Insert Using Data Adapter.
Me.BackupDatabaseTableAdapter1.Insert(Group_Name1, Full_Folder_Address1, File1, File_Size_KB1, Schedule_To_Run1, Backup_Time1, Last_Run1, Result1, Last_Modfied1, Last_Modfied1, Backup_On_Next_Run1, Total_Backup_Times1, Server_File_Number1, Server_Number1, File_Break_Down1, No_Of_Servers1, Full_File_Address1, OverWriteQuick, CompressAns)
14 to 20 rows per second (Was 60 to 70 when using OLEDB Access)

End Try
End Sub

Is this the best you can get or is there a better way. Any help would be greatly appericated
Kind Regards
