Data Lost After INSERT Command
Dec 21, 2006
I have a website that is used to enter dates from a calendar. For example, user A might go to the website and select 20 different days in January. When user A clicks on the Save button the dates are written to the database with an INSERT command. This works fine. However, when user B then goes through the same procedure, say selecting 5 dates that are in the set selected by user A, those dates are properly saved in the database but the rows containing user A's same 5 dates disappear. I suspect this is something simple but I'm new and ignorant. Please help.

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??

Hi there,I am not sure how many of you have experienced this problem before but here is how to replicate it: Add a GridView, SqlDataSource and Button to a new projectSet the DataSourceID to the SqlDataSource objectSet AllowPaging to True on the GridViewWithin the Button1_Click sub, change the SqlDataSource.SelectCommand to a new Query e.g SELECT * FROM table WHERE ID > 1Run the project Click on another page, i.e. "3" on the GridView SqlDataSource.SelectCommand is now blank(!), thus Gridview displays nothing. Has anyone else found a solution to this annoying issue? Any help is appreciated.Regards

We lost all the data we had in a table. We restored the db and the transaction log up to a point in time, but could still not recover the table. We eventually only do db restore without the transaction log. We recovered the data in the table in question, but lost all the data entered that particular day. Does any body have a solution or suggestion that can help? I will be greatly appreciated.

Copy both Saturday 4PM and Friday night full dump to the SAN.3.) Delete WinNT4.0.4.) Reinstall Win2003 and service pack3a.5.) Copy Saturday 4PM backup file to the server and do restore and douser ID mapping.This database is in full mode and I do log backup every hour. However,after restoring the database, any changes after the 14th were missing.Now, When I restored Friday night backup, we still recovered data tothe 16th. My question is, why the 17th 4PM backup did not copy anychange from 15th to the 17th Saturday?I still had Sturday backup file, howe can I recover the 17th data? Logexplorer or ApexSQLLog?Is this Disk issue?Thanks very much,Silaphet,

Hello All,
Thanks in advance for your help.
I am wondering if there is a correlation between the size of a database and the amount of RAM required in the server. Here's what's going on:
NT4.0 SP 6a, SQL 7.0
2-800 MHz Pentium III Processors
512 MB RAM
Swap Files: two, divided evenly between two partitions, min 512 per partition (dynamic)
3- 9.2 GB Drives, RAID 5
SQL Database size: 2.5 GB
The SQL administrators have a scheduled job set to dump the database every four hours, so they have 6 of these dump files per day. Seagate Backup Exec v 6.? backs up those files every evening. Of course, this is a mission-critical application.
As the NT/Hardware administrator, I was tasked to flash upgrade all the hardware that could be flashed. That happened about three weeks ago. Ever since I flashed it, getting the data dumps has been an inconsistent process. Sometimes it works, sometimes it errors out. The error message is " Lost Delayed - Write Data: The system was attempting to transfer file data from buffers to (path). The write operation failed, and only some to the data may have been written to the file."
On and off during the day, you can't even copy a small file on the server without receiving the same message.
Before I flashed the server, it was blue-screening and needing to be rebooted about once every two weeks. Since I flashed it, the server hasn't been rebooted, because it hasn't blue-screened.
The database dumps are about 2 GB. We were thinking that the way the dump process worked was that a snapshot of the data was put into memory before it was written to disk. We thought since the dump size was larger than Physical Memory + Virtual Memory, that that could be causing the error.
What do you guys think?
1. Is dumping the database first the preferred way to get a backup, or should a backup directly to tape be scheduled instead?
2. Do we have enough RAM for the database?
3. Are there special settings we should set for the RAID controller card to maximize throughput for SQL?
Thanks again. I am definitely not a SQL DBA and any information you can provide would be really helpful.

I am migrating from 2000 to 2005 and in the process of rewriting DTS to SSIS. So far so good.
I have an import of a flat file that I need to reproduce that works fine in DTS but throws SSIS.
The file contains details of products, and has a Long Description field that may contain lots of different chars - CR & LF amongst them. It's source and destination columns are Text type.
The file is tab delimited, text delimited with double quotes, with row delimiters of CRLF and column names on row 1.
The error SSIS throws is "The column delimiter for column "LongDescription" was not found"
I imagine (perhaps wrongly) that this is because of the extra CRLFs but it worked fine in DTS. It also previews fine, and lets me define the column properties OK in SSIS package designer.
Any help greatly appreciated. I am trying to avoid the obvious thing of replacing those chars in that field at this point as currently the export is shared between a live production server, and my test 2005 rig.
Thanks v much.
Chris.

I know that anything in a CDATA section will be ignored by an XML parser. Does that hold true for the SSIS XML Source?
I am trying to import a large quantity of movie information and all of the reviews, synopsis, etc are contained in CDATA. example:
<synopsis size="100"><![CDATA[Four vignettes feature thugs in a pool hall, a tormented ex-con, a cop and a gangster.]]></synopsis>
Sounds like a good one, no?
The record gets inserted into the database however it contains a NULL in the field for the synopsis text. I would imagine that the reason for this would fall at the feet of CDATA's nature and that SSIS is ignoring it.
Any thoughts would be appreciated. Thanks.

Violation of PRIMARY KEY constraint 'PK_TE_shounin_zangyou'. Cannot insert duplicate key in object 'dbo.TE_shounin_zangyou'.The statement has been terminated.
Here's the insert command...
Dim update_phase As New SqlCommand("INSERT INTO TE_shounin_zangyou (syain_No,date_kyou,time_kyou) SELECT syain_No,date_kyou,time_kyou FROM TE_zangyou WHERE [syain_No] = @syain_No", cnn)

I have three tables t1, t2, t3. I want to insert a new row in t1. I am using access 2000 with sql commands for the queries. There are 4 colums in t1. I know the values of two of the colums. The remaining two columns values are going to be look up in the other 2 tables, 1 value from t2 table and the other value from t3.. I need this to be in one statement. From what I have seen you can either use insert with values() or you can populate your table with unkown values from another table. But I want to do both, since 2 of my values are known and the other 2 need to come from another table.
I hope that I made it clear enough. Can anyone help me

i am completely new to sql commands so i really need the help on this one.
I have three tables and they go like this
--User Table
firstTable->integerID
firstTable->stringName
--Group Table
secondTable->integerID
secondTable->stringName
--User to Groups table
thirdTable->integerFirstID
thirdTable->integerSecondID
thirdTable->stringDescription
the first table is has a user id and name and the second table has a group id and name, the third table keeps track of how many groups the user is assigned to. The problem i am having is writing a sql insert into command to add more entries to the third table from an asp.net 2.0 page, my sql command is incorrect.
The problem i am having i think, is that i am populating a dropdownlist with the names of all of the groups and when i select one that should be the group i am assigning to the user, the problem is, is that i dont know how to associated that dropdownlist string's name with its ID so that it can be passed to my insert command. is there a way to accomplish this all as a sql command? because i have a formview with a multiview and then a gridview under nested under all of that, and it would be a pain to write a event to work with all of the that.
if i do this it works
INSERT INTO ThirdTable (UserID,GroupID,Description) VALUES '318', '2', 'some description')
