Different Behaviors When Writing Database File Into The SD Memory Card.
Feb 21, 2007
Hi All,
I have seen some different behaviors when I am writing SQL Server compact edition Database file into SD Memory card or any user removable storage media.
The following Steps for reproducing these behaviors.
1. Set your database location is in the SD Memory card.
2. Create a database and establish session.
3. Writing first record into the database is done
4. Remove your SD card manually from the system
5. Try to write a Second record into the database
6. You will get the error from this "SqlCeWriteRecordProps" API call - This is fine.
7. Put your SD card back into the system.
8. Writing Second record again into the database is done - This is fine.
So far the behaviors are good after that
9. Remove your SD card manually from the system again
10. Try to write a Third record into the database
11. You will suppose to get the error from this "SqlCeWriteRecordProps" API call but you won€™t get that error €“ I don€™t know why?
12. Then Try to write a Forth record into the database
13. You won't get any error from the API call "SqlCeWriteRecordProps" and return status is success.
14. Now put your SD card back into the system.
15. Then write Fifth record but this time its writing record Third, Fourth and Fifth into the database.
Note:
I am clearing (means Free) my record structure everything after calling this function "SqlCeWriteRecordProps". So I don€™t know why its wring Third, fourth and fifth record into the database.
Please Let me know your feedback.
Thanks,
Rajendran

Hello,
Is there any ability to do database-level triggers in SQL 2000? I have a SQL 2000 database, and I was asked if we could create a trigger that whenever anyone touches the data in a database, to create an entry in an event log? If not, I have a main table I can put a trigger on; however, my question is how do you write to a file in a trigger as well?
Thanks.

Hey everyone I've got this question that has me stuck for the last few days but its an important part of my website.....What I am trying to do is basicly have a user be able to upload a file, have that uploaded file plus some other info automaticly display on other parts of my site, and have a different user eventually be able to download that file....I have thought about allowing the file upload as a BLOB but still cannot find a proper way to execute this using VB, plus I have heard that this way of doing it is not reccommeneded cause databases were not designed to store large files like this, lots of articles recommened having the file upload to a Folder on your server then get the binary data for the file that can be placed in a database to refrence that particular file.....Well this also proves to be a lot harder then said here is what I got so far (written in C#) protected void UploadBtn_Click(object sender, EventArgs e)
{
if (FileUpLoad1.HasFile)
{
FileUpLoad1.SaveAs(@"C:Documents and SettingsAdamMy DocumentsVisual Studio 2005ProjectsWebsiteFiles" + FileUpLoad1.FileName);
Label1.Text = "File Uploaded: " + FileUpLoad1.FileName;
}
else
{
Label1.Text = "No File Uploaded.";
}
}
and here is the asp part of the code that goes with it<asp:FileUpLoad id="FileUpLoad1" runat="server" />
<asp:Button id="UploadBtn" Text="Upload File" OnClick="UploadBtn_Click" runat="server" Width="105px" />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
Now from what I know is I need to get the binary of the file which I have read you can do with the Page.Request.Files statement but again not sure how I would impliment this. Does anyone have any suggestions on which way I should take when dealing with this should I try and just use the BLOB method or use the binary refrence method? and if so how would I impliment this, heck even some good tutorials on the subject would be great... Thanks.....Adam

Hi all.
I develop a app on PPC 4.20 using SQLServer 3.1. I developed a o/r mapper whitch auto-creates the Database and Tables using attribute-decorated objects. That all works fine - as long as my Database is in \MyDocuments .
Trying to store the Database in \Storage Card\test.sdf, whitch is absolut neccessary because it will become to big for storing onto device, I get error 25113, "A not supportes operation to host was called" (Translated from German)
When I trie to copy a Database to the SD-Card, inserts are not commited.
Is it not supported to store Databasefiles on a Flashcard?
My development-environment is .net 2.0 sp2, device-emulator v2, Windows XP, vs2005. In the emulator, i have linked a windows-based directory as storagecard.
What am I doing wrong??
class SQLManager
{
private static SQLManager instance = null;
private SqlCeEngine m_cEngine = null;
private SqlCeConnection m_cConn = null;
private SQLManager()
{
m_cEngine = new SqlCeEngine(
"Data Source = \Storage Card\test.sdf");
bool bCreated = false;
if (!File.Exists("\Storage Card\test.sdf"))
{
bCreated = true;
m_cEngine.CreateDatabase();
}
m_cConn = new SqlCeConnection(
"Data Source = \Storage Card\test.sdf");
m_cConn.Open();
if (bCreated)
DoInitialDatabaseSetup();
}
....
}

Hi!I have a stored procedure that takes 22 minutes to run in oneenvironment, that only takes 1 sec or so to run in anotherenvironment. Here is the exact situation:Database 1 on Server 1 vs. Database 2 on Server 2 - the data isexactly the same, and the tables and index structures are exactly thesame. Implicit transactions are turned off on both databases.Stored procedure:BEGIN TRANSACTION--step 1TRUNCATE myTable--step 2INSERT INTO myTable VALUES ('myValues')--step 3UPDATE aSET rating=AVG(someValues)FROM myTable aJOIN otherTable bON a.column1=b.column1GROUP BY someColumnsCOMMIT TRANSACTIONThe update statement on the problem server is the only step that takesforever. While it is running, I don't see anything that could beblocking the statement. I used the following queries to determine ifthere was another process blocking it:select spid AS Blocked, blocked AS Blocking, waittime, cmd, substring(nt_username, 1, 15), dbid, physical_io,substring(hostname, 1, 15), program_name, lastwaittype, waitresource,memusagefrom master.dbo.sysprocesses where blocked <0order by waittime descselect dbid, name from sysdatabases where dbid in (select dbid frommaster.dbo.sysprocesses where blocked <0)select spid AS BlockingFromAbove, blocked AS TrueBlockingQuery,waittime, cmd, substring (nt_username, 1, 15), dbid, physical_io,substring(hostname, 1, 15), program_name, lastwaittype, waitresource,memusagefrom master.dbo.sysprocesses where spid in (select blocked frommaster.dbo.sysprocesses where blocked <0)order by waittime descWhen I change the UPDATE statement to a SELECT, it still takes longerthan it does on the test server (1 min 35 sec vs. severalmilliseconds).What could be causing the UPDATE to take forever on one server/database, and run without a problem on another?I am at a loss! Any help would be greatly appreciated.

I'm sure I'm not the only one frustrated trying to figure out which log file SSRS writes to when an error occurs. Does anybody know a sure way to tell? It doesn't change the date/time of the date modified, so you can't sort by date in windows explorer. There seems to be no rhyme or reason to which file it writes to. For example, I had to go through 6 log files to find which one was being written to. I had thought (hoped) that it would always write to the log files with the latest embedded date/time stamp as part of the file name. It does not.
I'm tempted to start using a file system spy, or resort to other tactics. Does anyone have a sure fired way to see which log file is written to when an error occurs? I'm not talking about SQL Dump files - just "normal" errors when processing reports.
Thanks,
WillyDog

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.
Cheers ~ J

Hi
I have a data flow task where I have to write to a flat file. It works fine for me. But the thing is next timeI run the package it must write the data in the OLDEB source to a different copy. Usually the data is overwritten or appended to already existing data. What I want is everytime the package is run the data must be written to a different copy.
Thanks

I have a Foreach loop which scans a table, and gets names of a bunch of procedures, and then back in the foreach loop, they get executed. Im trying to figure out how I can create a sort of log file to say the name of the procedure that is getting executed currently and the current date time stamp onto a flat file. I havent been able to figure this out yet..anyone know how to do this? I grab the names of the storedprocedures from the table and store it in a variable and use the name from the variable to actually execute the stored procedure.
I guess in essence, the question is how do i directly write lines of 'text' (from say a variable) into a flat file.

I'm doing a test package which reads a flat file, makes an adjustment using the derived column task and writes to the same flat file. But, the read locks the flat file, so the write can't access it. Any ideas for a resolution?

Lastly I want the columns to have a width that is fixed.
How I can do this.

I am trying to create a text file from multiple SQL Tables using @BCP_Command. I tried using DTS and SQL but the number of columns in the tables have to be the same size when doing a union. I also not to place a delimeter between each column. I've learned how to use BCP_commands on one file not sure if you can make it work with two or more.

Want to write from a table variable to a text file from a stored procedure.Read about xp_cmdshell bcp etc. but worried because it's supposed to be a security problem and needs to be from a permanent database.Also am getting error "The EXECUTE permission was denied on the object 'xp_cmdshell'..."
1. Is xp_cmdshell a bad idea to use even if I get permissions ?
2. Can a "permanent" table be used in a stored procedure starting out fresh each time with 0 rows rather than use a table variable ?

I'm writing to a flat file destination (CSV file) which contains 2 header rows, lets call it Col1 and Col2.
For some reason, the header rows seem to get duplicated in the output - i.e.
Col1,Col2
A,B
Col1,Col2
C,D
Is there any way to resolve this?
I don't want the file to be overwritten everytime since its used for record-keeping purposes.
Thanks

I got this error yesterday running an SSIS package:
"The buffer manager cannot create a file to spool a long object on the directories named in the BLOBTempStoragePath property. Either an incorrect file name was provided, or there are no permissions."
This same package was working fine on a different server, so I compared the configurations of the two boxes. It turned out that the service account that runs the package was in the Windows Administrators group on one box but not the other. I added the service account to Administrators on the box that had the problem and the problem went away.
I have looked around and have not found a list of the necessary Windows permissions that an account must have in order to run an SSIS package. This list would include write permissions to the path specified in BLOBTempStoragePath. Has anyone out there configured an account with minimal permissions to run a package that has a Data Flow?
Thanks,

I'm unable to figure out how to write a column header to my flat file destination. My source is a OLE DB SQL query and I need the column names as a header row in my text file destination. This seems easy but the closet I can find is hardcoding the column header row in the header property. Is this the only option?
Thanks

Flat file is the source for to load the data into a table. I am using "Derived Column Component" for the data validation.
"Derived Column Component" Fails then i am writing/redirecting the records into the Flat File using "Flat File Destination" component.
It works fine except the following the issue.
Issue:
The derived columun value (that cause an error) is not get inserted into the Flat File
Scenario:
the data comes as "000000" and tring to convert to date format
(DT_DATE)("20" + RIGHT(Check_Date,2) + "/" + SUBSTRING(Check_Date,1,LEN(Check_Date) - 4) + "/" + SUBSTRING(Check_Date,LEN(Check_Date) - 3,2))
The above expression is working fine, except the data 000000 not passed into the Flat File Destination.
Pls advise. Thank you.

I have a set of parent/child records that need to be exported to a space delimited Flat File. Each parent record must be followed by 3 child records, each on their own line with different format.
I have a prototype using the Derived Column component that concatinates the various fields of each record into one "wide" text column. This fools SSIS to think that each row has the same format. Then I merge them together using an artificial sort id. But this seems overly tedious and very brittle.
What would be the best approach to writing these records out? I'm hoping there is a better more maintainable method.
Thanks,
Jon

Hi,
I am trying to write to a fixed format flat file using Flat File Destination Data Flow Component. I have all required information gathered from more than one sources. But when I tried to format the columns to a big string that will make up one line in the flat file, I could not figure out how to do that. Couple of issues that I am facing are:
How to padd different columns? For example, One interger column has could be 1 to 10 character long in my case. When I convert to string, dont know how to padd the remaining characters i.e. if the value of integer is '1234', it should be written to file as '1234 ' . Which transformation is best in this case, if available?
How to convert T-SQL datetime to a specific date and time format to write in the flate file? I have to write these date formats depending upon one of the parameters passed.
Also, I dont want to put a delimiter at the end of each column, just the new line characters at the end of each record.
Some of the columns has some unwanted characters (like new line characters) how to find them and remove them from the string.
Can we directly write columns to a specific position in the flat file? e.g. col 1 a position 1 and col2 starts at postion 20 etc.
Your co-operation will be appreciated.
Thanks,
Paraclete

I have a variable defined as "Country". Based on the value, the header row printed needs to be different.
I've already created a 'HeaderRow' variable that I'm able to set using a script task. But how can you set the Header text value at run time from the variable? There is no expression defined for the Header with the Flat File Destination object, and when I attempt to reference the HeaderRow variable as the Header text, the variable name is printed as the header.
Another approach I tried was to write the Header Row separately through another data flow task, but the issue here is: what is the input source when all you have is a Country variable?
