Retrieve Text File Data In SSE For Data Acquisition System
Oct 24, 2007
Hey All,
I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form.
I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.

Hi Mates,
I am unable to fetch data from Source which is CSV file whose sample contents are given below:
-----------------------------------------------------------------------------------------------------------
"Fiscal year";"Posting period";"Company Code";"Functional area";"Profit Center";"Business area";"Group Account";"Posting Level";"Document Type";"Accounting Principle";"Cost Pool";"Financial Owner";"Period Value GC"
"2006";"12";"AR00";"A107";"P1131";"7200";"3410";"10";"18";"GAAP";"#";"#";"$ 0.00"
"2006";"12";"AR00";"A107";"P1131";"9600";"3410";"10";"18";"GAAP";"#";"#";"$ 0.00"
--------------------------------------------------------------------------------------------------------------
The error message that comes while I preview the source data:
Error:
"The Preview sample contains embedded text qualifiers. The flat file parser doesnot support embedding text qualifiers in data. Parsing columns that contain data with text qualifiers will fail at runtime"
Is there any alternative to remove these text qualifiers from the file. Do we have any utility that can convert these files into text qualifier free CSV file?

I have created a windows library control that accesses a local sql database
I tried the following strings for connecting
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"
I am not running the webpage in a virtual directory but in
C:Inetpubwwwrootusercontrol
and I have a simple index.html that tries to read from an sql db but throws
the error
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.PermissionSet.Demand()
at System.Data.Common.DbConnectionOptions.DemandPermission()
at System.Data.SqlClient.SqlConnection.PermissionDemand()
at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,
etc etc
The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted
I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security
I think that a windows form connecting to a sql database running in a webpage should be simple
to configure what am I missing?

The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.
Thanks,
Ray

I created a .net console application within which I connect to a sql server (not local) as follows,
string conn_str = "Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=QuantEquitySql;Data Source=server name";
SqlConnection conn = new SqlConnection(conn_str);
conn.Open();
.
Everything works fine when I run it from my computer. When I try to run it from a network share I get the following error,
Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I have a report that uses some embedded custom code. The embedded custom code is a function that execute some sql query on a sql server database.Everything works fine in Visual studio. The report gets deployed on the server successfully, however when running the report from report manager i get the following error message :

Why do i get the error message ?, is this related to Code Access Security issues with .net framework. if yes
how do i set the Security so the report server or report manager allows embedded custom code to be executed. Any advice ?

We just upgraded our applications from VS 2005 to VS 2008 and discovered we had to convert our SQL Server CE databases. So I did that. I then included the sqlce...35.dlls in the application directory on my test computer as well as the System.Data.SqlServerCe.dll version 3.5.
sqlceca35.dll
sqlcecompact35.dll
sqlceer35EN.dll
sqlceme35.dll
sqlceoledb35.dll
sqlceqp35.dll
sqlcese35.dll
When I run the app and it tries to load the System.Data.SqlServerCe.dll I get the following error:
System.IO.FileLoadException: Could not load file or assembly 'System.Data.SqlServerCe, Version 3.5.0.0...or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.
We have the application targeting the .NET Framework 2.0 and need to keep it that way for awhile.
Any ideas on how to resolve the error?

I'm trying to figure this out
I have a store procedure that return the userId if a user exists in my table, return 0 otherwise
------------------------------------------------------------------------
Create Procedure spUpdatePasswordByUserId
@userName varchar(20),
@password varchar(20)
AS
Begin
Declare @userId int
Select @userId = (Select userId from userInfo Where userName = @userName and password = @password)
if (@userId > 0)
return @userId
else
return 0
------------------------------------------------------------------
I create a function called UpdatePasswordByUserId in my dataset with the above stored procedure that returns a scalar value. When I preview the data from the table adapter in my dataset, it spits out the right value.
But when I call this UpdatepasswordByUserId from an asp.net page, it returns null/blank/0
passport.UserInfoTableAdapters oUserInfo = new UserInfoTableAdapters();
Response.Write("userId: " + oUserInfo.UpdatePasswordByUserId(txtUserName.text, txtPassword.text) );
Do you guys have any idea why?

If this is the wrong place for this question, would someone please tell me so. I am new to SQL Server and still feeling out resources. I have a few books on SQL Server but none cover this question.
I have a text file of dates and numbers that I want to insert into a table. There are way too many rows of data in the file to do this by hand.
Question == How can I essentially insert the text file into my table?
Thank you,

I am trying to find a convenient way to export parts of tables to text
files.
One way I see is BCP: Is there a way to avoid writing the command and
options into the command prompt by hand? I.e. a way to write the
commands into a text file and then to execute them?
Are there other ways? I`d like to find a way that a user who uses a web
interface can use.
Is there a way to send the text files via mail to a remote user?

Hi, I just started using SQL Server 2005 and I'm trying to find out how to do a sql dump on a table, but this is proving more challenging then it should be.
I usually use mysql with a program called navicat, and all you do is right click on the table and select dump... Inserting the data back in is just as simple. I have also used sql server 2000 awhile back and I know there was a dumping utility for it.
Can someone point me in the right direction on how to dump data to a .sql file and reinsert that data? Thanks!

I have text output files which are semi-structured.(Headers + irregular length tables below)
Is there a simple method of getting them into sql format(line by line) to try and extract data from them?
I know this won't be easy but its been worrying me for a long time. I have a method of importing the data into excel, but although difficult, it must be possible to get a system to get it into sql server. This must be a fairly common issue.

Hi everyone I have a directory that contains a lot of text files that have data I need to draw from. I want to know if it is possible to write a program that will read all of the text files in the directory and pull out data and save it to a new textfile. For example: Each text file is formatted this wayColumn1, Column2, Column3"1","xxxx","yyyy""2", "xxxx", "yyyy""3", "XXXX", "yyyy" I want to put all lines that begin with 1 in one text file, all the lines that begin with two in another text file, and the same with all lines that begin with 3. my problem is I want to be able to point at the folder that contains those files and have it read every text file in the folder and perform the operation. If this is possible can someone point me in the right direction on how to get started.Thank you for any help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi,
How would I be able to query a table (ie. all people with last name 'Smith'), have that set of data outputted to a regular text file (in a formatted way)
And what's the best way to manipulate that set of data to let's say update a Yes/No field in that table to mark that that those individuals('Smith') which were outputted in that text file?
What about the reverse? If I got a regular text file with Last Name, Social Security(delimited by tab), etc is there a way I can get SQL Server to read that text file and make an update to the database based on the Social security in that text file.
Any help would be immensely appreciated!

I need to export data from a table to a text file, where the data in the table is deleted after written to the file. It is simple using DTS, but I want to do the export in "chunks" of data, committing the delete say after every 1000 rows.
My thought was a stored procedure would be easy enough to do this (done these in Oracle many times), but I don't know the quickest way to export a row of data from a stored procedure to a text file. Isn't using a command-line shell too slow? What are my options?
