I want to use sql server as a back end for my asp.net shopping cart using vb.net..i have created an "news.mdf" under app_data folder of my website in visual studio2010...but i tried to connect it to database using below command...but showing error...
Hi there, I have inherited a databse and am building a new website to go wiht it. There is a file upload page which will upload images to a directory. I need to insert into the database retrieve the id just added then upload the image renaming it in the format locID(QueryString)_ImageID(retrieved from database).jpg The page has a file upload control and a button. I am trying to write my code behind so that when the button is clicked it inserts location id into the images table retrieves Image id. Renames the file and uploads it to the images folder. II think i need to call the routine from another routine for the button click but the signatures are different, where am i going wrong? or for that matter have i been pissing into the wind for the last 4 hours?

Hi everyone. Does anyone know if you can retrieve truncated data from a BULK INSERT operation?
We have a file that needs to be inserted into a SQL Server Database. There is a field that has a maximum of 8000 characters, but some times users submit files that have more than that. We need to be able to capture the truncated data. The BULK INSERT operation does not throw an error. The only way I can think of to get the data is if I bulk insert the data into a temporary table with a memo field and then copy it over, but that may really slow down the SP.
Has anyone encountered this situation before? I also have the option of parsing the file in .NET.
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.

I need to retrieve data from a flat file and load it to a database table. I know how to do that. But what if I want to retrieve 3 fields from another table for each row read from the flat file source based on a date from each row in the flat file data source.
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?
In a foreachloop, I am inserting records into a flat file which is working fine. But the thing is that as the file grows, it takes longer for it to locate the EOF(End of File) of the flat file so as to insert the records.
I have around 70-100 lines written to the file at each loop and there are more than 20k records to be looped. wihich means that at the end I should be having 1400k - 20000k line in the text file.
One solution would be to insert the records at the start of the file itself so that it does not has to lookup the EOF each time before writting.
Another would be to generate separate files and then merge it.
Any idea how can this can be done?
Beside this I have to zip the file and then SFTP to a given address.

Is it possible to actually insert a file into the email sent via sqlmail/ I ask cos when I try to send the results of a query via SQLMail, the formatting is shot. I want to automate a job to actually run a query, capture data to a file and then email the results to my users. I can get to the stage where the file is available, but then I'm stumped. Any Ideas please.
Hello. My application reads one file with more or less than 80 000 rows(like 09905003101399800464520220080408710200070050000020 90604500012000 ) Based on the index of each character the row is splited in 8 columns and then i must verify that 5 of this columns are not allready in the database... if they are the row is a duplicate and will not be inserted.
Wich is the best way to do that? To make 80000 cals to the database or to send the file as xml to the database and after that to parse it ....... or if you know any other way it would help me very much.
In this moment i m using the 80000 calls method and it takes ~20 hours. Please advice.... any advice will be highly apreciated. Thank you.
I have the data of ACTTAB, APTTAB and etc, how to i export this data from SQL and insert into a text file??? this is the first time i need to do. as for the 2nd thing is that after export the data from SQL into text file, i need to import this data into mongoDB. So basically how to export this following data (ACTTAB, APTTAB and etc) into text file?
Hi, I´m trying to bulk insert files that looks like this:
aaaa,bbb,dddd, ccc,dfd,tghj,
each file can have up to 10 data fileds per line, and each file will have same number of data fileds in particular file, let´s say 3 like above. Second file could have let´s say 10 and that is maximum.
I read the file and insert data with fieldterminator in temp table from witch I insert data to other tables regarding some parameters inside.
Now problem is: Msg 4832, Level 16, State 1, Line 1 Bulk load: An unexpected end of file was encountered in the data file. Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error. Msg 7330, Level 16, State 2, Line 1 Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".
That is because I´m trying to insert 3 fields of data in temporary table which is made of 10 columns (It have to be 10 because next file could have 10 fileds of data). If the temp table has same number of columns like text file has data fields than it works.
What is solution for this problem? Can I bulk insert NULL in columns for which I don't have data?
I can also import each line of text file to one column (with delimiter inside) but than I don´t know how to insert that data to correct tables or even to one table but to seperate data fields to columns with fieldterminator which is , in this case.
I'm new to SQL and I would apriciate any help. Thank you
Hi, I was wondering which is the best way to read data from a txt file and insert each row into sql. OLE DB Command could be? It will be necesary to work with variables? My txt file will have a defined width (if it is necessary to know). I will have many rows with many columns. I have to map eah column from the txt file to it's corresponding column in sql server and insert data into it for each row. Thanks for your help!
(Newbie) Hi, I am trying to create in a session variable, the ID of the last inserted record. My reading suggests I should use Scope_Identity. I'm having trouble with the syntax/code structure. Also, is it good programming practise to directly assign the session variable e.g. "Session[var]=SqlDataSource.Select()"? The error I'm getting from my code below is "No overload for method SELECT takes 0 arguments". Thanks. Session["snCoDeptRowID"] = SqlDataSource1.Select(); <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT Scope_Identity" </asp:SqlDataSource>

I have a bulk insert situation that would be nice to be able to pull off. I have a flat file with 46 columns that are to go into a table. The table, I want to have a 47th column to be updated later on by means of a stored proc saying if the import into the system was sucessful or not. I have the rowterminator set as '"' thinking that would tell SQL to begin on the next row, leaving the importstatus column null but i still receive an error.
First of all, is this idea possible within this insert statement. Secondly, if so, what would be the syntax to tell the insert statement to skip that particular column. It is the last column listed in the table so it just needs to start on the next row after it inserts the last bit of data in the flatfile.
If this is not possible, is it possible to bulk insert into a temp table?
I am running a set of SQL statements on a SQL server, to insert flat file data into a SQL table. The flat file is already FTP'ed to the SQL server. I seem to be getting an error, which is possibly pointing to a permissions issue
The statements:
BULK INSERT [Jedox_prod].[dbo].[B_BP_Customer] FROM 'c:jedox_dailyjdcom4401.txt' WITH ( FIRSTROW = 2, MAXERRORS = 0, FIELDTERMINATOR = '|', ROWTERMINATOR = ' ' ) GO
The error is : Msg 4861, Level 16, State 1, Line 1 Cannot bulk load because the file "c:jedox_dailyjdcom4401.txt" could not be opened. Operating system error code 3(failed to retrieve text for this error. Reason: 1815)
If it is permissions issue, how do I overcome this?
I just wanted to insert only SubjectIds into my table 'Subjects' which has the follwing schama ignoring the classes The row delimeter is " " and the column delimeter is ' | '
Table Subjects {
ID (Autoincrement) SubjectId varchar(20) }
Can any one provide the format file for doing this or suggest anyway to do this? Please do note that the file may contain millions of records
USE TEST GO /****** BULK INSERT ******/ BULK INSERT [Table01] FROM 'C:empdata.csv'
[code]....
I am using above code to insert csv file data which consist of arabic data as well.

With "bcp MyDatabase.dbo.MyTable out C:MyFile.Dat -n -T" command line, I could get an exported data file. And I can also import this file into MyTable using 'BULK INSERT MyDatabase.dbo.MyTable FROM 'C:MyFile.dat' WITH (DATAFILETYPE='native');' query statement.
Now, I want to make my own data file just like made by bcp above. Although I could make file of 'char' type, 'native' type file is needed for performance and other reasons. And the format file should not be used.
Hi, I have a data file and the contents of it are as follows
2 -- This is the header indicating the no of records in my files 1001|s1 1006|s2
The content of format file is as follows. This is to skip first column of the all the rows and get only Subs (i.e s1 and s2 )
9.0
2 1 SQLCHAR 0 100 "|" 0 ID ""
2 SQLCHAR 0 100 " " 1 Subs ""
Here is my query to get all the Subs from my data file
SELECT * FROM OPENROWSET( BULK 'datafile.txt',
FORMATFILE = 'FormatFile.fmt',
FIRSTROW = 2 ) AS a
But this query retuns only s2 where i was expeting s1 and s2. The reason being is that the firts row i.e header doesn't follow the format Can any one please let me know how to skip the first line in the data file and get the result as required
I have a table with an Identity column. Is there a way to get the automatically generated primary key after I insert something to the table? If so, what is the syntax?
Hai Everbody, for me in my project i want to read data from a csv file and insert it in a sql server databse table.The csv file may contain n number of columns,but i want only certain columns from that, and insert it in the database table.How to achieve this. Plz help me it is urgent. Thanks in advance. Thanks and regards Biju.S.G
I are using a BULK INSERT to insert the data from a ascii file to a sql table. The table has a ProductInstanceId column that exists in the tables but does not exist in the ascii DICast data. I am setting the ProductInstanceId to a Guid that will be used for Metrics. I would like to create the Guid in C++ and then set it somehow during the BULK INSERT DICastRaw1hr and DICastRaw6hr. I am calling the BULK INSERT from C++/ADO. I do not see how you can set a static data in the BULK INSERT for a column that exists in the table but does not the source data ... seems there should be a way to do this with the format file?
The other way to do this is with a TRIGGER. I have the TRIGGER below. Prior to the calling the BULK INSERT using ADO I will use ADO to ALTER the TRIGGER with the new Guid. When the BULK INSERT runs the ProductInstanceId will be populated with the new Guid.
ALTER TRIGGER DICastRaw1hrInsertGuid ON Alphanumericdata.dbo.DICastRaw1hr FOR INSERT AS UPDATE dbo.DICastRaw1hr SET ProductInstanceId = '4f9a44eb-092b-445b-a224-cc7cdd207092' WHERE modelrundatetime = (select max(modelrundatetime) from Alphanumericdata.dbo.DICastraw1hr(NOLOCK))
More Questions:
- The Trigger is slow. The Bulk Insert without the Trigger runs in about 10 sec ... with the Trigger in about 40 sec. I tried to use the sql code below in the TRigger but it was only doing the UPDATE on the last row. The TRIGGER must run after the BULK INSERT is complete. Now I am using the select (bad). Any comments ...
ALTER TRIGGER DICastRaw1hrInsertDate ON Alphanumericdata.dbo.DICastRaw1hr FOR INSERT AS DECLARE @ID as integer SELECT @ID = i.recordid from inserted i UPDATE dbo.DICastRaw1hr SET ProductInstanceId = '4f9a44eb-092b-445b-a224-cc7cdd207092' WHERE recordid = @ID
- I understand that I could set the Guid in the Default Value part of the table definition using the NEWID() function. I need the Guid to be the same for all the rows that are inserted during the BULK INSERT (all have the same modelrundatetime) ... how would I do this?
