i have flat files in some direcotry. each flat file contains around 60,000 rows of data. earlier we were using excel sheets to upload data. but now the challenge is it is taking more time to upload data into DB tables. which is the best way to upload such a huge data into db tables. can we use SSIS for uploading data. if so, how can we achieve that.
View 1 RepliesI have a flat file with text that has a special character like this: "RIBA® Generic Strip Labeling." so the registerd symbol is coming as square when i am simply reading the file in c#. is there a way to read the symbol as is and print on screen? i am working in on a console application. Also other german characters, not all but a few are showing as squares as well.

View 1 Repliesretrieving data from sql server 2000 database which has four tables. 3 of them has 256 datafields. And I need to retrieve all columns from all table for last 3years. All tables are related through a coman primary key.
So, Total data is 300,000.
I am looking at upgrading a realtime program ASP.NET C#, that takes very frequently updated data and moves it from one database to another.
Currently using a middle man app, that pulls from one and inserts into another using SqlBulkCopy.
Is it better to have the source db server write a flat file and the middle man collect from that flat file?
I'm using a log file to document info while getting and processing info from a form
1. if not post back, open the log file, build page, send form. 2. get submit back from form, possible post back if errors, possible writes to log file, if no errors definitely writes to log file, and send confirm page. 3. postback from confirm page can either be going back to form or finalizing, and send acknowledge page, then done.
so I need to keep the logfile object between direct postbacks to the form, or posting back to orignal form page after gettting a postback from a confirm page.
this type of file setup works fine, it creates a single log file per day:
[Code]....
then successive writes are like this:
[Code]....
when the form submit comes back from the original send/submit, lf from above is 'nothing'
saw the post about 9 ways to maintain state, not sure at all which would be most appropriate to keep the lf object accessible between possible postbacks and submits to the form.
I am working on an SSIS package that needs to read a flat file and load the data into a SQL table. The problem is, the flat file name changes because it incorporates a date similar to this:
fileName_2010-04-12.txt
I found this site that shows how to set up a dynamic flat file connection:
[URL]
I understand the principle, but what I'm struggling with is using it in my data flow task. I need to configure the column mappings. In the PROPERTIES of the flat file connection, under expressions, I set up a ConnectionString with the following:
@[User::DataLoadDir] + @[User::priceFileName]
where [User::DataLoadDir] is the path where the file resides and [User::priceFileName] is a variable that should have the name of the specific file I want to read.
However, when I try to set the column mappings in the flat file connection, it's pulling the column headings for a different file in the same directory.
I have to get input from user in flat file format.then convert it to xml. Then, i have to store the entries into a datatable in the database. say 1,2,3 a,b,c be the user entries. it shall be stored into a table with 2 columns.how to do this?
View 1 RepliesI know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?
View 8 RepliesI am trying to export images from my SQL server to SSIS's Flat file destination but keep getting the same error: Error 0xc0208030: Data Flow Task: The data type for "input column "image_full" (105)" is DT_IMAGE, which is not supported. Use DT_TEXT or DT_NTEXT instead and convert the data from, or to, DT_IMAGE using the data conversion component. (SQL Server Import and Export Wizard) The data type is IMAGE in SQL DB. I would like to export the image and save the same in local folder. Is their any way to perform this task using SSIS flat file destination? What is the best and easiest way to do this? What format should I be exporting to?

The only things I need from this are:

and the rest of the information I can discard. A customer uploads this as a .csv file (even though it really isn't as you can see) and I'd like to parse the needed information and post that to my SQL database and discard the rest. I think I can do this with a dataset but I've never built that before. The fields from the customer will always be the same and the fields I will need will always be the same. Also, the date time has to be in the format of yyyy/mm/dd:hhmm and the phone number always has to have 512 as a prefix. Here is the code I currently have for my site:

1) I need to make reading CSV file from the fileupload and then retrieve the data.
2) I need to load CSV and the 3 columns rise two functions.
Load CSV data and then stored in a database, but I need to save storage space vary according to 3 column.
CSV Example:
1 column - Cat, 2 column - Black, 3 column - 1
1 column - Dog, 2 column - Brown, 3 column - 2
1 column - Cat, 2 column - Black, 3 column - 1
1 column - Dog, 2 column - Brown, 3 column - 2
Now I need to load the CSV in C # and column 3 to distinguish what the operation is carried out.When the load line in column 3 contain the value 1, so will save the table 'Cats' when the value 2 and is saved in the table "Dogs".(Note: Data are separated ";")

I would like to find a way to read a txt file (in my case delimited by ¤). I need to change the order of the columns and also add and remove some columns. My output file should be a txt file delmited by ;.

This does not me since I´, reading the txt file from start to end and my output will be the same. It does not seem like I can have a custom sql statement when reading the file.
