flat-file

问题 I got only these 2 errors when converting flat files to database tables. The dataflow seems to work for other flat files with the same layout so I don't understand where these errors could come from. [Flat File Source [204]] Error: An error occurred while skipping data rows. [SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on Flat File Source returned error code 0xC0202091. The component returned a failure code when the pipeline engine called PrimeOutput(

问题 Have a pretty straight forward SSIS package: OLE DB Source to get data via a view, (all string columns in db table nvarchar or nchar). Derived Column to format existing date and add it on to the dataset, (data type DT_WSTR). Multicast task to split the dataset between: OLE DB Command to update rows as "processed". Flat file destination - the connection manager of which is set to Code Page 65001 UTF-8 and Unicode is unchecked. All string columns map to DT_WSTR. Everytime I run this package an

问题 Is there an easy or straightforward way in Java to output the results of a DB Query to a file (either csv, tab, etc). Perhaps even in Hibernate? I know that a query results can be dumped to a flat file on the DB Server. I am looking for a way that an application can run a query and get those results into a file. I realize one option is to just iterate over the result set and output the records one row at a time separating with a delimiter. But if there is a built in way, or a Hibernate way -

问题 This will be a bit of an update from the question I asked here before. I need to traverse folders & dump txt files to SQL tables with the same name (barring the .txt extension) My folder/file structure is setup as shown below Now the FileA,B,C are consistent throughout all the folders & there happens to be a [dbo].[FileA],[dbo].[FileB],[dbo].[FileC] etc sitting on the server. So Data1 Folder will have FileA,FileB...FileZ & so will Data200 Folder. The goal is to traverse through all the

问题 I am trying to create a custom pipeline component for BizTalk 2010 that splits an incoming flat file into multiple smaller files. I want to split the file (lets say of ~30 000 rows) into files of about 5000 rows each or a bit less (lets say if the file includes 33 000 rows). I have tried using Selvan's great example of a custom dissassembly pipeline to no avail. I have used the Pipeline Component Wizard to generate a pipeline skeleton, but would be very happy with any tips or pointers on how

问题 Has any one ever seen a backspace delimited flat file? My requirement is to parse such a file but I am not able to put a backspace character into a file to check if I am able to detect it. 回答1: Splitting shouldn't be any harder than using any other delimiter. It's just another character, after all. In Python, for instance: >>> x = "apples\bbanana\bcoconut\bthese are delicious!" >>> x.split('\b') ['apples', 'banana', 'coconut', 'these are delicious!'] Most languages use \b as the escape

问题 I have an SSIS package that converts a .csv file into an .xlsx file before being loaded into SQL. Is there a way to have a process that overwrites the current .xlsx file instead of adding data into the .xlsx that currently exists? 来源： https://stackoverflow.com/questions/34180563/ssis-package-csv-to-xlsx-need-to-overwrite-instead-of-adding-data

问题 I'm currently running Strawberry Perl on WinXP, and I'm trying to process a unix-formatted flat file. The flat file uses line feed characters to delimit fields, and form feed characters to delimit a record. I am trying to convert the FF to anything else (CRLF, ';', TAB, etc). I have tried using the following perl one-liners with no success: perl -p -e 's/\f/\r\n/g' < unix.txt > dos.txt perl -p -e 's/\x0c/\x0d\x0a/g' < unix.txt > dos.txt perl -p -e 's/\f/\t/g' < unix.txt > dos.txt The only

问题 This code below will import a tab delimited file with over 255 fields into two tables. Just make sure when you design your two tables all your fields have the correct data types for the fields being imported. I originally created my tables by using Access import text file wizard. Before using the wizard I deleted the fields after 255 to create the first table and then deleted the first 255 to create the second table. Hopes this helps someone and thanks to everyone below who helped me with
