I have a flat-file schema that has a header and detail records. It looks something like this:
HDR**2401*XX0062484*22750***20081006000000*000*******
LIN**001*788-0538-001*4891-788538010*20000*EA**0000***
I need to append two blank lines at the end of the message. Right now, if I have multiple records I get the following output:
HDR**2401*XX0062484*22750***20081006000000*000*******
LIN**001*788-0538-001*4891-788538010*20000*EA**0000***
HDR**2401*XX0062484*22750***20081006000000*000*******
LIN**001*788-0538-001*4891-788538010*20000*EA**0000***
What I want to see happen is something like this:
HDR**2401*XX0062484*22750***20081006000000*000*******
LIN**001*788-0538-001*4891-788538010*20000*EA**0000***
HDR**2401*XX0062484*22750***20081006000000*000*******
LIN**001*788-0538-001*4891-788538010*20000*EA**0000***
I could build a custom pipeline component to do this, but I'm wondering if there is a simpler way of getting what I need?
You should be able to accomplish what you want by using the Delimiter properties of the flat file schema.
Based on your example file I created a schema with the following record structure:
<Schema>
<Root>
<HDRGroup>
<HDR>
<LIN>
If you click on the root node of your schema you should see a list of properties for this root node. One properties section has the header 'Flat File'. In this flat file section the first three properties you can set are Child Delimiter, Child Delimiter Type and Child Order.
This is where you configure the schema to create the blank lines (in this case CR LF but you can set different things as you need) For your example I set the following:
Child Delimiter: 0x0D 0x0A 0x0D 0x0A
Child Delimiter Type: Hexadecimal
Child Order: Infix
0x0D 0x0A is a carriage return line feed, so the above simply creates two blank lines, infixed between each child of the root node.
The <HDRGroup> then functions to make sure that each header and its lines is kept together. For its delimiter settings I set:
Child Delimiter: 0x0D 0x0A
Child Delimiter Type: Hexadecimal
Child Order: Postfix
The <HDR> and <LIN> records then contain the actual schema definition for your message lines, delimited with an asterisk.
This schema works for something that looks to me like what you have asked for - this sort of flatfile schema and how it parses a file is highly dependant of the little details, however, such as what type of line breaks there are and if there are line breaks at the end of the file.
The princples of using the delimiters will stand, you will likely find you need to tinker with the settings.
For anybody who cares, I finally caved in and wrote a custom pipeline component to accomplish this.

I have text file which is having ^(CAP) and ,(Comma) as a delimiter and after clearing i need to load to sql . I have tried my best to clear a source file
But still file is not cleaned as expectation .
Please find the below picture i have tried to correct the source file
But still file is not cleared as expected . Please find below uncleared file .
You have a variety of issues here.
You have identified the header row delimiter as a comma. A row delimiter is the, usually invisible, delimiter than indicates a row's worth of data has happened. Traditionally, this is an Operating System specific value but it's a Carriage Return (CR), Line Feed (LF) or Carriage Return/Line Feed.
Your source data is not a comma delimited file with caret/circumflex/cap text delimiters. You have a comma-space delimited file which SSIS doesn't support in the editor. However, if you hand edit the dtsx file as I outlined in How to read a flatfile with lowercase thorn as the delimiter to specify that it should use comma space ColumnDelimiter="_x002C__x0020_"
Given a truncated version of your source data
ListCode, CAS, Name
^216^, ^^, ^Coal Dust^
^216^, ^7782-24-5^, ^Graphite (Natural)^
^216^, ^^, ^Inert or Nuisance Dust^
and the comma (0x2C) space (0x20) edited into the raw dtsx connection manager, I was able to pull data as I believe you are expecting
You might also run into additional issues given your selection of code pages and not checking the Unicode button but that's beyond my ability to generate matching source data from an image.
Just replace the ^, ^ with ^,^
It looks like your source
CAS, SubName, ListCode, Type, CountryCode, ListName
^1000413-72-8^,^fasiglifam^,^447^,^Chemical Inventory^,^EU^,^ECICS Custom Tariff Codes^
^1000413-72-8^,^fasiglifam^,^0^,^^,^NN^,^SPHERA Global Substance List^
Then edit your connection manager with below details

It will work .

I am getting familiar with an SSIS solution and I just realized something that is new for me:
there is a foreach loop task which contains this information in the "Files:" box:
What does it mean?
Does it mean that the task will take the files with name like:
A(something)Sell(something)Depot(something).csv?
like: A10Sell123Depot21.csv
In the Files text box, The asterisk wildcard (*) mean that you don't know this part of the name.
`*` --> unknown string
`?` --> unknown character
Example:
"In the Files text box, enter File.txt. The asterisk wildcard () let’s us include any text file that starts with “File,” without having to specify each file. If our files had instead been Word files, we would have entered File.doc. If we were moving multiple file types, we would have used File*.* as our property value." Read More
So in your case, yes A*Sell*Depot*.csv means A(something)Sell(something)Depot(something).csv which will match A10Sell123Depot21.csv
I have a file that contains the following content (simplified version that demonstrates the problem):
"abc\"def"
I would like to load the literal content of the file into a table without any mangling of the data. Here is what I am currently doing:
CREATE TABLE file_content (content text);
COPY file_content FROM '/path/to/test.txt';
The resulting line in the table is:
"abc"def"
In other words, the backslash was silently dropped/ignored. I've tried the copy with different encodings (UTF8, LATIN1, SQL_ASCII) without any change in behavior.
Also, the ESCAPE and QUOTE options seemed promising at first, but they are only for COPY ... TO.
Is there a way to load raw data from a file without the mangling? I'm using version PostgreSQL version 9.4.6.
You need to change \ to \\. You can use sed for that:
sed -i -- 's/\\/\\\\/g' import.file
Please make sure you have reviewed your data and backuped it before performing operation above.
I have an input file that I want to use the string SPLIT function on for each line, depending on the Type field. However, the description field sometimes has data that has new lines in it so it messes up my file reader since it uses streamreader's readline() function
Handled:
Type|Name|User|Description
Type|Name|User|Description
Unhandled:
Type|Name|User|Description line 1
Description Line 2
Type|Name|User|Description
Besides not being able to validate on 'Type' for each line and keep reading the file for when the next Type field appears, are there any ways folks can come up with to properly read this file?
My solution was to have the file maker replace newline characters in their description field with another unique character that I can later add back in. I'm still interested in solutions from the file reader's perspective though
I know I'm talking to myself a lot here, but I found another solution, which is to remove remove line feeds, since the output file creator wrote out carriage returns for each line.
You could easily set a conditional statement to see if the Split array contains more than one element, which would indicate that it's a line you want to parse.
I need to parse a CSV file with blocks of text being processed in different ways according to certain rules, e.g.
userone,columnone,columntwo
userthirteen,columnone,columntwo
usertwenty,columnone,columntwo
customerone,columnone<br>
customertwo,columntwo<br>
singlevalueone
singlevaluetwo
singlevalueone_otherruleapplies
singlevaluethree_otherruleapplies
Each block of text will be grouped so the first three rows will be parsed using certain rules and so on. Notice that the last two groups have only one single column but each group must be handled in a different way.
I have the chance to propose the customer the format of the file so I'm thinking to propose the following.
[group 1]
userone,columnone,columntwo
userthirteen,columnone,columntwo
usertwenty,columnone,columntwo
[group N]
rowN
A kind of sections like the INI files from some years ago. However I'd like to hear your comments because I think there must be a better way to handle this.
I proposed to use XML but the customer prefers the text files.
Any suggestions are welcome.

Ps. using VB.net and VS 2008
You can use regular expression groups set to either an enum line mode if each line has the same format, or to an enum multi-line if the format is not constrained to a single line. For each line in multiline you can include \n in your pattern to cross multiple lines to find you pattern. If its on a single line you don't need to include \n also know as Carriage return line feed in your regex matching pattern.
vb.net as well as many other modern programming language has extensive support for grouping operations. You can use index groups, or named groups.
Each name such as header1 or whatever you want to name it would be in this format: <myname>
See this link for more info: How do I access named capturing groups in a .NET Regex?.
Good luck.
