I have a simple data flow task. It's a OLE DB Source to Flat File Destination setup.
One table, one column. Everything works great except there is a trailing comma (column delimiter) in the flat file when I'm done. Why is it putting an extra delimiter after the column as if there were another column?
Output
dog,
cat,
camel,
moose,
How do I get rid of that trailing delimiter?
Are you sure the row delimiter is not also a comma

I have this SSIS task, I read the contents of a CSV file and then I insert into a table
In one of the columns I should perform a trim in the values before inserting them in the table, how can I modify the csv before the insert?
Add a Derived Column transformation in the data flow between the Flat File Source and the ADO/ODBC/OLE Destination there.
If you want to trim, then you need to apply both a left and a right trim operation. I favor creating new columns versus renaming existing as I find it's easier to debug.
Assuming I have an inbound column named Col1, I would define a new column called Col1_Trimmed And remember that SSIS column names are case sensitive
LTRIM(RTRIM([Col1]]
Caveats about what is whitespace in the documentation for LTRIM
We receive a flat file that is delimited from our third-party client.
Row Delimiter = LF;
Column Delimiter = Tab
The file has 8 columns.
The delimited formatting in the file is correct for the most part except for three records where the 6th column splits and the record continues into the second row. There are two tab column delimiters after the column breaks into the second row.
We use SSIS to insert the records from the file into our DB and the ETL breaks because of this inconsistent formatting.
We had to manually tweak the column so that the job runs successfully.
Is there a way to correct the formatting issue in SSIS? I need help with writing a parser to correct these abnormal records in the file before inserting them.
Normal Row:
Problematic rows:
To fix the file structure, you should read each row as one large column DT_STR (4000). Then you should use two script components: the first one to fix the erroneous rows, and the second to split each row into separate columns before inserting the data into the destination database.
You can check my answer on the following question for a step-by-step guide: SSIS reading LF as terminator when its set as CRLF
Alright so I am not sure how to go about this, I have files that will be coming in a format like this that I need to read into a SQL Server database:
As you can see, it is "~" delimited and it contains no columns names at all. I will have multiple files like this incoming every couple of hours and I have the entire SSIS set up ready besides the part where I actually need to read the data because I am confused on how to handle this delimiter format that other department came up with.
As you can see if I specify the column delimiter just to be "~" it works fine
until it reaches that point where the row ends at which point there is this unnecessary row of "~" that starts and it confuses the connection manager into thinking these are separate columns, creating a bunch of empty columns
I can't simply delete all empty columns because some legit columns can sometimes come in as empty. The only mediocre solution I found so far is to go to advanced options in file connection manager and manually delete all of the columns I don't need. But the reason this will not work at all is because next file I will get might contain more rows than this one and it will still think that "~" after every data row is a column delimiter when in reality it is just a row separator. The number of columns however will always remain static in each file.
We have an SSIS package to import data from CSV flat file to a table on SQL Server. The file consists of several hundred lines of data that are delimited by a comma(,) with text data qualified by double quotes ("), but not all the text columns are qualified by double quotes. The problem arises when a string that is not qualified by quotes (") contains comma (,). This cause the package to fail with following error
[Source Data [130]] Error: The column delimiter for column "ColumnX" was not found.
I tried to redirect the bad rows to another flat file destination, but the package is not redirecting the bad rows, but its failing
If you can't get whoever generates the file to fix it, your only programmatic solution is to write a script task that fixes the file before it goes to the dataflow.
The script would need to analyze each row to see if it has the right number of commas, and to add quotation marks around the fields. If it finds one with too many commas, it would have to apply some logic (which only you can determine) to decide which comma isn't a column delimiter and make sure that comma is either deleted or enclosed in the quoted field value.
Using SQL 2008 R2, I've created an SSIS Package that rips through a flat file and imports them into a SQL table.
If any record in the data file does not contain all the required fields, that record should be skipped in the import process. All skipped records should be emailed to me when the package completes.
Here's the data file structure:
123|ABC|Y|Y
784
456|DEF|Y|Y
789|GHI|Y|N
812||Y|N
...
So, in this scenario, I would want the 1st, 3rd, and 4th record to be imported, and the 2nd and 5th record to be skipped and emailed.
I tried testing this out as is, and since it looks for a pipe delimiter, it reads the second line together with the third as:
784456|DEF|Y|Y
I'm about 3 days old working with SSIS, so if someone can assist me in accomplishing this task, I'd be grateful.
How big are the files? One way, is to use a staging table. NOT a temporary table.. The staging table is a physical table that retains its existence in the database. You dump all records there, then insert the good data into the production/main table, then export the bad rows into a file which you can append to the sendmail task..
(then you can truncate the staging table for the next interval/run/loop/file)
Another way would be to use conditional splits, and then set each row to a variable which then has a format applied to it, appending a delimiter other than a pipe, then into the export file.
Since it's merging the second line with the third, it sounds like either the row delimiter is incorrect on line 3 or it's not set correctly in the connection manager. I'd take a look at the file in Notepad ++ (or a text editor that will expose hidden characters like Cr and Lf) and verify that the row delimiter is consistent for each row and that it matches what's been set in the connection manager.
Once the row delimiter issue is straightened out, you can separate the erroneous records with a conditional split. Under condition, type [YourColumnName] == "" and under Output name, type Error. Name the default output name "Correct". Now map the "Correct" output to your table and map the "Error" output to a flat file, script component, table, or whatever format you want the errors to go to.
