Integration Services :: Don't Write Flat File Destination If Conditional Split Is Not True
May 8, 2015
I have a Problem with my destinations. I have a split condition with two ways the flow can use.
In this case: all and Date.
All and Date can be set by using a variable. Its working good.
When a user fills the variable with a date value (cast to string) the conditional split executes the correct flow with all the needed rows... The same time the all flow will be executed with 0 rows. In the end the destionation file for the all values will be overwritten with nothing. The same on the other hand when a user fills the variable with the all value, the date file is empty. What can i do to make sure that the files are not empty?

Hello everybody
I have one question about deleting blank row on flat file destination from conditional split.
I create an SSIS package to filter data from Flat file source.
On flat file source, it is Ragged right format and header row delimeter in {CR}{LF}
the coulums are devided manulaay using markers.
I use only 2 columns divided and send the source into conditional split task and the conditions are given to filter data,
when the output from conditional split is placed on flat file destination, i notice blank rows on the output. I want to delete the blank rows so the result data can be displayed continuously in rows.
anybody has any idea for this? I know the script task will work but hope to avoid to use script task.
Thank you in advance for all the help.

Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
@[User::Output_Path] + "Comms_File"+ @[User:: FileNumber] +"_" + replace((DT_WSTR, 10) (DT_DBDATE) GETDATE(),"-","")+ ".txt"
All this successfully creates these 4 files:
Comms_File_1_20150724.txt, Comms_File_2_20150724.txt, Comms_File_3_20150724.txt, Comms_File_4_20150724.txt
Now the QUESTION is how do I get these filenames as I need to insert them into a DB Audittable. The audit table looks like this:
CREATE TABLE dbo.MMMAudit
(
AuditID INT IDENTITY(1, 1) NOT NULL,
PackageName VARCHAR(100) NULL,
FileName VARCHAR(100) NULL,
LoadTime DATETIME NULL,
NumberofRecords INT NULL
)
To save the Filename & how many records in each file in our Audit Table, am using an Execute SQL Task and configuring it as this:
Execute SQL Task
Parameter mapping - Mapped the User Variable (RecordsInserted) and System Variable( PackageName) to Insert statement as shown below
SQLStatement: INSERT INTO [dbo].[MMMAudit] (
PackageName,NumerofRecords,LoadTime)
(?,?.GETDATE)
Again this all works terrific & populates the dbo.MMMAudit table as shown below BUT I also need to insert the respsctive file name – How do I do that?
AuditID PackageName FileName NumberOfRecords
1 MMM NULL 12
2 MMM NULL 23
3 MMM NULL 14
4 MMM NULL 1

Import.csv file looks like,
TABLE_NAME DESC CODE
tab1 table1 A
tab1 table1 B
tab1 table1 C
tab2 table2 D
tab2 table2 E
tab2 table2 G...
First column values are table names which are already exists in target database. Next two columns[Desc],[Code] data gets populate from CSV file to table.
In this scenario, how to load tab1 data into the same table in destination and so on.
Which way will be more standard to accomplish this task? If its a script task using C#, looking for clear script to identify a value changes in the first column.

I have a SSIS job which takes a SQL Server view as its source and outputs a flat file. The file is quite large, about 20000 rows of 30 columns and up to 400 characters per row. It is configured with CRLF at the end of each line, tabs between columns, and no header row. Most rows are output with no problems, but occasionally a line will include a line break (CRLF) in the middle. The problem appears random, but the rows with spurious CRLFs appear in clusters, with each row in the cluster having a line break after the same column. To illustrate, it looks something like this:
col1 col2 ... col 30
col1 col2 ... col 30
col1 col2 ... col 24 CRLF
col25 col 26 ... col 30
col1 col2 ... col 24 CRLF
col25 col 26 ... col 30
col1 col2 ... col 30
col1 col2 ... col 30
So although there is some pattern, where a group of lines will include a break in the same place, I've not been able to identify the pattern and relate it back to the data items.
What could possibly cause CRLFs to spontaneously appear midway through the row?

I'm trying to write a conditional split where I want to bring in only records where the date is less than today, but my problem is that I can't simply do this Column < GetDate() because if something comes in today, it takes the time into account and it will bring that record for today. You can do this in SQL, but I'm not sure how to do that in SSIS
SELECTCAST(CONVERT(char(8),GetDate(),112)ASdatetime)

I'm encountering a very peculiar situation when I'm trying to compare source and target data using conditional split. Following is the Data Flow and how I'm trying to achieve this.
Source Data : Col_A (PK) Col_2
1 100
8 500
Target Data : Col_A (PK) Col_2
1 100
3 700
8 500
Look-up Target on Col_A to check for existing records. Now we have four columns in Look-up match output: Col_A, Col_B, Lkp_Col_A (Target Col), Lkp_Col_B (Target Col).
Conditional Split: Compare Col_B with Lkp_Col_B
Update target if there is any change in the existing value of Col_B.When I'm running the package for every record in source, the conditional split fails and even when there is no change in Col_B, some of the records (Not all and quite randomly) get updated with the same value. If I run the package for few records, it works absolutely fine.

I am importing the values for field Atype from a .csv file as DT_STR, 13 and I need to fit them into a bit type CType field.
When I write the conditional split ((ISNULL(Atype)?"a":Atype)!=(ISNULL(CType)?"9":CType)) it says that the DT_WSTR and DT_I4 types are incompatible and that I need to explicitly cast with a cast operator. I haven't been able to make it work, how to explicitly cast?

I have a ssis package where I need to have excel destination. In the Excel file, I need to have few rows with some text and then populate data below the text. One the text is like this:
Data as of: 08/25/2015
if the report ran today, then Data as of will have Yesterday. So, if the user opens that excel file after a week, then user should see same Data as of: 08/25/2015. not today()-day(1).
I was planing to handle on excel side with today()-day(1). but it only works the day it was run. Then the excel file is open after few days later, then it might as Data as of: 08/30/2015 which is not true. It should still stay Data as of:
08/25/2015 on what ever date the excel file is open. The SSIS package runs only once.
How do I handle this so that whenever user open the file, they will see Data as of: 08/25/2015. This is not a column in excel. It is like a description of data in excel.

I have a package in which there are only one Data flow Task and it has only three components. 1) Source , which is a SQL db 2) destination and 3) OLE DB Destination flat file Error output file. I want the error file to be created ONLY if there is any error while dumping the data into destination DB. But , the issue is, the error flat file is being created inspite of No error while dumping the data from Source to Destination.

Is there a recommended file format (csv, xml, txt) when choosing a file destination for SSIS? Does a file format impact the performance in terms of loading? Let's say i have chosen to use a .csv as my file destination (this has 15million rows and 50 columns with 2 bigint and the rest binary(32)) and later on, i would need to reload them back to table using SSIS. Is using csv faster than e.g. xml when reloading? Does it have performance impact at all?

Hi,
I am testing SSIS and have created a Flat File Destination. I defined the Flat File Connection as New for the first time and it worked fine. Now, I would like to go back and modify the Flat File Connection in the Flat File Destination Editor, but it allows only to create a New connection rather allowing me to edit the existing one. For testing, I can go back and create a new connection, but if my connection had 50-100 columns then it would be an issue to re-create it from scratch.
Did someone else faced this issue?
Thanks,
AQ

I have been working on this import for days and I just can't figure this out. All I am trying to do is import a flat csv file into a new table using the default settings in the import tool and it just won't work! I have tried it hundreds of different ways, including saving the package and opening it in BIDS. I am new to SQL and SSIS... Errors are below.

I am transferring data from an OLEDB source to a Flat File Destination and I want the column width for all of the output columns to 30 (max width amongst the columns selected), but that is not refected in the Fixed Width Flat File that got created. The outputcolumnwidth seems to be the same as the inputcolumnwidth. Is there any other setting that I am possibly missing or is this a possible defect?
Any inputs will be appreciated.

I will be receiving a CSV daily where columns within the file will change. The column order and number of columns can change daily. I need a way to read in the header from the csv and create a flat file connection that reflects the columns listed in the header.
Is there an easy way to do this using a script task? I have already read the header into a table but I have been unable to create the dynamic file connection.

How to design ta SSIS package which loops through DESTINATION folder files and checks whether that file is there in the SOURCE or not.
If the file exists then I have to check the modified date on DESTINATION file if it is greater than 1 day delete that file. If the modified date is less than that SOURCE file then I have to copy that
file to DESTINATION<o:p></o:p>
<o:p></o:p>
If there are files which exists in SOURCE and not in DESTINATION, then how shall we copy all the files to the DESTINATION that are created on the day of execution of package.<o:p></o:p>

I have a delimited text file with 650+ columns. The sum of the column lengths of a single row, if fully populated, exceeds 30K bytes. The "killer" fields lengthwise are the "Description" fields. If they were removed from the input file, the remainig columns would occupy about 5000 bytes, which is within SQL max row length.
Can SSIS be used to created these two tables? (one without description fields, the other with those field but arranged vertically in the table rows).
The fundamental issue is I can not import a single file row into a sql table because that row length could exceed the max byte count for a row.

I am having difficulties loading data from a flat file to a SQL Database. I am able to load some data but the rest gets kicked out for the following reasons:
1 – The field is varchar 50 and I would like to convert it to a date field
2 – The field contain periods (.) (Only 1 period in each row)
3 – The field contain blanks (NULLS)
How do I create a derived column that will bypass blanks (Nulls) and remove periods (.) in each row then convert column to a date field in SSIS? Looking for steps to create a derived date column using SSIS (derived task); convert it to a date column (09-19-2015); use functions to redirect the nulls and possibly remove the period (.)?

Hi All,
I need to know how to create a AScii 7 bit flat file using Integration services. I do have basic charecters in the flat files - only other charecters required are a pipe (|), which is used as delimeter and additionally it will have line feed (LF) which is used as row delimeter.
Please let me know if this is possible.

Can we disable a flat file connection manager in a ssis package just as how we can disable a OLE db task? When I try to disable the flat file by clicking on work offline its gets disabled which is what i expected , but when i close the package and reopen it again its again enabled , is this the way that a flat file connection manager works.
