View 2 RepliesI have been tasked to do the following using SSIS.
We received two csv files each week and we would like to load these files to two different sql server tables using SSIS.
These files should be archived into a folder after each load.
How can I achieve this?
how do you load the multiple flat files to into destination dynamically?
View 9 Replies View RelatedHow to download files from a webpage before loading into SQL Server tables? I have the following URL and under the Downloads & Resources section, I have different file formats.
By doing hover on the download tab for each file type, I see that there is a link that is associated with it just like the following:
For CSV - [URL] ....
For XML - [URL] ....
The above is just an example for your reference/understanding. In the sample data from the internal website I have, I need to do a similar operation. The only difference would be that I would be having multiple XLS files with a description for each.
Example:
Sales Q1 - <xls download tab>
Sales Q2 - <xls download tab>
Sales Q3 - <xls download tab>
Sales Q4 - <xls download tab>
<li>
<sub>Sales for Calendar Year 2015--All Countries </sub>
<a href="/Data/Downloads/Documents/Sales/Sales_Quarter1.xlsx">
<sub>[XLS]</sub></a><sub> , <a href="/Data/Downloads/Documents/Sales/Sales_Quarter1.pdf"><sub>[PDF]</sub></a><sub></sub></sub>
</li>
I need to download the file based on the month/quarter every time.
I have to load data into destination table, it has foreign key relation to two different tables called person table and organization table . sample data to be loaded is like
person_id organization_id
1 Null
2 NULL
Null 1
null null
person table and organization table doesn't have null values in them, when I try to load this data none of them are laoded, I know either person_id or organization id having null value is failing foreign key constraint. But I want to transfer all the rows except the ones having both nulls. how this can be achieved ?
I have a simple package to load data from sql server db into a flat file. I have a date field in the source data base (data type DATETIME) when i open the csv file some show the exact time stamp and some records show just the seconds like (00:00:0.7). I used CAST CONVERT bu still the same issue.

I am facing an issue that Data flow task failing after loading 29000 rows out of 2lakhs rows.
I am loading data from .csv file to OLE DB Destination.
This data flow task is placed inside For each loop container.
is this issue because of any performance issue in SSIS packages such as buffer size.
find the error below:
DFT Load Data from FlatFile:Error: The conditional operation failed.
DFT Load Data from FlatFile:Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR.
The "DER Add Calc Columns" failed because error code 0xC0049063 occurred, and the error row disposition on "DER Add Calc Columns.Outputs[Derived Column Output].Columns[M_VALUE_NUM]" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.

I set up a connection file in order to move data from sql to csv files. I should be at the last step, the data flow. but:I don't see any flat file in my destination assistant.
View 23 Replies View RelatedI 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 loading data from a sql server table into a flat file. The flat file connection manager has the following settings
GENERAL:
Format:Delimited
Text Qualifier:"
Header row delimiter: {CR}{LF}
Header rows to skip : 0
Columns:
Row Delimiter: {CR}{LF}
Column delimiter: comma(,)
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?
How do I add only new rows to a destination table (when copying a table from another database every night) ?Every night I am copying a number of tables from one database to another.I only want to insert news rows (that are not in the destination table, but are in the source table) to the destination table.I might normally drop the destination table and just copy over the whole table, but in this case rows can be deleted from the source table, but I want to keep these old rows in the destination table (to maintain history). So I only want to add in rows to the destination table that have been added to the source table since last time.I guess I could copy the whole of the source table to a temporary table in the warehouse, then use a T-SQL merge command to compare and just add new rows to the destination table- but suspect that this is not the best way.

View 5 Replies View RelatedI have a SSIS package that transfers data from three SQL Server 7 servers to a SQL Server 2005 database. This package has about 30 different tables it copies. The table structures in the source database and destination tables are identical. About 25 different tables load without any issues. I have about 5 tables that load some nights without a problem. On other nights, the data transfers seem to randomly (though usually the most recent records) ignore some of the data. I have logging turned on and receive no errors. It just appears to stop loading data.
I should also mention that I truncate each destination table before begining and each table is loaded from data from each of the 13 source database (I am combining data from 13 regional database for reporting purposes). This is done using a Foreach Loop Container that updates the Server/Region connection string for each region. I am using the OLE DB Source connection to the SQL Server Destination. I have tried as well with the OLE DB Destination with the same result (and no error). I do not do any manipulation to the data on the transfer, but added a "RowCount" transformation between the source and destination and it gives the correct number of rows, but not all the rows get loaded.
I got a flat file like:
Location CurrencyRates
ALBERTA #15U.S.$ 0.2930 1 Can$ 0.0900
BRITISH COLUMBIA #14U.S.$ 0.6891 2 Can$ 0.2117
MANITOBA #18U.S.$ 0.4557 3 Can$ 0.1400
If there a way I can use SSIS to transfer this file to something like:
locationUSDUSDrateflagCADCADrateALBERTA #15U.S.$ 0.29301Can$ 0.0900BRITISH COLUMBIA #14U.S.$ 0.68912Can$ 0.0900MANITOBA #18U.S.$ 0.45573 Can$ 0.1400
I'm doing a group by in an aggregate transformation. I have say 6 columns in the output and I'm grouping on all of them - how can I get duplicate rows in the output? If I do the same select and group by in SQL on the source data I don't get any duplicate rows. In fact out of 6000+ rows I only get 2 duplicates.
View 7 Replies View RelatedI want to load flat files into a single table. But the flat files can have variable number of columns upto a maximum of 10 columns. The table in my database has 10 columns in it. So in case if I load a flat file having 6 columns then rest of the columns in the table will have nulls. I don't want to use script task for this as I am not good in writing C#code.

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
I am running my package in sql server 2012, in which i am giving network path for flat file destination. And its working fine. But if i give m local path, its giving me error " cannot open data file" ...
Nothing is wrong with package.
Here's what I want to do -
Dynamically load a flat file from a dynamic source table-
The source table metadata is known via the SYSOBJECTS and SYSCOLUMNS tables- I can pull the column names, type and lengths from these tables based on the table name. (my goal is pretty simple- pull data from a table in our database, and save it down to a flat file)
Would this be enough to dynamically create the destination flat file? If so, how do I do it?
Thanks

Here's my delema, I have a file that's 308 bytes wide by 5.7 million records. The record length is fixed and the position and width of the known within the record. When I run DTS I recieve this error Msg MS DTS flat file provide and Err Diesdription: error creating file mapping view: not enough storage is available to process this command. Then when I try to continue with the wizard, it will not allow me to separate the data into the format that I need. Is there any other way to import this file using DTS?
View 1 Replies View RelatedHi. As the title, I am try to figure out how to write script to prevent duplicated rows before loading data from couple csv files to the OLE database table.
Another quick question, when I use Data Conversion to convert data from string to datetime or decimal type, it always return error like potential data loss.
I tried to load a fixed width flat file with around 300,000 rows. However, only the first 8xxxx rows were loaded to the destineation table and the rest row were loading blank records. There was no error message showing during package execution. I've tried to split the file in half and the result was the same. So it wasn't the data file problem.
Would there be any buffering issue I need to cater for inside the package? Thanks!
I have multiple xml data file in a directory say C:XMLData abc1.xml, abc2.xml, abc3.xml etc.
Need to loop through each file in ssis with Foreach loop container, and get the file name say abc1, and load the data of abc1.xml to abc1 table in sql server DB.
Next iteration will pick up the abc2.xml and find the abc2 table in sql server DB then insert the data in abc2 table.
While each iteration, xml source should also point each xsd file correspondingly.
Tables are already created in DB
I solved my problem up to getting the file name from ech iteration and assigned file name to variable, in oledb destination data access mode I select Table or view name variable, then corresponding table will get selected for data insertation.
Just wanted to know how can I read each xsd file for each xml data files while iteration.
I have one excel sheet contains 50 sub sheets with different names on it. Is it possible can i load all sheets into SQL using SSIS?
View 2 Replies View RelatedIn the FLAT FILE source, I have to find the duplicate rows based on the two fields say, "bill number" & "invoice date".
The rows within flat file has like "bill number" which is duplicated on the same "invoice date".
If duplicate rows found then move the duplicate rows into another Flat File.
If not found then move the rows into Sql Server Table.
Pls provide the solution. Thank you
Hi,
I have a data task with the following requirements:
1) Run query against database to retrieve rows
2) Add header and footer row to the result set. The footer row must contain a count of the records.
3) Write the rows to a fixed width file if there were any data rows
I have got to the point that I can create the file (using a set of tasks that includes derived columns, sorts, aggregation and merges). However the file is created regardless of whether there were data rows returned.
I can't check the row count before proceeding as this isn't set until the data task ends. And if I try to split them into separate data tasks (so that I can access this variable and perform conditional execution) it becomes harder to access the original rows.
Do you have any recommendations on the best way to achieve this?
It all seems to be very complex and I'm starting to feel that it would be easier to do this outside of SSIS...
Please help me to keep the faith!
For those interested this is a slightly simplified version of what I have so far (all within a single data task):
1.Run dummy sql to create header row 2.Run main SQL to retrieve rows
| |
| 3.Multicast
| | |
| | 4.Create footer row by doing sum() in aggregate task
| | |
| 5.Merge body and footer
| |
6. Merge header with body and footer
|
7. Create fixed width file
I am new to SSIS....
I have a very simple package that has a flat file source object and an ole db destination object in the data flow. All works fine.
If I change a row in the flat file to make it fail how do I make the program continue and go to the next row?
The ole db destination does not have a Error Output properties like the flat file source does.Thanks
