I noticed something strange today. I created a pkg that reads a flat file and writes the rows to a table.
In checking the data in the file against what's in the table, I noticed that the rows were inserted in a different order than they are in the file.
All the rows appear to be in the table correctly, but they're just not in the same order as in the file. I've never seen this before. But I checked very carefully, and this is indeed the case.
I have a SSIS package that dumps data from an internal table to a flat file output using standard data flow tasks. The entire table is output - no special SQL. Most of the time the records are placed in the output file in the same order as the internal DB table, but occasionally the order appears to be more random. When that happens, the record order in the internal table is correct - it is just the output.
I can find no properties that seem to affect this. I would appreciate any hints and advice that anyone can give me. Has anyone else encountered this same problem?
I never paid much attention to this before but I noticed this today in a new table I was creating.
For tables defined in the tabular model the table properties have something like SELECT Blah FROM TableName ORDER BY Blah Then in the tabular model the table's data is in the same order it was ordered by in the data source for the table.
I have a date table I setup and I noticed it is NOT respecting the sort order.
I have it sorted by DateID which sorts with the oldest date first and newest date as last row.However, the table that is imported and stored in the data model is not in that order.
I can of course manually sort the rows in BIDS/DataTools, but I find this discrepancy odd.
Would this have negative impacts on the EARLIER function for example if the data rows are not in the order specified?
I need to create a number of flat files, all with the same layout and sourced from the the same table, but with different criteria.
The first set of (three) flat files file is created out of a simple Conditional Split transformation: If Source Table row number > 40,000 route to File 3; if row number > 20,000, route to file 2, otherwise route to file 1. This gives me 20,000 rows in files 1 & 2 and the remainder in file 3.
I also want to create a fourth flat file by joining the Source Table with a sample table and selecting only those rows where the Customer numbers match. I'm currently doing this in two stages: An Execute SQL Task performs the join and inserts the selected rows into a Destination table (identical layout to source table), and then a simple data flow moves the rows from the Destination table into the fourth flat file.
My problem is that the order of the columns in the first three flat files is different from the fourth file. I've tried creating the fourth flat file with a single data flow using a Merge Join transformation which didn't work because the tables aren't sorted in the correct sequence, and I couldn't get an OLE DB Command transformation to work either.
I'm not sure why the column order of the 4th file should be different seeing as how its contents are sourced from the same Source table, but is there a cunning way of setting this up so that the columns end up in the same order?
First, a couple of important bits of information. Until last week, I had never touched SISS, and therefore, I know very little about it. I just never had the need to use it...until now. I was able to convert my first 3 flat files to SQL2005 tables by right clicking on "SISS Package" and choosing "SISS Import and Export Wizard". That is the extent of my knowledge! So please, please, please be patient with me and be as descriptive as possible.
I thought I could attach some sample files to this post, but it doesn't look like I can. I'll just paste the information below in two separate code boxes. The first code box is the flat file specifications and the second one is a sample single line flat file similar to what I'm dealing with (the real flat file is over 2 gigs).
My questions are below the sample files.

As you can see, each entry could have any number of records and multiples of some of the record types, with one exception, every entry must have a "01" record and can only have one "01" record. Oh, and each record has a length of 400.
I need to get this information into a SQL 2005 database so I can create a front end for accessing the data. Originally, I wanted one line for each account and have null values listed for entries that don't have a specific record. Now that I've looked at the data again, that doesn't look like a good idea. I think a better way to do it would be to create 5 different tables, one for each record type. However, records 2 through 5 don't have anything I can make a primary key. So here are my questions...
Is it possible to make 5 tables from this one file, one table for each of the record types?
If so, can I copy the Account number in record 01, position 13-19 in each of the subsequent record types (that way I could link the tables as needed)?
Can this be done using the SISS Import and Export Wizard to create the package? If not, I'm going to need some very basic step by step instructions on how to create the package.
Is SISS the best way to do this conversion or is there another program that would be better to use? I know this is a huge question and I appreciate the help of anyone who boldly decides to help me! Thank you in advance and I welcome anyone's suggestions!
My OLE DB Source is getting data from the following column types:
ID varchar(50), Name varchar(100), Date datetime, Currency char(3), Cost numeric(30,10)
My OLE DB Source outputs my information in the following order when I click Preview:
ID Name Date Currency Cost
When I connect the OLE DB Sorce to a Flat File Destination, it comes out in the wrong order.When I examine the "line" between them (Data Flow Path Editor) I get:
Currency DT_STR Length: 3
ID DT_STR Lenght: 50
Name DT_STR Lenght: 100
Date DT_DBTIMESTAMP
Cost DT_NUMERIC
What is the easiest way for me to change this so the Flat File Destination will output my data in the same order as the OLE DB Source:
I build my SSIS package based on the above file.But now i receive files with different columns order let say
lastName,FirstNamr,Address l1,f1,a1 L2,f2,a2 or Address,FirstName,LastName a1,f1,l1 a2,f2,l2
every time i receive multiple files in different order and i have to remap all my mappings. These are just a few columns and i have like 20 columns and the order can potentially change any time. so every time i have build new packages remap them etc.
through normal c# code it pretty easy. I tried to add script here but the script also needs a source and mapping so there is also a mapping issue. Is there a better way to do this.
I have rows in a table in a SQL Server 2005 that I want to send to a Flat file. When I am executing the task for the first time it is OK and works perfectly. But the problem is when I am trying to do it again. I seems like the path to the file and the filename dissappears after the first time and the execution failes with an error message that tells me that the file is invalid and donīt exists.
I donīt now why this is happening and itīs such an easy thing to do and I canīt make it work.
I have a text file that come from our client that is Column deliminated by ~ and row deliminated by {CR}{LF}. There is a comment field that appearently is not cleaned up and has {CR}{LF} within the comment field.
I am new to SSIS and I'm wondering if there is a way to detect and correct the bad rows?
example file formet:
ORDERID~DATE~Comment~Address 1~2/3/2007~Some Comment~1234 oak st 2~2/3/2007~Some messed up comment~345 oak st. 3~2/3/2007~Another comment~3214 asdf blvd.
Is there a way (perhaps a property) to capture the number of rows selected from a Flat File Data Flow Source without having to develop a script to loop through the rows and count them?
In a dataflow there is a Flat File Source that loads a file with 500000 rows but when I execute the package it only loads 249999, I have verified the file and every looks fine, it is a csv and ms-excel recognized it perfectly.
I'm wondering if there is any technical limitation regarding to the amount of rows per file?
and what else can I verify for discover the problem?
I finally put together a SSIS package that takes a Text File and successfully imports its data into the right table. My question is, where in the package's properties can I find the option to Delete all rows from Destination Columns prior to Importing. I have looked everywhere in the Package Explorer for this setting. Thanx in advance.
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!
Sorry if this question had already been answered previously. I was unable search the forum on this topic. How will I merge these and then configure the first row as Column names (As this helps to map to the destination column names automatically)
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 |
Just attempting to import a simple tab delimited text file into my SQL Server 2005 database using the SQL Server Import and Export wizard. Column names are specified within the first line of the file. The Header Rows to Skip field value is listed as 0, but the wizard indicates that "The field, Header rows to skip, does not contain a valid numeric value".
Why isn't zero (0) a valid numeric value? I don't want to skip any rows. PLUS, I get the same error when trying to export to a text file although the header rows to skip field does not exist. I can increase the number to 1 or more, but the wizard will skip part of my data .. unacceptable.
What am I missing here? I installed SP1 of SQL server 2005, but that did not help.
All, I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!
I have a flat file.I am trying to set the value for the property "HeaderRowsToSkip" during runtime.I have set an expression for this in my "flat file connection manager". But this is not working.The connection manager is not able to take the value during runtime.
My expression is as follows:
DataRowsToSkip : @[user:: Var]
where "Var" is my variable which gets the value from the rowcount component and trying to set it back to the "HeaderRowsToskip" property.
I ve even tried setting the value to the "HeaderRowsToSkip" property in the expression builder.
i am dealing with around 14000 rows which need to be put into the sql destination.,But what i see is that the order of the rows in the desination is not the same as in the source,
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.
I have a situation where a tab limited text file is used to populate a sql server table.
The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS?
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?
I m using SSIS and i am transfering the data from Flat File Source to the OLE DB destination File. The source file contain some corrupt data which i am transfering to the other Flat file destination file.
Debugging is succesful but i am not getting any error output in the Flat file destination file.
i had done exactly which is written in the msdn tutorial of SSIS.
Plz tell me why i am not getting the error output in the destination flat file?
I have a set of flat files and transforming it to SQL server. If I do that in 2000 it was done with in 45 seconds for 1.5 M records. If I do the same in SSIS it takes 3 minutes. Why there is difference in time that too lower when compared to the previous version. I used the data access mode as "Fast load". Am I missing anything while doing through SSIS?
I need to randomly order the selected rows from my table. Is this better to do on the Application level or in a stored procedure using "orderby NewID()"?
Which is faster? There will be about 100 rows returned with 10 columns.
Is there any faster and efficient way for exporting or unloading the data from a table (Contains about 400 to 500 million rows) into a flat or raw file. I am using SQL server 2005 and the Export Utility in SQL Server is very slow.
