Exported Flat File Data Will Not Import To Same Table Without Extensive Data-type Manipulation
Jul 13, 2007
I'm moving data between identical tables and have to use a flat file as an intermediary. I thought: "No problem, SSIS can do a quick export to a file, then move the file to another server, then use SSIS to import the data to the new server."
Seems simple, right?
I'm hitting all sorts of surprising data conversion errors. I used the export wizard to create the export package. This works fine. However using the same flat file definition, the import package fails -- even when I have no destination. That is I have just one data flow task that contains only one control: the Flat File source. When I run the package the flat file definition fails with data type conversion and truncation errors. One of the obvious errors is for boolean types. The SQL field is a bit, SSIS defined the column as DT_BOOL, the output of the data are literal text values "TRUE" and "FALSE". So SSIS converts a sql datatype of bit to "TRUE" and "FALSE" on export, but can't make the reverse conversion on import?
Does anyone else find this surprising? I would expect that what SSIS exports, it can import given all the same table and flat file definitions. Is SSIS the wrong tool to do such simple bulk copies? I'd like to avoid using BCP because this process will need to run automatically within SQL Agent so we can leverage all the error tracking and system monitoring.

I have one column in SQL Server 2005 of data type VARCHAR(4000).
I have imported sql Server 2005 database data into one mdb file.After importing a data into the mdb file, above column
data type converted into the memo type in the Access database.
now when I am trying to import a data from this MS Access File(db1.mdb) into the another SQL Server 2005 database, got the error of Unicode Converting a memo data type conversion in Export/Import data wizard.
Could you please let me know what is the reason?
I know that memo data type does not supported into the SQl Server 2005.
I am with SQL Server 2005 Standard Edition with SP2.
Please help me to understans this issue correctly?

Hi,
I wanted to know if there was a way to import data from a flat file without specifiying the delimiters. I want to import each line in one row so that i can use the substring function to break of the data as an when i want and not as per the delimited format file or the wizard.
i.e if row one had "abc"|"1453"|"Jack"|"Smith"| etc.... rather than importing these as different columns and rows. I want this all in one row, one column.
Is it Possible?

Hello all,
We have been trying now for the past 2 days to import data from a flat file to sql server database but with no luck.
The real issue here is that one of the field names has a very long value.
As a result, the import fails because it is unable to truncate the value.
We really don't want the value truncated but we have not been able to import the entire data file.
We have used nvarchar(max) but it doesn't work.
Can someone please let me know if you have encountered this type of issue and how was it resolved?
Thanks in advance.

It seems I can do the type conversion in two place:
1. The advanced editor for flat file source => Input and output roperties. And I can set the output columns data type properties there.
2. Using a Data conversion box in Data flow transformation.
Any difference between these two? Which one should be used?

Hi,
Iam trying to import data from a csv file into my table in SQL Server 2000. My table is called as temp_table and consists of 3 fields.
column datatype
-------- -----------
program nvarchar(20)
description nvarchar(50)
pId int
pId has been set to primary key with auto_increment.
My csv file has 2 columns of data and it looks like follows:
program, description
"prog1", "this is program1"
"prog2", "this is program2"
"prog3", "this is program3"
Now i use BULK INSERT like this
"BULK INSERT ord_programs FROM 'C:datafile.csv' WITH (FIELDTERMINATOR=',', ROWTERMINATOR='', FIRSTROW=2)"
to import data into my table in SQL server and it gives me this error
"Bulk insert data conversion error (type mismatch) for row 2, column 3 (pId)"
I guess i have to use fileformat or something since i dont have anything for pId field in the csv file to make it work...
Please help me out guys and please post a snippet of code if you have.
Thank You.

I built a DTS Import Package to import an HTM file and it went smooth as silk. Replaced the file with another HTM Table of the same name and whammo a text field turned into an integer file and data goes missing. The first 20 or so rows of a particular column were all numbers. I tried to do a disconnected edit to alter the Source column to a string but the Edit button just disappears without changing the column's type value. The only way I can think of getting around this is to use something archiac like EDLIN to add a new table row at the top of the HTM Table with values to force the specified type. Anyone think of a better solution?

I need to do some advanced formatting in the text file, because the data in the text file is bit complex. I have some knowledge of using BCP, BULK INSERT and bit about FORMAT FILES but I want to do some advanced formatting(using IF condition and all) to pull the data from text file.
Can anyone please tell me how can I perform bit advanced formatting using BULK INSERT?
Cheers

If the system not able to convert the data from one data type(string,int) to another data type then i need to move the reocord into my error_table.
How to redirect the bad data into another table, while extracting the flat file data ?
Bad Data means if the system not able to convert the data from one data type to another data type.
Say €œX2R322€? data can€™t convert as DATE data type but "070899" can be converted as DATE data type.
Thank you very much.

I am running a set of SQL statements on a SQL server, to insert flat file data into a SQL table. The flat file is already FTP'ed to the SQL server. I seem to be getting an error, which is possibly pointing to a permissions issue
The statements:
BULK INSERT [Jedox_prod].[dbo].[B_BP_Customer]
FROM 'c:jedox_dailyjdcom4401.txt'
WITH
(
FIRSTROW = 2,
MAXERRORS = 0,
FIELDTERMINATOR = '|',
ROWTERMINATOR = '
'
)
GO
The error is :
Msg 4861, Level 16, State 1, Line 1
Cannot bulk load because the file "c:jedox_dailyjdcom4401.txt" could not be opened. Operating system error code 3(failed to retrieve text for this error. Reason: 1815)
If it is permissions issue, how do I overcome this?

This question is around how we can get the data types and lengths populated into the flat file source columns.
In Connection Manager, you have your flat file defined. You can choose "Suggest Types...", and the minimum lengths and correct data types will be returned from within the data in the flat file.
Is there some way to automate this data type definition, but coming from the other direction (coming from the destination table that we are loading)?
For example, you have mapped the columns that will be loaded. Can you then reverse engineer the data types and lengths for the columns in the flat file from the destination table?
TIA

I have a table dbo.Sales that contains all sales records. There is a column in that table called ItemNumber that I'd like to match with ItemNumber in a flat file and update the ItemCost based on the ItemCost column in the flat file.
So while there will be many sales records for each ItemNumber, I need to loop through and update the ItemCost in that sales record based on the corresponding ItemCost in the flat file. Does this make sense? I really need this for court and I can't figure out how to do it. I took a SQL course about 7 years ago but have forgotten everything.
Database Name: BTData
Database Table: dbo.Sales
Database Columns: ItemNumber (match on this), ItemCost (update this)
FlatFile Name: InventoryCosts.txt
FlatFile Columns: ItemNumber, ItemCost
There will be many sales records for each ItemNumber in the database table. I need to update each one with correct cost based on the item number and cost mapping from flat file.

Hi all,
I am facing a problem on validating the data from a flat file while inserting the data into the destination table of sql server 2005 database. In my package, i have to validate the input data whether the values are coming as null or not, before inserting into the destination database. The flat file may not contain data for all NOT NULL columns. I have to find out that row(s) and reject the record. If the rows are coming as Null for the Not Null columns, the OLEDB Destination throws OLEDB exception for the constraint.
To resolve this, i have an script component in data flow, to check whether the input data is coming as null. I have added the output column of boolean type to the script component, it will be assigned to TRUE when there is null for the Not Null column in the script.
And in the follwing conditional split, i am checking the flag for TRUE to reject the record.
Is there any other way to handle this validation?
Regards
Madhav

Hello,
I am new to this sql server reporting server technology. I have a requirement like the table header should repeat in all pages of the exported excel's print preview. So I have created the header columns with fixed lenths as same as table's header in the page header of the report. Then only the Header will repeat in all pages of the print preview.
But the problem is when doing like this, many of the columns have been merged together. The report layout is ok. But cant sort the data. It says a message "This operation requires the merged cells to be identically sized."
In some forms i have found the header control's edges need to be sized identically with the tables' columns edges. I did it. But still the columns are merged when exporting.
Please help me out from this.
Thanks in advance.

Hi
I'm used to DTS but new to SSIS. What's a good reference/tutorial that deals with transforming columns of data (from a flat file) from one format to another when uploading into SQL2005? Typically columns of data have "" around the values and spaces that I want to remove.
Presumably in SSIS I need the following:
A Data flow task containing:
Flat file source
Derived or Copy Column?
OLE DB Destination
Is this on the right track?
Thanks

Hi,
I'm new to SQL Server 2005 SSIS. I'm trying to do something very simple, but I cannot figure it out, PLEASE HELP!
I have a flat file, which I read and then insert the data in a database table, that works fine. The problem is that I don't want to insert duplicate records. For example; if I run the package again, it will appent to the table. What I need to do is that if the package runs again, check if the record already exist, based one two columns, date and hour, and do not insert the record.
Thank you,

The following error is encountered when importing a delimited flat file with date of fomat "dd.mm.yyyy"
Error: 0xC02020A1 at Data Flow Task, Source - DCDtest_xpt [1]: Data conversion failed. The data conversion for column "value date" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
This was when I manually built the package.
I get the same error when using the Import/Export wizard
I am even using the "suggest types" button and have tried sampling the default number of rows (?200) and also 2000.
The type it suggests is DT_DATE.
But reading the BOL, this would appear to be the wrong type:
http://msdn2.microsoft.com/en-us/library/ms141036.aspx (obviously the right hand doesn't know what the left hand is doing)
seems to indicate that
DT_DBTIMESTAMP
is the correct value
(I cannot believe that they have different datatypes in SSIS than in SQL. I can't believe for a minute this is for all the hundreds of thousands of Oracle users who obviously switched to SSIS when they saw what a high quality product it is.)
I tried other DT_... values but no dice.
Can anyone help?
I always thought that Classic ASP was the worst product I've ever worked with from the Microsoft stable, but I was wrong.
I am fed up of having to post on this board (no wonder it is so 'popular')
Talking to peers, reading books, googling nearly always enables me to figure out a problem with any application I have ever used, but SSIS breaks the mould in sheer crapness and the weirdnes and unfathomability of its cryptic errors,.
Rant over (for today)

In my SSIS package I have flat files as a source, I have to load numbers of flat files into SQL target table. I am using For each loop container for that. I am doing it correctly. My aim is to validate the source data from all angle before writing it into target sql table. I am using below points to validate the source data , if I found any bad data I am redirecting those data to error output.
To Checking
1. To check whether data type of column.
2. To check whether buisinesskey column null.
Is there any thing which I am missing to validate source data.

I am having one store procedure which use to load data from flat file to staging table dynamically.
Everything is working fine.staging_temp table have single column. All the data stored in that single column. below is the sample row.
AB¯ALBERTA ¯93¯AI
AI¯ALBERTA INDIRECT ¯94¯AI
AL¯ALABAMA ¯30¯
After the staging_temp data gets inserted into main table.my probelm is to handle such a file where number of columns are more than the actual table.
If you see the sample rows there are 4 column separated by "¯".but actual I am having only 3 columns in my main table.so how can I get only first 3 column from the satging_temp table.
Output should be like below.
AB¯ALBERTA ¯93
AI¯ALBERTA INDIRECT ¯94

I have requirement like to develop dynamic package for inserting data from flat file to table.
Find below points for more clarification :--
1) if I changed the flat file values and name in source variable AND  the table name should be also changed based on variable value .
2) it should dynamically mapped with column values with source file as we have to insert data in target table.
See below diagram for more clarification.

How do i import a Varying Column Width Flat file into a Table using SSIS?
I have a flat file that has 4 columns with varying width
Like I should read the file as
Col 1 - (1 to 10 Characters)
Col 2 - (12 to 21 Characters)
Col 3 - (22 to 35 Characters)
Col 4 - (36 to 38 Characters)
At the end of the record is a "LF"
I think "Fixed Width" Columns allow me to define a standard column length for all the columns.. Right?
Any thoughts on how to?

I'm new to SSIS and have run into a problem I'm hoping someone can help me with.
Basically, I have a flat file that looks something like:
ID,Type,Description,Results
1,Test1,This is a test,5
2,Test1,This is also a 1 test,7
3,Test1,This is also a 1 test,13
4,Test2,This is a second test,14
5,Test2,This is also a second test,18
I'm trying to normalize the data by extracting out individual rows that have the same "Type" column value. So what I want is to extract each unique type and description into a separate table. This would give me two new rows, one for a type of Test1, and one for a type of Test2, with the descriptions. Does this make sense? Then I could relate the individual results to these test types. In my scenario, I don't care which description is used; I just want to take the first description that shows up with the associated "Type."
Does anyone have any idea of how I could go about doing this? I could pull out all unique "Types" from the rows with the Aggregate transformation, but I'm trying to figure out how to get the description that goes along with it.
Thanks,
Brian
