Export Multiple Tables To Multiple Flat Files
Nov 29, 2007
I used the data export wizard to export a single table to a single flat file (multiple wasn't allowed). I saved the package as a *.dtsx file which I'm attempting to edit to add the additional tables.
Creating additional sources is fairly easy copy of the first source and change to the table name.
I've tried copying the destination connection and changing to a new text file, but can't get past having to add each column manually to the new destination.
How can I duplicate the mapping that must be taking place in the wizard in the *.dtsx editing environment?
This seems like a simple / common task, but I've been unable to find a solution.
Thanks, Richard

I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?

Hi,
I have searched but not found quite the best way to look at this so far..
I have an application that outputs data to several text files (up to 30). These have commonality by an object name, but then contain completely different column data.
In DTS I had each of the source text file connections going to one OLE DB connection and then individual transform data tasks pointing to the one OLE DB connection.
Looking at SSIS, it would appear that I would need to have one source and one destination for each of these and therefore 30 parallel data flows?
Just wondering if there is a neater way of doing this??
It is a regular data import that happens a few times a day - the text files are named the same as the SQL tables - ie app_userdata.txt goes to app_userdata table.
Hope that explains ok and thanks in advance.
Mike

So we are running SQL 2000 and we use a DTS Package to load about 100 txt files to different tables in a SQL DB.
So in DTS packages you define the connection (database) and the different source files will connect to the connection.
You define the destination on the flow arrow. My question is how do i accomplish this in SQL 2008 using SSIS. (upgrading SQL).

Hi.
I've tried to create a SSIS package to simply export a bunch of tables as flat files, and am having troubles because when the for each loop hits the second table the column mappings in the flat file destination are not synchronised with its schema.
I created a for each loop with an enumerator that returns the table names and sets a user variable.
I created a data flow task which dynamically connects to the table name variable.
In the Flat File Destination there is a column mapping property, but I don't know how to reset these mappings on each iteration.
Any ideas?

I 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?

I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.

I need to be able to bulk insert a bunch of tables from their corresponding flat file. I have created an XML file (see below) which has the file name/table name pair at each node. I then created a ForEachLoop task and used the Node enumeration type and the following OuterXpathString: ReferenceFiles/File. At this point I get lost. How do I pass the 2 inside node values (file name and table name) to variables which I can then use as expressions for the bulk insert task inside the Foreach?
Here is XML file:
Code Snippet
<ReferenceFiles>
<File>
<FileName>Ref_Categories.txt</FileName>
<TableName>Ref_Categories</TableName>
</File>
<File>
<FileName>Ref_Configs.txt</FileName>
<TableName>Ref_Configs</TableName>
</File>
</ReferenceFiles>
Thanks.

I am trying to write (my first, unfortunatly) DTS, and am having some problems.
I need to be able to import multiple flatfiles (all in the same format, just with different schema), each one going into a different table. I have written an application to call my DTS, sending it variables for the tablename and the filename. This works fine when I test it on a single flatfile.
My problem is, the Tranformation object does not reset after each DTS call, so I get "Column does not exist" errors after the first successful import. I can go into the DTS Manager and reset the Transformation options, but that would defeat the purpose of automation. Is there anyway to reset, or another technique, the Transformation object so that it will continuosly work on files that use different schema?
I am very new at DTS, so please consider me "ignorant" when replying.
Thanks in advance.

Hi,
I'm just learning SSIS. As I was following the tutorial on foreach loop container (lesson 2) to export multiple flat files in creating a simple ETL package in SSIS, I get the following error:
SSIS package "Take17.dtsx" starting.

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "Take17.dtsx" finished: Failure.
I spent some time in understanding where could be the error. I traced it to the following place. If you take a look at the Lesson#2 in creating a simple ETL package in SSIS, using foreach loop container to import files into SQL server, as soon as I finish going through steps in configuring the file connection manager to use the variable for connectionstring, it immediately disappears. I repeated the tutorial three times exactly as I pointed out and when I reach to this step of configuring file connection manager for connectionstring, it takes the path and when I start debugging it, I get this error. When I go and check if everything is Ok, the connectionstring value is empty.
Why the value in connectionstring disappears?
Thank you.

So here's the issue
16 flat files all fixed width. Some over 350 columns.
Open flat file 1
extract id and go see if its in table 1, if true update table 1 with first 30 columns
otherwise insert into table 1 first 30 columns.
goto table 2, lookup id, insert/update next 30 columns...etc..etc..for 10 different tables
So I've got my flat file source, I do a derived column to convert the dates, i've got a lookup for table 1, then 2 ole db commands, 1 for update if lookup successful, 1 for insert if lookup fails.
How can I pass the id as a param into the update command so it updates where x = 'x'
also I need a pointer on doing the next lookup, eg table 2, would I do this as some sort of loop?.
If you can help great, but, please don't just reply with "I'd use this object"...then no explanation of how

Probably a stupid and regularly asked question but I can't seem to find an answer, so here goes,
we have 16 .txt files, some with over 350 columns.
That info from each individual file needs importing to multiple sql tables.
need to look at sql table1 does record exist? if not create new then add in data once its been transformed eg datetime from yyyymmdd into datetime values [managed to get this using derived column] for first 20 columns, otherwise do update for the 20 columns...
then look at sql table2 and repeat for next n columns....
So I was wondering is it going to be better to write this as a dtsx package? if so can you point me to an example
or should I just write the code as part of a code behind page that scrapes the info and does a standard update/insert procedure?
Any help would be welcome.
thanks

Hi all,
I work on a data warehouse. My source system is moving from Oracle to Sql Server. I'm looking for a way to export multiple tables into distinct files. I've started using DTS 'Export Data' function, but that is one table at a time. I'd like to put multiple input/outputs into a package so that I can run one package to take care of a bunch of small tables while I run my larger tables simulataneously. Right now, it seems that I'll need to make one DTS package per table. Any suggestions how I might be able to avoid that? Thanks.

Hi ,
I need to export data from sql data base tables to .csv files with vertical bar (column seperator).The names of the .csv file is to be similar to table name. Eg. exporting Employee table should result in Employee.txt / Employee.csv
Using export / import wizard I could export only 1 table at a time to text file.
The content in the file will be as shown below:
EMP |ALL |103000353|102000001|104000000|n
EQUP|ALL |104000117|104000001|105000000|n
As there are huge number of tables and I need to transfer all the user tables to text files seperately, Is there any method / sql query / script to export multiple tables at a time , such that with a single execution i could export 100 tables to 100 text files individually.
Looking forward for solution

We are trying to use SSIS Import export wizrd to import the flat files (CSV format) that we have into MS SQL Server 2005 database tables. We have huge number of CSV files. Is there a way by which we can import these flat (CSV) files in to corresponding SQL server tables in a single shot. I would really appreciate this help as it is painful to convert each and every file using the Import Export wizard.
Thank you very much,

Hi,
I want to combine a series of outputs from tsql queries into a single flat file destination using SSIS.
Does anyone have any inkling into how I would do this.
I know that I can configure a flat file connection manager to accept the output from the first oledb source, but am having difficulty with subsequent queries.
e.g. output
personID, personForename, personSurname,
1, pf, langan
***Roles
roleID, roleName
1, developer
2, architect
3, business analyst
4, project manager
5, general manager
6, ceo
***joinPersonRoles
personID,roleID
1,1
1,2
1,3
1,4
1,5
1,6

I have a report with 2 tablixes, both the tablixes can be hidden based on the parameter selection. The 1st tablix has a drill through action on one of the columns, that calls the 2nd tablix in the SAME report. Once you click on the drill through, the 1st tablix is no longer visible, only the 2nd one is.
The report is working fine, until you export it to CSV file. Once you are on the 2nd tablix (1st one is NOT visible at this time in the report), and then when you export it to CSV, BOTH, the 1st tablix as well as 2nd tablix are visible in the CSV file. Why does the 1st tablix come up in CSV IF you just exported 2nd tablix to CSV?
Is there a workaround to NOT show the parent/1st tablix at all if the 2nd tablix is exported? Excel works fine!I know sub-reports instead of multiple tablixes might solve this issue.

Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob

I am trying to restore multiple .bak backup SQL database files onto a new server. However, I have found that it will not allow me to restore multiple databases at once. Is there a way to do this so that I do not have to manually upload one at a time? I tried adding all the .bak files at once to the backup device window but it only did the first one listed. It would be so much easier to restore them all at once so that I do not have to continue this manual process. I am restoring them via device.

I have just taken over the job of sorting out a rather poorly designed database. It looks like it was 'upsized' from an access database to the SQL server. The SQL server is the 2000 version.
Now I am trying to generate a report of what the students in the database are owing by referencing the Receipt table and then all the available payment methods and allocations. I was wondering if there was anyway to work out data being displayed twice (Let me demonstrate)
Note1: All the tables are linked by a key of ReceiptNo. From what I can see there is a table for every payment type and allocation but no link between the two other then the receipt number.
Using the query:
SELECT T_Receipt.ReceiptNo, T_cheque.Amount AS Chq_Amount, T_credit.Amount AS Cre_Amount, StandingOrder.Amount AS Stn_Amount,
T_BankTransfer.amount AS Bnk_Amount, T_cash.TotalAmount AS Cas_Amount, T_RentPayment.AmountPayed AS Ren_Paid,
T_AdminPayment.AmountPaid AS Adm_Paid, T_InternetBilling.Total AS Int_Paid, T_Utilities.AmountPaid AS Util_Amount,
T_InvoicePayment.amountPaid AS Inv_Paid, T_OtherPayments.paymentAmount AS Oth_Paid, T_parkingBill.paymentAmount AS Prk_Paid,
T_TelephoneBills.TelephoneCredit AS Tel_Paid, T_DepositPayment.[Deposit payment] AS Dep_Amount, T_Receipt.cancelled AS Canceled,
T_Receipt.RemittanceReceiptNo AS Rec_Ref, T_Receipt.Student
FROM T_Receipt INNER JOIN
T_DepositPayment ON T_Receipt.ReceiptNo = T_DepositPayment.receiptNo LEFT OUTER JOIN
T_RentPayment ON T_Receipt.ReceiptNo = T_RentPayment.RentPaymentNo LEFT OUTER JOIN
StandingOrder ON T_Receipt.ReceiptNo = StandingOrder.ReceiptNo LEFT OUTER JOIN
T_TelephoneBills ON T_Receipt.ReceiptNo = T_TelephoneBills.ReceiptNo LEFT OUTER JOIN
T_parkingBill ON T_Receipt.ReceiptNo = T_parkingBill.ReceiptNo LEFT OUTER JOIN
T_OtherPayments ON T_Receipt.ReceiptNo = T_OtherPayments.ReceiptNo LEFT OUTER JOIN
T_InvoicePayment ON T_Receipt.ReceiptNo = T_InvoicePayment.receiptNo LEFT OUTER JOIN
T_cash ON T_Receipt.ReceiptNo = T_cash.ReceiptNo LEFT OUTER JOIN
T_AdminPayment ON T_Receipt.ReceiptNo = T_AdminPayment.ReceiptNo LEFT OUTER JOIN
T_BankTransfer ON T_Receipt.ReceiptNo = T_BankTransfer.receiptNo LEFT OUTER JOIN
T_Utilities ON T_Receipt.ReceiptNo = T_Utilities.receiptNo LEFT OUTER JOIN
T_credit ON T_Receipt.ReceiptNo = T_credit.ReceiptNo LEFT OUTER JOIN
T_cheque ON T_Receipt.ReceiptNo = T_cheque.ReceiptNo LEFT OUTER JOIN
T_InternetBilling ON T_Receipt.ReceiptNo = T_InternetBilling.ReceiptNo
GROUP BY T_Receipt.Student, T_Receipt.ReceiptNo, T_cheque.Amount, T_credit.Amount, StandingOrder.Amount, T_BankTransfer.amount, T_cash.TotalAmount,
T_AdminPayment.AmountPaid, T_InternetBilling.Total, T_Utilities.AmountPaid, T_InvoicePayment.amountPaid, T_OtherPayments.paymentAmount,
T_parkingBill.paymentAmount, T_TelephoneBills.TelephoneCredit, T_Receipt.cancelled, T_Receipt.RemittanceReceiptNo,
T_DepositPayment.[Deposit payment], T_RentPayment.AmountPayed, T_Receipt.Student
HAVING (T_Receipt.Student LIKE N'06%')
Which gives a result of:
RecNo.
30429
Cheque
250
Deposit
250
30429
679.98
250
This is fine but when I do analysis on this it appears as though the student has paid two deposit payments. I was wondering with out querying each table independently from an application if there was a criteria to specify that I only get one deposit result.
So as such say, give me all the payments but I only want one result from the other tables. I though about discrete but that wouldn't work here.

Hi!
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)
Any pointer most welcome!
best regards and thanks

Hello,
I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services?
Thanks
