Import Large Field From SSIS
Apr 20, 2007
Hi,
I am making a SSIS package that imports data from a application using a custom ODBC driver. The field in the application is set to be a "longvarchar" type field and can be from 2 characters to 2MB of data.
I've created a ODBC data connection in the SSIS package and use a "DataReader Source" to read the data I need. The sql statement is very simple
Select log from tablename
When I try to run the SSIS package with that statement it just goes to yellow on the DataReader Source and stops. It stays like that until I stop it. If I select other fields except for that field it works fine. Also I've been able to get it to succeed getting the log field if I select a log record that's not too big. The largest one I've been able to get is 800 characters, but I got one with 2500 characters that just stops on yellow.
In the Progress log the last line says:
[DTS.Pipeline] Information: Execute phase is beginning.
Does anyone have any ideas on how to resolve this?

Importing data from an Access database, I cannot overcome the limit of 1,000 records.
In DTS, I "copy one or more tables", select tables, run, and cannot see my 1,052 entries.
Where can I set a max size of ~1,500 in my sql target base?

I was wondering if anyone can help me.
I am trying to import data into SQL Server 7. The table will be 700-800 columns, and the data will be about 150,000 records at a time.
The data source is flat file.
First I create the table using a database schema, and secondly I would like to populate the table.
The problem is that most of the data is numeric, and to be used for statistical analysis.
So far I have tried Bulk Insert, bcp, and dts.
DTS is the only method that has worked in any way, shape or form, but that requires importing each column as a Varchar. Importing to my pre-created table doesn't work, because it is interpreting some of the source columns as character data and refusing to insert them into an int field.
Bulk Insert and bcp both give error messages, and I am wondering if that is because of the size of the insert statement that is required to handle so many fields.
For the moment I am just trying to import the data in any way, but eventually, it will have to be run as an automated process, with the table structure probably needing to be altered as well.
Any help/suggestions would be very greatfully received.

Hello, All:
I have many, many Access databases that are roughly 1.5GB-3GBs each and they have millions of records. Each MS Access Database file corresponds to one Database in SQL server. I'm trying to simply transform the data as it is in Access to MS SQL 2005.
I'm using the 64 bit version of Windows Server 2003 and the 64 bit version of SQL 2005. The server is running four dual core AMD Operton processors and has 8GB of RAM with a 1TB RAID 5 configuration. I think the hardware should be sufficient but the SQL Server Import and Export Wizard can't seem to handle the large number of tables/records. If I do one table at a time, it works well; however, it produces the following error message whenever I try to import the entire database:
Pre-execute (Error)

Hi,
I am currently importing (and exporting) binary flat files to and from Db fields using the TEXTPTR and UPDATETEXT (or READTEXT for export) functions. This allows me to fetch/send the data in manageable packet sizes without the need to load complete files into RAM first.
Given that some files can be up to 1Gb in size I am keen to find out a new way of doing this since the announcement that TEXTPTR, READTEXT and UPDATETEXT are going to be removed from T-SQL.
I had a quick foray into SSIS but couldn't find anything suitable which brings me back to T-SQL. If anyone knows a nice elegant way of doing this and is prepared to share, that would be grand.
Thanks for your time,
Paul

I need to create script that will import large XML files (500 - 7GB) on a daily basis and store the data in a relational db structure.
What is the best and fastest way of importing such files. I have played around with smaller files and found the following.
1. SSIS XML Data Source: It doesn't seem to like the complex elements types and throws out the file.
2. Using Bulk File Import, sorting the file in XML variable and using XQuery to parse the file: This works but it can't take a file more than 2GB in size, so I can't use this method.
3. C# + XML Serialization: This also works, but seems to be terribly slow. I open the DB connection once, so it doesn't open and close for each db call, but still seems like it takes a long time.
how to import large XML quickly in a relational table structure?

I have set up transaction replication between two databases. Data from a table in the first database is replicated to the same table in another database.
The table at the publisher already has some data in it. The table at the subscriber is empty. When the replication is synchronizing, I get the following errors in the replication monitor:
*The process could not bulk copy into table "dbo"."virtualdatalocations_waitingqueues". (Source: MSSQL_REPL, Error number: MSSQL_REPL20037) Get help: http://help/MSSQL_REPL20037
*Field size too large
The table looks like this:
CREATE TABLE virtualdatalocations_waitingqueues (
dataid int ,
personid int ,
queueid int ,
CONSTRAINT FK_vw_dataid
FOREIGN KEY(dataid) REFERENCES datalocations(id) ON DELETE CASCADE ,
CONSTRAINT FK_vw_personid
FOREIGN KEY(personid) REFERENCES persons(id),
CONSTRAINT FK_vw_queueid
FOREIGN KEY(queueid)REFERENCES waitingqueues(id)
);
It used to run fine in the past. I couldn't find any help on google or on forums.
Any help or comments are greatly appreciated.

I have an tab delimiter ed file that I'm trying to load into a database using SSIS. The the database have a column called Comments that can hold up to 1000 Unicode characters (nvarchar[1000])
I have appropriately defined the flat file connection and marked every field to the intended length, but every time I run it it will give me the following error:
Data conversion failed. The data conversion for column "COMMENTS" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.
All the columns have a match, this specific column is has no field longer than 1000, larger record has 528 characters in it and the fields are defined as Unicode string in the file connection.
I already ran out of ideas of what may be giving this error, anyone has an idea of what else to try?

HiThis is a question of "what does it cost me".Lets say I have an integer value which would fit into a smallint fieldbut the field is actually defined as int or even larger as bigint.What would that "cost" me ? How would definitions larger than I need forthe values in the field affect me ?Its obvious that the volume of the database would grow but with the sizeof resources etc that we have nowadays disc space isn't a problem likeit used to be and i/o is much faster and many people would tell me "whocares" , or IS it a problem ?How does it affect performance of data retrieves ? Searches ? Updatesand inserts ? How would it affect all db access if tables are pointingat each other with foreign keys ?Thanks !David Greenberg

I've got two databases on the same server and replicate some tables from one database to another.The replication is configured so not to drop the table if it exists, but to delete the data based on the filter if one exists. There are two tables on the subscriber that have some extra columns.
I get "field size too large" error when trying to replicate them. Is there a workaround without having to make the publisher and the subscriber tables identical by schema?

Hi,
I have a problem where I want to import a 1.6 GB XML file with SSIS into a SQL Server database. My hunch is that SSIS is not very good with handling such large amount of XML data. My test shows that SSIS tries to read all of the file into memory.
Does anyone know if there is any solution of solving this memory problem. My problem is that I want to take this source XML file import it into a database, make some transformations on it (eliminate duplicates etc) then produce a NEW XML file as output in a different XSD-format.
Is really SSIS the right tool for this operation?
The source XML file also have mixed content on Complex Types which seems to be a problem for SSIS as well.
Best regs,

Hello,
I have a package that has over 80 sequence containers and as I added more sequence containers to the package I started encountered System.OutOfMemoryException error. I am planning to break up this package to six small packages. Is there a quick and safe way to do this? I have tried to use the copy and paste method by creating a new project and move a list of sequence containers over, that seemed to create even more work. Also, if the main package is splitting up to six smaller packages (the main package has the global variables that need to pass the values to the other child packages) how do the variables values pass onto the child packages?
Thank you so much in advance,
Andrew

Hi,
I am new here, and looking for some help with SQL import.
I am using SQL Server 2000.
Problem: I have a table called 'People', with a field that I wish to populate inside of it (Town).
I already have 500 records in the table.
I have a seperate csv file containing the primary key record (ID) information, and the information that I wish to put into the field (Town).
How can I import the information into the field 'Town' by inserting the correct information next to the ID in the CSV file (There are some that I do not have to import, so I cannot just insert straight in).

Hello,
I created a SSIS solution for reading data from dbase and storing them in SQL Server. In a ForEachDirectory-Loop up to one thousand dbase files are read and stored. The system where the packages are running has 16 GB RAM.
For the first few hundred dbase files everything goes fine, but then, the RAM seems not to suffice any more and a temp file is created (I changed the path in BufferTempStoragePath).
How can it be that there is a need to create temp files if there is so much RAM available?
Why is the RAM filled more and more during the SSIS package execution?
Is there anything I can do to release some of it? (it is running in a loop and there is no need to store all the data)
Could it be caused by dbase?? (I use Microsoft Jet 4.0 OLE DB Provider)
Another thing is that the temp file is not stored in the path I set in BufferTempStoragePath.
There are sufficient permissions set, but temp file is still created in user temp folder...
Any kind of help is very much appreciated!
Best Regards,
Stefan

I'm trying to import some Assessor data from a text file into a table and the field for Legal Description (column 2 in the source text file) in the table is of data type varchar(max) because some of the data goes over the 8K size. I get an error on the first row of importing that refers to column 2 (see 'Initial errors' below). I read the related post and changed the size of input column 2 to 8000 and got this error. Finally I set the size of the of input column 2 to 4000 and it ran. So I'm thinking there is a limit on the size of varchar data that can be imported. Just want to clarify what that limit is and how I might go about importing this data.
Thanks, John

Hi,
I am having issues importing data from a text file into a SQL database table using the import wizard in SQL Server 2005.
The text file contains polygon coordinates and a polygon name and looks like this:
"42.2342342,-121.1351398|42.3467984752,-122.2349234, ... ..., 42.1897498174,-122.131983","Polygon Name 1"
"42.2342342,-121.1351398|42.3467984752,-122.2349234, ... ..., 42.1897498174,-122.131983","Polygon Name 2"
and the SQL table looks like this:
polycoordinates varbinary(MAX)
polygonname varchar(50)
The length of the longest polygon coordinates record is about 115,000 characters. I believe the varbinary(MAX) type should hold that data, but SQL throws a truncation error every time I try to import the data.
Any suggestions?
Thanks,
Jay

I am importing a file creating by an application which exports the file into .dbf format. Very unfortunately, this .dbf file can have fields with IDENTICAL column_names. Utilizing ActiveX, I create an ado connection to the .dbf file using a visual foxpro drver. However, and not unexpectantly, I can not do the 'select *' from the file if there are duplicate names.
Can anyone make recommendations here that might help?

First off, it has been a few years since I have done extensive work with SQL and that was using Oracle. But I am trying to develop a simple asset database for work, as we have nothing in place. I started out with Access, and decided to move to SQL express for many reasons.
What I have now is that I imported my data from my access 97 database to Excel, only my AssetTable did not import dates, I assume because Access and Sql Express handle dates differently... so a the time I just ignored that column.
Is it possible to insert the dates into the now populated SQL Express database AssetTbl where the AssetID's match? Here is what I have.
Sql Express Database Name: BAMS
Table Name: AssetTbl
fields: AssetID, SerialNum ...(many other fields)... DateAcq <- currently Null
Excel file: AssetDateAcq.xls
fields: AssetID, DateAcq (in format 07/12/2007)
To me it sounds like I need to do a short script/program to loop through the file read an AssetID from the excel file, and the DateAqcuired and then have it do an update on the DateAcq field, but it has been so long since I've done any work with SQL that I am finding there is a lot of "Dust" to blow off, and I don't know if I'm heading down the right track... or completely off course.
Thank you.

I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

It appears that when you use the import/export wizard from within Microsoft SQL Server Managment Studio, the identity attributes of the table being copied are not transferred. For example, say the source table has a column
[ref] [int] IDENTITY ( 1 , 1 ) NOT NULL,
When the import wizard is done the destination table will have a column named ref, but will not be an identity column. The column definition will be
[ref] [int] NOT NULL,
instead. Is there a way to change this behavior somewhere in the gui? When doing the import, the only options seems to be 'Enable Identity Insert', but checking this does not affect the definition of the column.

I have used DTS in SQL Server 2000 to import an MDB filed (MS ACCESS) of a table. When the table is imported the primary key is lost and the memo field data is completely gone.
I use the tranformation option in the DTS wizard to add the primary key and make sure the data type for the memo field is varchar and has a size of 8000. I need that large size since I am storing lots of html code.
When I preview the data I see the html code that is supposed to get imported. However, when I return all rows from the table in Enterprise Manager the field is empty.
So I tried to manually copy the data from the MS Access Database into SQL Server. Could not figure out if SQL Server has an interface like MS Access to simply copy data into a table. So I linked to the tables from MS Access to the SQL Server table.
When I opened the linked table I see the data in the description field. However, if I return the rows from within SQL Server no data is present.
I have some ASP code trying to read the data in the SQL Server table. However, nothing is returned and when I run the SQL Statement, nothing gets returned. The SQL statement returns all rows. All the other data is present but nothing in the description field.
What am I doing wrong? Any suggestions anyone, please!
TIA

We have a flat file import proces which imports data from a series of unicode flat files.
The files have text qualifiers and are being imported to a table with the following format:
CREATE TABLE [dsa].[OBS](
[Kundenummer] [nvarchar](10) NULL,
[Navn] [nvarchar](60) NULL,
[Adresse] [nvarchar](50) NULL,
[PostnrBynavn] [nvarchar](50) NULL,
[Kursusdato] [datetime] NULL,
[Varighed] [decimal](18, 2) NULL,
[Kursustype] [nvarchar](100) NULL,
[Risikokoder] [nvarchar](50) NULL
) ON [PRIMARY]
In one of our files we have two rows that looks like this:
"19298529";"THIS IS ROW 1";"ADDRESS 9 -13";"4200 SLAGELSE";"02-05-2006";8.00;"Kombikursus Førstehjælp - Brand 8 lek.";"37"
"19448242";"THIS IS ROW 2";"ADDRESS 50";"4140 BORUP";"04-05-2006";4.00;""Fra vil selv - til kan selv". Om børn 1½ - 3 Ã¥r";"22"
Both rows are OK according to the format, but the second row actually contains the text qualifier in one of the qualified fields (""Fra vil selv - til kan selv". Om børn 1½ - 3 Ã¥r"). It's the title of a course with a comment.
The proces fails on this file, and wont even redirect the row, as it does on other erroneous rows in other files we import.
We believe this is a valid text, but apparently SSIS doesn't
Is this a bug or is this record not allowed?
Is there a work around, and why wont SSIS redirect the row?
We believe the reason is that the field before is not text quaified (which is of course specified in the connection manager).
Thanks in advance,
Lasse

In MS Excel, the ability exists to run a "web query." This functionis accessed via the data menu's import external data option. The webquery wizard accepts a URL address, and then is able to import thedata from that address into an excel worksheet.What I would like to do is use SSIS to import data from the same website. In other words, I now use Excel's web query functionality toimport data from a website with a url of xyz.asp. I save the excelworkbook, and then run a DTS package to import the data into SQLServer. I would like to entirely bypass Excel, instead of using it asan intermediary to bring data from the asp site into SQL Server.However, I can't figure out how to set up the connection from SQLServer. I am using SQL Server 2005, SSIS. Is there a way to haveSSIS open the asp website, extract the data and import it into a SQLServer table?For the record, this is not XML data.Thanks.

Hi,
I have stumbled on a problem with running a large number of SSIS packages in parallel, using the €œdtexec€? command from inside an SQL Server job.
I€™ve described the environment, the goal and the problem below. Sorry if it€™s a bit too long, but I tried to be as clear as possible.
The environment:
Windows Server 2003 Enterprise x64 Edition, SQL Server 2005 32bit Enterprise Edition SP2.
The goal:
We have a large number of text files that we€™re loading into a staging area of a data warehouse (based on SQL Server 2k5, as said above).
We have one €œmain€? SSIS package that takes a list of files to load from an XML file, loops through that list and for each file in the list starts an SSIS package by using €œdtexec€? command. The command is started asynchronously by using system.diagnostics.process.start() method. This means that a large number of SSIS packages are started in parallel. These packages perform the actual loading (with BULK insert).
I have successfully run the loading process from the command prompt (using the dtexec command to start the main package) a number of times.
In order to move the loading to a production environment and schedule it, we have set up an SQL Server Agent job. We€™ve created a proxy user with the necessary rights (the same user that runs the job from command prompt), created an the SQL Agent job (there is one step of type €œcmdexec€? that runs the €œmain€? SSIS package with the €œdtexec€? command).
If the input XML file for the main package contains a small number of files (for example 10), the SQL Server Agent job works fine €“ the SSIS packages are started in parallel and they finish work successfully.
The problem:
When the number of the concurrently started SSIS packages gets too big, the packages start to fail. When a large number of SSIS package executions are already taking place, the new dtexec commands fail after 0 seconds of work with an empty error message.
Please bear in mind that the same loading still works perfectly from command prompt on the same server with the same user. It only fails when run from the SQL Agent Job.
I€™ve tried to understand the limit, when do the packages start to fail, and I believe that the threshold is 80 parallel executions (I understand that it might not be desirable to start so many SSIS packages at once, but I€™d like to do it despite this).
Additional information:
The dtexec utility provides an error message where the package variables are shown and the fact that the package ran 0 seconds, but the €œMessage€? is empty (€œMessage: €œ).
Turning the logging on in all the packages does not provide an error message either, just a lot of run-time information.
The try-catch block around the process.start() script in the main package€™s script task also does not reveal any errors.
I€™ve increased the €œmax worker threads€? number for the cmdexec subsystem in the msdb.dbo.syssubsystems table to a safely high number and restarted the SQL Server, but this had no effect either.
The request:
Can anyone give ideas what could be the cause of the problem?
If you have any ideas about how to further debug the problem, they are also very welcome.
Thanks in advance!
