SQL Bulk Insert Challenge
Nov 27, 2007
I have a text file that is exported from an application and comes in a specific format. I would like to use BULK INSERT in order to load it into my own SQL 2005 database. The trick is that the file contains several different record lengths/layouts. These record layouts are identified by a specific string in column1 of each row in the text file. I would like if possible to bulk insert each specific record/row type into a seperate table.
For example, if the first column in a row contains the string "X1" I know this row contain will contain 7 tab delimited columns. As such, I would like to be able to import only rows which contain an "X1" in the first column into a specific table. If the first column in the row contains the string "X2" I know this row will contain 10 tab delimited columns. As such, I would like to be able to import only rows which contain an "X2" in the first column into a specific table. And so on and so forth. Its basically a header/detail file in a single text file.
I have not been able to find any combination of using format files with BULK INSERT or any other settings/techniques that will alow me to use BULK INSERT to achieve this.
Previously, I was using ADO from within Access to import these files by making several copies of the file first and giving them specific filenames representing each different record layout. I then had each different filename defined defined in a schema.ini file which each specific record layout. I then used a simple SQL query to retrieve for example only rows where [Column1] = "X1" when reading the X1_Filename.
Any thoughts? And please, try to keep it reasonably simple as I am not exactly an advanced user.

Hello,
I'm just learning SSIS and I've hit my first bump. I am doing a bulk import from a tab delimited text file to an empty sql table that has a Idendity column defined. How do I tell the bulk insert task to skip that column when inserting from the text file. If I remove the identity column it imports the data fine, but I want to create the indentity column in the table too.
Thanks.

Im having some issues with bulk insert.
This is the table:
CREATE TABLE [dbo].[tmp_GA_status](
[GA_recno] [int] NOT NULL,
[GA_desc] [varchar](40) NULL
)
This is the file (unicode):
1|"test1"
2|"test2"
3|"test3"
4|"test4"
5|"test5"
6|"test6"
7|"test7"
8|"test8"
and this is the sql:
bulk insert tmp_GA_status from 'C: empTextDumpGA_status.dta'
with (CODEPAGE='RAW', FIELDTERMINATOR='|', ROWTERMINATOR='
', DATAFILETYPE='widechar')
so yeah, pretty simple. But whatever I do I get this;
Msg 4864, Level 16, State 1, Line 1
Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 2 (GA_desc).
So what am I doing wrong ?

I have to update a field within a table of 60 records or so. Each record has a different field value. it's type varchar. i was given an excel file with the field values and was thinking of a bulk update like bulk insert, but i don't recall that it's possible that way.
Is the only way to create a table, bulk insert, then merge the two tables together with UPDATE?
Just wanted to see if there was an easier way to do it, otherwise i'll take the latter route. Thanks!

I have a table containing 8 million records.
I need to replace 2 million of these records with
a scaled down query that goes something like:
SELECT 1, ShareholderID, Assets1
FROM MyTable (Yields appx. 200,000 recods)
SELECT 2, ShareholderID, Assets2
FROM MyTable (Yields appx. 200,000 recods)
.
.
.
SELECT 10, ShareholderID, Assets1 + Assest2 + Assets3 + ... + Assets9
FROM MyTable (Yields appx. 200,000 recods)
Updates and cursors just seem to be too slow.
So far I have done the following, but was wondering if anyone could think of a better way.
SELECT 6 million records that don't need to be deleted into a #TempTable
Use statements above to select into same #TempTable
DROP and recreate Original Table
SELECT 6 + 2 million records INTO original table.
This seems rather convoluted. Is there a better approach? Would it be worth while to dump data to a file and use bcp / Bulk Insert
Any comments are appreciated,
-Marc

I receive the following error message when I try to use the Bulk Insert Task to load BCP data into a table:
Error: 0xC002F304 at Bulk Insert Task, Bulk Insert Task: An error occurred with the following error message: "Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.The bulk load failed. The column is too long in the data file for row 1, column 4. Verify that the field terminator and row terminator are specified correctly.Bulk load data conversion error (overflow) for row 1, column 1 (rowno).".
Task failed: Bulk Insert Task
In SSMS I am able to issue the following command and the data loads into a TableName table with no error messages:
BULK INSERT TableName
FROM 'C:DataDbTableName.bcp'
WITH (DATAFILETYPE='widenative');
What configuration is required for the Bulk Insert Task in SSIS to make the data load? BTW - the TableName.bcp file is bulk copy file as bcp widenative data type. The properties of the Bulk Insert Task are the following:
DataFileType: DTSBulkInsert_DataFileType_WideNative
RowTerminator: {CR}{LF}
Any help getting the bcp file to load would be appreciated. Let me know if you require any other information, thanks for all your help.

I'm trying to use Bulk insert for the first time and getting the following error. I think it might have something to do with my Format File and from the error msg there's a conversion error for the first column. In my database the Field is nvarchar(6) so my best guess is to use SQLNChar for the first column. I've checked the end of each line is CR LF therefore the is correct for line 7 right?
Msg 4863, Level 16, State 1, Line 1
Bulk load data conversion error (truncation) for row 1, column 1 (ASXCode).

Hi~,
Before implementing memory based bulk copy insert with IRowsetFastLoad interface of SQL Server 2005 OLE DB provider, I want to know some considerations.
- performance : compared with T-SQL's "BULK INSERT ..." and bcp utility
- SQL Server's resource usage : when running memory based bulk copy, server resource's influence
- server side action(behavior) : when server is busy, delayed-update means IRowsetFastLoad::Commit(true) method can insert right after?
- row-count : The rowcount limitation can be inserted by IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit
- any other guide lines

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.

Hello,
I am wondering is the Transaction Log logged differently between BULK INSERT vs INSERT? Performance speaking, which operations is generally faster given the same amout of data inserted.

Hi~, I have 3 questions about memory based bulk copy.
1. What is the limitation count of IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit(true)?
For example, how much insert row at below sample?(the max value of nCount)
for(i=0 ; i<nCount ; i++)
{
pIFastLoad->InsertRow(hAccessor, (void*)(&BulkData));
}
2. In above code sample, isn't there method of inserting prepared array at once directly(BulkData array, not for loop)
3. In OLE DB memory based bulk copy, what is the equivalent of below's T-SQL bulk copy option ?
BULK INSERT database_name.schema_name.table_name FROM 'data_file' WITH (ROWS_PER_BATCH = rows_per_batch, TABLOCK);
-------------------------------------------------------
My solution is like this. Is it correct?
// CoCreateInstance(...);
// Data source
// Create session
m_TableID.uName.pwszName = m_wszTableName;
m_TableID.eKind = DBKIND_NAME;
DBPROP rgProps[1];
DBPROPSET PropSet[1];
rgProps[0].dwOptions = DBPROPOPTIONS_REQUIRED;
rgProps[0].colid = DB_NULLID;
rgProps[0].vValue.vt = VT_BSTR;
rgProps[0].dwPropertyID = SSPROP_FASTLOADOPTIONS;
rgProps[0].vValue.bstrVal = L"ROWS_PER_BATCH = 10000,TABLOCK";
PropSet[0].rgProperties = rgProps;
PropSet[0].cProperties = 1;
PropSet[0].guidPropertySet = DBPROPSET_SQLSERVERROWSET;
if(m_pIOpenRowset)
{
if(FAILED(m_pIOpenRowset->OpenRowset(NULL,&m_TableID,NULL,IID_IRowsetFastLoad,1,PropSet,(LPUNKNOWN*)&m_pIRowsetFastLoad)))
{
return FALSE;
}
}
else
{
return FALSE;

I have two SSIS packages that import from the same flat file into the same SQL 2005 table. I have one flat file connection (to a comma delimited file) and one OLE DB connection (to a SQL 2005 Database). Both packages use these same two Connection Managers. The SQL table allows NULL values for all fields. The flat file has "empty values" (i.e., ,"", ) for certain columns.
The first package uses the Data Flow Task with the "Keep nulls" property of the OLE DB Destination Editor unchecked. The columns in the source and destination are identically named thus the mapping is automatically assigned and is mapped based on ordinal position (which is equivalent to the mapping using Bulk Insert). When this task is executed no null values are inserted into the SQL table for the "empty values" from the flat file. Empty string values are inserted instead of NULL.
The second package uses the Bulk Insert Task with the "KeepNulls" property for the task (shown in the Properties pane when the task in selected in the Control Flow window) set to "False". When the task is executed NULL values are inserted into the SQL table for the "empty values" from the flat file.
So using the Data Flow Task " " (i.e., blank) is inserted. Using the Bulk Insert Task NULL is inserted (i.e., nothing is inserted, the field is skipped, the value for the record is omitted).
I want to have the exact same behavior on my data in the Bulk Insert Task as I do with the Data Flow Task.
Using the Bulk Insert Task, what must I do to have the Empty String values inserted into the SQL table where there is an "empty value" in the flat file? Why & how does this occur automatically in the Data Flow Task?
From a SQL Profile Trace comparison of the two methods I do not see where the syntax of the insert command nor the statements for the preceeding captured steps has dictated this change in the behavior of the inserted "" value for the recordset. Please help me understand what is going on here and how to accomplish this using the Bulk Insert Task.

Hi,I've a SP that insert records in one table and then call another insert SP on a second table. The first table is like a master table and the second is like a child table. After inserting the right record in the master table, I've to insert some record in the child table. This records differ each other only by two of about ten field, so what I'd want is not to call the second SP X times, but only one time.. Is it possible??ExampleTable1: Id (identity), Desc;Table2: Id (identity), Id_table1, Id_TableX, Num, Field1, Field2, ... Field10.In Table2 only Id_TableX and Num change every time... the other are all the same (for one record in Table1). How can I do? Probably with a bulk insert and a bulk update?? But, can I make a bulk xxx without a file??

Hi,
I want to move data from a text file to a SQL table. After DTS creates the table, does it use Bulk Insert to copy the data from the file to the table, or BCP?
Thanks,

I am trying to do a bulk insert from a data file into a linked access database. When I run the query I get the error message:
'Server: Msg 4801, Level 16, State 81, Line 1
Bulk_main: The opentable system function on BULK INSERT table failed.
Not sure what the problem is because BOL just says to check Microsoft.com for updated error message information. However, when I went to the site there was no updated information. Has anyone else seen this error? If so, have you figured out the problem? Any help would be greatly appreciated. Thanks.

Hi,
Which is a faster method -- bulk insert or BCP
And I assume DTS has no problem handling either one? The input files are between 400 meg and 1 gig.

We've been using Bulk Insert to load our tables. But, recently we encountered this error message "There is insufficient system memory to run this query. [SQLSTATE 42000] (Error 701). The step failed."
Then, our DBA suggested that we use BCP. It seems to work fine until the file size exceeds 30MB. This is the message I get "Starting copy... 0 rows copied. Network packet size (bytes): 4096 Clock Time (ms.): total 14984. Process Exit Code 0. The step succeeded." Is this a known problem?
Then, we decided to use DTS. DTS seems to be able to handle any file size but it's a slower process than the other 2. Any suggestions?

I often encountered to insert multiple records into a certain table, such as:
DESCRIPTION AMOUNT
SALARY 8000
ALLOWANCE 100
CASH GIFT 400
FOOD ALLOWANCE 460
SCENARIO:
I want to insert at one time the example written above into TBLcompensation table with the following fields,
ID(identity,1), DESCRIPTION ,AMOUNT
QUESTION:
Is there other ways to INSERT multiple records at one time?
MY SOLUTION:
I collected all records and concatenated it as one string with a special character separating between fields and rows. Then i do the looping on the STORE PROCEDURE. I believe this is not an effecient way.

Hi,
Does anyone know if it is possible when using SQL Bulk Insert or BCP will allow for a variable number of columns in the input csv file? Or is it a requirement for these two commands to have a fixed number of cols in the input file?
I'm using Bulk Insert with fieldterminator = '","' and rowterminator = '' for the delimited csv file, but my input file does not have a fixed number of cols, and is not padded out with the appropiate number of empty ",".
Is there a way around this?

Hi,
I am trying to do the data transfer using BULK INSERT from a dat file. And the data is only one row .
The bulk insert is giving me the error
"Bulk insert data conversion error (truncation) for row 1, column 11 (extension1)"
The line given below is that data as it appear in the dat file.
'20030715','Logiciel','Taching, Inc.','108 Pierson Ave',,'Edison','NJ','08837','USA','732-603-7877',,,,,,,,,,,,,,,,,,,,'N','N','N','N','N','N',, ,2003/jul/15 11:09:33.718000,,,,
And that column 11(name of that column is extension1) has no data and the datatype in SQL server for that column is varchar(1).
I am not able to figure out why this error. Can anyone help.
