How do you prevent this:"If you import a very large number of rows, dividing the data into batches can offer advantages. After each batch complete, the transaction is logged. If, for any reason, a bulk-import operation terminates before completion, only the current transaction (batch) is rolled back." How can I let the whole batch rollback, instead only the current transaction (batch) rolling back?

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.
I have a table with 370 million rows and 50+ columns. I need to change the data type of a column from character to numeric. Here's what it contains:
40 million with numbers I want to keep, the rest I just want to set to null:
4k with alpha characters
55 million other numbers
275 million empty strings
An alter column statement fails not just on the alpha characters but on the empty strings. So I tried a couple things on a test database to get an idea of the time it would take:
An update statement to clear out the non-numeric data is too slow (~1.5 days, batched 10000 at a time). I think I probably should create a new column anyway though, so I'm going to copy the data to a new table since it would be faster than adding a new column to the original table.
An insert ... select ... takes about 12 hours; adding WITH (TABLOCK) didn't seem to have any effect, and I'm not sure how to batch it. Recovery model is simple.
A select ... into ... only takes about 1 hour, but can't be batched.
Using a 3rd party ETL tool takes about 5 hours, batched.
I wanted to batch it to minimize impact on other queries but primarily the logs. Is there any way to do a fast batched bulk transfer within SSMS?
I've got a table with a unique column, "id". I've got the id values of about 300,000 records. These records need to be DELETEd from this table. Is there a way to do this in batch? I can't imagine the only way to do it is:
DELETE FROM Table WHERE id = 1 OR id = 2 OR id = 3... OR id = 300000
Does anyone know how to do a bulk insert using just the script task? I've been searching everyehere but can't seem to find a sample.
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!
Hi, folks:
View 18 Replies View RelatedI 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,

In another forum post, a poster was deleting large numbers of rows from a table in batches of 50,000.
In the bad old days ('80s - '90s), I used to have to delete rows in batches of 500, then 1000, then 5000, due to the size of the transaction rollback segments (yes - Oracle).
I always found that increasing the number of deleted rows in a single statement/transaction improved overall process speed - up to some magic point, at which some overhead in the system began slowing the deletes down, so that deleting a single batch of 10,000 rows took more than twice as much time as deleting two batches of 5,000 rows each.
good rule-of-thumb numbers (or even better, some actual statistics and/or explanations) as to how many records should be deleted in a single transaction/statement for optimum speed? 50,000 - 100,000 - 1,000,000 or unlimited? Are there significant differences between 2008, 2012, 2014?
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?

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.

Hi,
I am in the middle of writing a console application that acquires data from dynamic odbc connections and inserts the results into a MSSQL database. I'm currently using a datareader to generate multiple calls to a stored procedure and batch execute them by means of a simple counter; this works fine.
However, I'm a little concerned that it seems to take so long to execute the sql stored procs and was wondering if anyone may know of any methods to help speed it up either on the app side or sql, or both.
I had a quick word with our dba who spoke briefly about some kind of process where by the application fires the request across to the database and carries on leaving the db to queue the request or something to that effect. He ran away before I could get any sort of sense out of him.
Any help greatly appreciated
Thanks
I'm using MS JDBC driver to connect to SQLServer 2005 and trying to perform batch insert. Here is the code i'm using:
Code Snippet

// Assume we have a valid con
con.setAutoCommit(false);
// this is the simplified SQL for the purposes of this example
StringBuffer sql = new StringBuffer();
sql.append("INSERT INTO temp_batchOpt (");
sql.append("temp)");
sql.append(" VALUES (?)");
PreparedStatement insertStatement =
con.prepareStatement(sql.toString(),
SQLServerStatement.RETURN_GENERATED_KEYS);
for (int i = 0; i < 10; i++) {
insertStatement.setInt(1,3);
insertStatement.addBatch();
}
int[] r = insertStatement.executeBatch();
// the correct number of insertions are made
if(r != null)
for(int x: r)
System.out.println("inserted "+x);
SQLServerResultSet keyRS = (SQLServerResultSet)insertStatement.getGeneratedKeys();
while (keyRS.next()) {
int id = keyRS.getInt(1);
System.out.println("**filling id ="+id);
}
con.commit();
} catch (BatchUpdateException bue) {
bue.printStackTrace();
}
catch(SQLException sqle){
sqle.printStackTrace();
}
finally {
// close the connection...
}
I'm getting the following exception:

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;

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.
