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
Similar to a previous post (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=244646&SiteID=1), I am trying to import data into a SQL Table.
I am trying to program a small application that will import product data obtained through suppliers via CD-ROM. One supplier in particular uses Fixed width colums, and data looks like this:
Example of Data
0124015Apple Crate 32.12
0124016Bananna Box 12.56
0124017Mango Carton 15.98
0124018Seedless Watermelon 42.98 My Table would then have: ProductID as int Name as text Cost as money
How would I go about extracting the data with an XML Format file? I am stumbling over how to tell it where to start picking up data for a specific column. Is there any way that I could trim the Name column (i.e.: "Mango Carton " --> "Mango Carton")?
I don't know if it makes any difference, but I've been calling SQL from my code by doing this:
Code in C# Form
SqlConnection SqlConnection = new SqlConnection(global::SQLClients.Properties.Settings.Default.ClientPhonebookConnectionString); SqlCommand cmd = new SqlCommand();
SqlConnection.Open(); cmd.ExecuteNonQuery(); SqlConnection.Close(); RefreshData(); I am running Visual Studio C# Express 2005 and SQL Server Express 2005.
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
I have imported an event log file from an NT server in a test database . The table has been created automatically with some 10 columns as Col001...Col002 ...and so on till Col0010 . Now i want to copy the data of the event logs to specific columns . So i created a table with name such as Evnt , date , time , server and evntdescription so that whenever i can execute a simple query like
Select * from tablename where type = 'app' , Server = 'test1 ' . so that i get all the results for that server 'test1 with type 'application' .
The problem is how do i insert that event log file into the table which i have created with different columns names . So that the data with 'App' should go to column 'type , data with server name should go to the column name server and so on ..
I tried all the was but could not succeed . Can i get some help in this regard please through some stored procedures or through DTS , if its possible .
I import a group of sentences INSERT from a text file .... test
Insert Into XXXXX Values('UUUUUU','3') Insert Into XXXXX Values('UUUUUU','3') Insert Into XXXXX Values('UUUUUU','3') Insert Into XXXXX Values('UUUUUU','3') Insert Into XXXXX Values('UUUUUU','3') Insert Into XXXXX Values('UUUUUU','3') Insert Into XXXXX Values('UUUUUU','3') Insert Into XXXXX Values('UUUUUU','3')
The file contains 1000 insert (Aprox); I read lines for lines the file I make the insert
In VS.NET 2003 it works correctly and the process consumes little memory but In VS.NET 2005 the pocket is without space.
How I can specify the factor of growth of the database SQL Mobile?
I would appreciate some help on a procedure that I have. Using BulkInsert, I would like to import records from a text file. The issue Ihave is the file contains a header - '1AMC_TO_Axiz' and a footer'1AMC_TO_Axiz2". Using a format file, I can get the import to work byediting the file and removing these two entries. Is there a way tosetup the format file to skip these two entries? My file currentlylooks like this:7.0161 SQLCHAR 0 50 "|" 1 keyMemberNo2 SQLCHAR 0 10 "|" 2 fldEffdate.................16 SQLCHAR 0 10 " " 16 fldNewRecordThanksCharles
Hello I need to write a proc to load data from txt files I receive into a table. It works fine when I specify bulk insert.... from 'myfilename.txt' BUT my filename will always change and I store it into a variable @filename
When I try to run the bulk insert instruction ... from @filename it doesn't work.. do you know why?
I am trying my first bulk update to an existing SWL table from a CSV text file,The text file naming is exacrtly the same as the SQL table, with the same attributes
The statements: BULK INSERT [Jedox_prod].[dbo].[B_BP_Customer] FROM 'c:Baanjedox_dailyjdcom4401.txt' WITH
[code]....
The error message is: [size=1Msg 4864, Level 16, State 1, Line 1
Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 2, column 3 (BP_Country). Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error. Msg 7330, Level 16, State 2, Line 1
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".size=1]..The have checked and re-checked the BP_Country field ( the 1st field after the key) and I am not seeing any mismatches.
OK, Ive read many posts on this problem but have seen no resolution.
Here's the deal. When on the actual SQL box (There's 2 in the cluster) the bulk insert works fine. No errors and the event log on the machine that is hosting the text file shows that the account that SQL runs on has accessed the file. This account is a DOmain account and is in the Local Administrator of the SQL server and the remot box hosting the text file.
Thats great if you want your developers testing and accessing your SQL box as Administrators. We don't work that way. Our developers connect via SQL Management Studio and test ther stuff that way. That's where the problem rears it's ugly head.
When anyone runs a Bulk Insert command that accesses a text file that is on a remote server, they get an "Access Denied". Now, I did a lot of testing and found that when the users executes the Bulk Insert command from the SQL Management studio on their desk top, they connect to the SQL box with their credentials (OK, that's correct right?), SQL then runs the Bulk Isert command which then reaches out to the remote file server but gets the "Access Denied". I check the logs and it shows that "Anonymous" was trying to accesss the file.
Why is Anonymouss coming over as credentials for SQL on a Bulk Insert? I'm no idiot but this sounds like a big crappy bug tha M$ will not fess to. I followed many suggestions, made sure NTFS and Share level permissions were correct (That was the first thing...), made sure the account that was running as SQL Server within the cluster on both nodes in the cluster was the same, that wasn't it, I even created a SPN for SQL to run and automatically register in AD with the credentials that SQL runs as. NOTHING!!!
Has anyone gotten their bulk insert to work when inserting from a file that is NOT local to the SQL box? Any help is appreciated, but putting the text files on the local SQL box IS NOT AN OPTION.
I am new to SSIS but i have avg working knowledge in sql. My problem is as follows ,I have a text pipe dilimited file in some folder and the number of columns and the name of the column is not consistant. It can have N number of column and it can have any column names. I need to load this text file data into a sql table. All that i want is to load this file to SQL Database with some temp name. Once i get the table in SQL Database, i can match the column names of both taget table and this temp table and only push those column which matches with the target table. For this i can frame Dynamic SQL. This part is clear to me.
Now the problem is , I developed a SSIS pacakge to push the text file to SQL Table. I am able to do this. But if i change the column names or added new column SSIS is not able to push the new columns. Is this functionality available in SSIS, is it can be dynamic like this?
I hope i am clear with my prob... if need any clarification please let me know
I am using Microsoft SQL 2005, I need to do a BULK INSERT from a .csv I just downloaded from paypal. I can't edit some of the columns that are given in the report. I am trying to load specific columns from the file.
bulk insert Orders FROM 'C:Users*******DesktopDownloadURL123.csv' WITH ( FIELDTERMINATOR = ',', FIRSTROW = 2,
ROWTERMINATOR = '' )
So where would I state what column names (from row #1 on the .csv file) would be used into what specific column in the table.
I saw this on one of the sites which seemed to guide me towards the answer, but I failed.. here you go, it might help you:
FORMATFILE [ = 'format_file_path' ]
Specifies the full path of a format file. A format file describes the data file that contains stored responses created using the bcp utility on the same table or view. The format file should be used in cases in which:
The data file contains greater or fewer columns than the table or view.
The columns are in a different order.
The column delimiters vary.
There are other changes in the data format. Format files are usually created by using the bcp utility and modified with a text editor as needed. For more information, see bcp Utility.
we can easily load a file into db tables. However, my main concern here is the number of columns in the file. A text file TEXT_1400.txt has 1400 columns. I am unable to load data to my db table using BCP or BULK INSERT commands, as maximum of 1024 columns are allowed per table in SQL Server 2008.
We can still go ahead and create ‘Wide Table’ (a special table that holds up to 30,000 columns. The maximum size of a wide table row is 8,019 bytes.). But when operating on wide table, BCP/BULK INSERT commands still fail. After few hours of scratching my head over BCP and BULK INSERT, I observed that while inserting BCP/BULK INSERT commands are unable to identify SPARSE columns and skip these columns, which disturbs column mapping and results in data conversion and trancation errors.
Is there any proper way to load this kind of files into the db table?
I have a question...As per my knowledge bulk copying is not possible during the backup operation. If backup starts first backup will go and bulk copy will fail or bulk copy starts first backup fails and bulk copy will continue... Today I was testing bcp to run in dts using the EXCUTE PROCESS TASK (with this task we run any Win32 Excutable or batch file). I am trying to bcp out from one database(source) and bcp in to another database(destination). While running this package backup also running... I have started the database (destination) backup job and it was running and I started another job to run the dts (even I ran dts manually). Both the josbs succeeded and inserted the data into the table.... Can any one shed some light on this ....
I want to bulk copy a table using 'SELECT INTO' from a database in server1 to a database in server2. The 'FROM' part of the select into only allows three parameters 'database, user & table' within the the one server.
I remember seeing some option that allows one to bulk copy across servers but cant find it ?????
hi , I am using command line for bulk copy operation. I do have a couple of tables with some triggers to move data from one table to another on an insert trigger, I was just wondering, Is those triggers going to fire when I import data into the tables using bcp command line?
I am doing a full snapshot on couple of subcriptions but getting this message from last couple of days. I have to do this at night because tables are very large so it does not block the users. I am not sure which table this error is happening. It used to work fine but from last couple of days this has started to happen. I need to re-sync my subscription database with production database but some of the tables are giving problem.
The process could not bulk copy out of table '[dbo].[syncobj_0x3735393934363031]'.

Can I still use bcp comman to export data into a table when the target table has a referential integrity with another table ( parent child relationship ) .. thanks
I have a bcp which generates .txt file perfectly. I just wanted to know how can i generate a text file in distributed environment.
Assuming that my Sql Server is running in machine A. I wanted the bcp to generate in Machine B. What are the permission's i should give in order to generate it in Machine B.
Server: Msg 7399, Level 16, State 1, Line 1 OLE DB provider 'STREAM' reported an error. The provider did not give any information about the error. The statement has been terminated.
i am beginner in .NET visual programming using C#.NET with SQL Server 2005
i am facing a problem in SQL Server. suppose I have a table given below.. ------------------------------------------------ Table name is "A" ------------------------------------------------ 1 Michle Administrator 2 John Consumer Finance Officer 3 Jackson Employer 4 Goeffery Empl0yer
------------------------------------------------ Here the identity column is the first one. Now if i delete the 2nd row the this table becomes like that ------------------------------------------------ Table name is "A" ------------------------------------------------ 1 Michle Administrator 3 Jackson Employer 4 Goeffery Empl0yer
------------------------------------------------
Now i have an another table "B" having same structure (3 columns and first column is the identity column). Now if i move the all the data from table "A" to table "B" then the original seqeunce is distrubed the table "B" contains the data like this.
------------------------------------------------ Table name is "B" ------------------------------------------------ 1 Michle Administrator 2 Jackson Employer 3 Goeffery Empl0yer
------------------------------------------------
but i need that what ever the first column is identity column but sequence of numbering must be same as the numbering in the table "A" to preserve the relationships.... like that...
------------------------------------------------ Table name is "B" ------------------------------------------------ 1 Michle Administrator 3 Jackson Employer 4 Goeffery Empl0yer
------------------------------------------------
waiting for ur responce. i will very thankful to you to solve my problem.
Note:- the is moved using SQLBULKCOPY command.....
We have bulk copy option enabled for our DB and we really use it. Will it be possible to set up a snapshot replication over the Internet of particular tables to a remote server from which the data will be only retrieved and never changed? Also, is it necessary to have PKs in all tables for this one-way snapshot replication? (for transactional replication it is needed, as I know)
I am working on sql server bulk copy program. I am getting data files from our vendors for shares and stocks. The data files are pipe separated values. for ex the Ascii file format is
8388182|"ACC consultanats"|"rating for the current financial year"|23
My doubt is i have four columns in my sql server table named stocks.
In this the third column named memo1 in the data file would be a large volume data. That is it may be upto one full A4 size page. One important thing is, data in the third column is not formatted.
Since it is very urgent, let me know what would be the format file for this type of data file and the bulk copy program utility.
