If I run the following query in SQL Server 2000 Query Analyzer: BULK INSERT OurTable FROM 'c:\OurTable.txt' WITH (CODEPAGE = 'RAW', DATAFILETYPE = 'char', FIELDTERMINATOR = '\t', ROWS_PER_BATCH = 10000, TABLOCK) On a text file that conforms to OurTable's schema for 40 lines, but then changes format for the last 20 lines (lets say t...
I am working on a project with peek performance requirements, so we need to bulk (batch?) several operations (for example persisting the data to a database) for efficiency. However, I want our code to maintain an easy to understand flow, like: input = Read(); parsed = Parse(input); if (parsed.Count > 10) { status = Persist(parsed); ...
I need to import a large CSV file into an SQL server. I'm using this : BULK INSERT CSVTest FROM 'c:\csvfile.txt' WITH ( FIELDTERMINATOR = ',', ROWTERMINATOR = '\n' ) GO problem is all my fields are surrounded by quotes (" ") so a row actually looks like : "1","","2","","so...
I am about to start on a journey writing a windows forms application that will open a txt file that is pipe delimited and about 230 mb in size. This app will then insert this data into a sql server 2005 database (obviously this needs to happen swiftly). I am using c# 3.0 and .net 3.5 for this project. I am not asking for the app, just ...
Within SQL Server Integration Services (SSIS) there is the ability to setup a connection to a flat file that can hold millions of records and have that data pushed to a SQL DB. Furthermore, this process can be called from a C# app by referencing and using the Microsoft.SqlServer.Dts.Runtime namespace. Would a flat file with millions of...

I need to insert 20,000 rows in a single table (SQL Server 2005) using iBatis. What's the fastest way to do it ? I'm already using batch mode, but it didn't help much: try { sqlMap.startTransaction(); sqlMap.startBatch(); // ... execute statements in between sqlMap.commitTransaction(); } finally { sqlMap.endTransaction(); } ...
In a comment I read Just as a side note, it's sometimes faster to drop the indices of your table and recreate them after the bulk insert operation. Is this true? Under which circumstances? ...
I'd like to take a table, generate it's hash string, store it, then compare it at a later predefined time and see if it matches, if not take note of the modification time and store that with the new change date. This is because I believe an on insert trigger would cause a bad slow down if a batch of over 5000+ insert statements is submi...
I am trying to insert a .csv file into a database with unix linebreaks. The command I am running is: BULK INSERT table_name FROM 'C:\file.csv' WITH ( FIELDTERMINATOR = ',', ROWTERMINATOR = '\n' ) If I convert the file into Windows format the load works, but I don't want to do this extra step if it can be avoided. Any id...
Hi I'm working a project where we need to process several xml files once a day and populate a Database with the information contained in those files. Each file is roughly 1Mb and contains about 1000 records; we usually need to process between 12 and 25 of these files. I've seen some information regarding bulk inserts using NHibernate b...
How do you use a binarywriter to write the correct MS SQL native format for the Money data type? I'd like to take a value in .net, read from a file as string representation of a decimal amount (actually an exported "Money" data type from SQL, but that is unimportant). How can I use a binary writer to write the value so that you can u...
Hi, Would using bulk insert for 2000 rows of data make sense? It might be 500-2K in reality. BTW, does bulk inserts ignore constraint or is that a setting? (using sql server 2008, .net on the server side, data is coming in via a web service (wse or WCF)). ...
I have a CSV file at the client side, and I want to develop a C# application to bulk insert the data into a table of a database to minimal log output.

I would like to use SSIS to create database table flat file exports then import them in to variously distributed SQL Express installs. As you may guess, SSIS is not available in the Express version. When I do the bulk insert, it errors with: Msg 4866, Level 16, State 8, Line 1 The bulk load failed. The column is too long in the data f...
so I have an old database that I'm migrating to a new one. The new one has a slightly different but mostly-compatible schema. Additionally, I want to renumber all tables from zero. Currently I have been using a tool I wrote that manually retrieves the old record, inserts it into the new database, and updates a v2 ID field in the old ...
