Note: While I target Windows Phone 7, it doesn't introduce anything besides a size restriction. In an attempt to write a GPS / Routing / Map application for the Windows Phone 7, I'm trying to attempt to use OpenStreetMap for this and I want to get my data stored in a SQL Server Compact Edition database on my Windows Phone 7 . This is giving me a lot of trouble so I'm getting clueless what the right way is... Here is my progress: I've downloaded Belgium.osm.pbf , which contains all the Belgium OSM data in PBF format . Note that Belgium isn't that large, it's the country I live in so it seems as

I have created a datatable and trying to insert that datatable through SqlBulkCopy but somehow it doesn't seem to work for me.... I got the error, The given value of type DateTime from the data source cannot be converted to type decimal of the specified target column. My Datasource is, DataTable dt = new DataTable(); dt.Columns.Add(new DataColumn("EmpId", typeof(Int64))); dt.Columns.Add(new DataColumn("FromDate", typeof(DateTime))); dt.Columns.Add(new DataColumn("ToDate", typeof(DateTime))); dt.Columns.Add(new DataColumn("DaysPresent", typeof(decimal))); dt.Columns.Add(new DataColumn(

I have done some research for "The bast way to insert huge data into DB with C#" then a lot of people just suggested me using SqlBulkCopy. After I tried it out and it really amazed me. Undoubtedly, SqlBulkCopy is very very fast. It seems that SqlBulkCopy is a perfect way to insert data (especially huge data). But why dont we use it at all times. Is there any drawback of using SqlBulkCopy? Michiel Buddingh Two reasons I can think of: As far as I know, it's only available for Microsoft SQL Server In a lot of normal workloads, you don't do bulk insert s, but occasional insert s intermixed with

Below is the code I used to bulkcopy data from a temp table dataTable into a destTable in Oracle Database. The dataTable has about 2 million records. using (OracleBulkCopy bulkCopy = new OracleBulkCopy(VMSDATAConnectionString)) { try { foreach (OracleBulkCopyColumnMapping columnMapping in columnMappings) bulkCopy.ColumnMappings.Add(columnMapping); bulkCopy.DestinationTableName = destTableName; //bulkCopy.BatchSize = dataTable.Rows.Count; //bulkCopy.BulkCopyTimeout = 100; int defaultSize = 5000; int.TryParse(ConfigurationManager.AppSettings["OracleBulkCopyBatchSize"], out defaultSize); bulkCopy

I am designing an application, one aspect of which is that it is supposed to be able to receive massive amounts of data into SQL database. I designed the database stricture as a single table with bigint identity, something like this one: CREATE TABLE MainTable ( _id bigint IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED, field1, field2, ... ) I will omit how am I intending to perform queries, since it is irrelevant to the question I have. I have written a prototype, which inserts data into this table using SqlBulkCopy. It seemed to work very well in the lab. I was able to insert tens of millions

I'm looking for the fastest way to load bulk data via c#. I have this script that does the job but slow. I read testimonies that SqlBulkCopy is the fastest. 1000 records 2.5 seconds. files contain anywhere near 5000 records to 250k What are some of the things that can slow it down? Table Def: CREATE TABLE [dbo].[tempDispositions]( [QuotaGroup] [varchar](100) NULL, [Country] [varchar](50) NULL, [ServiceGroup] [varchar](50) NULL, [Language] [varchar](50) NULL, [ContactChannel] [varchar](10) NULL, [TrackingID] [varchar](20) NULL, [CaseClosedDate] [varchar](25) NULL, [MSFTRep] [varchar](50) NULL,

In our current project, customers will send collection of a complex/nested messages to our system. Frequency of these messages are approx. 1000-2000 msg/per seconds. These complex objects contains the transaction data (to be added) as well as master data (which will be added if not found). But instead of passing the ids of the master data, customer passes the 'name' column. System checks if master data exist for these names. If found, it uses the ids from database otherwise create this master data first and then use these ids. Once master data ids are resolved, system inserts the transactional
