sqlbulkcopy

问题 I'm trying to use SqlBulkCopy to copy data into an SQL database table however it is (wrongly) saying that the columns don't match. They do match. If I use a breakpoint to see the names of the columns being mapped, they're correct. The error message shows the name of the column, and it is correct. This is my method. I have an identical method that does work and the only difference is where it gets the column names from. The strings containing the column names, however, are EXACTLY identical.

问题 I'm using SqlBulkCopy to import records from a spreadsheet into a SQL Server database. The bulk copy operation works fine under most conditions. However it's doing something I can't get my head around. I have a column defined in my column mappings: bCopy.ColumnMappings.Add("Amount", "Amount"); In the spreadsheet this is a varchar, as it is in my work table (I import to a work table to do some validation before I move the data to my live table). While I was testing, I went into a record and

Each rows contains the data needed to be inserted into the database. A sample of a row is as follows: 0001--------SCOMNET--------0.100---0.105 At first glance, one might figured that each column was separated with a tab but actually each column was separated by blank spaces (I used '-' to denote as blank spaces because somehow could not get SO text editor to

问题 I'm trying to find a better and faster way to insert pretty massive amount of data(~50K rows) than the Linq that I'm using now. The data I'm trying to write to a local db is in a list of ORM mapped data serialized and received from WCF. I'm keen on using SqlBulkCopy, but the problem is that the tables are normalized and are actually a sequence or interconnected tables with one-to-many relationships. Here's some code that illustrates my point: foreach (var meeting in meetingsList) { int

问题 I have quite a few datatable to bulkinsert into databasetable Due to large size, one table took 5 min to complete insert. 2 tables took me 10 min static void Main(string[] args) { DataTableBulkInsert(DataTable1); DataTableBulkInsert(DataTable2); } public static void DataTableBulkInsert(DataTable Table){ SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(myConnection); sqlBulkCopy.DestinationTableName = "dbo.DatabaseTable"; myConnection.Open(); sqlBulkCopy.WriteToServer(Table); myConnection.Close(); }
