从C＃批量插入Access数据库？

Question

How can I do this. I have about 10000 records in an an Excel file and I want to insert all records as fast as possible into an access database?

Any suggestions?

Answer 1

What you can do is something like this:

    Dim AccessConn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Test Files\db1 XP.mdb") 
    AccessConn.Open() 
    Dim AccessCommand As New System.Data.OleDb.OleDbCommand("SELECT * INTO [ReportFile] FROM [Text;DATABASE=C:\Documents and Settings\...\My Documents\My Database\Text].[ReportFile.txt]", AccessConn) 
    AccessCommand.ExecuteNonQuery() 
    AccessConn.Close() 

Switch off the indexing on the affected tables before starting the load and then rebuilding the indexes from scratch after the bulk load has finished. Rebuilding the indexes from scratch is faster than trying to keep them up to date while loading large amount of data into a table.

If you choose to insert row by row, then maybe want to you consider using transactions. Like, open transaction, insert 1000 records, commit transaction. This should work fine.

Use the default data import features in Access. If that does not suit your needs and you want to use C#, use standard ADO.NET and simply write record-for-record. 10K records should not take too long.
