Some time ago, I saw some. NET connection database in the encyclopedia, found not very full, especially Sybase and CSV two data usage, now put my connection way for everyone's reference.
Sybase (OLE DB)
First you need to install 12.5 of the OLE clients and add data source in the configuration program. Then you can use it in. Net.
provider=sybase.aseoledbprovider.2;initial catalog= database name; User id= username; data source= datasource; Extended properties= ""; Server NAME=IP address; Network Protocol=winsock; Server Port address=5000;
or create a new connection directly using. NET's fool-style.
Csv
OLE DB
Select *
From OpenDataSource (' microsoft.jet.oledb.4.0 ',
' Data source= ' c:\csv\ '; User id=admin; password=; Extended properties=text ') ... [Filename#csv]
