VB/ASP数据库连接字符串示例

使用DSN的数据库连接字符串例:

MS SQL / MySQL / PostgreSQL

"DSN=dsnname"

 

不使用DSN数据库连接字符串例:

MS Access

通过OLEDB:

"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:somepathmyDb.mdb;"

MS SQL

通过ODBC:

"Driver={SQL Server}; Server=MyServerName; Database=myDatabaseName; UID=myUsername; PWD=myPassword"

With OLEDB (Recommended):

"Provider=sqloledb; Data Source=myServerName; Initial Catalog=myDatabaseName; User Id=myUsername; Password=myPassword"

MySQL

通过ODBC:

"Driver={MySQL ODBC 3.51 Driver}; Server=servername; Database=dbname; UID=username; PWD=password; Option=3"

PostgreSQL

通过ODBC:

"Driver={PostgreSQL}; Server=servername; Database=dbname; UID=username; PWD=password"

 

对于MS Access数据库来说，因为Access数据库的ODBC驱动程序会导致不稳定 ，所以最好不要通过DSN来连接。
