Connecting various database string connection programs in asp.net (mysql/mssql/access) (1/2)

I have added my favorite database string connection programs, including mysql, mssql, and access. You can also send other programs.

MSSQL connection string

(1) OLEDB
Windows Authentication

The Code is as follows:	Copy code
& Quot; Provider = SQLOLEDB; Data Source = PEK7-6TKX23XSQLEXPRESS; Initial Catalog = Test; Trusted_Connection = Yes; & quot ;"; SQL Server Authentication "Provider = SQLOLEDB; Data Source = 127.0.0.1SQLEXPRESS; Initial Catalog = Test; User Id = sa; Password = 123456 ;";

(2) SqlConnection
Windows Authentication

The Code is as follows:	Copy code
"Data Source = PEK7-6TKX23XSQLEXPRESS; Initial Catalog = Test; Trusted_Connection = Yes ;"; SQL Server Authentication "Server = 127.0.0.1SQLEXPRESS; database = Test; Uid = sa; PassWord = 123456 ";

(3) ODBC

The Code is as follows:	Copy code
Driver = {SQL Server}; Server = Server IP address; Database = Database name; Uid = user name; Pwd = password;

(4) DSN Mode

The Code is as follows:	Copy code
DSN = DSN name; Uid = user name; Pwd = password;

 

Example: mysql example

The Code is as follows:
