Java Database connection--jdbc-odbc Bridge connection mode

JDBC-ODBC Bridge Connection mode operation database SU (Course)

Steps:

1. Configure the data source

Control Panel Search Administration Tool->ODBC Data Source (32-bit), add, select SQL Server (fill in name mytest, Server local or.) Next, change the default database to su-> Next, test data source to success

The user data source will have one more mytest to configure the data source successfully.

2. Connect to the data source in the program

Open Eclipse and write the program.

Load Driver (function: Add the required driver to the memory)9Class.forName ("Sun.jdbc.odbc.JdbcOdbcDriver");Ten              One             //2. Get Connected (specify which data source to connect to) A             //If you select Windows NT Authentication when you configure a data source, you do not need a user name and password -             //If you select user authentication, you need to add a username and password -Ct=drivermanager.getconnection ("Jdbc:odbc:mytest"); the          -             //3.

Execute (crud, create DATABASE, back up database, delete data ...) -             //Demo Adds a piece of data to the course table, executeupdate can perform add delete and modify operations +             intI=sm.executeupdate ("INSERT into Course values (' 8 ', ' Software test ', 4, 3)"); A              at             if(i==1) { -System.out.print ("Add Success"); -}Else { -System.out.print ("Add unsuccessful"); -             } -              in}Catch(Exception e) { - e.printstacktrace (); to}finally{ +             //Close Resources!!! The order is who is created after the first close -             Try { the                 if(sm!=NULL){//The IF statement is for the robustness of the program * sm.close (); $                 }Panax Notoginseng                 if(ct!=NULL){ - ct.close (); the                 }         +}Catch(SQLException e) { A e.printstacktrace (); the             }         +         } -     } $}

Executes the program and the console output is added successfully.

Open SQL server2012 to view the course table of the SU database, and indeed one more data, the operation succeeds.
