怎样用DELPHI去连接DB2的数据库

1)连接Oracle 8/8i/9i/10g/11g（thin模式）

Class.forName("oracle.JDBC.driver.OracleDriver").newInstance()

String url="JDBC:oracle:thin:@localhost:1521:orcl" //orcl为Oracle数据库的SID

String user="test"

String password="test"

Connection con=DriverManager.getConnection(url,user,password)

2)连接DB2数据库

Class.forName("com.ibm.db2.jcc.DB2Driver")

String url="JDBC:db2://localhost:5000/testDb"

String user="test"String password="test"

Connection con=DriverManager.getConnection(url,user,passwo

ADOConnection1.ConnectionString := 'DSN=MS Access DatabaseDBQ=mdb文件名DefaultDir=缺省工作路径DriverId=25FIL=MS AccessMaxBufferSize=2048PageTimeout=5PWD=密码UID=admin'

例如:Access文件为db.mdb,设置密码为:hello,则:

ADOConnection1.ConnectionString := 'DSN=MS Access DatabaseDBQ=db.mdbDefaultDir=DriverId=25FIL=MS AccessMaxBufferSize=2048PageTimeout=5PWD=helloUID=admin'

无密码则为:

ADOConnection1.ConnectionString := 'DSN=MS Access DatabaseDBQ=db.mdbDefaultDir=DriverId=25FIL=MS AccessMaxBufferSize=2048PageTimeout=5PWD=UID=admin'
