1:首先下载sqljdbc.jar,然后配置ClassPath,然后再在工程文件中把这个(sqljdbc.jar)架包引用上,就可以开始JAVA操作之旅了
打开Eclipse,“文件”→“新建”→“项目”→“Java 项目”,项目名为Test2、
在Eclipse中,选择“窗口”→“首选项...”→“Java”→“已安装的 JRE”,选择已安装的 JRE,点击“编辑”→“添加外部”
选择%ProgramFiles%sqljdbc_1.1chssqljdbc.jar3、在Test项目的“JRE 系统库”中可以看见sqljdbc.jar,
如果没有可以右键单击项目Test→“构建路径”→“配置构建路径...”→“Java 构建路径”→“库”→“添加外部 JAR...”,
选择%ProgramFiles%sqljdbc_1.1chssqljdbc.jar4、编写Java代码,如下:
2:下面是JDBC 连接MS SQL的语句
/*
* JDBC常用写法
*/
public static ResultSet GetResultSet(String sql) {
String temp1 = "";
ResultSet rs1 = null;
try {
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String url = "jdbc:sqlserver://localhost:1824; DatabaseName=AATestDB";
String user = "sa";
String password = "123456";
Class.forName(driverName);
Connection dbConn = DriverManager
.getConnection(url, user, password);
try {
Statement stmt = dbConn.createStatement(1005, 1008);
rs1 = stmt.executeQuery(sql);
} catch (SQLException e) {
} finally {
System.out.println("------------t3----------");
}
return rs1;
} catch (Exception ex) {
System.out.println("------------t4----------");
}
return rs1;
}
/*
* JDBC调用事务
*/
public static void GetResultSet(String sql)
{
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
String url = "jdbc:sqlserver://localhost:1433; DatabaseName=AATestDB";
String user = "sa";
String password = "123456";
Connection dbConn = DriverManager
.getConnection(url, user, password);
Statement stmt = dbConn.createStatement(1005, 1008);
try {
dbConn.setAutoCommit(false);
String sql1="select * from ATable where id=1";
String sql2="select * from ATable where id=2";
stmt.executeUpdate(sql1);
stmt.executeUpdate(sql2);
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
dbConn.commit();
} catch (SQLException e) {
try {
dbConn.rollback();
System.out.println("数据回滚!");
} catch (Exception e2) {
e2.printStackTrace();
}
} finally {
dbConn.setAutoCommit(true);
}
} catch (Exception ex) {
ex.printStackTrace();
}
finally{
System.out.println("操作完毕!!");
}
}
/*
* JDBC调用事务
*/
public void AAA()
{
String sql="select * from AATable";
ResultSet rs=GetResultSet(sql);
while (rs.next()) {
String aa=rs.getString("AAFiled");
............
}
}
