sqlserver


create proc Stu
@sname varchar(100) 
as 
begin
select name,age from
 
 student where [email protected]
end
go

exec Stu 'tom'

jfinal中 連線sqlserver

C3p0Plugin cp = new C3p0Plugin(getProperty("url"), getProperty("user"), getProperty("kwd"), getProperty("driverclass"));   
        me.add(cp);

        // 配置ActiveRecord外掛
        ActiveRecordPlugin arp = new ActiveRecordPlugin(cp
 
);

        me.add(arp);

        arp.setDialect(new SqlServerDialect());
         arp.setContainerFactory(new CaseInsensitiveContainerFactory());  
        arp.addMapping("student", Student.class);

使用java下的jre，而不是jdk中的jre，使用tomcat，不使用jetty

create proc Stu
@sname varchar(100) 
as 
begin
select name,age from
 
 student where [email protected]
end
go

public class Exec implements ICallback{

    @Override
    public Object call(Connection conn) throws SQLException {

         PreparedStatement stmt = conn.prepareStatement("{call dbo.Stu(?)}");
         stmt.setString(1, "tom");
          ResultSet rs = stmt.executeQuery();

          while (rs.next()) {
             System.out.println(rs.getString("age"));
          }
          rs.close();
          stmt.close();
        return null;
    }

}

在controller中

public void index()
    {
    Db.execute(new Exec());
    }

create proc CheckAge
@sname varchar(100) 
as 
begin
if ((select age from student where [email protected])>20)
return 1
else
return 0 
end
go

public class ReturnState implements ICallback {

    @Override
    public Object call(Connection conn) throws SQLException {
        // TODO Auto-generated method stub
        CallableStatement csmt = conn.prepareCall("{?=call dbo.CheckAge(?)}");
        csmt.registerOutParameter(1, java.sql.Types.INTEGER);
        csmt.setString(2, "tom");
        csmt.execute();
        System.out.println(csmt.getInt(1));
        return null;
    }

}

create proc IsExist
@sname varchar(100),
@IsRight int output 
as 
begin
if exists (select name,age from student where [email protected])
set @IsRight=1
else
set @IsRight=0 
end
go

public class ReturnCallBack implements ICallback{

    @Override
    public Object call(Connection conn) throws SQLException {
        CallableStatement callableStatement = conn.prepareCall("{call dbo.IsExist(?,?)}");

        callableStatement.setString(1, "tom");
        callableStatement.registerOutParameter(2, java.sql.Types.INTEGER);

        callableStatement.execute();

        System.out.println(callableStatement.getInt(2));

        return null;
    }

}

sqlserver 觸發器

create trigger bbq 
on tb_Money
after update
as begin 
select * from tb_Money
end 

sqlserver中使用事務

CREATE PROC ONETWOCCC 
AS
BEGIN TRAN 
update tb_Money set MyMoney = MyMoney - 30 where name = N'劉備'
update tb_Money set MyMoney = MyMoney + 30 where name = N'關羽'
if @@error<>0 
BEGIN
 ROLLBACK TRAN 
PRINT '有錯誤，回滾';
END
ELSE
BEGIN COMMIT TRAN
PRINT '執行成功'
END
GO

EXEC ONETWOCCC 

jfinal中使用事務

public void roll()
    {
        boolean succeed = Db. tx(new IAtom(){
            public boolean run() throws SQLException {
            int count = Db. update("update student set sex = sex+1 where id=2");
            int count2 = Db. update("update student set sex = sex+3 where id=31");
            return count == 1 && count2 == 1;
            }});
    }

    @Before(Tx.class)
    public void as()
    {

        int i = Db.update("update student set sex = sex+1 where id=2");
        int s = Db.update("update student set name = null where id=31");

        renderText(s+"");

    }

個人更推薦第一種
