ecshop中常用的sql语句

1.获取单条记录
 $row = $GLOBALS['db']->getRow($sql);

2.获取单一字段
 $row = $GLOBALS['db']->getOne($sql);
   查询产品总数
 $num = $GLOBALS['db']->getOne(‘SELECT COUNT(*) FROM ‘ . $GLOBALS['ecs']->table(‘goods’) ;

3.获取所有记录
 $row = $GLOBALS['db']->getAll($sql);

4.执行sql语句
 $res = $GLOBALS['db']->query($sql);

//执行删除(DELETE),插入(INSERT),更新(UPDATE)等操作可用此方法

5.把数组元素插入数据库

    $parent['goods_number'] = ’1′;

    $parent['parent_id'] = 0;

    $GLOBALS['db']->autoExecute($GLOBALS['ecs']->table(‘cart’), $parent, ‘INSERT’);
