(1). top  ... not in  ， (2). top .... id>（max），(3).游标 

这种方法感觉比上面三种要快 ，分享一下跟好的意见

使用的是 org.springframework.jdbc.core.JdbcTemplate


limit = 25;
public List> findAll(String type, final int start, final int limit) {
StringBuilder builder = new StringBuilder();
List params = new ArrayList();//给占位符赋值
builder.append("select top " + (start + limit)//第一页，start=0 （）select top 25 * ,第二页 start=25 （select top 50 *）
+ " * from v_fulldata a where 1=1");
if (type != null && type != " ") {
builder.append(" and a.atype = ? ");
params.add(type);
}
builder.append(" order by wg13 desc;");

String sql = builder.toString();
List> list = (List>) getJdbc()
.query(sql, params.toArray(), new ResultSetExtractor() {
@Override
public Object extractData(ResultSet rs)
throws SQLException, DataAccessException {
List> list = new ArrayList>();
while (rs.next()) {  //将查询结果循环
if (rs.getRow() continue;
}
Map row = new HashMap();
ResultSetMetaData rsmd = rs.getMetaData();
for (int i = 1; i row.put(rsmd.getColumnName(i), rs.getString(i));
}
list.add(row);
}
return list;
}
});
return list;
}
