使用方法:

 

pagerquery query = new pagerquery();
query.pageindex = 1;
    query.pagesize = 20;
    query.pk = "id";
    query.selectclause = "*";
    query.fromclause = "testtable";
    query.sortclause = "id desc";

    if (!string.isnullorempty(code))
    {
     query.whereclause.append(" and id= @id");
    }

select count(0) from testtable where 1=1 and id= @id

b) generatesql()方法產生的語句為:
with t as (select row_number() over(order by ecid desc) as row_number, * from testtable where 1=1 and id= @id) select * from t where row_number between 1 and 20

c) generatesqlincludettotalrecords()方法產生的語句為:
