Question

我需要从2个表中获取记录 procedure和procedure_user_map，我在sql服务器上编写一个查询以便根据所选的限制和偏移量获取记录从ui，我正在编写以下查询以获取记录

但是我没有得到10条记录，rownum（）函数不起作用在找到不同之后，它会将计数放在每一行

WITH MD_Results AS 
(
    SELECT P.pk, P.procedure_name,
     RowNum() OVER (order by P.procedure_name asc) AS RowNum 
    FROM "procedure" P, "procedure_user_map" PUM 
    where P.pk = PUM.procedure_fk 
) 
SELECT DISTINCT "pk", "procedure_name", RowNum FROM MD_Results 
WHERE RowNum > 0 AND RowNum <= 0 + 10

我希望获得不同的过程记录并对其执行rownum（）得到正确的计数

Answer 1

尝试这样的事情

WITH MD_Results AS 
(
    SELECT P.pk, P.procedure_name,
     RowNum() OVER (PARTITION BY P.procedure_name order by P.procedure_name asc) AS RowNum 
    FROM "procedure" P, "procedure_user_map" PUM 
    where P.pk = PUM.procedure_fk 
) 
SELECT top 10 pk, procedure_name, RowNum FROM MD_Results 
WHERE RowNum > 1

从sql server中查找不同的记录
