sqlserver 动态游标

--创建动态游标
set @sql = 'declare rowCursor cursor For select aimg,aname,aprice from ( select *, ROW_NUMBER() over('+ @order +') as rn from (select id,aimg,aname,aprice from F_Anli where '+ @where +') t ) a where rn>='+@start+' and rn<='+@end;
EXEC(@sql)
    
--打开游标
OPEN rowCursor; 
--取值
