Question

我有一个名为采购清单的表，该表具有县FIPS和最常用姓氏的姓氏计数。

Fips    mdLASTNAME  MOST_FREQUENT rn
37109   SMITH                           953 1
37109   JOHNSON                         496 2
37109   WILLIAMS                        376 3
37109   BROWN                           354 4
37109   WILSON                          315 8
37119   BURNS                           535 162
37119   BRADLEY                         534 163
37119   WATKINS                         531 164
37119   STEELE                          529 165
37119   BERRY                           528 166

我需要从FIPS 37109中提取953个姓氏为Smith的记录，并且 496条来自FIPS 37109的姓氏JOHNSON的记录 528条来自FIPS 37119的姓氏Berry的记录，因此没有从表中称为客户。

declare lineCursor12 cursor
fast_forward
for 
select DISTINCT FIPS from #temp5 

declare @Fips varchar(5)

open lineCursor12
fetch next from lineCursor12 into @Fips 
       while @@FETCH_STATUS=0
       begin                  
                     insert into dbo.test
                     Select * from dbo.Customer
                     where  mdFips=@Fips ORDER BY MOST_FREQUENT desc)




                     fetch next from lineCursor12 into @Fips
       end

close lineCursor12
deallocate lineCursor12

Answer 1

声明lineCursor12光标快进对于从[Workspace]中选择FIPS，[MOST_FREQUENT]，[LASTNAME]。[dric]。[EriclastName2]其中FIPS在（'37119'，'37109'）

声明@Fips varchar（5）声明@MOST_FREQUENT int 声明@LASTNAME varchar（50）

打开lineCursor12 接下来从lineCursor12获取@ Fips，@ MOST_FREQUENT，@ LASTNAME 而@@ FETCH_STATUS = 0 开始

                 set rowcount @MOST_FREQUENT
                 insert into dbo.finallastname


                 Select [aFIRSTNAME],[aMIDDLEINITIAL],[aLASTNAME],[NameCat],[aFips] from dbo.consumer
                 WITH(INDEX(IX_aLastName_aFips))
                 where aFips=@Fips and [aLASTNAME]= @LASTNAME 
                 Set rowcount 0



                 fetch next from lineCursor12 into @Fips,@MOST_FREQUENT,@LASTNAME
   end

关闭lineCursor12 取消分配lineCursor12

需要提取来自不同县的记录的可变计数
