sqlite 建索引 ，建临时表

--SELECT * FROM sqlite_temp_master WHERE type='table' AND name='tmpCurrentCityLine';


drop table tmpCurrentCityLine;
create temporary table tmpCurrentCityLine(ID,Name);
insert into tmpCurrentCityLine(ID,Name)
select ID,Name
from tblLine where CityID=2;


drop table tmpCurrentCityPointName;
create temporary table tmpCurrentCityPointName(ID,LineID,Name,RowIndex);
insert into tmpCurrentCityPointName(ID,RowIndex)
select ID,RowIndex
from tblLinePoint
where LineID in(select LineID from tmpCurrentCityLine);


--drop index ixTmpCurrentCityLine;
create index ixTmpCurrentCityLine on tmpCurrentCityLine(ID);
--drop index ixTmpCurrentCityPointName;
create index ixTmpPoint_LineID on tmpCurrentCityPointName(LineID);
create index ixTmpPoint_Name on tmpCurrentCityPointName(Name);


--drop index ixLine;
--drop index ixLinePoint_LineID;
--drop index ixLinePoint_Name;


create index ixLine on tblLine(ID);
create index ixLinePoint_LineID on tblLinePoint(LineID);
create index ixLinePoint_Name on tblLinePoint(Name);
