SQL子查詢問題

Question

我想通過這種方式來結合這兩個查詢來確定哪些PI是擁有設備（> $ 100K值）。我有能力找到PI擁有的所有設備大於100k。我也有能力看到所有的PI。我無法將這兩個查詢合併。我已經嘗試了一個WHERE子查詢和一個EXIST子查詢。我希望能夠在查詢＃2中找到PI存在的所有設備（與其PI主人匹配）。

查找特定PI

select Account_No,Inventory_No,Building_No,Room_No,CDDEPT,Location,Normalized_MFG,Manufacturer_Name,Normalized_Model,Name,Serial_Code,CONCAT('$', FORMAT(Cost, 2)) as Cost, Equipment_Inventory_Normalized.Active 
from Temp_Equipment_Inventory.Equipment_Inventory_Normalized, `paul`.`ROOM`, `paul`.`BLDG`, `paul`.`LABORATORY`, `paul`.`PERSON` 
where (`PERSON`.`ID` = `LABORATORY`.`PI_ID` OR `PERSON`.`ID` = `LABORATORY`.`SUPV_ID`) 
AND `LABORATORY`.`RM_ID` = `ROOM`.`ID` 
AND `LABORATORY`.`ACTIVE` = '1' 
AND `ROOM`.`BLDG_ID` = `BLDG`.`ID` 
AND ((
`BLDG`.`BLDGNUM` = Equipment_Inventory_Normalized.Building_No 
AND Equipment_Inventory_Normalized.Actual_Building IS NULL 
AND (`BLDG`.`BLDGNUM` != '1023' AND `LABORATORY`.`OTHER_LEVEL` != '1' AND `ROOM`.`RMNUM` != '0199') 
)OR (
`BLDG`.`BLDGNUM` = Equipment_Inventory_Normalized.Actual_Building AND 
(`BLDG`.`BLDGNUM` != '1023' AND `LABORATORY`.`OTHER_LEVEL` != '1' AND `ROOM`.`RMNUM` != '0199') 
)) 
AND ((
`ROOM`.`RMNUM` = Equipment_Inventory_Normalized.Room_No 
AND Equipment_Inventory_Normalized.Actual_Room IS NULL 
)OR (
`ROOM`.`RMNUM` = Equipment_Inventory_Normalized.Actual_Room 
)) 
AND Equipment_Inventory_Normalized.Active !=0 
AND SurplusPending != '1' 
AND Cost >= 100000 
AND `PERSON`.`CANNUM`='810010787' 

查詢2的設備查詢＃1查找所有督察

select distinct i.CAN 
from CGWarehouse.CCGV10WC w 
inner join CGWarehouse.CCGV10IC i 
on w.PROJECT_NUMBER=i.SPONSORED_PROJECT 
and w.SEQUENCE_NUMBER=i.PROJECT_SEQUENCE 
where w.STATUS='A' 
and i.PRIN_INVEST_CODE='Y' 
and i.DEL_CODE!='Y' 
and i.CAN IS NOT NULL

也許你正在尋找的IN關鍵字的WHERE子句？

原諒我，但我不得不清理你的查詢一點點的格式......它有點強迫症我的事：
