SQL子查询问题

Question

我想通过这种方式来结合这两个查询来确定哪些PI是拥有设备（> $ 100K值）。我有能力找到PI拥有的所有设备大于100k。我也有能力看到所有的PI。我无法将这两个查询合并。我已经尝试了一个WHERE子查询和一个EXIST子查询。我希望能够在查询＃2中找到PI存在的所有设备（与其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' 

查询2的设备查询＃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

也许你正在寻找的IN关键字的WHERE子句？

原谅我，但我不得不清理你的查询一点点的格式......它有点强迫症我的事：

    Manufacturer_Name, 
    Normalized_Model, 
    Name, 
    Serial_Code, 
    CONCAT('$', FORMAT(Cost, 2)) AS Cost, 
    Equipment_Inventory_Normalized.Active

    Temp_Equipment_Inventory.Equipment_Inventory_Normalized a, 
    `paul`.`ROOM`,
