Sql 在FROM子句中使用“FROM”作为别名；作为「；在甲骨文中

我正在使用Oracle SQL Developer为学校创建一个数据库项目

我们有需要从数据库中检索的信息，所以我尝试编写查询来实现这一点。对于我的一个查询，我试图重命名我的FROM子句，但得到一个错误。我试着把别名放在括号里，引号里，但我还是得到了错误

有人能指出我的语法哪里出了问题吗

SELECT AvatarName AS "MegaAvName", SpeciesName AS "MegaAvSpecies", MagicName 
AS "MegaAvMagic", Hoard,
AvatarName AS "Father", SpeciesName AS "FatherSpecies", SpeciesCost AS 
"FatherSpeciesCost", WisdomName AS "FatherWisdom",
AvatarName AS "Mother", SpeciesName AS "MotherSpecies", SpeciesCost AS 
"MotherSpeciesCost", WisdomName AS "MotherWisdom"

FROM MegaAvatar AS MA, Avatar AS A, Species AS MSP, MagicPower AS MP, 
SuperAvatar AS FSA, Avatar AS FA, Species AS FSP, Wisdom AS FW,
SuperAvatar AS MSA, Avatar AS MA, Species AS MSP, Wisdom AS MW

WHERE MA.Avatar_ID=A.AvatarID AND Avatar.SpeciesID=MSP.SpeciesName AND 
MegaAvatar.MagicPowerID=MP.MagicPowerID AND A.Hoard>='16'
AND MegaAvatar.PrimParentID=FSA.SuperAvID AND FSA.AvatarID=FA.AvatarID AND 
FA.SpeciesID=FSP.SpeciesID
AND MegaAvatar.SecParentID=MSA.SuperAvID AND MSA.AvatarID=MA.AvatarID AND 
MA.SpeciesID=MSP.SpeciesID;

---

从子句中删除

表名后的
作为

table\u name alias\u name
将完成这项工作
啊，我明白了。这在甲骨文里是不允许的！谢谢你，本。我将标志管理员关闭。你应该能够同意潜在的重复ACostea和关闭它自己。请看：是的，如果您将鼠标放在AS上弯曲的粉红色线条上，您将看到我们希望您调用flashback查询子句
