【问题描述】*：
当not()中包含 OR 逻辑运算符时，查询结果与预期不符，下面已提供两个验证sql，A形式判断条件 和 B形式判断条件。

正情况下B形式，查询结果不应当包含"ItemId"为null或者为''的数据行，但实际情况却查出了包含null的数据行

正情况下A形式,查询结果 会包含"ItemId"为空字符串的记录，但实际情况却反而没有包含任何 null 或 '' 的记录。

-- 条件A形式，not((c."ItemId" is null and c."ItemId" = ''))
SELECT t.* FROM 
(
SELECT a."vehicleId" as1, a."plate" as2, a."platecolor" as3
-- ……其余列省略……
FROM TSP_BASICS."vehicle" a
INNER JOIN TSP_BASICS."vehicleType" b ON a."vehicleTypeId" = b."vehicleTypeId" AND (b."isDelete" = 0)
LEFT JOIN TSP_BASICS."xj_SpecialVehiclePriceItem" c ON to_char(a."vehicleSpec") = c."VehicleSpecification"
WHERE 
  (a."sharingCenterId" = '690055dbf3378fc6df918ad8')
  AND (a."vehicleTypeId" = '607e927cd85be606703d77b3')
  AND (((a."vehicleId") in ('20250315031','20250315033','20250315034','20250315035',)))
  AND (a."isDelete" = 0 AND a."isEnable" = 1)
  AND (b."isDelete" = 0) AND (b."costType" > 0)
  AND (not((c."ItemId" is null and c."ItemId" = '')))
  AND (b."costVehicle" > 0) AND (a."isDelete" = 0)
ORDER BY a."plate"
) t WHERE ROWNUM < 1000000;
