Question

大家好我为Microsoft SQL Server编写了以下查询。我需要将此查询转换为Oracle语法。我对Oracle语法没有任何了解。我需要你的帮助才能使这个查询在Oracle数据库上运行。我尝试了很多方法但没有返回数据。

    SELECT SISPREV_student.Stu_Id, SISPREV_student.CwId,
 SISPREV_student.Sex, SISPREV_student.Nok_Name, SISPREV_student.Nok2_Name, 
              SISPREV_student.Birth_Dt,
 SISPREV_student.Currently_Enrolled, SISPREV_student.Stu_Athlete, SISPREV_student.LivingOnCampus, 
              SISPREV_student.ImmigrationStatus,
 SISPREV_student.ScholarStatus, SISPREV_student.Stu_FirstName, SISPREV_student.Stu_MiddleName,

              SISPREV_student.Stu_LastName, SISPREV_student.Ethnicity
FROM         SISPREV_address RIGHT OUTER JOIN
                      SISPREV_student ON SISPREV_address.StudentID =
 SISPREV_student.Stu_Id LEFT OUTER JOIN
                      SISPREV_email ON SISPREV_student.Stu_Id =
 SISPREV_email.StudentID LEFT OUTER JOIN
                      SISPREV_phone ON SISPREV_student.Stu_Id =
 SISPREV_phone.StudentID
WHERE ((SISPREV_student.Stu_Id LIKE '%' + '@StudentId' + '%') OR
 ('@StudentId' = '')) AND
      ((UPPER(SISPREV_student.Stu_FirstName) LIKE '%' +
 UPPER('@StudentFirstName') + '%') OR ('@StudentFirstName' = '')) AND
      ((UPPER(SISPREV_student.Stu_MiddleName) =
 UPPER('@StudentMiddleName')) OR ('@StudentMiddleName' = '')) AND
      ((UPPER(SISPREV_student.Stu_LastName) LIKE '%' +
 UPPER('@StudentLastName') + '%') OR ('@StudentLastName' = '')) AND
      ((UPPER(SISPREV_student.Nok_Name) LIKE '%' +
 UPPER('@StudentNextOfKinName') + '%') OR ('@StudentNextOfKinName' = '')) AND 
      ((UPPER(SISPREV_address.Street) LIKE '%' + UPPER('@StudentStreet') +
 '%') OR ('@StudentStreet' = '')) AND
      ((UPPER(SISPREV_address.City) LIKE '%' + UPPER('@StudentCity') +
 '%') OR ('@StudentCity' = '')) AND
      ((UPPER(SISPREV_address.State) LIKE '%' + UPPER('@StudentState') +
 '%') OR ('@StudentState' = '')) AND
      ((UPPER(SISPREV_address.ZipCode) LIKE '%' + '@StudentZipCode' + '%'
 ) OR ('@StudentZipCode' = '')) AND
      ((SISPREV_student.Birth_Dt = CONVERT(SMALLDATETIME,'@StudentBirthDay')) OR ('@StudentBirthDay' = '')) AND 
      ((SISPREV_phone.Phone = '@StudentPhoneNumber') OR
 ('@StudentPhoneNumber' = '')) AND
      ((UPPER(SISPREV_student.Sex) = UPPER('@StudentGender')) OR
 ('@StudentGender' = ''))
GROUP BY SISPREV_student.Stu_Id, SISPREV_student.CwId,
 SISPREV_student.Sex, SISPREV_student.Nok_Name, SISPREV_student.Nok2_Name, 
              SISPREV_student.Birth_Dt,
 SISPREV_student.Currently_Enrolled, SISPREV_student.Stu_Athlete, SISPREV_student.LivingOnCampus, 
              SISPREV_student.ImmigrationStatus,
 SISPREV_student.ScholarStatus, SISPREV_student.Stu_FirstName, SISPREV_student.Stu_MiddleName,

              SISPREV_student.Stu_LastName, SISPREV_student.Ethnicity

Answer 1

以下需要更改：

((upper(sisprev_address.street) like '%' + upper('@StudentStreet') + '%')

在Oracle中||串联不是+

((upper(sisprev_address.street) like '%' || upper('@StudentStreet') || '%') or ('@StudentStreet' = ''))

如果@StudentStreet来自用户输入并且可以为空，则可以在Oracle中检查

or ('@StudentStreet' is null)

日期：

convert(smalldatetime, '@StudentBirthDay')

取决于您收到日期字符串的方式

to_date('@StudentBirthDay','some date format')

'某些日期格式'='DD-MM-YYYY'或您处理的任何格式。查找Oracle数据格式字符串。
