How to insert data from same set of tables selecting different id from the same

  • I am trying to insert same set of records with student id 1234 (All 4 records with student id 1234 needs to be inserted into same table but instead of

    student id 1234. i want the id to be selected 9876)

    Below is the sample data Student ID 1234 below points to specific case from casetype table where type = 'HOLL' and Subtype = 'SUXX'

    Student ID 9876 below points to specific case from casetype table where type = 'HOLL' and Subtype = 'GEN'

    StudentID     StudentName       StudentKey       StudentAccKey     StartDate                          EndDate

    1234                john                         12455666                875755656             2022-10-06                 NULL

    1234                jim                            12455666                875755656             2022-10-06                  NULL

    1234               Sam                           12455666                875755656              2022-10-06                    NULL

    1234               Jack                           12455666                875755656               2022-10-06                  NULL

    9876              Rap                            12455666               567776665                2022-10-06                  NULL

    9876               Swer                          12455666                 567776665                2022-10-06                  NULL

    I am selecting columns from student table. where type = 'HOLL' and Subtype = 'SUXX' , in that case only those 4 records with student id 1234 will be inserted.

    but how i can change or update student id to different 9876 in the select caluse. I tried to use case statement in select but it didnt worked

    like case when ct.type = 'HOLL' and ct.Subtype = 'GEN' then ct.studentid end as studentid

    insert into Student (studentid,

    StudentName,

    StudentKey,

    StudentAccKey,

    StartDate,

    EndDate)

    SELECT studentid,

    StudentName,

    StudentKey,

    StudentAccKey,

    StartDate,

    EndDate

    FROM Student std

    join casetype ct on std.studentid = ct.studentid

    where ct.type = 'HOLL' and ct.Subtype = 'SUXX' and std.StudentKey = 12455666

     

     

  • This is as clear as mud.  You've been around long enough to know that you should post sample data and expected results using (temp) table creates and inserts.

    Also, what is the logic for substituting 9876 for 1234?

  • If this is a one off, then instead of the studentid in the SELECT, then put the scalar value instead.

    As Drew noted, however, make your question easier for people to answer with code (formatted).

  • You have 1 common StudentAccKey with 1 common StudentKey and 1 common StartDate.

    And yet there are two StudentID's and six different StudentName's.

    The code that you're using to get the data has a massive problem and you need to fix that before doing anything else.

    9876 5777 1224567 8876535 1298791 2020-1-20 NULL HOLL GEN

    Here is sample Data.

    For mockup Data, We are trying to insert same set of records with ID 5799 (total 5 records) into same table , but i dont want all 5 records with same ID 5799.

    it shoudl be different caseid 9876. for those first 5 records. When ever student detail records gets created on UI it creates with an ID and associated to Type and SUb type.

  • Didn't Steve answer your question? Seemed pretty clear to me. you just overwrite the ID = 1234 with another value.

    insert into Student (studentid,

    StudentName,

    StudentKey,

    StudentAccKey,

    StartDate,

    EndDate)

    SELECT 9786,

    StudentName,

    StudentKey,

    StudentAccKey,

    StartDate,

    EndDate

    FROM Student std

    join casetype ct on std.studentid = ct.studentid

    where ct.type = 'HOLL' and ct.Subtype = 'SUXX' and std.StudentKey = 12455666
  • Yes he answered, i got it. But the question is we cannot hardcode 9786 in select. because there are tons of records with different student keys. i Just took sample student key. We have to insert the records for each student key based on type and sub type. but in select we have to use id as with type HOLL and Subtype GEN. for each student key.

     

  • You haven't explained how you use the other keys. What you need to do is help develop an algorithm.  Explain for 1234 how you derive this? Or for 9786, how do you use other values to get this.

    What do you mean by "based on"? Be specific, because it is not clear.
