Create view from multiple days tables

Hi,
I'm having existing oracle db with daily stat data, tables strangely named data_mon, data_tue, data_wed.. For my batch processing I plan to use view with multiple day data, let say for last 5 days.
Not sure how better implement my sql statement, with those _mon suffixes to make it more or less dynamic.
I also never create View from multiple tables, so probably I can do something that will add fresh daily data and delete 5 days old data?
Will appreciate you comments on details and whole concept. I have prev sql server experience.
Thanks

TChange the data model so you don't have 1 table for a day.
You just have a DATA table, and a column to denote the day of applicability.
Then you don't need a view, don't need anything dynamic, don't need to smash your head against a wall for a simple query ... etc.

  • Creat View from Multiple tables , Multiple Select

    Hello  Everyone ,
    I have a question and am not sure if this the correct forum to post it .
    I have two table studentTable and CourseTable which is each student  take more than one course . 1:M
    for example Student1 take 2 courses (C1 ,  C2).
    Student2 take 3 courses (C1,C2, C3).
    I need to create a table/View that contain student information plus all the courses and the score for each  course in one row.
    for example
    Row1= Student1_Id ,C1_code ,C1_name  ,C1_Score ,C2_code,C2_name ,C2_Score
    Row2=
    Student2_Id,C1_code,  C1_name,C1_Score,C2_code ,C2_name ,C2_Score ,  C3_code,C3_name,C3_Score
    and since Student 1 just took two courses  , I  should enter NULL in 'Course 3 fields'
    My Struggle is in the insert  statement
    I tried the following but it show an error
    Insert Into  Newtable
    ( St_ID, C1_code,c1_name, C1_Score ,C2_code  ,C2_name,C2_score,C3_code ,C3_name,C3_score)
    Select
    (Select St_ID from  StudentTable)
    (Select C_code,c_name,c_Score
    from  Coursetable,SudentTable
    where course.Stid =Studet.stid)
    (Select  C_code,c_name,c_Score
    from course ,student
    where course.Stid =Studet.stid  ),
    (Select C_code,c_name,c_Score
    from course ,student
    where  course.Stid =Studet.stid );
    I'm fully aware that the New table will break  the rules of normalization ,but I need it in this way for specifc purpose.
    I tried  also the PIVOT BY functionality but no luck with it .
    FYI , I'm not  expert in using SQL Syntax , I just know the basic.
    I will be great full for  any helpfull suggestions to try ,
    thank you very  much.

    First Table is Member table which Represent
    Students Information
    .The fields in this table are

    ,module_k(Foreign key to connect to Module table), module_confirmed_grade_src, credit_or_result
    Third Table is
    AllModuleInfo which is include
    general information for each course .The fields in this table are
    Module_k (Primary key), module_name ,module_code, Module_credit, Module stage.
    The New table
    that I will create has the following fields
    member_sk (PrimaryKey), full_or_part_time, gender, age_at_entry, age_band_at_entry, disability, ethnicity,
    widening_participation_level, nationality 
    " This will be retrieved from Member table"
    Also will include
    Module 1_name ,module1_code, Module1_credit, Module1_ stage, member1_stage_sk
    , module1_confirmed_grade_src, credit1_or_result
    Module 2_name ,module2_code, Module2_credit, Module2_ stage, member2_stage_sk
    , module2_confirmed_grade_src, credit2_or_result
    I will repeat this fields 14 times which is equal to Maximum courses number 
    that any of the students took.

  • How to CREATE VIEW to merge two tables each of which has CLOB-typed column

    I failed in creating a view to merge two tables that have CLOB-type column each.
    The details are:
    Database: Oracle 9i (9.2.0)
    Two tables "test" and "test_bak", each of which has the following structure:
    ID Number(10, 0)
    DUMMY VARCHAR2(20)
    DUMMYCLOB CLOB
    The following operation fails:
    create view dummyview (id, dummy, dummyclob) as
    select id, dummy, dummyclob from test
    union
    select id, dummy, dummyclob from test_bak;
    I was announced:
    select test.id, test.dummy, test.dummyclob
    ERROR in line 2:
    ORA-00932: inconsistent data type: required - , but CLOB presented.
    But if creating views from only ONE table with CLOB-type columns, or from two tables WITHOUT CLOB-typed columns, the creation will succeed. The following 1) and 2) will succeed, both:
    1) one table, with CLOB-typed column
    create view dummyview (id, dummy, dummyclob) as
    select id, dummy, dummyclob from test;
    2) two tables, without CLOB-typed columns
    create view dummyview (id, dummy) as
    select id, dummy from test
    union
    select id, dummy from test_bak;
    I want to merge the two tables all, with complete columns, how to write the CREATE VIEW SQL statement?
    many thanks in advance

    Dong Wenyu,
    No.
    But you could do this:
    SELECT source.*, nvl (tab1.clob_column, tab2.clob_column)
    FROM your_table1 tab1, your_table2 tab2, (
    SELECT primary_key, ...
    FROM your_table1
    UNION
    SELECT primary_key, ...
    FROM your_table2
    ) source
    WHERE source.primary_key = tab1.id (+)
    AND source.primary_key = tab2.id (+)
    In other words, do the set operation (UNION (ALL)/INTERSECT/MINUS) on just the PK columns before pulling in the LOB columns.

  • View from multiple tables

    Hi,
    I would like to create a view from 4 different tables. How do I do it?.
    Say for example, I need user_id from table A which has the trans_id in table B and C. and I need to get a admin_id from table D and show these related fields in one single row . I'm trying to create a view to achieve this.
    Pls help.
    Thanks,
    Ananth

    Are you asking how to write the SQL, or just how to define the view (which I guess is pretty much the same thing)?

  • How to setup Compressor to create video from multiple sequences within FCP?

    I am wondering how I can set compressor up to create videos from multiple sequences within FCP. When I click file -> export - > compressor for a sequence and go into the program, it doesn't allow me to go back into FCP. I just get a spinning beach ball. Is there no way to set it up so I can prep a bunch of fcp sequences within compressor and then click submit and walk away? I have over 100 sequences that need to be exported so it would be a little difficult to do this one at a time. Thanks.

    Batch processing
    *Step one. Make sure everything in every sequence is rendered.*
    *Step two. Make a folder somewhere and name it something relevant.*
    *Step three. In FCP select all you sequences that you want to compress and right click (option), choose Batch Export from the contextual menu.*
    *Step three point one. In the batch export window click on settings and choose the folder you made in step two for the destination. Make sure Make Self-Contained is not check and include Audio and Video.*
    *Step four. Click export in the batch window.*
    Once that is done you can close FCP.
    Now in Compressor
    *Step five. Make a setting that will give you the output that you want (mpeg2, AC3, h.264, whatever). Make a destination for where you want to save the output.*
    *Step six. Make a droplet from the settings you made in step five.*
    You can quit Compressor now.
    *Step seven. Take the files that you batch exported from FCP in step three and four and drop them on the droplet you made in step six.*

  • Query regarding the data type for fetcing records from multiple ODS tables

    hey guys;
    i have a query regarding the data type for fetcing records from multiple ODS tables.
    if i have 2 table with a same column name then in the datatype under parent row node i cant add 2 nodes with the same name.
    can any one help with some suggestion.

    Hi Mudit,
    One option would be to go as mentioned by Padamja , prefxing the table name to the column name or another would be to use the AS keyoword in your SQL statement.
    AS is used to rename the column name when data is being selected from your DB.
    So, the query  Select ename as empname from emptable will return the data with column name as empname.

  • Create XML (using DTD) from multiple relation tables

    Hello and thank you in advanced.
    I'm trying to create an XML document, based on a specific DTD, by selecting information from multiple tables in the database.
    Is there a tool (in XDK maybe?) that will allow me to map my relational tables to a specific DTD?
    I could build the XML manually, but I was hoping that Oracle has already solved this problem with an automated tool.
    Thanks again,
    Sean Cloutier

    Is that the same thing as me writing an XSQL document which contains all of my queries (or views).
    In other words, do I have to map everything by hand or is there a tool to do that for me?
    thanks again,

  • Crate view from multiple tables in mysql

    does anybody know what the correct syntax is?
    I need to do the following:
    create view myView as select * from tOne, tTwo, tThree;this does not work in mysql. How this can be done?
    thanks

    You need to be using a version of MySQl that supports views, 5.0 or greater. This SQL will tell you which version you are using:
    SELECT version();The tables also need to exist prior to the creation of the view.
    Otherwise, that syntax should work...

    Having done this, I must reiterate what others have already said. This is a spectacularly bad idea. Rather than creating a view, I would change it to generate a CREATE TABLE statement to dump the data into proper tables.

    I'm missing something simple.
    I'm trying to create a view, from a Database Link.

    FROM schema.tablename@dblink a;
    When I run this in the SQL Commands window.

    What am I missing? Any help is appreciated...

    <i>CREATE VIEW vw_name
    AS SELECT a.*
    FROM [email protected] a;
    </i>
    <br>
    1) User (schema) which is creating view must have proper db_link to source database. For that try this for testing purpose:
    select 1 from [email protected]<br>
    If this fail then db_link is not ok! This step is absolute must to go any further step to!!!
    <br>
    2) when db_link is set, then your view should be named as:
    CREATE VIEW vw_name
    AS SELECT *
    FROM <b>schema_name</b>.[email protected];<br>
    please pay attention to "schema_name", because from remote side every table is in some schema so it really need declaration of owner schema.
    <br>
    Hope this helps...
