How to display the results of the database from several tables in descending order?

I have a key word to search for images on my website that allows visitors to search for specific things. My db msysql has 15 tables and for the search function I use a UNION ALL operation to join them any visitor can find all tables at the same time. The problem is that all the results are in ascending order. How can I get the results in descending order.

SELECT *.

FROM table1

Keyword WHERE AS id LIKE %s or %s

UNION ALL

SELECT *.

FROM table2

Keyword WHERE AS id LIKE %s or %s

UNION ALL

SELECT *.

TABLE 3

Keyword WHERE AS id LIKE %s or %s

PS

I tried this and it doesn't work:

SELECT * FROM table1 WHERE AS %s or id AS %s ORDER BY id DESC keyword

and I know that this is not conventional to use SELECT * with so many tables, but believe me, I have my reasons. I'm not trying to do is to wrap the whole UNION within an external SELECTION

Once more, the order by clause can only appear at the end of the last select statement in a UNION query. You have it on all select statements.

  • * How to display the group from the main query for the first time in the report?

    Hello

    I have developed a group of master / detail in a report
    The master has its extensible framework and the detail of one another framework extensible and put to another page in the page layout.
    The problem is that the master one appears (the same record) in the pages in time equal the number of records in detail that is specific for this master record!
    Example:
    If the master record got three Details then database will show three times (three pages) and then running page number 4 will display the three detail records.

    How to make the master data in shown only for once (page number 1 only) and then display the details three records to the next page (page number2) at run time?

    Hello

    the question is, what you've done for this. By default the primary record is displayed only once. Could it be, that the master-fields are inside the extendable frame for more details?

  • How export/import the database from the Tools menu in sql developer.

    Hello

    I need to export the database to a server and import it on another server db using the export function of database under the Tools menu in SQL developer. How to import it? This is for Oracle database 10g.

    Thank you

    Hello

    You can do it, but I do not recommend because sqldeveloper could eat all the memory of the system to analyze the script. Now the question is do you have also opted for storage option when you export, if yes make sure that similar tablespace exists or available in env b. Also if you want to use the generated sqldeveloper file you can run this file from sqlplus session

    sqlplus newuser/password
    sqlplus > @myexport.sql

    But my advice or suggestion or recommendation to be, you should consider using export/import or datapump but the decision is yours. Hope this helps

  • How to display the records from a query in the non-base data field

    Hello

    I have a problem:
    I have a query with a lot of tables and column 6 (select a, b, c, d, e, f x, y, z, t, s, g where the conditions) and I use 3 parameters.
    I create 3 settings: datai,: dataf and: partner and a button with a trigger when the button is pressed.
    Then a create a block manually with six field non-database a1, b1, c1, d1, e1, f1.
    Now, I want to display all the records in my query in a1, b1, c1, d1, e1, f1 where a1 = a, b1 = b, etc. and all the records (if I have 20 record, it will display 20 records in the non-base data field) when I press the button.

    How I did it:

    start the open cursor
    loop
    Fetch cursor in: a1,: b1,: c1: d1: e1,: f1;

    Creating a view and the query in a database block are a great solution.

    To use the block non-base of data:
    You are missing the most important Next_Record; command.

     Begin
    
Go_block('X'); -- block X is the non-database block
    
Clear_Block(No_Validate);
    
open cursor X1;
    
loop
    
If :System.Record_status != 'NEW' then
    
Next_Record;
    
End if;
    
fetch X1 into :a1,:b1,:c1,:d1,:e1,:f1;
    
Exit when X1%NOTFOUND;
    
end loop;
    
close X1;
    
end;

  • How to display the rows dynamically in Table Adv

    Hi friends,

    I created a custom page its an insert page, user must enter details of employees and save on db, there is a field of messageInput, where the user will enter the number of lines to dsiplay. so that the user will enter details.
    for example: If the user enters 20, so the advanced table should display 20 ranks, if the user enter 30 then advanced table should display 30
    is it possible to script?

    Hello
    It should be possible,
    create a table advanced based on a VO and it should be based on an OA.
    Then get the number of records to be added, once the user click on the button

    run the EO based VO with 1 = 2 condition and then create several lines user number entered in a loop for,.
    and then set the cursor to the first line.

    Your advanced table should have the newly created (empty lines) ready for users to input.

    Once the user enters the values, you can do a commit which will record your data.

    Thank you

    With respect,

  • How to display the list item values both from 2 different tables?

    Hello world.

    I have a problem for the display of the data.

    There are 2 tables in the database.

    Table-1 has lc_value, lc_no, lc_dt, and vendor_code columns.

    Table-2 has vendor_code, $vendor_name & vendor_address.

    I created the form where I display data in list item 30 (tabular presentation - 30 records displayed).

    I need to display all values automatically at the same time in the form just by clicking on "Enter_Query" and "Execute_Query".

    It worked when the form had fields in a table in a single table.

    I created fields in a table for tables; then created the relationship between the tables by using the join (vendor_code).

    But when I run the form, click on "Enter_Query" and "Execute_Query", its does not work.

    Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production.

    How can I do this?

    Help me.

    Thank you.

    Dear Bruno,

    Each provider code is to have a folder, then

    Why keep two tables?

    Why you want to update both the table at the same time?

    Master / detail means,.

    a master record depends on several detail records.

    Please, understand and try to build your form with single table.

    If you have already created 2 tables, then merge these into a single table.

    Or other wise keep table_1 as a database block and to vend_name as a data field (element of database in the palette of the property is set to 'no').

    Then go to the trigger of table_1 block post_query and write the following:

    Select vend_name in: vend_name from vendor_mst where vend_cd =: lc_vend_cd;

    In doing the above, the form will look as you wish but the change on the vend_name not to be saved because that is the point of no database.

    Other than vend_name all fields in table_1 will be recorded.

    Hope this will help.
