SQL help

Hi guys,.

Please can you help with this query

CREATE TABLE test (id NUMBER, code NUMBER, prefer VARCHAR2(1), status VARCHAR2(1), email VARCHAR2(50));
          
          INSERT INTO test VALUES (123, 2,'N','A','test');
          INSERT INTO test VALUES (123, 2,'Y','A','test2');
          
        

I have this request

        
          SELECT *
            FROM test
           WHERE id = 123
             AND (code = 2 AND prefer = 'Y' AND status = 'A') OR (code = 2 AND status = 'A');          

This returns two records but I want only 1 sheet to be returned because it meets the first condition: code = 2 AND you prefer = 'Y' AND status = 'A '. If it did not meet this condition, I want to check the second codition: code = 2 AND status = 'A '. How should I write this query.

Thank you.


Thankc.

= 2 AND you prefer = 'Y' AND status = 'A' ode c = 2 AND you prefer = 'Y' AND status = 'A' How

Try this

Select * from

(

SELECT test.*

-case when code = 2 AND you prefer = 'Y' AND status = 'A' then 1

When the code = 2 AND status = 'A' then 2

otherwise 0 end chk

OF the test

ID WHERE = 123

order by chk

) where rownum = 1

  • SQL Help: Add flag for several tables

    Hello

    I have an existing SQL as follows:

    Select the storeId field,

    (select case when count (1) > 0 0 otherwise then 1 end)

    of tb_bbb

    where tb_bbb.id = tb_base.baseId) AS conInd

    Hello

    Here is another way, which may be more effective because it uses EXISTS (which can quit smoking as soon as it finds a match) instead of COUNT (who continues to go, so he can tell you if there are 999 or 1000 matches, even if you don't care to).

    SELECT storeid

    CASE

    WHEN THERE IS)

    SELECT 1

    OF tb_bbb

    WHERE bbb_id = m.baseid

    ) 1 THEN

    WHEN THERE IS)

    SELECT 1

    WHERE ccc_id = m.baseid

    ) 1 THEN

    0 OTHERWISE

    Use the ROW_NUMBER analytic function to generate the new sernos, like this:

    MERGE INTO dst test1

    WITH THE HELP OF)

    SELECT ROWID AS r_id

    ROW_NUMBER () OVER (PARTITION BY storeid

    ORDER BY NULL

    ) AS serno

    OF test1

    )               src

    ON (summer time. ROWID = src.r_id)

    WHEN MATCHED THEN UPDATE

    SET dst.serno = src.serno

    ;

    Really, your table must have a primary key.  Because it's not working, I had to ROWID allows you to uniquely identify the lines.

    I need help on getting the sql code.
    Here is how the example data are arranged in my data table called for example.

    favorite colors of name age
    John doe 15 Red: Blue: Green

    Notice how the data in the column "favorite colors", defined the values selected from a list of several.
    I need the sql code so that it can display like this.

    favorite colors of name age
    John doe 15 Red
    John doe 15 blue
    John doe 15 green

    Thank you

    Hi bigmac704,

    There may be other ways to do it, but one way is to use apex_util.string_to_table with a function in the pipeline:

    (1) create a type to define the line of your favorite color of the person:

    CREATE OR REPLACE TYPE  PERSON_COLOR as object (name varchar2(30), age number(3, 0), fav_color varchar2(10));

    (2) create a type to define a "picture" of your person-favorite color lines:

    CREATE OR REPLACE TYPE  PERSON_COLOR_TBL AS TABLE OF person_color

    (3) create the following function in the pipeline:

    CREATE OR REPLACE FUNCTION get_person_colors RETURN person_color_tbl
PIPELINED IS
  out_rec    person_color := person_color(null, null, null);
  l_vc_arr2  APEX_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
  FOR r IN (SELECT * FROM person_colors) LOOP
    out_rec.name := r.name;
    out_rec.age := r.age;
    l_vc_arr2 := APEX_UTIL.STRING_TO_TABLE(r.fav_colors);
    // for each color, pipe a row
    FOR i IN 1..l_vc_arr2.count LOOP
      out_rec.fav_color := l_vc_arr2(i);
      pipe row(out_rec);
    END LOOP;
  END LOOP;
  RETURN;
END;

    Now you can use this function in the pipeline, just as you would use a table:

    SELECT * FROM TABLE(get_person_colors);
NAME AGE FAV_COLOR
john doe 15 red
john doe 15 blue
john doe 15 green 

SELECT * FROM TABLE(get_person_colors) WHERE name = 'john doe';
NAME AGE FAV_COLOR
john doe 15 red
john doe 15 blue
john doe 15 green 

SELECT * FROM TABLE(get_person_colors) WHERE name = 'jim smith';
no data found

    Hope this helps,
    John

    Posted before you see the following

    the sequence # must be continuous, must avoid any shortfall or gaps with the numbering.

    the foregoing must be the only user of its own sequence somehow and maybe...
    Search for "sequence free gap"... http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:4343369880986

  • RDB. Oracle with SQL help

    Hi all the gurus.

    I m NOT a guru :-(

    It's my problem.
    I have 2 tables with same columns
    sales_calculation_text and tmp_calculation_text.
    Columns of the SALES_CALCULATION_TEXT table: (and tmp...)
    Column name Data Type Domain
    ----------- --------- ------
    STOCK_ID TANK (2)
    DEAL_NO CHAR (10)
    CALC_VERSION_NO SMALLINT
    TEXT_ROW_TYPE TANK (25)
    TEXT_ROW_NO SMALLINT
    TEXT_ROW TANK (80)


    The SALES table contains about 800000 lines and is used by the application.

    Every night the TMP table is fallen, recreated and populated by some infiles. After the table TMP contains the population every night
    some exactly identical rows in the SALES table, a few new lines and a few lines with update TEXT_ROW.
    The infiles contains:
    new DEAL_NO of information
    old DEAL_NO with TEXT_ROW update on the existing test_rows (won´t be moved to SALES-table with todays SQL...)

    After that TMP table is re-created/filled the following sql code moves the data:

    INSERT INTO sales_calculation_text
    SELECT * FROM t tmp_calculation_text WHERE
    NOT EXIST
    (SELECT * FROM sales_calculation_text where)
    a.stock_id = t.stock_id and
    a.deal_no = t.deal_no and
    a.calc_version_no = t.calc_version_no and
    a.text_row_type = t.text_row_type and
    a.text_row_no = t.text_row_no);
    COMMIT;

    This has been very good since the beginning of the application a few years ago, but recentlly that the infiles contains updated TEXT_ROW that will not be updated
    by the sql...

    I don't have the skills to write SQL - someone please HELP me...

    BR

    Bjornr

    After INSERTING run this

    UPDATE sales_calculation_text a
SET text_row = (select text_row FROM tmp_calculation_text t WHERE
a.stock_id=t.stock_id and
a.deal_no=t.deal_no and
a.calc_version_no=t.calc_version_no and
a.text_row_type=t.text_row_type and
a.text_row_no=t.text_row_no)
WHERE 1=(SELECT count(0) FROM tmp_calculation_text t  WHERE
a.stock_id=t.stock_id and
a.deal_no=t.deal_no and
a.calc_version_no=t.calc_version_no and
a.text_row_type=t.text_row_type and
a.text_row_no=t.text_row_no);
COMMIT;

  • SQL Help: selection of tickets without open tasks

    Hi gurus,

    I'm new to SQL. I need your help for a script where I pick up tickets without open tasks.
    Say, here is the table of tasks

    Table: task

    ------------------------------
    | TicketID | TaskID. TaskStatus.
    ------------------------------
    | 1. 1. O |
    | 1. 2. O |
    | 1. 3. O |
    | 2. 4. C |
    | 2. 5. C |
    | 3. 6. C |
    | 3. 7. O |
    ------------------------------
    The query should return the ticketid (s) with all its taskstatus = 'C '.

    Any help would be much appreciated.

    Thank you

    Hello

    Frank,

    Your query will exclude other State of the task?

    Try it and see!

    If, in your real problem, the relevant information are spread over three tables, then join them.
    If there is a condition of additional, based on reason, then add that. The WHERE clause is the most logical place.
    If you are interested in taskstatus in 'C' or 'F', then test for one or the other.

    If the GROUP OF... HAVING solution is:

    SELECT       ti.ticketid
FROM       ticket     ti
JOIN       task          ta     ON ti.ticketid          = ta.ticketid
JOIN       taskstatus     st     ON ta.taskstatusid     = st.taskstatusid
WHERE       ti.reason     = 'C'
GROUP BY  ticketid
HAVING       COUNT (*)     = COUNT     ( CASE
                         WHEN  st.taskstatus IN ('C', 'F') THEN 1
                      END
                    );

  • Logical year SQL help...

    Hi, can anyone suggest a better way to please...
    I'm looking to calculate the number of policies here and I want to group counties datewise/yearwise as below:

    (1) County policies added during the month of the date of entry into
    (2) policies County added since (1 month to 1 year)
    (3) policies County added in the second year (i.e. between 1 year and 2nd year)
    (4) County of policies are complemented by year 2 (i.e. > 2 years)

    Below is the example sql with that I came:

    (1) select count (plcy_id)
    from table_1 b
    where
    b.PLCY_EFDT < = b.ORIGINAL_PLCY_EFDT + 30


    (2) select count (plcy_id)
    from table_1 b
    where
    b.PLCY_EFDT (b.ORIGINAL_PLCY_EFDT + 30) AND (b.ORIGINAL_PLCY_EFDT + 360)

    (3) select count (plcy_id)
    from table_1 b
    where
    b.PLCY_EFDT (b.ORIGINAL_PLCY_EFDT + 360) AND (b.ORIGINAL_PLCY_EFDT + 720)


    Count (plcy_id) select 4)
    from table_1 b
    where
    b.PLCY_EFDT > = b.ORIGINAL_PLCY_EFDT + 720


    Please let me know if there is any way to rewrite the query... Thanks for the help.

    better to use the add_month function
