Select the data if a value has a certain value?

Hello, I'm trying to do...


In pseucode, it looks like to...

If this field has a value, then select a, b, c,... of table
another "don't do anything".

How can I do that, I tried...

Select decode (LKP2. EXCLUDED_BOOK_CD, not null,
(select 1 double),
('NOT NULL', 'ALL')
OF LKP2 fcl_chunk_pid_correspondence
WHERE LKP2. CHUNK_ID =: p_chunk_id
AND LKP2. GCDS_ENTITY = "TRANSACTION".
AND LKP2. EXCLUDED_BOOK_CD IS NOT NULL
AND LKP2. UBR = "OTHER";

But this does not work if there is not any row for where.

Thanks in advance!

write a case statement as

Select the case while sal is not null, then end of sal from emp;

    I want to select the data KEY for table TB_ENCRYPT column and update in the column of tables for the respective key user password

    TB_ENCRYPT table contains only a single key value. Comparing this key, I want to update the old value of the key to the new value.

    For encryption and decryption I followed the java class method.no is worried about that.

    the location being c1;

    commit;

    Help, please

    You can use the MERGE statement.

    merge into users
using tb_encrypt
   on (id = userid)
  when matched then
      update set password = PCK_ENC.ENCRYPT(password,key);

    And why you encrypt your password. This isn't a good idea. Just password hash.

  • outer join while selecting the date max

    Hello
    Oracle 11g R2.

    I want to build a query that joins outside between 2 related tables, but selects only the date max if more than 1 record returned for a given customer. Here are the tables I and some records.

    create table customer (NumCli number, name varchar2 (100))
    create table orders (ordnum number, NumCli number, date orddate)

    insert into customers values (1, 'ABC')

    insert into orders values (1, 1, sysdate)
    insert into orders values (2, 1, sysdate + 1)
    insert into orders values (3, 2, sysdate + 2)

    I created the following query, but it returns the two dates for NumCli = 1. I want to display the name of the client no matter if he has a prescription. But if there is more order, I want display the folder with the date max.

    Select a.custnum, b.SID, b.orddate
    client a, b of orders

    Thanks for the comments and certainly once I comment out the following line.
    - AND t4.bookdate between 20110101 and 20111120

    then the values are adapting, but at the same time why do we need to comment the date range condition as case is just a filter and not the condition.

    filter should be-

    -------- ----------------
    Smith 11/02/2010
    John 01/10/2009

    Smith 03/10/2010


    I want to select all names including load_date exist in February AND March.

    Expected results: -.

    Smith

    I can use the intersect operator to get all the names that were given in February AND March by using the following query.

    Select the name of the table where to_char ("load_date, ' FMMonth YYYY") = "February 2010"»
    intersect
    Select the name of the table where to_char ("load_date, ' FMMonth YYYY") = "March 2010"»


    Y at - it an easier way to retrieve the same data that is similar to the use group by, having cluase etc?

    Thanks in advance.

    Hello

    You can do it in one pass through the table with GROUP BY and HAVING:

    SELECT       name
FROM       table_x
WHERE       load_date     >= DATE '2010-02-01'     -- First date inside target range
AND       load_date     <  DATE '2010-04-01'     -- First date OUTSIDE target range
GROUP BY  name     -- not TRUNC (load_date, 'MONTH')
HAVING       COUNT (DISTINCT (TRUNC (load_date, 'MONTH')))     = 2
;

    Try to keep the columns indexed by themselves in comparisons; in this way, you can use indexes.
    For example, if there is an index on load_date, then the above query could use, as load_date is only on one side of the > = or<>
    A similar State

    where   to_char (load_date, 'FMMonth YYYY') = 'February 2010'

    cannot use an index on load_date, because we do not compare load_date - we compare the results of TO_CHAR (load_date,...).

  • SELECT the data inserted into a global temporary Table in a stored proc

    A stored procedure is run from Oracle SQL Developer to insert data into a global temporary table. A SQL (in Oracle SQL Developer) worksheet is open to run a SELECT query to retrieve the data from the temporary table overall which was populated in the stored procedure. No row is returned. I guess it's because the stored procedure and the SELECT statement executed in different sessions.

    Is it possible to run the stored procedure in Oracle SQL Developer and then execute a select statement on the temporary table overall which was filled in the stored procedure by using the same connection so that the data can be extracted?

    I use version 1.5.1 build HAND-5440 of Oracle SQL Developer.

    In a worksheet, do something like

    Start
    insert_proc;
    end;

    Select * from my_temp_table;

    Place the cursor on each statement in turn and Press f9 (where it all began... the end is a single statement.

    Maybe you can share what, exactly, you enter in a cell.  A screenshot is also useful.

    Here's a way to do what I think you want:

    Enter amounts in cells B1, B2 and B3

    Select cell B6, and type (or copy and paste it here) the formula:

    =B2*B3*B1/365.25/100

    Ah!

    If your condition is much easier

    "since just last month" for me what it wanted to say from the 1st to the last day of the previous month.

    Yes, you got it right with "timestampadd (SQL_TSI_MONTH,-1, current_date)" be aware that it does not mean "last 30 days".

    When you're in March he will be only 28 or 29 days (if 29 Feb there exists this year) and the same months have 31 days.

  • Select the data from collections plsql

    Hi all

    I'm not a developer but working as a DBA, so not very familiar with pl/sql, always crossed with documentation and could lead to a solution of my problem. I need advice from expert here.

    Problem: I am writing in a kind of special program plsql for surveillance of certain lots, I know that we have much option to do the same db/grid control including... etc but for some
    the reason I have to do this, use only plsql.

    Requirement: my requirement is to select data in the plsql table and then have the opportunity to ask questions again and again. I prefer not to go to table, rather than directly from plsql...

    I wrote below the code for the sample, bulk data in collection type collection and can print using the loop.

    Declare
    TS type is table v$ session % rowtype index by pls_integer;
    tsess ts.
    Start
    Select * bulk collect into tsess from v$ session;
    I'm looping 1.tsess.count
    dbms_output.put_line (tsess (i) .terminal);
    end loop;
    end;
    /

    But is it possible same collection (tsess in the example above) can be queried using a select as ' select * from table (Tsess) "I searched the net and found this can be done using create type at the database level.» But my problem is that I can't create any object in the database as being it's a production one.

    I was looking as if is it possible even can be accomplished... as cast / multiset... However, I could not get it through.

    your help would be appreciated!

    Kind regards

    I don't think you should use the tables here, only SQL, take a look at the factors of subquery and will indicate if it is not enough...

    Published by: BrendanP on February 12, 2012 03:07 for an example:

    I understand you want to "Refresh" of data that you already have the database purely to be able to use the SQL such as ORDER BY in multiple ways. Here's how you can do it in the original SQL for a particular example, where you query v$ sql time control processor and disk reads separately (I tested it but the result won't be good look here, so omitting it):

    WITH v AS (
SELECT
    Substr (sql_text,1,500)             sql_text,
    cpu_time/1000000                    cpu_seconds,
    disk_reads,
    buffer_gets,
    executions,
    CASE WHEN rows_processed != 0 THEN Round( buffer_gets / Nvl (Replace (rows_processed, 0, 1) ,1)) END Buffer_gets_rows_proc,
    Round (buffer_gets / Nvl (Replace (executions, 0, 1), 1)) Buffer_gets_executions,
    elapsed_time / 1000000              elapsed_second,
    module
FROM v$sql s)
SELECT
    'CPU'                order_by,
    cpu_seconds          order_val,
    sql_text,
    cpu_seconds,
    disk_reads,
    buffer_gets,
    executions,
    buffer_gets_rows_proc,
    buffer_gets_executions,
    elapsed_second,
    module
FROM v
 UNION
SELECT
    'Disk reads',
    disk_reads,
    sql_text,
    cpu_seconds,
    disk_reads,
    buffer_gets,
    executions,
    buffer_gets_rows_proc,
    buffer_gets_executions,
    elapsed_second,
    module
FROM v
ORDER BY order_by, order_val DESC

  • Select the data on the different data source

    Hello

    There is a Web Application of merger with a Module of the Application that is based on the "database server 1".

    For the calculation of the values of database 1, I need to get data (Table DB) '2 database server.

    How to get values (Table) database 2 in the same project?

    (I must have a second Module of Application maybee?)

    Thank you for advice.

    I suggest to have several app module with in your template project. Suppose appmod1 for "Database Server 1" and appmod2 for "database 2" server.
    I did the same thing in my application and it works very well.

  • Everytime I turn on my laptop, I get a warning that the Data Execution Prevention System has stopped working. Any ideas how to fix this, please?

    Running Windows Vista family - that's all as far as I know!

    Hi Norfolk broad,

    Remember to make changes?

    Method 1:  Put the computer to boot and then check if the problem persists

    Follow step 1 in the link below,

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

    Continue with the remaining steps to pin-point on the third party service.
    After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

    Important: n ' forget not to put the computer to a normal startup follow step 7 in the link.


    Method 2:     if a Protection of resources Windows (WRP) file is missing or is damaged, Windows may not behave as expected. Auditor of file system (CFS) scan to fix all of the corrupted system files. To do this, follow the steps mentioned in the link below:

    How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

    http://support.Microsoft.com/kb/929833
