Statement UPDATE of SQL TIP about WHERE CLAUSE

(1) Oracle does support SQL UPDATE statement of SUSPICION for WHERE CLAUSE
(2) if so, then please give example.
Thank you.

Hello

Yes, it is possible to use the "tips" in the Update statement

Sake example

Update
/ * + rowid * /.
tableX
Set char_date = '19' | char_date
where nvl (length (char_date), 0) = 6
and rowid between chartorowid ('000927.0000.0008')
and chartorowid('000A3F.) FFFF.0008');

  • Update statement with joins of tables and where Clause

    Hi, I have MS SQL background and I try to execute an update statement in Oracle with joins of tables. However, the syntax below does not work but I think it works for MS SQL.

    Basically, the base table must be attached to a master table trend with monthly snapshots, an account will be only an entry for a given date monthly. Where clause must be limited to accounts within a certain range of interest rates.

    The first approach returns command SQL ORA-00933 not correctly completed, and the second approach returns ORA-01427 row below query returns multiple rows. Can anyone help? Thanks in advance!



    1:

    Update PenaltyAll
    Set a.indicator = month (b.)
    of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
    where a.monthend='01/31/2009' and b.date='12/31/2008' and b.apr < 20

    2:

    Update PenaltyAll
    adjustment indicator =
    (select to_char (b., 'MM')
    of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
    "where to_char (a.monthend,'mm/dd/yyyy ') = 31 January 2009"
    (et to_char(b.date,'mm/dd/yyyy') = December 31, 2008 "
    and b.apr < 20)

  • Question about WHERE Clause

    Hello

    I'm doing a conditional clause where clause displays the lines in a report.

    The desired control is date of two fields (CIC and announcement) must all be virgins or someone not be an 'Admin' (taken from a global variable stored on connection) for her to no display.

    Here's what I have:

    WHERE (DATACOLLECT. ANNOUNCEMENT_OF_DEAL_SIGN IS NOT NULL AND DATACOLLECT. CHANGE_IN_CONTROL IS NOT NULL) OR UPPER(:F19959_USER_ROLE) = "ADMIN".

    During the test of this query, it hides a field with ONE of the two dates being blank and which is not desirable.

    I also tried to write it like this and got an error of analysis for an invalid relational operator:

    WHERE (DATACOLLECT. ANNOUNCEMENT_OF_DEAL_SIGN AND DATACOLLECT. CHANGE_IN_CONTROL IS NOT NULL) OR UPPER(:F19959_USER_ROLE) = "ADMIN".

    Any help would be greatly appreciated. Please let me know if I need to clarify.

    I take what I said back.  Your requirement of "double negative" is odd

    DO NOT SHOW: where (X is null and Y is null)

    translates

    Show: where not (x is null and Y is null)

    WHERE NOT (DATACOLLECT. ANNOUNCEMENT_OF_DEAL_SIGN is null AND DATACOLLECT. CHANGE_IN_CONTROL IS NULL) OR UPPER(:F19959_USER_ROLE) = "ADMIN".

    PS - this is a thing of database.  PL/SQL and SQL would have been a better choice

  • SQL case in where clause

    I have the following table.

    I need to create a query that returns:

    (a) if the table contains 1 and 0 on pass that only values with 1

    (b) otherwise, if the table contains only 1 on collar that only values 1

    (c) otherwise, if the table contains only 0 on pass that only values to 0.

    I tried with the following query, but if the table contains only 0 returns nothing

    {code}

    create table test

    (col1 number);

    Insert in the test

    values (1);

    Insert in the test

    values (1);

    Insert in the test

    values (1);

    Insert in the test

    values (0);

    Insert in the test

    values (0);

    Insert in the test

    values (0);

    commit;

    Select *.

    of the test

    where

    col1 case

    When 1 then 1

    0 otherwise

    end = nvl2 (col1, 1, 0);

    {code}

    Thank you

    Hello

    If you want to find which is the highest value of col1 in the table and view only the lines where col1 has this value.

    Here's a way to do it:

    WITH got_max_col1 AS

    (

    SELECT col1

    MAX (col1) ON (AS max_col1)

    OF the test

    WHERE col1 IN (0, 1) - if necessary

    )

    SELECT col1

    OF got_max_col1

    WHERE col1 = max_col1

    ;

    With the sample data you posted, you do not have the condition: WHERE col1 IN (0, 1)

    If you add lines where col1 can be anything other than 0 or 1, then this condition will ignore them.

  • Case statement in a WHERE clause

    Gurus,

    Im trying to avoid Union of several select statements using a CASE inside a WHERE clause. When the parameter is defined as "What's new" it is advisable to use a code and for "Update Items" another condition.

    Having a problem with the following... I know that BOX in WHEREs instructions are allowed only can not make it work for this one.

    and case  when 'New Items' = 'xxx' --p_item_status 
         then  msi.creation_date = msi.last_update_date
      when 'Updated Items' = 'bbb' --p_item_status  
         then  msi.creation_date != msi.last_update_date
      else 1=1
end; 
    Points for correct and helpful answers!

    Published by: sreese on March 27, 2012 17:51

    Hello

    The great thing about CASE expressions, is that they allow you to use a login IF-THEN-ELSE in the clause SELECT, the ORDER BY clause or anywhere else. The WHERE clause has its own way to IF-THEN-ELSE logic, so even if you can use a CASE expression in a clause WHERRE, it usually does not help anything. You can do somehting like this:

    WHERE     (     :p_item_status        = 'New Items'
     AND     msi.creation_date  = msi.last_update_date
     )
OR     (     :p_item_status        = 'Updated Items'
     AND     msi.creation_date  != msi.last_update_date
     )
OR     (     :p_item_status        NOT IN ( 'New Items'
                           , 'Updated Items'
                           )
     )

    This guess: p_item_status is not NULL.
    If: p_item_status can be NULL, and you want to include all the lines where it is, and then change the last condition to

    OR     ( NVL (:p_item_status, 'OK') NOT IN ( 'New Items'
                             , 'Updated Items'
                             )
     )

    I hope that answers your question.
    If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions), some values of the parameter and the expected results of these data for each value of the parameter.
    Explain, using specific examples, how you get these results from these data.
    Always tell what version of Oracle you are using.

    Oracle sees the empty string ('') as NULL.
    Use IS NULL or IS NOT NULL instead of = or! =

  • NVL selection list does not not on the place where clause in query

    Ok. APEX 4.2...

    Im having problems with my selection lists and NULL values... I see that it has come time and time again...

    I have a tabular presentation, with a query based on a selection list.  The selection list has the ability to '- Show All -'... The value of the selection list is a number, and the display is words...  (for reference the LOV query is: select status, batch from pmt_stat_lookup by 1)

    Initially I had problems with null and invalid numbers like ' display Null = 'Yes' and the problem of null % ', so have used the code in this blog to remove the NULL values... Display Null = & amp; #34; Yes & amp; #34; and the problem of null % | Inside Oracle APEX by Patrick Wolf

    Then in the application of my report, I have a where clause clause that checks the value of the selection list... WHERE batch = nvl(:P11_STATUS_SELECT,STATUS_ID)

    everything works almost fine, and I can choose a status, or I choose - see the All-, but the query will not include the lines where the State is null.

    (I also see that maybe I should be, use the case statement instead of the NVL on where clause, but not sure of the syntax. In addition, NVL was used somewhat in the different reports in the application...)

    For reference, the code of the old blog that I as a process page is:

    BEGIN

    FOR rItem IN

    (SELECT NOM_ELEMENT

    OF APEX_APPLICATION_PAGE_ITEMS

    WHERE APPLICATION_ID = TO_NUMBER(:APP_ID)

    AND PAGE_ID IN (TO_NUMBER(:APP_PAGE_ID), 0)

    AND LOV_DISPLAY_NULL = 'Yes'

    AND LOV_DEFINITION IS NOT NULL

    -change here

    AND LOV_NULL_VALUE = '% null | '%'

    )

    LOOP

    IF V (rItem.ITEM_NAME) = "% null | '%'

    THEN

    Apex_Util.set_session_state (rItem.ITEM_NAME, NULL);

    END IF;

    END LOOP;

    END;

    You typed it wrong or is the same as the variable column name? If they are the same test rename one of them.

    Hello

    Oracle version: 11.1.0.7.0 - 64 bit

    I read the documentation online at joins. The page is avialable here: joins at

    My question is about the join order of evaluation of the conditions in clause and the conditions of those

    are not the join conditions and are placed in the WHERE clause.

    Consider the following pseudocode

    SELECT

    T2.Col1

    Of

    Table1 t1 LEFT OUTER JOIN table2 t2

    WE

    (condition_expression1)

    WHERE

    (condition_expression2)

    Is it correct to say that if there is no column on the status of join (condition_expression1) in condition_expression2, then condition_expression2 is executed before condition_expression1? In other words, oracle always trying to filter based on the WHERE clause individually each table as much as possible before joining them based on the conditions on the article?

    SQL is not a language of the proceedings.  Looking at the code SQL, we could say that the code does, but we cannot say much about how that code it.  In other words, SQL is a language that describes the results you get, not the way to get them.

    The optimizer will do everything what he thinks is faster if it does not change the results.  If any order in which they are applied (in outer joins or CONNECT BY queries, for example), then think of the join is done first, and the value of the WHERE clause is applied to the result of the join.

    Here is a query looks very much like you posted:

    SELECT d.deptno

    e.ename, e.sal

    OF scott.dept d

    LEFT OUTER JOIN scott.emp e ON e.deptno = d.deptno

    WHERE e.sal > = 3000

    ORDER BY d.deptno

    ;

    Output:

    DEPTNO ENAME SAL

    ---------- ---------- ----------

    10 KING 5000

    20 FORD 3000

    20 3000 SCOTT

    The scott.dept table contains deptnos 30 and 40; Why are they not in the result set?  The query behaves as if the outer join is made first (production 15 rows), then the WHERE clause has been applied.  All lines with deptno = 30 had sals down han 3000 and all single line with deptno = 40 was NULL in the sal column, then these lines are excluded (as well as other lines of deptnos 10 and 20), and only 3 lines above are left.

  • Can I use truncated and where clause in the statement even?

    Hello guys,.

    Can I use truncated with where clause in the same statement.


    For ex:

    TRUNCATE TABLE my_table WHERE id < 500;

    If not, that you recommend me to overtemperature to the level of high water line?

    Okay I need an increasing amount of space. However, at the same time I want to recover the spaces empty below HWM. So, I need to use less amount of space I am inserting. Therefore, shouldn't use retractable for this?
    >
    Why waste the effort. Oracle will reuse the space below the HWM when doing inserts. You already said that you insert more lines you delete so all these will be more accustomed to the top.

    The only time where that oracle may not use space is when the space is too small to be useful. It is documented in the doc, I told you
    >
    Understanding recoverable unused space
    Over time, Update, and Delete on objects within a tablespace can create pockets of empty space that individually are not large enough to be reused for the new data.
    >
    Most uses of CONTRACTION I've seen are totally useless. If you follow the doc and run the Advisor of segment it will tell you if there is space that can be retrieved and how much. But, even once, for your use even if case will get you will Oracle while you need to reassign the new extensions, then the HWM will just go still higher.

    If pay you a heavy price in Oracle did a full table scan, update of many blocks from the table, update THE index, impact performance for other users to access the table during the SHRINK and reallocate extensions (maybe even some of the same areas) when you insert more data.

    Do not SHRINK unless you know it's necessary.

    BUT FULL is to get the scores of APR - JUN, INCR becomes partitions for MAY so not both 30 days.

  • How to set SQL that contains 'in' where clause in VO?

    I don't want to set "in" would adopt a kind of programatical in VO as below. I want to use a method declariable to set in the clause using bindings varaible.

    It can be implemented?

        private String getInClauseWithParamNames(List termCodes) {
           //logic to form the in clause with multiple bind variables
           StringBuffer inClause = new StringBuffer(); 
           if(termCodes !=null){
               for (int i = 1; i < termCodes.size() + 1; i++) { 
                   inClause.append(":termC" + (i));
                   if (i < termCodes.size()) { 
                      inClause.append(","); 
                   } 
               }
           }
           return inClause.toString();
    }
        
    public Row[] getYardFixedSlots(List termCodes) {
        if(termCodes != null && !termCodes.isEmpty()){
            String inClause = getInClauseWithParamNames(termCodes);
            //setting the where cluase to use the generated in clause
            this.setWhereClause("YardFixedSlot.TERMINAL_C in (" + inClause + ")");
            ////clearing all existing where clause params if any 
            this.setWhereClauseParams(null);
            if(getVariableManager() !=null){
               this.getVariableManager().clearVariables();
            }
            //setting values for all bind variables one by one in the in clause
            for (int i = 0; i < termCodes.size(); i++) { 
                //defining the named bind variables programatically 
                this.defineNamedWhereClauseParam("termC" + (i + 1), null, null);
                //setting the value for each named bind variable 
                this.setNamedWhereClauseParam("termC" + (i + 1), termCodes.get(i)); 
            }
            this.setRangeSize(-1); 
            //executing the query 
            this.executeQuery(); 
        }
        //returning the rows from query result 
        return this.getAllRowsInRange(); 
    }

    You can only use the link as a parameter to the in clause. You must divide the string inside the binding variable. Sample can be found at decompilation binary ADF: using bind variable for SQL statements with the paragraph

  • using case when statement or decode unfavorable in where clause

    Hi the gems...

    I have a problem in the following query...
    I try to use when case statement in where clause of a select query.


    Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
    CR. Salary salary
    of customer_details cr
    where (case when ' > ' = ' > ' then ' cr.salary > 5000')
    When ' > ' = ' < ' then ' cr.salary < 5000'
    When ' > ' = '=' and then 'cr.salary = 5000'
    Another null
    (end);


    the expression in the when clause of the statement of the case, when comes from HQ and according to the choice I have to make the where clause.
    That is why, for the execution of the query, I put ' > ' in this place.

    If the original query will look like this (for reference):

    Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
    CR. Salary salary
    of customer_details cr
    where (case when variable = ' > ' then ' cr.salary > 5000')
    When the variable = ' < ' then ' cr.salary < 5000'
    When the variable = '=' and then 'cr.salary = 5000'
    Another null
    (end);


    so, in a real case, if the user selects ' > ' then the filter will be ' where cr.salary > 5000.
    If the user selects ' < ' then the filter will be ' where cr.salary < 5000.
    If the user selects '=', then the filter will be 'where cr.salary = 5000 '.

    but I get the error "ORA 00920:invalid relational operator.

    Help, please... Thanks in advance...

    Hello

    select cr.customer_name || ' - ' ||cr.customer_number as cust_name,
       cr.salary                                      as salary
 from customer_details cr
where (    v_variable = 'bigger'
       and cr.salary > 5000
      )
   or (    v_variable = 'less'
      and cr.salary < 5000
       )
   or (    v_variable = 'eq'
        and cr.salary = 5000
       )
