Using a variable in the "LOVE" of a WHERE clause part

How could I go to achieve this?

I SELECT... WHERE AS 123% person_number';

While observing the percent symbol, how I would substitute and explicit value with an implicit reference to a variable, I already assigned a value to?

Thank you very much.

don't know if that's what you need, but you can simply concatenate your variable with '% '.

for example;

SQL> select * from emp1 where job like 'A%';

     EMPNO JOB                  START_DAT        SAL       DEPT
---------- -------------------- --------- ---------- ----------
         3 Author
      4444 AUTHOR               24-MAY-10       5001          3
      3333 ANALYST              24-MAY-09       5004          2

SQL> variable prefix char(1);
SQL> exec :prefix :='A';

SQL> select * from emp1 where job like :prefix||'%';

     EMPNO JOB                  START_DAT        SAL       DEPT
---------- -------------------- --------- ---------- ----------
         3 Author
      4444 AUTHOR               24-MAY-10       5001          3

You cannot use pl/sql variable with values separated by commas in the paragraph directly, you must break into multiple records

Try this too [g 11]

create or replace PROCEDURE emp

IS

emp_id VARCHAR2 (1000);

BEGIN

emp_id: = '1989100351, 1989100352, 1989100354';

FOR rec IN (select employee_id from employee WHERE employe_id IN ())

Select (column_value) .getnumberval)

from xmltable (emp_id)) double.

)

LOOP

dbms_output.put_line (Rec.employee_id);

END LOOP;

END emp;

Can Oracle 10g - I use a variable for the access of the user identifywhat tablesto?
I have the following code in a trigger (PL/Sql block) of a form:

Select fieldname in user1.sometable myvar;

is it possible to use a variable instead of coding hard "user1"? And on the same subject, this variable would also be declared in the world?

Thanks in advance,
Darren
Hello!

User1 is the owner of the table sometable.

If only the User1 runs your form, there is no need to put the tableowner in front of the tablename parameter.

If other users run your form, you must create a public or private (for each user) synonym of this table.
After that, you don't need to use owner.tablename in your sql statement.

But:
You cannot use a variable for the user name without using dynamic sql
as you do if you create a recordgroup.

Use of Variables in the statement of sym.play(1000)

I built a system menu to a main menu with three options and a single submenu animation that should be limited to one of the three different places on the timeline, depending on which is click the main menu button.
For each button in the main menu, I created a click made up of sym.setVariable event ("Subselection","#" ""); in "#" can be set to 1, 2 or 3. When you click on one of the buttons on the main menu and the submenu opens at the end of this sequence, I inserted the following text - sym.play(1000) (subquery);
It is all quite clearly displayed in the snap-in to display annotated below.
It is important for me to master the use of variables and strings concatenated in the instruction of sym.play(1000) so I can create as compact as possible OAM files, so any help is greatly appreciated. My guess is that I am a stupid syntax error, but I am not opposed to picking the brains of others when mine is insufficient for the task at hand.
Thank you very much.
Andy.

Hi Harley,

Image labels are 1,2,3 etc.

sym.setVariable ("Subselection", 0); in the composition of the scene ready

Then in the menu, you can set the variable "Subselection" 1,2,3 and then call sym.play(1000) (sym.getVariable ("do"));

Thank you and best regards,

Using of Variable in the filter expression will not scan.
IN ODI 11.1.1.3.0, I've defined a Variable of type 'Alphanumeric' (SelectionDate), default = January 1, 1970 with the query select: select to_char (SYSDATE, 'DD-MON-YYYY') of double.
I intend to use this variable as a scenario (parameter) variable that receives a value in the form "DD-MON-YYYY', of the execution environment.
I refreshed the variable and the value received June 16, 2011 (current date). So far so good.

Then, I defined an Interface and use the variable in a filter expression:

Filter active: checked

Tab implementation:
SOURCE_VIEW. SELECTION_DATE BETWEEN TO_DATE (' #PROJECT1.) SelectionDate', 'DD-MON-YYYY') AND (TO_DATE (' #PROJECT1.)) SelectionDate', 'DD-MON-YYYY') + 1).

Run on: Source

During the verification of the expression (click the check mark in the application tab) I always get: Expression is not valid for the DBMS. java.sql.SQLDataException: ORA-01858: a non-digit character was found here where was waiting for a digital.

I can't filter to analyze. Thank you for your ideas of what could be wrong.

Jose.
Hi Jose,

You must set this variable in a package and refresh it. Then place your interface with the current filter condition.
Run the package. It should work.

Thank you

Use of variable in the For-Each statement
Hello gurus.

I'm having a problem using a variable, I created in a statement for each. Here is the code I am using
My goal is to create a variable based on the type of Bill. If the invoice is a proof or a reprint, a copy should be printed. If it's a final bill, I need two copies.

<? xdoxslt:set_variable($_XDOCTX,_'x',_0)? >
for each<? If: Print_Additional_Header_Text_ID238 = "PROOF"? > <? xdoxslt:set_variable($_XDOCTX,_'x',_1)? > <? end if? >
<? If: Print_Additional_Header_Text_ID238 = "REPRINT"? > <? xdoxslt:set_variable($_XDOCTX,_'x',_1)? > <? end if? >
<? : otherwise (Print_Additional_Header_Text_ID238)? > <? xdoxslt:set_variable($_XDOCTX,_'x',2)? > <? end if? >
<? xdoxslt:get_variable($_XDOCTX,'x')? > <? for-each@section:xdoxslt:foreach_number($_XDOCTX,1,$x,1)? >

foreach is the loop that I use to repeat sections of the Bill.

When I run with the last impression for each preview, I get an error that says "undefined variable: 'x'"»
But when I remove the last for each good variable, 1 or 2, will show in the invoice.

My question is: How can I use the variable 'x' in <? for-each@section:xdoxslt:foreach_number($_XDOCTX,1,$x,1)? >

TIA
Darius

The use of variables in the Calc scripts and business rules

I'm sure that there have been previous discussions on this topic, but can anyone let me know the benefits of using variables in scripts of Calc and BRs?

Thank you
A

I've never used variable Calc and after reading a guide to the study, which has talked about them, I didn't really understand the benefits.

^ ^ ^ I use variables all the time to make difficult abstract formulas. Here is an example.

/*     Declare variables     */
VAR varSalaryCosts ;
VAR varProdOHLabXXXX ;
VAR varXXXX ;

A whole bunch of code here along with very limited FIX statement and then...

"Salaried Labor"
(
     varSalaryCosts = "Salary Costs"->"No Department"->"No Category"->"Salaried" -
                         "Wage Bonus"->"No Department"->"No Category"->"Salaried" -
                         "YYYY Retention Bonus 40%"->"No Department"->"No Category"->"Salaried" -
                         "YYYY 60% Ret Bonus Accrual"->"No Department"->"No Category"->"Salaried" ;
     varProdOHLabXXXX = "Number of Employees"->"ZZZZDepartments"->"Codes"->"Salaried" +
                         "Number of Employees"->"Blah Departments"->"Codes"->"Salaried" +
                         "Number of Employees"->"Humph Departments"->"Codes"->"Salaried" +
                         "Number of Employees"->"TTTT"->"Codes"->"Salaried" ;
     "Salaried Labor" = varSalaryCosts * ("Number of Employees"->"Salaried" / varProdOHLabXXXX) ;
)

The last formula is how the formula was described to me by the owner of the company. I find it much easier to read something like:

"Salaried Labor" = ("Salary Costs"->"No Department"->"No Category"->"Salaried" -
                         "Wage Bonus"->"No Department"->"No Category"->"Salaried" -
                         "YYYY Retention Bonus 40%"->"No Department"->"No Category"->"Salaried" -
                         "YYYY 60% Ret Bonus Accrual"->"No Department"->"No Category"->"Salaried") *
                         ("Number of Employees"->"Salaried" /
                         ("Number of Employees"->"ZZZZDepartments"->"Codes"->"Salaried" +
                         "Number of Employees"->"Blah Departments"->"Codes"->"Salaried" +
                         "Number of Employees"->"Humph Departments"->"Codes"->"Salaried" +
                         "Number of Employees"->"TTTT"->"Codes"->"Salaried")) ;

I used the TABLE in a calc script really-cool-but-alas-not-invented-by-me do better than planning made the conversion of currency currency conversion in planning. (How's that for a run-on sentence?) It is one of the six blog posts that I'm trying and I will end it soon, I hope. I am now thrash mode. It doesn't have its uses and I'll try to remember to update this thread when I'm done.

Column unresolved when using presentation variable in the filter responses
Hi all

I am using a dashboard command prompt that sets a variable presentation - pres_year. I use the presentation variable in the filter of the application.
In the 'Criteria' tab, in the filter for a request, I put a year column (YEAR) the presentation via the Expr Variable variable and enter the variable name of presentation only. End up with:
YEAR is equal to / is in @{pres_year}

When you use the dashboard, the prompt and ask all work fine. The problem is when I'm in demand for answers and I click on the "View results" button I get the following error:
"NQSError: 27005 unresolved column pres_year'.

Any suggestions?

Thank you.
Set a default value after the presentation variable in your filter. If you put no default value, and then in the responses, the application not of value to the variable of presentation. Click on the filter and add default value. Then it won't work.

How to use text variables and the Image for printing

I work for several months on the product with AS3 Configurator.
I am not competent with AS3.
Now, it seems that perhaps my design is all wrong.
Is there a good way to do this?
I have a main scenario that has video clips showing images of different options for the product.
On the first image, I use buttons to select the choice for option 1 of the Option1_mc.
Can I store the selection in a variable.
I use a button to go to the next choice (screen 10.)
On frame 10, I use buttons to select the choice of option 2 in the Option2_mc.
It is stored in another variable.
There are about 10 options that are selected and stored in variables.
Some are text values and other images taken from video clips Option instances.
I made a Print_mc to use to printjob.
I can't get the values of the variables to display the first image for printing.
Any helpl would be appreciated.

You are welcome.

you will not be able to insert a variable into a textfield. you are going to assign to the text of your TextField property set to one of your points of variables to.

Thus, for example, if you have:

var var1:String = 'this is a test ';

You can use:

TF. Text = var1;

Published by: user10941925 on March 4, 2012 22:31
Hello

CASE expressions return a single value, for example a VARCHAR2. They do refer to code fragments.

You usually don't need (or want) an expression BOX in a WHERE clause, or any other condition. I think that you were trying to do the equivalent of:
```
AND     (     (:KAPCO = 'KAPCO'          AND cla.CLASS_NAME       LIKE '%KAPCO%')     -- Don't you want UPPER on this line?
     OR     (:KAPCO = 'NON_KAPCO'           AND UPPER(cla.CLASS_NAME) NOT LIKE '%KAPCO%')
     OR     (NVL (:KAPCO, 'ALL') = 'ALL'       AND cla.CLASS_NAME IS NOT NULL)
     )
```
If you would care to post some sample data (CREATE TABLE and INSERT statements) and the results desired from this data, I was able to test this.

Using the index function in where clause of Exchange.

Hello friends,

I need your help with a problem.

I have a query that uses two table Say T1 and T2, where C1 is common column with which both are joined.
C1 is the primary key in T1, but no index available in Q2 for the C1. T1C2 is the column that we want to select.
(Note that table may be a Master table)

Now let's see the query:
Select T1C2
From T1, T2
where T2. C1 = T1. C1

Here where the clause may have other conditions and From clause can have other tables as needed.

I want to know that if I have change the query as continuation of leave my query to use the index available of T1. C1.

Select T1C2
from T1, T2
where T1. C1 = T2.C1

Then, the query uses the index available of T1. and I get better performance. Even a small improvement of performance help me much because this type of query is used in a loop where clause (so it will be run several times).

Please advise on this...

Kind regards

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
       )
```

Best place to initialize the View object query where clause or params
Where is the best place to initialize the View object 'where' clause before the page is initially rendered? Or how should it be done?
Specifically, I can't set these values in the entity or view objects because I need information from the user or information Session
the user has entered before you navigate to the page. I want to prepare the View object so that the results of the query appears something reasonable
the first time before using chooses search.

Note: The view object must exist and I need to access managed beans to define the query.

Is there an event hook (java code) that can be called before the page is rendered?
Also, there are hooks that can be called when the user navigates to another tab or page?

How to filter the result with a where clause clause?

Hello

I have a nice sql query. I would like to include a where clause with a joker clause.

If the user selects for example a "AGENT_ID", then where clause would include the AGENT_ID, otherwise, every thing would appear.

SELECT 
   "FICHE"."FICHE_ID" "FICHE_ID", 
   "FICHE"."AGENT_ID" "AGENT_ID", 
   "FICHE"."EQUIPE_ID" "EQUIPE_ID", 
   "FICHE"."DATE_ACTIVITE" "DATE_ACTIVITE", 
   "FICHE"."DATE_CREATION" "DATE_CREATION", 
   "FICHE"."TYPE_FICHE" "TYPE_FICHE", 
   "FICHE"."FICHE_CREE_PAR" "FICHE_CREE_PAR", 
   "FICHE"."TOTAL_HEURES" "TOTAL_HEURES", 
   "FICHE"."TOTAL_HEURES_EXCEPTIONNELLES" "TOTAL_HEURES_EXCEPTIONNELLES", 
   "FICHE"."DATE_MODIFICATION" "DATE_MODIFICATION"
FROM 
   "FICHE"

The WHERE clause:
WHERE AGENT_ID = ' * ' if nothing is selected.

WHERE AGENT_ID = "4290" If an agent ID is selected.

Hope I'm clear that English is not my mother tongue.

Thanks for you help.
