Default value from another table - sql query

I'm trying to make the default value of a text item as the result from an sql or pl/sql statement. I keep getting errors when I try to use a pl/sql statement to do this. Has anyone else done this?

OK, here is what I tried to put in. I have a form and I wanted to add a text field that is derived from another table, such as:
select question from qa_main where seq=:quest_num
So, what I want is to have a form where questions on tests are answered, and I want the text of the question to be brought over from the question table. I'm not sure if I'm using the correct syntax, but the ":quest_num" would be a reference to a question number in the answer table that is linked to the sequence number (primary key) in the questions table.
Of course if there are better ideas, please let me know. :)

Default value from another table in dummy field on a portal form ..

A form based on a table :
id
name
xx_id
I created a dummyfield on the form in which i would like the
name corresponding to xx_id -> I would like to fetch a value
from another tabel into a dummy field.
thanx
Trine Hindsholm

I could do this task by creating the form manually - is there anyway I can modify the insert for a form created by the wizard?

Field with a default value from another field

I need to populate a field as the default value from another field that the user inputs. I've tried the scripting that I found from the below Topic in the Archived Forums, but I'm not able to make it work. I've tried numerous variations and still to no avail. I tried to make the scripting work in Acrobat 6 and then decided that maybe I needed to upgrade, so I'm now trying it in Acrobat 8 with no results. Can anyone help?

Acrobat 5 - field with default value of another field
Ben PF - 03:31am Mar 23, 2007 Pacific
How can I have a field date2 which has the default value of field date1, but which can be edited by the user if necessary without changing the value of date1.
I've tried, but I just can't figure it out!
Any help much appreciated.

This, or some variation of this, should work:
if(this.getField("date2").value == ""{
this.getField("date2").value = this.getField("date1).value;

Thanks very much.
I put it in at document level to start, but it didn't run the script automatically when date1 was first filled in, so I have put it in as a mouse exit action in date1 and it works a treat.
Thanks for your help.

Okay forget what I posted above and lets start over. Go to your first field and under Properties -> Actions Tab -> Select Trigger -> On Blur Run A JavaScript.
Put this:
this.getField("myField2").value = event.target.value;
Make sure that you replace ("myField2") with the actual name of your second field. I just tested this and it works for Acrobat version 6.
I haven't been doing as much javascripting as I used to, so sometimes I too make some basic mistakes.

How to get second maximum salary from employee table(sql query)

how to get second maximum salary from employee table(sql query)

dude there is no matter of structure .........that user already said its from employee table ...............its basic table in sql and there is no need to specify the table structure
.........i think u got my point I think you are the one who didn't understand Sarma's point.
Give a man a fish and you feed him once. Teach a man how to fish and you feed him a life long.
>
and the query is
select max(sal) from emp where sal<(select max(sal)
from emp);
this will give the 2nd max salary from the emp tableBtw: You solution is bad, because it needs to scan and sort the table emp twice. And a better solution has been given already.

How to dynamically get default value from a table column

Hi all,
Here's my problem: Our front end application sends insert and update queries to a pl/sql package. I've got a procedure that gets a PL/SQL table with all the column names an values, a table-name and a primary key name and value. That procedure creates an insert or update statement. So far, so good.
Now the problem: our front end doesn't know what the default value for a column is. So when a number field doesn't get a value in the front-end, it's inserted with a value '0' though is should ben NULL. My sollution for this is to know the default value of a column: when there's a default of '0', then the value that will be inserted is '0'. When there's no default value and the column can ben NULL, it'll be inserted as NULL. if the column has a not null constraint, a '0' will be inserted.
Ofcourse I can get the default value from the system-views all_tab_columns or user_tab_columns, but our application is installed at some 100 clients, and has various database installations. Most of the times, the tables are in the same schema as our procedure that performs the insert or update, but sometimes some of the tables are in another schema (in the same database) and also sometimes some tables are stored in another database. In all these situations, a synonym for that table exists in the schema.
Is there a api function or procedure that I can call to get the default value of a column? I looked at dbms_sql and dbms_metadata, but those packages don't give me that perticular information. if not, I'll stuck with the 'does table exists in schema' yes->use table, no query user_synonyms to look for the owner of the table (and database link) and query all_tab_columns to get the default value. Only this seems a bit overkill to me.
I hope I'm clear enough? And please don't reply with "don't do inserts this way"! I know, this is not the most optimal sollution, but it does gives us a couple of advantages in our application...

there is no way that I can think of, apart from what you have already discovered (i.e. views), where you can determine if a column has a defuault value defined against it.
The other option is triggers, but I guess doing that across 600 tables would not be an option, and besides I stay clear of triggers.
A different approach therefore, if you cannot pre-determine the data, is to consider a post problem handler, hence I suggested the use of an exception handler.
The exception handler works regardless of whether the statement is dynamic or not.
SQL> truncate table abc;
Table truncated.
SQL>

3    pragma exception_init(NULLVAL, -01400);

13          -- handle the error
14          execute immediate 'insert into abc (x,y) values (0,1)';

You might want to write this code in a validator on the entity object if it should apply from every screen.
If you want to access view objects from a backing bean the basics are here: http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcservices.htm#sthref918

Ain't getting it: insert into table by determing value from another table

I have a table (PERCENTILE_CHART) with percentiles and test scores for different tests:
Structure:
Percentile, Reading_Test, Writing_Test
Data:
30,400,520
31,450,560
97,630,750
98,630,780
99,640,800
The data is currently in ascending order by Percentile.
If a person took the Reading test and scored 630 he or she would be in the 98th (not 97th) percentile of the class taking that test.
I wrote a statement to return the percentile:
select Percentile
from ( select ROWNUM, PERCENTILE
from PERCENTILE_CHART
where READING_TEST <= '650'
order by READING_TEST desc)
where ROWNUM < 2 order by PERCENTILE desc;
This select works and is able to determine the highest percentile for a score.
Ok, now I want to process all the records in a STUDENT table which have
test scores and insert them in a new table along with the percents, normalizing the data in the process.
Have this:
STUDENT:
Student_Name,Student_ID,
John Smith,121,Reading,98,Writing,90
Maggie Smithe,122,Reading,95,Writing,96
And needs to be moved to into SCORES with the percentiles, so I get this:
SCORES:
Student_Name,Student_ID,Test_Name,Percentile
121,Reading,98
121,Writing,90
122,Reading,95
122,Writing,96
This is were I get confused. How do I insert the data into the SCORES table with the percentile? I think calling a function in package is the way to do it:
function oua_Test_Percentile_f (
p_Test_Name in char,
p_Test_Value in char)
return char as
-- Declare variables
c_Return_PTile char(2);
begin
select PERCENTILE into c_Return_PTile
from (select ROWNUM, PERCENTILE
from PERCENTILE_CHART
where p_Test_Name <= '&p_Value'
order by p_Test_Nmae desc)
where ROWNUM < 2 order by PERCENTILE desc;
return c_Return_PTile;
end;
But this function doesn't return the percentile even though it is based on my working select mentioned earlier. It returns a blank for all tests.
And even if it is working how do I then populate the SCORES table?

You may want to use analytical functions so that you can determine the percentile across all of the different scores:
SQL> with
2 PERCENTILE_CHART as
3 (
4 select 30 PERCENTILE, 400 READING_TEST, 520 WRITING_TEST from dual union all
5 select 31 PERCENTILE, 450 READING_TEST, 560 WRITING_TEST from dual union all
6 select 97 PERCENTILE, 630 READING_TEST, 750 WRITING_TEST from dual union all
7 select 98 PERCENTILE, 630 READING_TEST, 780 WRITING_TEST from dual union all
8 select 99 PERCENTILE, 640 READING_TEST, 800 WRITING_TEST from dual
9 )
10 select
11 max(percentile) over (partition by reading_test) HIGHEST_READING,
12 max(percentile) over (partition by writing_test) HIGHEST_WRITING,
13 percentile_chart.*
14 from
15 percentile_chart
16 /
HIGHEST_READING HIGHEST_WRITING PERCENTILE READING_TEST WRITING_TEST
30 30 30 400 520
31 31 31 450 560
98 97 97 630 750
98 98 98 630 780
99 99 99 640 800
SQL>
I wasn't exactly sure how you wantd to coorelate this to the student records though; the student table had only two column name headings but there were four rows listed as examples and had fewer rows than in the percentile_chart table...
If you join the student table to the able query it might be what you are looking for.
You can create another table based on the output of your query by doing:
create table scores
as select * from
(insert your query here)

Validating Tabular Form Column Against Value From Another Table

Hi,
I am brand new to this forum, so please bear with me a little! I only have a small amount of experience writing PL/SQL, and I've never written Javascript or JQuery before. I am an Oracle DBA, and I have coding experience in C and PERL, so I do have a solid technical background. But, I need some advice on the best way to approach a problem.
I have a database application in Oracle Apex (version 4.2) with a tabular form against a table: let's say Table #1 with cols 1A, 1B, and1C. I need to ensure that the value entered into col B isn't greater than the value of a column in another table (let's say Table #2 col 2A). Conceptually, the amount of money available is in Table #2, and the rows of my tabular form are an act of spending money (like orders or invoices), so I need to make sure we don't spend more than we have. Does that make sense?
Does anyone have any advice for the best way to do this? I'm figuring the biggest issue here might be that we have to account for people entering mutliple rows in the tabular form at one time, right? So, if a person entered 3 orders/invoices, I need a total to make sure they didn't spend more than we have in Table #2.
I greatly appreciate your help!
Best Regards,
Laurie Baublitz

Hi!
You need one process of type ajax callbacks like:
DECLARE
   l_limit nubmer;
   l_number1 number := apex_application.g_x02;
   l_returnValue VARCHAR2(200);
BEGIN
   select A2 into l_limit from table2;
   if l_number1 > l_limit then
      l_returnValue := 'LIMIT IS NOT SO BIG';
      if l_returnValue is not null then
         --this will write l_returnValue to the buffer, and the ajax callback will receive this
        htp.p(l_returnValue);
      end if;
end if;
END;
Then you need one javascript on page, code is something like:
$('input[name=your column in tabular which is change]').live('change', function(){
   //if value of changed field differs from an empty string
   if($(this).val()!=''){
      //put target element in a var to reference it in the ajax success callback
      var num = $('input[name=your column in tabular with value]');
      $.post('wwv_flow.show',
             {"p_request"      : "APPLICATION_PROCESS=your ajax callback function",
              "p_flow_id"      : $v('pFlowId'),
              "p_flow_step_id" : $v('pFlowStepId'),
              "p_instance"     : $v('pInstance'),
              "x01"            : $(this).val(),
              "x02"            : $(num).val()
              function(data){
                 if(data !=''){
                 alert(data);
I can not guarante that code is 100% working, if not you need to do some changes or make an example on apex.oracle.com and provide credentials here.

Dynamic Column Names from one table and its corresponding values from another table

I have 2 tables. First tables gives the specification if a column is required or not. we have the 2nd table with the same column name where we provide the actual values.
I want to select all the required columns from the 1st table and retrieve the values for those from the 2nd table. Both this i want to achieve in a single select statement.

This wil require a dynamic Query with a Pivot
DECLARE @ColsPivot as VARCHAR(MAX);
DECLARE @Query AS VARCHAR(MAX);
1. Retreive the ID for all required field
SET @ColsPivot = (SELECT STUFF((SELECT ',' + quotename(CAST([RequirementID] as varchar(3))) FROM [dbo].[Requirement] WHERE required=1 FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,''));
This will give you : [1],[2],[3],[8],[9],[14] for exemple.
2. Build your Query
SET @Query ='SELECT ClientID,'+@ColsPivot+''
   FROM (
       SELECT [ClientID],[RequirementID],[Value]
       FROM dbo.RequirementValue
       WHERE ClientID=@CliendID --Optional SP parameter
   )src
         PIVOT(
           MAX(Value)
           for [RequirementID] in ('+@ColsPivot+')
   ) p';
3. Exec(@Query);

How to update this table with values from another table ?

Hi
I have a table "regies". I want to replace the values of the column "regies.agent" by the value of the column "regies_personnes.id"
As you see the tables have a common values column. ie regies.agent = regies_personnes.nom
Table "regies" :
Insert into "regies" (AGENT) values ('Humberdot Alain');
Insert into "regies" (AGENT) values ('Danard Patrick');
Table "regies_personnes" :
Insert into REGIES_PERSONNES (NOM,ID) values ('Humberdot Alain',1);
Insert into REGIES_PERSONNES (NOM,ID) values ('Danard Patrick',2);
Before we have this
sql>select agent from regies ;
Humberdot Alain
Danard Patrick
After the update, the result should be
sql>select agent from regies ;
1
2
Thank you for your kind answer.

You will face error if you have duplicates
ORA-01427 Single row subquery returns Multiple rows.Try this way
create table regies(agent varchar2(30));
create table regies_personnes( nom varchar2(30),id number);
Insert into regies (AGENT) values ('Humberdot Alain');
Insert into regies (AGENT) values ('Danard Patrick');
Insert into REGIES_PERSONNES (NOM,ID) values ('Humberdot Alain',1);
Insert into REGIES_PERSONNES (NOM,ID) values ('Danard Patrick',2);
Insert into regies (AGENT) values ('Humberdot Alain');
Insert into regies (AGENT) values ('Danard Patrick');
Insert into REGIES_PERSONNES (NOM,ID) values ('Humberdot Alain',1);
Insert into REGIES_PERSONNES (NOM,ID) values ('Danard Patrick',2);
commit;
update regies r set agent = (select id from regies_personnes p where r.agent = p.nom
and rownum=1)
where exists (select id from regies_personnes p where r.agent = p.nom

Id from one table showing value from another

I have an article id (rs_comments.id_com) but I would like it
to take this data and collect the value from another table.
I have joined the two tables with:
SELECT * FROM blg_comment_com INNER JOIN blg_article ON
idart_com=id_art
WHERE valid_com=1
ORDER BY date_com DESC
rs_comments.idart_com needs to be equal to rs_comments.id_art
displaying the value from rs_comments.title_art
How would I go about doing this. There only seems to be an
option in DW to do this with a dynamic list/menu but I just want to
display the text without option to change it.
Any help much appreciated.

Breakout table (fill table with matching data from another table)

Hi
I've been trying to study old discussions about breakout tables. I feel I'm close, but still no cigar :-)
In plain english, I'm trying to autocreate rows with data on a table, based on matching values from another table. E.g. have a table to display all rows where type = AssetX
I have attached a screenshot of my "master table" called Assets:
I'm looking to prefill Asset name, Total from this table and populate a new table called e.g. Greenhouse
Where I'd be adding more data (date, income, expense).
Any help whould be greatly appreciated.
Thanks!

Set Default Value based on Field from another table for a custom object

I'm trying to set the default value on a custom object field to the value of an account field. I have tried the syntax 50 different ways, and just am getting no where. The account field label displays as DBA, the integration tag is ltDBA_ACCT, and it shows up in reporting fx area as Account.Text_22.
The custom object field I'm triying to update is also called DBA, which was originally the "NAME" required field. Does the table name, Account, have to be included? Do I need a function in front of the field?
I have been updating the external ID using the row ID with syntex <ID> (Less than ID greater than) so I know it is possible to set the Default Value, but <DBA>, <ltDBA_ACCT>, "Account"."DBA", and so on just don't not work.
If anyone knows how to enter this I'd really appreciate the help.

Ok, so if you want to default a field to the value from another object, you have to use the JoinFieldValue function. I think you understand that, based on your original post, but I want to be sure that you do.
Next, this will only work as a default if the record is created from the object that you wish to join on because a default works at record creation and the ID needs to be available for it to work properly. It will not work if you choose the related object record after the custom object record is created. You could set the value as a post-default, but that does not seem to meet your requirements.
The syntax for the Default Value would be as follows: JoinFieldValue(ref_record_type, foreign_key, field_name).
In your case, ref_record_type is '<Account>', foreign_key is [<AccountId>], and field_name is '<YourFieldName>'. The best way to determine what the field name is would be to create a new workflow for Account and use the Workflow Rule Condition expression builder to pick your field ("DBA") from the list. The value that is returned by the expression builder should be placed in the field_name variable in the JoinFieldValue function (minus the brackets and in single quotes).
Give this a shot and let me know how you do.
