Declare Variable Data Types

From my understanding, there is no need to declare variables
data type like String, Number, Array for it to function. For
example:
var abc:String = "abcde";
var abc:Number = 1234;
var abc:Array = new Array();
We can write it in easier way and it is still working.
abc = "abcde";
abc = 1234;
abc = new Array();
So, what is the purpose and benefit to declare the variable
specific data type?

i mean that as3 (= actionscript 3) requires variable typing
in most situations or the flash compiler will throw an error.
and no, failing to use strict typing won't cause any
debugging problems.
there's also some "feeling" that strict typing enhances code
efficiency, but i haven't seen anything convincing on this.

Variable Date type

Hello,
I have a date type variable like 05/07/2008 / day/month/year and it works as a string.
I have a prompt with this date type where I have declared a variable called v_date.
The problem is how to make a filter in a form with this variable to see actual year and the previous year.
I have done it many times with other variables like integers or floats like this:
xxxxxxxx IN (@{v_date},(@{v_date}-1))
where v_date is an integer variable type.
I guess I have to convert the string to int with functions like cast and substring to use the formula but it hasn't worked.
Thank you for your help!

Thank you for your answer but still not working.
This is what I have written in my filter of my report:
"Dim Fecha Dia Curso"."Day Date" IN (Right(@{v_date}, 4),(Cast(Right(@{v_date}, 4) as int) - 1))
and that's the error I've recieved:

I need to display the minus value and also the decimal values from a variable..In what data type can i declare..
sample prgm if possible plz

hi
good
there is no specific data type to display the minus value or the decimal value,yes you can declare them as character type and use as per your requirement.

Variable Data Type Error.

I have a fast question. I am setting up a variable with a
data type of Number, when I declare the variable it has a default
value.
I am trying to pass data to the variable from a input text
box but I am getting an error when I run the Movie. I have tried
both a input text box and a Dynamic Text box, but they both produce
the same error.
If I remove the data typing from the variable declaration the
Movie runs and it updates the variable data but from all that I
have read this is not a good practice.
I have attached the code, could someone Please help me out. I
do not remember having these types of problems with ActionScript 2.
Thanks for the help.
Code:
var rectangle:Shape;
var thick :Number = 2; // line thickness
var color:Number= 0x000000; // Holds the color value
myButton_btn.addEventListener(MouseEvent.CLICK, onClick);
function onClick(event:MouseEvent):void
color = colorField_txt.text; (Line 11)
thick = lineThick_txt.text; (Line 12)
rectangle = new Shape();
rectangle.graphics.lineStyle(thick, color, .5);
rectangle.graphics.drawRect(10, 10, 100, 150);
addChild(rectangle);
myButton_btn.buttonMode = true;
ERROR MESSAGE:
1067: Implicit coercion of a value of type String to an

Thanks again for any help.
Mike

the text property of a textfield is of type String, so to
place that String into a variable of type Number, you need to first
convert it to a Number
eg.
thick = Number(lineThick_txt.text);
ActionScript 2 performed this conversion
automatically.

Identify bind variable data type 121?

Looks like the OCI forum is not popular. Reposting here with hopes of better luck... Or perhaps I wasn't specific enough for the forum? OK, this is obviously a binary data type. The problem is that I want to know exactly which of them it is. Or I'd like to know if someone has improperly coded an OCI application. Here's the original post.
I received a level 12 SQL trace file that referenced data type 121 for a bind variable value. I have searched unsuccessfully for documentation in many places. Can anyone tell me what data type this is? Following is the relevant excerpt from the trace file.

Hi
The following are the internal datatypes used by oracle related to 121.
KOTAD, KOTMD, KOTMI, KOTTB, KOTTD
Not sure about their exact use but these datatypes might be used internally for LOB's.
Hope it helps.

OBIEE 11.1.1.6.2 BP1 Repository Variable data type

I have some dynamic DATE variables created which fetches date values from a table. In the table the data type for that field is INTEGER.
But on starting the server all date variables are initialized with .0d appended in the end. LIke 2012.0d etc.
Kindly provide some pointers!
Thanks
KC

Of Course we can do that.
Your substring should not be in init block, it suppose to be where you are referring rep variable.
In your prompt to set default values use sql query something like
SELECT Time."Month" FROM "SA" WHERE Time."Year"=SUBSTRING(VALUEOF("PREVIOUS_MONTH") FROM 1 FOR 4)
If helps pls mark ;)

Shared variable data type: Can I choose an array of a custom typedef, without making the array itself a typedef?

Hi all,
I'd like to pass an array of a cluster across my network. My cluster is typedef'ed, but I'd like to avoid polluting my project with another redundant typedef.
Is it possible to use the shared variable's "From Custom Control..." option with an array, without saving the array as a new .ctl file?
Solved!
Go to Solution.

Ah, I didn't realize you were using shared variables. I thought you were just considering it as another option along with TCP/IP or UDP or something like that. In this case, you would have to create a second custom control. This control would be an array with teh typedef cluster in it. No need to make this new control itself a typedef though. Sorry, I know you were hoping for a different answer. I doubt one file will really "clutter" your project though

Error in getting Long data type from Table

Hi All,
I have one table say xx_long. In this table one column is having Long data type.
Now I want this values will get in to the PL/SQL variable. I taken variable data type as long but it is showing error "ORA-00997: illegal use of LONG datatype".
Sample code with which I tried:
declare
a long;
begin
select slno into a from xx_long where slno = 100;
dbms_output.put_line('Value:'||a);
end;
Please help me on this.
Thanks in advance.

Designer Custom Data Type

Hello,
I've posted a project at some commercial sites to find someone to help me doing it, but couldn't find any. I thought that it might be impossible doing this type of projects. The following is what was posted expecting someone could help/lead me doing it myself or at least providing any valuable hints, Thank you in advance.
Looking for an Oracle expert to do the software part of a project.
A data to be populated in Oracle database, but unfortunately Oracle doesn't support the required data type to hold it.
An expert has to create custom data type with all required procedures/functions to manipulate the data(Read/Update/Insert/Delete), and provide a method to incorporate the solution in Oracle developer suite to model it.(To use it inside designer tools)
The solution should allow someone to Create a column in a table to hold (for example) three bits in every row(record), mostly used in the project is three bits, but need the solution to be open and customizable to any number from one up to 21. Viewing/entering the data in a record could be as binary string. Saving in a table physically should be in sampling way to save space.
The functions/procedures for manipulating the data should be based on record level and block level(several records of one column with start/end points). For record manipulations a binary string should be used, and for block manipulations a sampled structure should be used.
Thank you for your time.
Platforms:
Oracle Database 9i and above.

not sure what exactly do you mean by custom data type in SQL? if you mean if there is a user defined data type in oracle thru PL/SQL yes there is. by using the %Type you need not to declare the variable data type explicitly. all you need to do is associate the variable to the column name of the table and use the %Type. see this example below.
SQL> declare
2    vEmpno   emp.empno%Type;
3 begin
4    select empno
5      into vEmpno
6      from emp
7     where ename = 'FORD';
8    dbms_output.put_line('employee no: '||vEmpno);
9 end;
10 /
employee no: 7902

How to change data type of input parameter

Hi
In my procedure i declared the data type of "Value Date" Input parameter as Date where as in CR it is showing data type as "Date Time". Can any one please specify how to change to Date.
While prompting for input parameter in description it is showing message as
Please enter Date time in format"yyy-mm-dd hh:mm:ss" . To change the content selected "format field" option. But is there any way to change input parameter data type.
Please suggest how to change.
Thanks Sruthi

Hi Sruthi,
all you need to do on this is open the report go to the parameters, select the parameter that you wish to change and click "Edit". This will allow you to change thefield to a date rather than a date time.

Data type in column definition

I create a table with column called "Direction of Travel code ".
The travel codes in the functional spec are numbers.
In the column definition which one is efficient to define the data type as number or varchar?
Code

And then when you issue a query and ask for travel codes 2 through 10 the CBO can't determine that there are 8 values (cardinality wise) because you're not storing the data type in the format you should be storing it as. Statistics? Perhaps even histograms?
Simple testcase:
create table t1(x number(1)) as select mod(rownum, 10) from all_objects where rownum <= 100;
create table t2(x varchar2(1)) as select to_char(mod(rownum, 10)) from all_objects where rownum <= 100;
exec dbms_stats.gather_table_stats(user, 'T1', method_opt => 'FOR ALL COLUMNS SIZE 1');
exec dbms_stats.gather_table_stats(user, 'T2', method_opt => 'FOR ALL COLUMNS SIZE 1');Tried a few simple statements against those (where x = N, where x between N and M), using either literals or bind values. I didn't see any difference in the explain plan...
Not to mention what happens when someone decides to put an "A" in your travel code that should be only numbers, it will eventually happen.Yes, and that's an input error that should be caught by a database constraint (and possibly even before that by the application). Who knows, the codes 0 and 5 might become obsolete as well with changing business rules. Your number datatype is not going to protest when someone still uses them. Hey, maybe even tomorrow someone from the business will come in and demand for the codes 'a' to 'd' to be created. Histograms, application code and database constraints (which all have side effects and add complexity to the system) as opposed to declaring the data type as a NUMBER (which it is). Doesn't seem like a really good argument for intentionally choosing the wrong data type. Well, at least you didn't suggest a trigger in there as well.
>
I'm not saying you should use a char type instead of a number. I'm saying I doubt there's much difference as far as the database is concerned, and I would base the decision on how it works out on the application and business side.As you've found out, the OP stated the functional specs define this as a number. IF in the future the specs change and a business analyst mandates that this support characters as well then the data type gets changed to support the new requirement, no database constraints to remove, no application code to remove, etc...

ALV graph dependency on Data Types.

Hello Friends,
I have to display some fields in the graph option of ALV.For that I need to
declare its data type as Type INT4 or INT2.But in that case I cannot declare it with Decimal places.I can declare it as Type F but in that case I not getting desired display(like 6.130000000000E).
I can use Type P but I am not getting this option when I am doing F4 in data dictionary.So what should I use ,please help me if you have some solution?
