Null and no data in field value

I transferring sql from MS Access to Oracle 9i.
In Access I have this
select * from tableOne where firstname <> ''
and firstname & '' = ''The firstname field can be edited where it could have data and the data could be deleted so I am trying to select records where firstname is not null and it has no data in it.

select * from tableOne where firstname IS NULL;
- or -

as appropriate.
In Oracle there is no difference betwen being NULL and having data of length '0'

How to calculate a date in the future and set it as field value?

I'm trying to set the value of a read-only field to a date and time 72 hours from the current date and time. Here's how I'm doing it now:
var futureInMilliseconds = new Date().getTime() + 259200000; // current date and time + 72 hours in milliseconds
field.value = new Date(futureInMilliseconds);
The field is formatted as "m/d/yyyy h:MM tt". When I test this in the debugger I see it listing the correct date and time in the future, but the value applied to the field is always the current date and time. So, I'm having a difficult time getting this to work for something that should be fairly straight forward and simple. I'd appreciate any suggestions.

What is the "field" object?
What happen when you use "event" for the object and not "field"?
Even if this script is placed at the document level or any other location, it is still a calculation. It just not a field Custom Calculation Script. You are adding one value to another to get a new value.

How to Update Date data type field value in oracle

I want to update records in a table that has a Date data type field. It's a oracle databse. I use the oracle thin drive to connect to the database. The everything works well, only when i try to update records that have date type value, something doesn't work.
I use the following stmt to update DB:
Class.forName("oracle.jdbc.driver.OracleDriver");
Conn = DriverManager.getConnection("jdbc:oracle:thin:@hostname:portnumber:schname", "uid","pwd");
stmt=Conn.createStatement();
String updStr = "UPDATE Article SET Archive = ' Disable' WHERE ArticleDate = # " + sqlDate +"# " ;
stmt.executeUpdate( updAStr ) ;
But I always got the SQLException run time error, which is "ORA-00911: invalid character"
Who can help me to find out how to write the above Update statement correctly? esp. that how to present the Date type variable in the statement.!
BTW, sqlDate is a Java.sql.Date variable, Is it "# " + sqlDate + "# " the right way?
Many thanks

What do you get out of Oracle's TO_DATE that java.sql.PreparedStatement.setDate()
won't give you? - MODWell, I don't know that I've used all capabilities of either, but when it comes to managing Date Strings my Oracle bias :) would be to code using Oracle's TO_CHAR and TO_DATE functions. Perhaps someone can tell me vendor neutral ways to do something simiilar to managing these input date/times (and hopefully just as easily, pretty much all done in a single line, single function)?
WHERE aDATE > TO_DATE('2010','YYYY')
WHERE aDATE > TO_DATE('2010 AUG 22','YYYY MMM DD')
WHERE aDATE > TO_DATE( 'January 15, 1989, 11:00 A.M.', 'Month dd, YYYY, HH:MI A.M.')
I believe most databases have something similar to this, although I have found Oracle's to be the most flexible and consistent, if not the most intuitive. Other vendors (DB2, SQL Server, Access) don't force you to always be explicit, and can accept a variety of date strings without masks. The problem is that while you might not be getting an error, it also may not be parsing your date as expected.
One could argue that this vendor specific hodgepodge of literal date/time strings is only one program modification away from disaster. They might be right.
Just to be clear. I'm not recommending using a vendor specific approach, but it's not a perfect world and somtimes you have to use what works easiest or best or fastest, and in some cases, that is the vendor specific alternatives.

Problem while creating with QUAN and CURR data type fields

I am trying to create a Z table. A couple of fields are of data type QUAN and CURR, which need to have reference table and reference field.
Field               DataType     Length     Decimal
TOT_QTY       QUAN            15                 3
PRICE              CURR             16                2
For reference table and fields, I found a Table HRPAD23 which has a field called N_QUANTITY (15,3) that matches my TOT_QTY field's data type and it also has a field called UN_PRICE that matches my PRICE field's data type. But when I use them as reference, and try to activate the table, I get an error "combination reference table/field does not exist". How do I fix this? Can anybody help me? Thanks in advance.

Martin,
I doubt that you need to add 2 extra fields in your table as suggested in the last post by John.
Your error is very CLEAR that you seem to be use wrong combination of reference table and field.
For QTY field,
use ref table - HRPAD23.              ref field- UNIT
OR
ref table - VBAP                       ref field - VRKME
For PRICE field,
use ref table - PAD25                  ref field - KWAER
OR
ref table - T77REFDOC                                     ref field - CURRENCY
It should work.

Formula in Fields and get data from fields together

Hi, I was trying to setup formula in fields as follows:
U_Test & U_Test are numeric fields.
SELECT ($[INV1.U_Test.Number]-$[INV1.U_Test3.Number])*0.1
The outcome should be (U_Test-U_Test3)*0.1
U_Test2 & U_Test5 are alphnumeric fields.
SELECT $[INV1.U_Test2]+[INV1.U_Test5])
The outcome should be U_Test2U_Test5
I have been struggling in the syntax error. Can you help me out?
Thanks.
Raymond

I think better u can create the UDF again.
Test - Numeric - 10
Test1 - Numeric - 10
Then use this query
Select $[$38.U_Test.number] + $[$38.U_Test2.number]
I hope UDF can be case sensitive. It is working properly for me.
Sample:
Select case when ($[por1.U_x.number] *$[por1.U_y.number]) > 15 then 15 else ($[por1.U_x.number] *$[por1.U_y.number]) end
here x,y are UDF created as numeric.

Bug alert re iMT Extraction tool and custom data/display fields superclasses

In the current iMT there is a Extraction tool bug whereby custom
superclass usage in NetDynamics displayFields and/or dataFields are
resulting in nodes being omitted from the
application description. Worse, this omission was not being detected
by the Extraction tool. The error would not surface until the
Translation tool ran and tried to use the incomplete application
description xml file. The translation tool would then error as it
tried to locate non-existant nodes.
This is a serious problem for those applications which make use of
custom superclasses for displayFields and/or dataFields. If the
extraction omits these nodes, then the information is not available
to be translated. The problem is so severe, that I assume no one out
there has encountered it, or they would have reported it to us. If I
am mistaken in this assumption, please contact us.
The problem was easily corrected once identified. A fix will be
included in the next general release of the iMT.
At this point we are holding off on releasing micro-patches, in
anticipation of releasing a comprehensive iMT 1.1 release in the near
future.
If you have urgent need for this fix or any others that have been
listed on these boards, since the last patch drop, please let us know
ASAP and we will see what we can do.

I, for one, appreciate your contribution to this forum.
I haven't used Ultiboard since my initial purchase of it many many years ago. (MultiSim was bad enough. I wasn't about to start fighting with UltiBoard also.) However, it's of note how may bugs you have open/unsolved. MultiSim Inc has definitely not done its homework. In my case, that's not so much of a loss, but based on what you're saying, you actually have to use this thing to make money! That stinks!
I have little grounds for filing suit, as I've taken little risk; although, I can't tell you how many hours I've burned trying to figure out MultiSim's latest burp, that's hardly grounds for benefit from a suit. But you however, you're losing money! I'm thinking that the "at your own risk" in the fine print is MultiSim's out, but this is just wrong, the way this company is. This program just doesn't work and it looks like little can be done about it.
I thought that National Instruments' involvement would get some where with this program, but thus far that's proving to be an error on my part. My latest bug is the inclusion of MultiSim's multimeter causes a circuit to stop simulating. I mean how ridiculous is that?! But at least when MultiSim burps for me I'm not losing money, just time.
Thanks again for starting this thread!

How do you calculate difference in time (hours and minutes) between 2 two date/time fields?

Have trouble creating formula using FormCalc that will calculate difference in time (hours and minutes) from a Start Date/Time field and End Date/Time field.
I am using to automatically calculate total time in hours and minutes only of an equipment outage based on a user entered start date and time and end date and time.
For example a user enters start date/time of an equipment outage as 14-Oct-12 08:12 AM and then enters an end date/time of the outage of 15-Oct-12 01:48 PM. I need a return that automatically calculates total time in hours and minutes of the equipment outage.
Thanks Chris

Hi,
In JavaScript you could do something like;
var DateTimeRegex = /(\d\d\d\d)-(\d\d)-(\d\d)T(\d\d):(\d\d)/;
var d1 = DateTimeRegex.exec(DateTimeField1.rawValue);
if (d1 !== null)
var fromDate = new Date(d1[1], d1[2]-1, d1[3], d1[4], d1[5]);
var d2 = DateTimeRegex.exec(DateTimeField2.rawValue);
if (d2 !== null)
var toDate = new Date(d2[1], d2[2]-1, d2[3], d2[4], d2[5]);
const millisecondsPerMinute = 1000 * 60;
const millisecondsPerHour = millisecondsPerMinute * 60;
const millisecondsPerDay = millisecondsPerHour * 24;
var interval = toDate.getTime() - fromDate.getTime();
var days = Math.floor(interval / millisecondsPerDay );
interval = interval - (days * millisecondsPerDay );
var hours = Math.floor(interval / millisecondsPerHour );
interval = interval - (hours * millisecondsPerHour );
var minutes = Math.floor(interval / millisecondsPerMinute );
console.println(days + " days, " + hours + " hours, " + minutes + " minutes");
This assumes that the values in DateTimeField1 and DateTimeField2 are valid, which means the rawValue will be in a format like 2009-03-15T18:15

Deleting a Date/Fields value

Hi I'm developing a XDP Form to be depolyed under XHTML, and I cannot find a way to clear a Date/Time Fields current value using Javascript.
I've tried fieldname.rawValue = "", fieldname.value = "", and fieldname.formattedValue = "", and = null for all properties mentioned. These do seem to visually remove the date's value (or put the string "null"), However when a server side script tries to read the value (should be empty) from the date/time field it still returns the original date value.
I've also tried combinations of xfa.host.resetData(), which only partially works if the date field had an original value of empty not if it was populated with a value, plus it seems to clear all the other fields on the form which is not desireable.
Is there any way to delete the Date/time fields value client side?
Any ideas would be greatly appreciated?

Avoiding null and duplicate values using model clause

Hi,
I am trying to use model clause to get comma seperated list of data : following is the scenario:
testuser>select * from test1;
ID VALUE
1 Value1
2 Value2
3 Value3
4 Value4
5 Value4
6
7 value5
8
8 rows selected.
the query I have is:
testuser>with src as (
2 select distinct id,value
3 from test1
4 ),
5 t as (
6 select distinct substr(value,2) value
7 from src
8 model
9 ignore nav
10 dimension by (id)
11 measures (cast(value as varchar2(100)) value)
12 rules
13 (
14 value[any] order by id =
15 value[cv()-1] || ',' || value[cv()]
16 )
17 )
18 select max(value) oneline
19 from t;
ONELINE
Value1,Value2,Value3,Value4,Value4,,value5,
what I find is that this query has duplicate value and null (',,') coming in as data has null and duplicate value. Is there a way i can avoid the null and the duplicate values in the query output?
thanks,

Adobe Acrobat as a server to create PDF using PDF templates and field values

I'm writing a web page to create a PDF using fields that we ask for them in the screen.
My idea is:
1. Ask for field values (text values and a photo) in my web
2. Run Adobe Acrobat to load a PDF template (PDF form) and mix with the field values
3. Create a final PDF mixing values and template
4. Show to document to the user in his client web browser. I guess the only way to do that is to create the PDF on a server with Adobe Acrobat Pro and send to the user browser a JPEG that will represent the PDF: If I do this operation in the PDF visor at the client browser, the problem is that it will will be mandatory to install Adobe Acrobat in each cliente because only this visor can manage javascript.
Can you tell me if this idea is correct? It is possible to use Adobe Acrobat on a Server to create PDF when some proccess needs?

and what other Adobe product o procedure can we use to do that?
I only need to create a PDF mixing PDF Templete, field values and javascript.
Thanks for your help.

How to compare Date in the TextField or DateTime with Date/Time field?

Hi All,
I am facing an issue with respect Date comparinson. I tried to look into entire discussions but failed to get the answer.
My issue is: I wanted to comparet Date/time field value with Date value which is in TextField.
The functionality of my form is:
I have dropdown list which lists the registered customer ids binded to XML Datasource. On selection of the customer id from the dropdown I am displaying customer registration date in the TextField or say Date/Time field as below code in dropdown change event.
RegistrationDetails.PurchaseEntry.txtRegDate.rawValue = regDataNode.CREATION_DATE.value; (this is TextField control)
In form I have an Date/Time field in which use will select the date of item purchase. In the validation part I want to make sure that, the purchase date selected in Date/Time field must be greater than the Customer Registraiton Date. I able to compare if the customer selects the date from two different Date/Time fields. But how to compare the dates which one is in Date/Time field and Date is in TextField?
I have tried using Num2Date and Date2Num with "YYYY-MM-DD" format to compare but not succeed!
Can you guys help me in this? Thanks in advance
Regards.

Hi,
Yes, I am able to display the date which I have assigned to the text box. In the message box it show the value as '31/05/2009', since in this format i am assigining the date in the text box.
Here is the code which I am assigning the value:
RegistrationDetails.PurchaseEntry.txtRegDate.rawValue = regDataNode.CREATION_DATE.value;
Do I need to change the format while assigning value in text box?
You have told that, you have attached your test form, nothing is the reply. Can you repost the file?
Regards.

Joining tables with "similar" field values

I have run into a situation where I want to join two tables on a field called U_LotusBox.    In my main table the the feild can contain values like 1 or 2 or 3 or 1,2,3,4. That's 1 comma 2 comma 3 comma 4. My field in the second tables contains only single digit values, like 1 ,2, 3 up to 5.
When the two fields are identical I am able to retrieve data. But if my field in the main contains a value of 1,2,3 and my secondary table field value is 2 I get no data returned because the two fields are not identical.
Is it possible to have a join that is "fuzzy" meaning that if the main table field values contains the value of the secondary field value, 2 in my example would it be possible to return data?
Any thoughts would be appreciated.

Ralph,
Here in high-level details is an SQL example of creating two tables (test1 and test2) with one column in each table (col_a and col_b, respectively) to show how a join on a substring of one column can be tied to a column of another table:
create table test1 (col_a char(5))
create table test2 (col_b char(1))
insert into test1 values ('1')
insert into test1 values ('1,2,3')
insert into test2 values ('1')
insert into test2 values ('2')
select col_a,test2_tbl1.col_b
from test1 inner join test2 as test2_tbl1 on col_a=test2_tbl1.col_b or
substring(col_a,1,1)=test2_tbl1.col_b or
substring(col_a,3,1)=test2_tbl1.col_b or
substring(col_a,5,1)=test2_tbl1.col_b
col_a     col_b

Two fields, two scripts. User can enter data into field 1 or 2

Hi all,
New here, and to acrobat forms, so please bear with me!
What I'm trying to achieve is a form that calculates total invoice value, based on a total number of hours worked, and a rate. The user fills in the total hours, but then the problem is that some people know their fixed rate, and others have a changing rate. Those with a changing rate simply know the amount they are invoicing for. What I'd like, is a way for the TotalInvoice value to be calculated by Rate*TotalHours when the user enters a value into the Rate field... OR ... for Rate to be calculated by TotalInvoice/TotalHours when the user enters a value into the TotalInvoice field.
I can make it go one way or the other (so the script is only in TotalInvoice field or the Rate field), but I can't manage to get it to go both ways. Is this possible?
To summarise: User can enter manually into Field1 and value of Field2 is calculated, or user can enter manually into Field2 and Field1 is calculated.
Thanks!

What you propose can be difficult, becuase you're describing a circular reference between the two fields. When the 1st value changes, you want the 2nd value to be calculated based on the 1st value. But when the 2nd value changes, you want the 1st value to be calculated based on the 2nd, ad infinitum. There are ways to short-circuit the loop, but it depends on whether you need to do the calculation only when there is manual entry, or whether you need it to work when either field value changes programmatically or by importing form data.
Sometimes it's just easier to have the user press a button to calculate and set the other field value.
