Auto number as a data type?

Hello,
Is it possible in Oracle to use an auto number (integer) to automatically give a number for a column such as ID whenever a record is created or inserted? This would be similar to MS Access.
TIA.

There has been some debate (both within NI and with customers) about whether or not the flattening/unflattening solution is actually desirable. After all, if NI made the shared variable support classes, to do the writing to the variable, the object would be flattened to a string and then unflattened when the variable is read. In other words, having the shared variable support classes does not actually remove any work that the program has to do, so having the shared variable do this behind the scenes is just syntactic sugar. The negatives crop up with the issues that Phillip raised -- suddenly the shared varible is reporting a number of errors that it did not support previously, whereas by separating the (un)flattening into a separate node, it is easier to tell where an error is arising -- was it a failure to read a shared variable or was it a failure to unflatten the data therein? By keeping the shared variable ignorant of such complex data types, it is easier to swap out the communication mechanism used -- shared variables might get support for LV classes, but TCP/IP prims might not, or whatever other communication protocol comes along in the future (i.e., the network stream primitives that are brand new in LabVIEW 2010 -- effectively queues that are usable over the network).
Users may choose to create a custom string format for objects, one that can be unflattened by any system that uses the shared variable -- including CVI and MeasStudio. Having shared variables support classes directly does not get in the way of this, but consideration of exactly what private fields actually need to be exposed in that very global global variable might be encouraged if users are consciously aware of the serialization taking place.
I'm not pro or con this feature at this point... this post is merely to document debate I've heard about any intermachine communications protocol handling LV classes directly.

ORA-01722: invalid number error - column data type is date

Hi all,
When I perform this statement everything is ok, but some of clientbirthday values are null:
select d.id, d.name, d.contragenttypeid, d.reestrtypeid, d.clientbirthday
from creator.contragent d
where d.contragenttypeid = 3
and d.reestrtypeid in (2,4) When I'm trying to get "d.clientbirthday is not null" I receive error:
select d.id, d.name, d.contragenttypeid, d.reestrtypeid, d.clientbirthday
from creator.contragent d
where d.contragenttypeid = 3
and d.reestrtypeid in (2,4)
and d.clientbirthday is not null ORA-01722: invalid number
What is wrong? Why does it say "number" when clientbirthday column datatype is date ?

Can you make a desc creator.contragent

How to use auto increment with "nchar" data type

Hello
I have a table that I want the value in one column to be generated automatically with "T-XXX" pattern which
"XXX" is a number. Can Microsoft SQL Server do that?

Hello,
Not directly.
You could use an integer column with "Identity" and then add a calculated column to generate the required pattern, like
'T' + convert(varchar, YourIntColumn)

I am new to Teststand software interface. While doing my first software release under the guidance of a more experienced colleague, we discovered that Teststand will not run if it detects version number conflicts between custom data types on my machine vs. the production test machine. I verified differences between all .seq files in my test program directory, but I did not realize that the version number difference exists in the StationGlobals.ini file, which is stored in a different location. After discovering this, I modified the version number in one of the files. However, two releases later, I discovered that the version number mismatches in another two files. This raises several questions for me :
1. Is there a way in Teststand to view all the .seq files where a custom data type is used and then change its version number in one attempt?
2. Under what instances does Teststand upgrade the version number of a custom data type?
3. Are there any tools or scripts within Teststand that can allow the version number of custom data types to be changed in all .ini files when a difference is discovered between the current production test station settings and a new release?
Please help.

Have you read this? http://zone.ni.com/devzone/cda/tut/p/id/7060
I can tell you that your situation is not uncommon with TestStand. The key is just doing it right the first time. haha
#1- I doubt that this is possible because then TestStand would have to know every location of every .seq on the machine. You will only see it when you open the sequence file.
#2- TestStand updates the version every time you change it. You should get a message popup when you try to save that asks if you want to increment the version or not. There's also a check box that says Remove Modified Mark From Types. Look under Station Options in the File tab. There are some settings there about Type conflicts.
#3- http://zone.ni.com/devzone/cda/tut/p/id/7910

You'll probably get better response in the TestStand Forum instead of the LabVIEW forum.
1. Is there a way in Teststand to view all the .seq files where a custom data type is used and then change its version number in one attempt?
Look at the Types Window (Ctrl-T). This should show which version of Custom Data Types are loaded for which sequence files.
2. Under what instances does Teststand upgrade the version number of a custom data type?
As far as I know, anytime you edit a custom datatype which is already in memory, TestStand will update the version of the custom data type for the currently loaded sequences.
3. Are there any tools or scripts within Teststand that can allow the version number of custom data types to be changed in all .ini files when a difference is discovered between the current production test station settings and a new release?
I think you can use the Types Window to do this but I'm not positive.

Cannot get the correct data type in Oracle JDBC

Dear ALL:
I used JDBC ResultSetMetaData to get the column data type for Oracle Database. I created a table including 2 columns AAA, which is NUMBER type, BBB which is FLOAT type.
However, I found a problem that either NUMBER or FLOAT data types are reported as NUMBER type in JDBC.
IN SQL 2000, it is okay. SMALLINT, INT, TINYINT, etc..can be reported correctly.
Can anybody tell me that what's wrong here? I will be very appreciated.

hi,
i guess its a bug which is fixed with 10i.

Place a string before a data type when creating a column in a new table

Hi,
I am trying to create a table in Oracle 10g called Penalty with the following Primary Key; PenaltyType. I wish to insert the word 'penalty' and a single number into each column without creating a sequence, for example penalty1, penalty2, penalty4, penalty9 etc with the number input by the user and the database automatically inserting the word before it.
I am not sure about how I go about creating this as a constraint on the data type, could anyone possibly enlighten me?
I am using code which forms part of a larger SQL script to create a car hire database as detailed below;
CREATE TABLE Penalty
(PenaltyType ???????????????
CONSTRAINT pen_PenaltyType_pk PRIMARY KEY (PenaltyType),
MinDay NUMBER(3),
MaxDay NUMBER(3),
Cost NUMBER(2, 2));
Where the question marks would be replaced by the inserted word and single number to meet data type constraint:- "The word penalty followed by a single number (eg. Penalty1) "
Any help would be most appreciated, hope it's not too confusing, and sorry about formatting but the forum left justifies it all.
Thanks,
Jason

SQL Insert Statement Data Type Mismatch Error

I am doing a very simple web application that has a Microsoft Access database as the data source. I have been able to sucessfully create update and query statements using parameters but am having issues with an insert statement. I am using JSTL 1.1.2
The following code creates the data type mismatch error.
<sql:update
     sql="insert into tblTtoF(TFToolID,TFFeatID) values(?,?)">
        <sql:param value='$(ID}'/>
     <sql:param value='${feature}'/>
        </sql:update>The table has NUMBER as the data type for both of these fields and the variables I am feeding into it are both numbers. If I hard code the first number into the sql statement then it works. I have tried swapping the variables around and as long as the first one is hard coded the parameter for the second one works no matter which is first or second.
However I can get the following code to work, which of course leaves me vulnerable to sql injection attacks which is not really a good thing.
<sql:update>
     insert into tblTtoF(TFToolID,TFFeatID) values('<c:out value="${ID}"/>','<c:out value="${feature}"/>')
        </sql:update>So I am just looking for any suggestions as to why my first piece of code doesn't work seeing as it is the simplest of SQL statements and the most standard syntax.
Thanks

I changed it to the following
     <c:set var="featurenew" value="${0 + feature}"/>
     <c:set var="IDnew" value="${0 + param.toolID}"/>
          <sql:update
          sql="insert into tblTtoF(TFToolID,TFFeatID) values(?,?)">
          <sql:param value='$(IDnew}'/>
          <sql:param value='${featurenew}'/>
          </sql:update>And got the following error in the localhost.log

How to add a UDF with picture data type by using metadata object?

Hi guys,
does anybody have a clue on how to code user fields metadata object (via VB6) in order to add a picture type field? I can't find the enum number for this data type in the DI help file.
Best Regards,
Oki

Hi,
The field type should be BoFieldTypes.db_Alpha , and the subtype BoFldSubTypes.st_Image .
And it is in the DI documentation (look at the SubType property).

Is there a auto-increment data type in Oracle

Hi,
I think you need unique ID's, for this purpose you use sequences
in Oracle. Example:
create table xy (
id number,
name varchar2(100)
alter table xy
add constraint xy_pk primary key(id);
create sequence xy_seq start with 1 maxvalue 99999999999;
(there are many other options for create sequence)
create or replace trigger xy_ins_trg
before insert on xy
for each row
begin
select xy_seq.nextval
into :new.id
from dual;
end;
This produces a unique value for the column id at each insert.
Hope this will help.

Issue with the Data Type 'Number' in Business Objects

Hi,
I have an Object in the Universe where the Data Type of the Object is a number. This Column pertaining to this Object has certain values in the database out of which there is a 17 Digit Value which is 00000000031101165.
Now, when trying to retreive the same value through Business Objects it is getting rounded off to 00000000031101200 automatically when trying to view in Webi and when trying to retreive the same in Designer/Deski, it displays as 0.000000003110116E+16.
So, I would like to know if there is any other alternative in trying to retreive the Original Value that would not round off. Also, do we have any Limitation for the Data Type Number in Business Objects? The Version we are on is XI3.1.
Note: There are no functions that are used on this Object at the Universe Level and would not like to use any functions here.

What is the underlying database?
It looks like the data is considered to have two decimals, but is rounded to zero decimals.
Only you don't see the number formatting.
Is this a BW query?
Is this a calculated keyfigure?
In the query you can specify the rounding you want and it is also possible to specify it on an infoobject level.
Check those settings...
Hope this helps,

PS. Oh, and about the formatting, you can specify a default object format in the universe and override it on the final client (WebI, Crystal)

Issue with field data type NUMBER(22,5) while updating field data.

Hi,
I have a field with data type NUMBER(22,5).
While inserting or updating field data it should take 17 digit and after decimal point 5 digit total 22 digit.
I set 22 for maximumLength property of messageTextInput field.
While updating field I am getting following problems,
1) I provide the value as 1234567890123456789012 (22 digit) and click apply button.
then I got error message as
Error
मैकेनाइजड दो पहिया/तीन पहिया वाहन - Value 1234567890123460000000 exceeds the maximum allowed value (NUMERIC (22, 5))
2)then I insert 12345678901234567.1234 (17 digit before decimal point and 4 digit after decimal point and it didn't accept 5 digit after decimal point) and click apply button.
It insert the value as 12345678901234600 (value changed after Apply)
The I tried with simple SQL insert statement to insert data and it successfully insert 12345678901234567.12345 value.
Any item property I missed here to set?
Please suggest.
Thanks & Regards,

hi
according to
" then I insert 12345678901234567.1234 (17 digit before decimal point and 4 digit after decimal point and it didn't accept 5 digit after decimal point) and click apply button.
It insert the value as 12345678901234600 (value changed after Apply)"
this statement ,it seems that it is definitely applying round or somthing like that function in the code before inserting value in the table("try with select round(12345678901234567.1234 ) from dual u will get the same result = 123456789012345600 ") ,
bcz u r able to insert the same directely into the table using insert statement so kindely have look on the code if something like this is not happening there.try to check code in related EOimpl class
try to to use debugging mode ,and the 23 char problem is related to maximum lenghth of text box make it 23 it will get resolved and u will be able to enter 17 digits with 5 digits after decimal point
thanx pratap
