One parameter - multiple data types?

I posted a question similar to this in my attempts to use a lexical parameter to make my ORDER BY clause dynamic, but here's a more basic version of my question.
Is there a way to order by a column from the SELECT list, and make that column capable of having more than one different data type?
I'm trying to make my ORDER BY dynamic, but the data element the user chooses to order by may be a character, a number, or a date; however, I'm trying to use a parameter to do this, and Reports requires that a paremeter be designated as only one data type.
Anyone ever found a way to make their ORDER BY dynamic enough to accommodate for the possibility of ordering by just one column that may not always have a value of the same data type?

I think i have a solution for you at last.
Do...
Delare 2 user parameters.
MYPARAMETER1;
MYPARAMETER2;
In myparameter1. add values of your order by clause.
like.
COMMENT_DATE ASC
COMMENT_DATE DESC
AMOUNT ASC
AMOUNT DESC
etc
Let your myparameter2 empty & also do not diplay that on your parameter form.
Now open After Parameter Form Trigger under Report Triggers.
Code it as.
:MYPARAMETER2 := ' ORDER BY ' || ' ' || :MYPARAMETER1 ;
RETURN TRUE;
Then in your query in the end type
&myparameter2;
Hope this will work for u brice...

Custom components that accept multiple data types

The components that come with Flex, such as Datagrid, can
accept
multiple data types as a data source. For instance, you can
bind a
Datagrid to XML return from an HTTPService request or you can
build an
array and bind to that. I'd like to build my own component
that does
something similar, but I can't find any examples of this. I
don't
really even know what terms I'd search under to find it.
Can anyone out there give me any idea of how this is done?
Also, I'm a
bit hazy on how the column definitions you set up in the MXML
tag get
received inside the class. I'd appreciate any insight on how
this
works.
Thanks;

OK, I have looked at the source file, and it looks like the
[DefaultProperty] metatdata tag is at least not used in the
ListBase.as

ODI 10g Load table havfing XMLTYPE as one of the data type

I'm trying load data from source to target(Both Oracle) same table. The table has XMLTYPE as one of the data type. I can load the data, if I exclude that one particular column.
Is there any way to load the data from that XMLTYPE column as well? Please provide your input.
Source and traget has the same table structure.
Version: ODI 10G
below is the sample table structure.
CREATE TABLE APPLICATION
APPLID VARCHAR2(20 BYTE) NOT NULL,
JOBTYPE VARCHAR2(20 BYTE),
USRID VARCHAR2(20 BYTE) NOT NULL,
APPDOC SYS.XMLTYPE,
APPLSTATUS VARCHAR2(30 BYTE),
APPLDATE DATE
Thanks

Hi Pankaj,
Remember that 1 character is not equal to 1 byte anymore while numbers/hexadecimals are still.
So, if you have structures that are a mixture of characters and integers/hexadecimals etc, you can not move data from structure to structure as easily as before.
In code you mentioned:
LOOP AT L_TAB INTO L_REC.
APPEND L_REC TO LIST_TAB.
ENDLOOP.
Avoid moving directly from L_REC to LIST_TAB. You can try to define a work area (WA_TAB) for LIST_TAB and use a MOVE-CORRESPONDING from L_REC to the WA_TAB. Then append WA_TAB.
If the field names from L_REC do not match the field names in LIST_TAB, you can manually move each field value to the correct field in the work area.
Reward points if this solves your issue

SharePoint 2013 List - Multiple Data Types in the Same List

In the same SharePoint 2013 list in Data Sheet View, I want to have one column where my end users enter inputs for KPIs. There are 3 groups of KPIs (A, B and C) and they each have different data types (A-string, B-decimal, C-percentage) and I want to be
able to base their input options off of the KPI type
Does anyone have any suggestions on how I can leverage my parent-child relationships so when an end user...
1. Picks KPI type A, they can select from a choice filed (Green, Yellow, Red)
2. Picks KPI Type B, they can enter a decimal (-1.000 to 2.000)
3. Picks KPI Type C, they can enter a percentage (-100.00% to 100.00%
I'm using if I want to keep this in one list, one column and in data sheet view that the out of the box solutions won't meet my requirements. I was looking at some solutions from Bamboo (Lookup Selector Column) but don't think that applies here.
Thanks!

Hi Johnny, you can accomplish this using cascading lookups in InfoPath if that program is available to you. Otherwise, if you want a 3rd party product, we use the Kwiz cascading lookup and it's worked wonders for us:

Note: I have no relationship with Kwiz, just vouching for the product.

Switch datetime type parameter to date type

Hello expert,
I created crystal report by oracle procedure directly , but a date parameter for this procedure is mapped to datatime type parameter in crystal report, its format is dd/mm/yyyy hh:mm:ss. instead of this datatime format, I need date format as "dd/mm/yyyy", but I found I can't change data type for this procedure parameter in crystal report. I know I can't choose data type for procedure parameter if I use procedure in command. but over here, I have to use this procedure directly instead of using command as data connection for this report. Can I change this procedure parameter for datetime type to date type in the crystal report. Apprecaite very much.

You can get crystal to treat the datetime field as a date field by addressing it as
date({datetime})
when ever you refer to it. You may even be able to address your parameter as
date({?datetimeparameter})

Generic sort algorithim multiple data types

How would I create a method to sort any type of data type given.
Would I have to overload the method and rewrite the algorithim for each data type. This seems redundant. Could I use an interface somehow. I am clueless. I know you can do this in c++ using templates. How do you do it in Java?

you can use the standard API for ideas.
to sort objects you need to know which should come before others, and how to put them in order.
the standard api has two ways to solve the first part: the interface java.lang.Comparable which is implemented by objects that are, well, comparable, and the interface java.util.Comparator that can compare two arbitrary objects.
the second part is solved by implementing a method like Arrays.sort.

One Parameter, 2 data sources.

I have a report that is running of a parameter in MDX. The parameter is Company Name.
i have just added a dataset to the report that is coming from a stored procedure in SQL. The stored procedure passes a parameter company_code.
How can i run this report so that it just uses the same parameter.

Hi Irj1985,
In your scenario, there are two parameters Comapny_Name and Company_Code for two datasets in your report, now what you want is that use just one parameter on the report, right?
In this case, you can create another dataset to get company name base on company code use the query like:
SELECT Company_Name FROM TABLE WHERE Company_Code=@Company_Code
And then set the Company_Name parameter get available value and default value from this dataset Company_Name column, and hide this parameter.
Then when you run the report, you just need pick one parameter Company_Code, it looks like you just use one parameter on your report.
If I have anything misunderstood, please point it out.

Sw engineering question - multiple data types

hi all
Im in a situation where I will have to read in data that could come in many formats, int, double, float, etc...
The question is how do I create a "datastorage" class that has a "getdata" method that doesnt care about the type of the data it is returning? I am trying to avoid a situation where somewhere along the line someone has to write an if(int) do this and if(float) do that, but it might not be avoidable...comments on that are welcome too...
two ideas floating around in my head are
1) declare an abstract DS class and then have intDataStorage, doubleDatastorage, etc
2) have on DS class that stores the data in Arrays of Integer, Double, etc
neither of these ideas leads to a way of avoiding if statements to determine the datatype however...
thanx in advance

If it's all number types, then they could all be stored as a double, except maybe some extreme long values. Or strings, but you'd still have to parse them and still use ifs
But most "formats" usually define things like the "format" of what the data will look like.

One Parameter, multiple Conditions - Old version of Disco?

Hi,
I have a report where I want to base a number of conditions on a single parameter. The version of Disco I am using doesn't seem to allow me to do this. There is no 'select parameter' option.
Disco Desktop version is: 4.1.47.09.00 - old!!!
Seems like a very simple bit of functionality. Is this possible? If so how do I go about it.
Cheers,
Jon.

Hi,
Try to create the parameter without basing it on an item (chose the <None>).
I think that you don't have the option since you based your parameter on a specific item so that it cannot relate to other items in the conditions.

Passing one parameter to multiple views

Is this possible? I would like to pass one parameter, a date field, to multiple views. I cannot use it in the record selection, because my views do a mathematical computation which returns a single value, but I only want to select the data for a single day.
The problem is that there are several views and I do not want to have to enter the date parameter a dozen times.

Try to use add command and write the query like this
select * from view where datefield={?date}
also create another add command for the other view
select * from view2 where datefield2={?date}
for all the queries create the same parameter with the name {?date}

A structure with mutiple data types or array of array

I want to read some soft of a table from a text file and want to store in a structure (not in database) for future use. I want the structure to have rows and columns when I need to reach. Colums should store multiple data types (int and/or string). I have examined Collections that only store one data type and only one dimension. I need a structure that holds multiple datatypes and at least 2 dimension. In short I need array of array? Any example or suggestion?

Unicode and non-unicode string data types Issue with 2008 SSIS Package

Hi All,
I am converting a 2005 SSIS Package to 2008. I have a task which has SQL Server as the source and Oracle as the destination. I copy the data from a SQL server view with a field nvarchar(10) to a field of a oracle table varchar(10). The package executes fine
on my local when i use the data transformation task to convert to DT_STR. But when I deploy the dtsx file on the server and try to run from an SQL Job Agent it gives me the unicode and non-unicode string data types error for the field. I have checked the registry
settings and its the same in my local and the server. Tried both the data conversion task and Derived Column task but with no luck. Pls suggest me what changes are required in my package to run it from the SQL Agent Job.
Thanks.

What is Unicode and non Unicode data formats
Unicode :
A Unicode character takes more bytes to store the data in the database. As we all know, many global industries wants to increase their business worldwide and grow at the same time, they would want to widen their business by providing
services to the customers worldwide by supporting different languages like Chinese, Japanese, Korean and Arabic. Many websites these days are supporting international languages to do their business and to attract more and more customers and that makes life
easier for both the parties.
To store the customer data into the database the database must support a mechanism to store the international characters, storing these characters is not easy, and many database vendors have to revised their strategies and come
up with new mechanisms to support or to store these international characters in the database. Some of the big vendors like Oracle, Microsoft, IBM and other database vendors started providing the international character support so that the data can be stored
and retrieved accordingly to avoid any hiccups while doing business with the international customers.
The difference in storing character data between Unicode and non-Unicode depends on whether non-Unicode data is stored by using double-byte character sets. All non-East Asian languages and the Thai language store non-Unicode characters
in single bytes. Therefore, storing these languages as Unicode uses two times the space that is used specifying a non-Unicode code page. On the other hand, the non-Unicode code pages of many other Asian languages specify character storage in double-byte character
sets (DBCS). Therefore, for these languages, there is almost no difference in storage between non-Unicode and Unicode.
Encoding Formats:
Some of the common encoding formats for Unicode are UCS-2, UTF-8, UTF-16, UTF-32 have been made available by database vendors to their customers. For SQL Server 7.0 and higher versions Microsoft uses the encoding format UCS-2 to store the UTF-8 data. Under
this mechanism, all Unicode characters are stored by using 2 bytes.
Unicode data can be encoded in many different ways. UCS-2 and UTF-8 are two common ways to store bit patterns that represent Unicode characters. Microsoft Windows NT, SQL Server, Java, COM, and the SQL Server ODBC driver and OLEDB
provider all internally represent Unicode data as UCS-2.
The options for using SQL Server 7.0 or SQL Server 2000 as a backend server for an application that sends and receives Unicode data that is encoded as UTF-8 include:
For example, if your business is using a website supporting ASP pages, then this is what happens:
If your application uses Active Server Pages (ASP) and you are using Internet Information Server (IIS) 5.0 and Microsoft Windows 2000, you can add "<% Session.Codepage=65001 %>" to your server-side ASP script.
This instructs IIS to convert all dynamically generated strings (example: Response.Write) from UCS-2 to UTF-8 automatically before sending them to the client.
If you do not want to enable sessions, you can alternatively use the server-side directive "<%@ CodePage=65001 %>".
Any UTF-8 data sent from the client to the server via GET or POST is also converted to UCS-2 automatically. The Session.Codepage property is the recommended method to handle UTF-8 data within a web application. This Codepage
setting is not available on IIS 4.0 and Windows NT 4.0.
Sorting and other operations :
The effect of Unicode data on performance is complicated by a variety of factors that include the following:
1. The difference between Unicode sorting rules and non-Unicode sorting rules
2. The difference between sorting double-byte and single-byte characters
3. Code page conversion between client and server
Performing operations like >, <, ORDER BY are resource intensive and will be difficult to get correct results if the codepage conversion between client and server is not available.
Sorting lots of Unicode data can be slower than non-Unicode data, because the data is stored in double bytes. On the other hand, sorting Asian characters in Unicode is faster than sorting Asian DBCS data in a specific code page,
because DBCS data is actually a mixture of single-byte and double-byte widths, while Unicode characters are fixed-width.
Non-Unicode :
Non Unicode is exactly opposite to Unicode. Using non Unicode it is easy to store languages like ‘English’ but not other Asian languages that need more bits to store correctly otherwise truncation will occur.
Now, let’s see some of the advantages of not storing the data in Unicode format:
1. It takes less space to store the data in the database hence we will save lot of hard disk space.
2. Moving of database files from one server to other takes less time.
3. Backup and restore of the database makes huge impact and it is good for DBA’s that it takes less time
Non-Unicode vs. Unicode Data Types: Comparison Chart
The primary difference between unicode and non-Unicode data types is the ability of Unicode to easily handle the storage of foreign language characters which also requires more storage space.
Non-Unicode
Unicode
(char, varchar, text)
(nchar, nvarchar, ntext)
Stores data in fixed or variable length
Same as non-Unicode
char: data is padded with blanks to fill the field size. For example, if a char(10) field contains 5 characters the system will pad it with 5 blanks
nchar: same as char
varchar: stores actual value and does not pad with blanks
nvarchar: same as varchar
requires 1 byte of storage
requires 2 bytes of storage
char and varchar: can store up to 8000 characters
nchar and nvarchar: can store up to 4000 characters
Best suited for US English: "One problem with data types that use 1 byte to encode each character is that the data type can only represent 256 different characters. This forces multiple
encoding specifications (or code pages) for different alphabets such as European alphabets, which are relatively small. It is also impossible to handle systems such as the Japanese Kanji or Korean Hangul alphabets that have thousands of characters."<sup>1</sup>
Best suited for systems that need to support at least one foreign language: "The Unicode specification defines a single encoding scheme for most characters widely used in businesses around the world.
All computers consistently translate the bit patterns in Unicode data into characters using the single Unicode specification. This ensures that the same bit pattern is always converted to the same character on all computers. Data can be freely transferred
from one database or computer to another without concern that the receiving system will translate the bit patterns into characters incorrectly.

How can I calling LabView DLL within LabView and pass similar Data Types?

I am trying to use an Instrument Driver, which is created in LabView6.1 as a DLL. At this point I have only LabView to test this DLL. I was wondering, is there easy way to find out what sort of Parameter or Data Type I should be using.
How can I pass the following data with in LabView:
LVRefnum as Type?
LVBoolean as Type?
TD1 (a structure) as Type?
It is funny to see that I am able to create a DLL in labview but having trouble calling it within LabView. I thought, it would be easier to test the DLL within the same environment.
Basically, I am more worried about the VISA calls that are used in the driver to communicate with instrument. Because, there is no link to �VISA32.dll� in
the header file, is that handled by the LV Run-time engine? I guess more details are needed on using the LabView DLL within LabView from National Instrument Technical Support.

RL5000.h ‏1 KB

A LVRefNum seems to be an unsigned long data type (32bit). You can cast it
in LV then use that as a parameter to call the DLL. (an Occurrence type
seems to be a Ulong32)
When you created the DLL what was the resulting type for the LVRefNum?

Multiple Display Types in a single column

I have a situation where I have to display a bunch of attributes for a customer. Each attribute can have a different type, Text, Dropdown, Date etc and that information is stored in a table.
I was able to use apex_item to display the different display types based on the type of attribute.
So the layout of the form has 2 columns, column 1 is the name of the attribute and column 2 is the value of the attribute (displayed as the various types of date, text, dropdown etc) However, I am having an issue with the Date popups. When I select a date it always goes into whatever date is listed first. No sorting is going on in the select or the report.
I'm guessing my issue has to do with displaying different display types in the same column? If that is true, how should I change my approach to this problem? I want all the attributes on a single page, so is my only option to have each attribute in a different region?
Thanks,
-- Johnnie

Denes,
OK thanks for the heads up, let me try to clarify.
My problem is that I have multiple date popups on the same form. When I pick a date for any of the date popups, it always updates the first date popup field on the form. I stated there was no sorting at all because this thread indicated that sorting could cause this issue:
DATE_POPUP
Another hit for this issue was here:
Re: HTMLDB_ITME.DATE_POPUP problems
This suggested that having multiple data types in the same column (which is what I am doing) is not supported, but this is an old thread.
My form will be a manual tabular form. I need to display a list of attributes, however some are freeform text, some are SQL LOV dropdowns, and some are date popups. Right now they are all displayed in the same column. Could this be causing my date popup issue? If so what alternatives do I have?
Screenshot of my form here: http://johnniebillings.googlepages.com/outlook.jpg
Hope that clears up the issue I am having.

Data Type for Process Flow... PB with Date?

I've got a problem by passing parameters in process flow.
I have a mapping with a parameter DATE_EXEC (data type : DATE) and a default value that is TO_DATE('20/01/2007' , 'dd/mm/yyyy') . My mapping is working good when i launch it.
I have a process flow which contains the mapping. This process has a parameter DATE_EXEC (data type : DATE). I bind the 2 DATE_EXEC. But when i launch my mapping the value is not recognized, I try with :
- TO_DATE('20/01/2007' , 'dd/mm/yyyy')
- 20/01/2007
- 2007.01.20
- 2007-01-20
My question is what are the data type in process flow? They are not ORACLE TYPE.
For example , a parameter in a mapping which is a VARCHAR2 must be input between quotes but if you bind it to a parameter of a process flow which is a STRING (not ORACLE Data type) , you must input it without quotes?
Anybody has some rules about that?
I apologize for my english, i'm a french people.

Here is some information on the literal quote or not quote query and what I think you need to do at the end, hope it helps. Not exactly intuitive...since the flow designer (you) have to know what is a PLSQL object and what is not.
1. Literal = FALSE
When Literal = FALSE is set then the value entered must be a valid PL/SQL expression which is evaluated at the Control Center e.g.
'Hello World!'
22 / 7
2. Literal = TRUE
When Literal = TRUE then the value is dependent on the the type of Activity. If the activity is a PL/SQL object i.e. Mapping or Transformation, then the value is PL/SQL snippet. The critical difference here is that the value is macro substituted into the call for the object. The format of the value is identical to that entered as default value in the Mapping editor. e.g.
'Hello World!'
sysdate()
If the activity type is not a PL/SQL object then the value is language independent. e.g.
Hello World
3.1427571
What you should try......
Check the map activity parameter in your process flow to see if literal is false (an expression), set it to false and then try using your TO_DATE('20/01/2007' , 'dd/mm/yyyy') expression, deploy your flow and execute. Alternatively the user guide defines the DATE type for flow with the format YYYY-MM-DD so you can have the parameter value as '2007-01-20' use literal equal to true and remember and quote your value.

One parameter - multiple data types?
