How to supress Zero in NUMC data type which contains some values as Char.

Hello Friends,
Some custom fields have been added in table BUT000 ,
out of which one field has data type as NUMC..
When i see some of the entries in the that field, it has values like '0000000000000000ENT'.
I want to supress Leading zeros of that.
i tried using
1 ) FM CONVERSION_EXIT_ALPHA_OUTPUT &
          CONVERSION_EXIT_ALPHA_INPUT .
2 ) Also tried coding like this:
data:var1 type ZBU_00LV36AT,           "this field has data type NUMC of length 40
       var2(40) type N.
var1 ='00000000ENTRY'.
VAR2 = VAR1.
SHIFT VAR2 LEFT DELETING LEADING '0'.
Nothing works ...gives output as blank.
Is there any solution for it....
Any valuable asnwer will be rewarded...

Mayank

Hi Marcin,
I have tried i think problem it solved with your solution.
Let me try for some more cases if it works fine i will get back to forum.

Supressing 0 in NUMC data types

Hello,
I am trying to suppress leading zeros in a numc data type. I use the value in a BDC , and it then stores the leading zeros.
Thanks

USE FMs
CONVERSION_EXIT_ALPHA_INPUT OR
CONVERSION_EXIT_ALPHA_OUTPUT
to supress leading zeros.

Truncate leasding zeros of NUmc data type

i want to download the value po item no which is of
length 10 of data type numc
number_int(10) type Numc in the data base.
in the output the value displayed for the line item
one is 0000000001
But i want to get only the value 1 . leading zeros should
be truncated.
I tried using condense and write to by using a temporaray
va_poitemno type char10.
its not working
Please suggest to do this .
How to do that

Hi,
Either we can do it by Coding or using Function module:
DATA : i(10) TYPE n VALUE 0000000001.
SHIFT i LEFT DELETING LEADING '0'.
Or
DATA: matnr type mara-matnr value '000000000000000068',
          lv_matnr type mara-matnr.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
EXPORTING
    input             =   matnr
IMPORTING
   OUTPUT        =   lv_matnr
WRITE: lv_matnr.
This will surely work.
Plz reward if useful.

New Effective CAL essay: How do I create an abstract data type in CAL?

How do I create an abstract data type in CAL? An abstract data type is one whose internal representation can be changed without needing to modify the source code of client modules that make use of that type. For software maintainability, it is a good idea to make a type that is subject to change or enhancement into an abstract data type. Another reason to create an abstract data type is to enforce invariants for values of the type that can only be ensured by using constructor functions (i.e. functions that return values of that type). In principle it is simple to create an abstract data type in CAL. For an algebraic data type, make the type constructor public and all data constructors private. For a foreign data type, make the type constructor public and the implementation scope private. If a scope qualifier is omitted, the scope is taken to be private. For example, the Map algebraic data type has the public type constructor Map and the data constructors Tip and Bin are each private, so it is an abstract data type. /** A map from keys (of type {@code k@}) to values (of type {@code a@}). */ data public Map k a = private Tip | private Bin size :: !Int key :: !k value :: a leftMap :: !(Map k a) rightMap :: !(Map k a); There are a number of invariants of this type: the size field represents the number of elements in the map represented by its Bin value. The keys in leftMap are all less than key, which in turn is less than all the keys in rightMap. In particular, non-empty Map values can only be created if the key parameter type is a member of the Ord type class. Values of the Map type can be created outside the Cal.Collections.Map module only by using constructor functions such as insert: insert :: Ord k => k -> a -> Map k a -> Map k a; public insert !key value !map = ... The owner of the Cal.Collections.Map module must ensure that all invariants of the Map type are satisfied, but if this is done, then it will automatically hold for clients using this function. Some examples of foreign abstract data types are Color, StringNoCase and RelativeDate: data foreign unsafe import jvm private "java.awt.Color" public Color; data foreign unsafe import jvm private "java.lang.String" public StringNoCase; data foreign unsafe import jvm private "int" public RelativeDate; The private implementation scope for Color means that a foreign function whose type involves Color can only be declared in the Cal.Graphics.Color module where the Color type is defined. A foreign function declaration involving the Color type relies on the compiler knowing that the Color type corresponds to java.awt.Color to resolve the corresponding Java entity i.e. it must know about the implementation of the Color type. Having a private implementation scope means that the Color type can be changed to correspond to a different Java class, or indeed to be an algebraic type, without the risk of breaking client code. In all these three cases there are useful, and different, design reasons to adopt a private implementation scope: For RelativeDate, the Java implementation type int represents a coded Gregorian date value in the date scheme used by Crystal Reports. Not all int values correspond to valid dates, and the algorithm to map an int to a year/month/day equivalent is fairly complicated, taking into account things like Gregorian calendar reform. Thus, it is desirable to hide the implementation of this type. For StringNoCase, the implementation is more straightforward as a java.lang.String. The reason to adopt a private implementation scope is to ensure that all functions involving StringNoCase preserve the semantics of StringNoCase as representing a case-insensitive string value. Otherwise it is very easy for clients to declare a function such as: foreign unsafe import jvm "method replace" replaceChar :: StringNoCase -> Char -> Char -> StringNoCase; which does not handle case-insensitivity correctly, but is a perfectly valid declaration. This declaration results in a compilation error when it is placed outside the module in which StringNoCase is defined because of the private implementation scope of StringNoCase. For Color, the issue is somewhat more subtle. The java.awt.Color implementation type is semantically the same as the CAL Color type. The problem is that java.awt.Color is mutable (since it can be sub-classed to create a mutable type). It is preferable for a first-class CAL type to not be mutable, so we simply make the implementation scope private to ensure that this will be the case. A somewhat less encapsulated kind of abstract data type can be created using friend modules and protected scope. For example, if an algebraic type is public, and all its data constructors are protected, then the data constructors can be accessed in the friend modules of the module in which the type is defined. Effectively this means that the implementation of the semantics of the type stretches over the module in which the type is defined, and all of its friend modules. These must all be checked if the implementation of the type is modified. Given the merits of abstract data types discussed above, it is perhaps surprising that most of the core types defined in the Prelude module are not abstract data types. For example: Boolean, Char, Int, Double, String, List, Maybe, Either, Ordering, JObject, JList, and all record and tuple types are non-abstract types. There are different reasons for this, depending on the particular type involved. For example, Boolean, List, Maybe, Either and Ordering are all rather canonical algebraic data types with a long history in functional languages, with many standard functions using them. They are thus guaranteed never to change. In addition, their values have no particular design invariants that need to be enforced via constructor functions. Exposing the data constructors gives clients some additional syntactic flexibility in using values of the type. For example, they can pattern match on the values using case expressions or let patterns. Essentially the same explanation holds for record and tuple types. Although non-tuple record types are less canonical, they do correspond to the fundamental notion of an anonymous named-field product type. The "anonymous" here simply means that the programmer can create an entirely new record type simply by creating a value; the type does not have to be declared anywhere prior to use. Char, Int, Double, String, JObject and JList are foreign types where in fact part of the semantics of the type is that we want clients to know that the type is a foreign type. For example, we want clients to know that Prelude.Int is essentially the Java primitive unboxed int type, and has all the semantics you would expect of the Java int type i.e. this is quite different from RelativeDate which is using int as its implementation type in a very tactical way that we may choose to change. One can think of a public foreign type declaration with public implementation scope as simply introducing the Java type into the CAL namespace. One interesting point here is with CAL's naming convention for public foreign types. We prefix a type name by "J" (for "Java") for foreign types with public implementation type such that the underlying Java type is mutable. This is intended as mnemonic that the type is not a pure functional type and thus some caution needs to be taken when using it. For example, Prelude.JObject has public Java implementation type java.lang.Object. In the case where the underlying Java type is not mutable, we do not use the prefix, since even though the type is foreign; it is basically a first class functional type and can be freely used without concern. For example, Prelude.String has public Java implementation type java.lang.String. In the case where the implementation type is private, then the fact that the type is a foreign type, whether mutable or not, is an implementation detail and we do not hint at that detail via the name. Thus Color.Color has as its private Java implementation type the mutable Java type java.awt.Color. When creating abstract data types it is important to not inadvertently supply public API functions that conflict with the desired public semantics of the type. For example, if the type is publicly a pure-functional (i.e. immutable) type such as Color, it is important not to expose functions that mutate the internal Java representation. A more subtle case of inadvertently exposing the implementation of a type can occur with derived instances. For example, deriving the Prelude.Outputable and Prelude.Inputable type classes on a foreign type, whose implementation type is a mutable Java reference type, allows the client to gain access to the underlying Java value and mutate it
(by calling Prelude.output, mutating, and then calling Prelude.input). The solution in this case is to not derive Inputable and Outputable instances, but rather to define a custom Inputable and Outputable instance that copies the underlying values.

How to create longtext or blob data types in SQL using labview

Hello,
I am fairly new to SQL, and I'm using the labview database connectivity toolset. Using labview 6.1
I am using the DB Tools Create Table vi to create my tables. I want the tables to hold 1000 character strings. But the longest string that I can insert seem to be 255 characters. I think It is a limitation of the "String" data type in SQL so I need to use text or blob types. The problem is I created a control for the "Column Information" field and I see the following selections for the data type. (String, Long, Single, Double, date/time, binary). I dont see any selection for text or blobs. How do I define another data type that is not part of the selection in the control?
Thanks for any help.

I don't know about defining long text, but the equivalent of a BLOB should be the binary data type, which just holds the data you put into it without formatting it.
Try to take over the world!

How to dynamic set messageInputText item data type?

Hi,
I have a LOV and other messageInputText items on the page. I need to be able to change the messageInputText item data type based on the value selected from LOV. How can I do that?
DD

1)Allow PPR on the item that receives the LOV values
2)Edit the VO query and create a SQL based column, which in turn will control the switcher. Something like –
decode(nvl(to_char(EmployeeEO.END_DATE), 'N'), 'N', 'DataType1', 'DataType2') AS DELETE_SWITCHER
3)Now add a switcher region with two cases in your page. Each case should represent the two possible values defined in the SQL based column ( “DataType1”, DataType2” in the above example).
4)Add two messageTextInput items under each case, but with different datatypes.

How to replace content in text data type?

How to replace content in text data type?
when we sending the mails we are taking content from the database.
The data is maintained in text data type column. Now i have to replace some of content in mail content
(text data type column) from database.
I tried by using REPLACE function but data is truncated

The data is maintained in text data type column.
Hello,
See REPLACE (Transact-SQL) => "If
string_expression is not of type varchar(max) or
nvarchar(max), REPLACE
truncates the return value at 8,000 Bytes"
You may should consider to Change the data type from "Text" (deprecated) to NVarChar(max).
Otherwise you have to use
UPDATETEXT (Transact-SQL) for the text data type.

Can "SPML Web Service Complex Data Type field" take multiple values ?

In Generic Technology Connector's -SPML design parameters section, Can we give multiple values in SPML Web Service Complex Data Type field?
If not, how can i call methods directly instead of calling them through a values of the "name" attribute of the "complexType" element in SPML Web Service Complex Data Type?
I need 'SPML Web Service Complex Data Type' to hold multiple values.And based on the request it has to initiate appropriate method of action.
Presently i have three methods add,modify and delete which i am calling through a single value of the "name" attribute of the "complexType" element in SPML Web Service Complex Data Type.
I want to replace this single value with multiple menthods , so that a direct interaction between the method,OIM and target can be established.

You'll need to create your own interface to the webapp database for those kind of data operations
by this, are you speaking of the internal BC database which stores web app schema data? That would be great if it were possible to update that programmatically because I need to use the List (Checkbox List) field type (for the search functionality), but I need to supply the checkbox options from a web app rather than by manually updating the list entered in the Fields view of the web app settings (shown below).
I'm curious if anyone else has tried this?
Again, my reason for needing to use the List (Checkbox List) field type is that the page which processes searches knows to expect a comma separated list for this field type and then appears to be parsing out the individual values for searching out web app items with 1 or more matching values. You're right that text fields (string and multiline) just check for 'string contains' matches, and this would be ok if I was only ever needing to search just one value at a time. Here's an example of what I might do:
Web App item field value (as recorded against the List (Checkbox List) field type:
8294877,8294878
Web App Search value (for this same field):
8294879,8294877,8294885
The search would return this web app item because the field contains 2 (1 or more) individual values even though they were entered into the search field in a different order. If this web app item were just a Text (string or multiline) field, the searched value is not a substring of the web app item's stored value, so it would not find a match. Hence the need to use Checkbox List field type.
The web app will have thousands if not 10s of thousands of records, so dumping them all into one big array or object and searching on the front-end won't be practical (though it works great on smaller datasets).

How can i join more than 20 tables which contains more than 5 lacks records

how can i join more than 20 tables which contains more than 5 lacks records

If you're trying to join 20 tables I would check:
- Are all the joins necessary. It's easy sometimes to just join to another table because you're unsure as to whether it's required.
- What sort of application is it? 20 joins seems a lot to me. Are you trying to achieve too much with one query? Is it possible to break the problem down?
- If it is necessary to join so many tables then force the use of hash joins in the query, especially if you're processing a lot of data and want the best throughput. If you want a quicker response, this will not be a appropriate.
