How to compare value in input field to value in database?

Hi all. I need to clear up if the value in the input field (e.g. input_field) is equal to at least one record in the field (e.g. name) in database table (e.g. customers), or not. The code should be like this:
IF...
message001. "(there's such a record in database)
ELSEIF...
message002. "(there's no such record in database)
ENDIF.
thanks all.

Hi,
I think u r asking about validating the selction screen and displaying a mess if that input is not in the DB right?
AT SELECTION-SCREEN ON s_matnr.
*Validate material no details
PERFORM validate_matno.
FORM validate_matno.
SELECT SINGLE matnr INTO v_matnr
         FROM mara
         WHERE matnr IN s_matnr.
IF sy-subrc NE 0.
    MESSAGE i128.
    LEAVE LIST-PROCESSING.
ENDIF.
ENDFORM.
Make sure that u are validating against the header table.
say eg if u wnat t validate matnr in marc, then do as below.
SELECT-OPTIONS: s_matnr FOR marc-matnr.                  "Material No
AT SELECTION-SCREEN ON s_matnr.
*Validate material no details
PERFORM validate_matno.
FORM validate_matno.
DATA: v_matnr LIEK mara-matnr.
SELECT SINGLE matnr INTO v_matnr
         FROM <b>mara</b>
         WHERE matnr IN s_matnr.
IF sy-subrc NE 0.
    MESSAGE i128.
    LEAVE LIST-PROCESSING.
ENDIF.
ENDFORM.
Dont select from marc.
Hope this is clear.

How to compare values in table control

Hi Experts,
How to compare two values of a field in table control. Like the frist row of feld1 with the second row of field1.
because when ever two values are same i need to display error message that we are entring duplicate entry.
i have been tring for a very log time but not getting any solution for this.
Thanks and Regards,
Ashwin.

you need to write in code for this..
A possible solution is given below..
Suppose your internal table fields are col1 and col2.
in the loop .....endloop of yout internal table in your PAI..there will be following(if your table control is made using wizard. otherwise you might have to add it..
loop at itab.
chain.
field col1.
field col2.
"some module
endchain.
endloop.
now make changes as shown to the above code..
loop at itab.
chain.
field wa-col1.
field wa-col2.
module table_modify on chain-request.
endchain.
now in your program add module table modify.
module table_modify input.
read table itab with key col1(which shud be unique) = wa-col1 transporting no-fields.
if sy-subrc = 0. " there exists another record with the same value
message e001(your message class).
endif.
endmodule.
i guess that shud work. get back if it dosnt.

How to set Date in input field by hard coding in application

Hi all,
1.I have to make a date(its my choice to set the date) to appear in input field which is date type.
2.How to compare two numbers of type decimal. for example greatest of two numbers
urgent requirement

Hi
Check the http://java.sun.com/j2se/1.4.2/docs/api/java/sql/Date.html
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Calendar.html
Sample Code
Date now = new Date();
      DateFormat df = DateFormat.getDateInstance();
      String s = df.format(now);
      System.out.println("Today is " + s);
java.sql.Date descends from java.util.Date, but uses only the year, month and day values. There are two methods to create a Date object. The first uses a Calendar object, setting the year, month and day portions to the desired values. The hour, minute, second and millisecond values must be set to zero. At that point, Calendar.getTime().getTime() is invoked to get the java.util.Date milliseconds. That value is then passed to a java.sql.Date constructor:
    Calendar cal = Calendar.getInstance();
    // set Date portion to January 1, 1970
    cal.set( cal.YEAR, 1970 );
    cal.set( cal.MONTH, cal.JANUARY );
    cal.set( cal.DATE, 1 );
    cal.set( cal.HOUR_OF_DAY, 0 );
    cal.set( cal.MINUTE, 0 );
    cal.set( cal.SECOND, 0 );
    cal.set( cal.MILLISECOND, 0 );
    java.sql.Date jsqlD =
       new java.sql.Date( cal.getTime().getTime() );
The second method is java.sql.Date's valueOf method. valueOf() accepts a String, which must be the date in JDBC time escape format - "yyyy-mm-dd". For example,
    java.sql.Date jsqlD = java.sql.Date.valueOf( "2010-01-31" );
creates a Date object representing January 31, 2010. To use this method with a Calendar object, use:
    java.sql.Date jsqlD = java.sql.Date.valueOf(
            cal.get(cal.YEAR) + ":" +
            cal.get(cal.MONTH) + ":" +
            cal.get(cal.DATE) );
which produces a Date object with the same value as the first example.

How to compare values in resultset

i am having problem in comparing result set values. Actually my store proc returns me the following resultset:
Month | Year | Deductible | Troop | TDC | ReasonCode
------------|-----------|-----------------|------------|-------------|--------------------------
January | 2008 | $100.0 | $0.0 | $0.0 | 1
------------|-----------|-----------------|------------|--------------|--------------------------
January | 2008 | $0.0 | $10.0 | $0.0 | 1
------------|-----------|---------------- |-------------|-------------|-------------------------
January | 2008 | $0.0 | $0.0 | $20.0 | 1
------------|-----------|-----------------|-------------|-------------|-------------------------
March | 2008 | $150.0 | $0.0 | $0.0 | 2
------------|-----------|-----------------|-------------|-------------|--------------------------
March | 2008 | $0.0 | $15.0 | $0.0 | 2
------------|-----------|-----------------|-------------|-------------|-------------------------
March | 2008 | $0.0 | $0.0 | $30.0 | 2
i will compare month and year fields. i.e if year is same the compare month and if month is same (e.g. January) the first three row of the above table will be clubbed in one row i.e.
Month | Year | Deductible | Troop | TDC | ReasonCode
------------|-----------|-----------------|------------|--------------|--------------------------
January | 2008 | $100.0 | $10.0 | $20.0 | 1
how can i do it in my result set?

Learn SQL
"Select Month, Year, SUM(Deductible), SUM(Troop), SUM(TDC), ReasonCode from table Group By Month, Year, ReasonCode"Otherwise, loop through the resultset and compare the fields you want to compare using .equals() and sum the values yourself (of course).

How to do validation of input fields

Hi all,
I have a rquirement to do the validation of input fields.Can anybody explain me how to go for that???Please explain in detail.U can also give me a link where i can find the tutorial for doing this.

Hi Amit,
What everyone has said above is correct - in the method of your action simply test for whatever condition you need to validate for. However, the following tutorial shows you how to use Web Dynpro's Message Manager to display the messages on the screen in an easy user-friendly way:
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/wd%20java/wd%20tutorials/a%20simple%20input%20form%20with%20message%20and%20error%20service%20support.pdf">Enabling Message and Error Support</a>
In addition, there are some validations that are done automatically depending on what you have your input fields set to - for instance, if you bind your input field to a date and a user enters words into the field instead of an actual date, it will automatically display an error message. To learn how to turn this feature on and off, see this tutorial

Please Help. How to access to an input field in a table with javascript

Hi
i�m trying to access to the content of an input field that is in an table with a javascript function in this way
function Valida_Tabla()
var centro = document.getElementById("form1:idcentro").value;
alert("Centro es ["+centro+"]")
var des = document.getElementById("form1:table1:0:textField2").value;
alert("des ["+des+"]")
The fisrt alert is ok and displays the value of a field that is in a table.
The second alert is not displayed.
Is the syntax wrong?
what i�m doing wrong
Please help

The best bet is to look at the source of the generated HTML and then use the exactly generated ID in the HTML source. When I looked at the HTML source I see the ID of a textfied inside a table as
form1:table1:tableRowGroup1:0:tableColumn1:textField1

How to populate read only input field or text view form value help only

Hi experts,
I have one requirement to populate a read-only field or text view from value help.
User cant put any value there.value comes only from the value help.
For example,
when we read context using Code Wizard,we cant type any value there.value only comes from value help.
How to implement that functionality?
Please reply.
Thanks in advance,
Subhasis.

Yes it is possible.
1.Create a context Attribute and then bind this attribute to the Text view UI element.
2. read context attribute and then set value to the context attribute like this way.
DATA:
    elem_context1                        TYPE REF TO if_wd_context_element,
    stru_context1                        TYPE if_first=>element_context ,
    item_potxt                          LIKE stru_context-potxt.
get element via lead selection
elem_context1 = wd_context->get_element( ).
stru_context1-potxt = 'PO'.
elem_context1->set_attribute(
    VALUE = stru_context1
    name   = 'POTXT'

How to compare and copy the fields from repeating subform to another subform, same structure.

Dear All,
I am using LiveCycle Designer 8.2.
I have the following requirement, and did not figure out the best way to implement it using JavaScript.
The Form has, say, Subform A with Repeating Inner Subform, say it has the Education History of the Staff.
I want to put another Subform B, with similar structure to From A, and create a button/function to copy the field data values from A to B.
Subform A will show the user the fields of education with Read-Only Mode.
Subform B will show the user the same data values with write-enable mode. This subform will allow the user update his Education Records.
The fields are:
0. Staff ID: Text (Key 1) (always read-only and hidden, becuase it is on the main form),
1. Degree: Text,
2. Specialization: Text,
3. Institution: Text,
4. Start Date: Date (Key 2),
5. End Date: Date.
Another function is needed is to compare the same records between form A and Form B.
(Note: The Education record of a Staff has primary key of Staff ID and Start Date. Meaning, the Staff cannot have tow different degrees in starting on the same date.)
The user may change the Institution in form B or change the Degree. I need to highlight, on Subform B, the row which was changed or added by the user. This means I need to do lookup against Subform B using the Key Values from Subform A.
I have already developed the Form, and I have about 5 Subforms to allow updated by Staff: Education, Experience Inside the company, Experience Outside the company, Job Skills, Membership Record, ..etc. One thing I did is that the Field Names I used in Subform A are not the same of the fieldname in Subform B, but the have same suffix, and different prefix. For example, for the Education:
Subform A - Original Values:
1. Degree: OrgDegreet,
2. Specialization: OrgSpecialization,
3. Institution: OrgInistitution,
4. Start Date: OrgDateStart (Key),
5. End Date: OrgDateEnd.
Subform B - Updated Values:
1. Degree: UpdDegreet,
2. Specialization: UpdSpecialization,
3. Institution: UpdInistitution,
4. Start Date: UpdDateStart (Key),
5. End Date: UpdDateEnd.
I understand if the Key field is updated, then it is like it was deleted, and added a new one.
I know how to do that in ASP.NET, but need help in Adobe LiveCycle using JavaScript.
Please help me to write these two functions, as they are very urgent requirement.
Tarek.

In the event Exit of the 1st subforum.invoice you will find the code to assign the value to it's "brother" on page4.
Also, on the add button i added the code to add a record to the page4 subforum.
To make this work you will have to copy/past the code of the exit event to all fields you want to copy and in the xfa.resolvenode("XXXXXXX[].fieldName") command replace fieldname with the actual name of the field you're at.
I didnt't do anything to te remove line button because i don't know how you want it to work, but, if you want to control the p4 subform with the p1 subform, you shouldn't allow for lines to be removed directly in the p4 subform.
Hope this helps.

How to compare two currency form fields and display a message if the fields do not equal?

My form has 2 fields named Total_1 and Total_2. If one of the fields does not equal the other, a hidden field will display a message in red on the form alerting the user. Otherwise, the message does not display. Looks like a validation script but I would greatly appreciate help in getting it started. Any ideas?
Thanks, Charlie
charlie6067

Since the field values that you want to compare are the results of calculations, you should not normally compare their string values, but rather their numeric values when rounded appropriately (and perhaps then converted to a string). For example, if you have two values that display as 3.14, one could be 3.1400000001 and the other could be 3.13999999999991234. When you get the field values as strings and compare them, they won't be equal though they appear to be. Even some values that are numerically identical won't be equal when compared as strings ("0.0" != "0.00") So the code could be changed to:
// Get the two field values, rounded to two decimals
var v1 = util.printf("%.2f", getField("Total_1").value);
var v2 = util.printf("%.2f", getField("Total_2").value);
// Hide/Show the error message
event.value = (v1 === v2 || (+v1 === 0 && +v2 === 0)) ? "" : "Error message here.";
