How to display information from database using drop down list in JSP?

Hi all.
Like the tile above suggest, I'm having difficulty in obtaining the data as well as displaying them in a drop down list.
For example: If i were to have the following in my database:
SerialNo Food
1 Bread
2 Milk
3 Butter
The drop down list should look like the following:
[Bread][\/]
[Milk]
[Butter]
How do i go around coding it in JSP?
Thanks in advance.

RE: Using Drop-Down List in Express Application

The easiest way to do this is to define a domain for Gender that maps to
a droplist widget. ForteExpress will then automatically display the
widget in any ArrayWindow or FormWindow in which Gender appears. (I
don't think outlinefields support this widget.) There is a documented
customization for adding SQL to the domain to automatically fill it, but
we've found this to be a performance drag. What we usually do is cache
this type of list information on the client, usually by loading it into
arrays of listelement in a service object at user logon. The list is
then ready to go whenever a window needs it, and you can set the element
list of the droplist in PostOpenInit or wherever it seems appropriate.

Subject: Using Drop-Down List in Express Application
On an Express generated Form window I want to use a drop-down list to
define the list of valid values for a database field. The underlying
database field could have a datatype of either integer or character.
For example, on the database we have a Gender column defined. I want to
use a drop-down list that displays descriptions of "Male" and "Female" for
allowed database values of "M" and "F". The Gender column is updateable on
the window.
Any suggestions on the best way to do this? Would we need to do anything
different on Array windows?

Missing Export and Use Drop Down Lists

I cannot export my .mov files to any format other than .mov as the Export and Use drop down lists are missing. When I go to File > Export the text for Export and Use are there followed by blank gray space as if the drop down lists never existed.
I just upgraded to Pro today and had infrequently used QuickTime Player previously. I have the most current version 7.6.5. The other functions appear to be working normally, but I am not a "familiar user" so I can't say for sure.
Any ideas?

Well I could not copy & paste the text from the Movie Inspector, so I have typed it below (except for the complete source info).
Source: C:\....Filename.MOV
Format: 16-bit Integer (Little Endian), Mono, 44.100 KHz
MPEG-4 Video, 1280 x 720, Millions
Movie FPS: 30.01
Playing FPS: 30.01

Current Time: 00:00:00.00
Duration: 00:00:09.80

Current Size: 1280 x 720 pixels
I have also downloaded a couple of iPod hip-hop ad movies (.mov) and they have the same problem (no export drop-down lists), so I don't believe it is the movie format.
I have not tried to uninstall/reinstall QuickTime Pro yet, but wonder if I should....

How to display data from Database individually??? Anyone can help ?

HI,
i i had select a row of data from database using ,
/* Query * From Table RESOURCEORDER where po = selected no and project = selected project */
     public ResultSet getAllData() throws SQLException
     getConnection();
     Statement stmt = conn.createStatement();
     ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
     return rs;
After that , how do i display the data individually ?
Eg select data is ('projectA','7891203-1', '10-4-2005','lcd',2000,'121-45217-8','electrical','pending','donwong')
i want to display them individually, like this in a page
Projectname: /* should display the Project A*/
P.O no:
Date:
Order:
Cost:
Acc no:
Type:
status:
Orderedby:
Can anyone help ? cos i'm new to JSP ......Thanks alot!!!!!
Regards,
khim

I assume PO being a unique key, will always return 1 row from db.
public String[] getAllData() throws Exception
getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
String [] returnValue = new String[9];
while(rs.next())
returnValue[1] = rs.getString("colname");
returnValue[2] = rs.getString("colname");
///and so on
return returnValue;
}Once you get that you could individually view it by setting a loop to run through the returned array.
Hope it helps

Pre-Populating Text fields from a Data drop down list using SQL Server

I'm currently trying to update some of our internal forms which are word based or a basic PDF form you fill in by yourself.
I'm connecting to our SQL server as there are databases stored there for an internal bit of software that hold information
I can use to fill in parts the form.
I have a data drop down list that is dynamically linked to the SQL databass and allows you to select a Project Number from that database, what
I want to do after this is selected is to automatically populate some text fields with the Project name, Account handler and other fields held in the
database.
I've had a look online to see if there is a solution but haven't really found anythig that is similar (although I am new to LC so may have seen it
and not realised) and my Java is non existant.
Has anyone tried this and able to point me in the right directions?
I'm using LiveCycle ES2 version 9.0.0.2 from Creative Suit 5.5 on Windows 7

Hi,
Actually this error does not cause any harm except a presentation inconvenience. In my multi-select prompt I am using variable expression with dynamic repository variable. Dashboard results are correct. Just variable's value does not appear on page (error Error Codes: G689FFB3:SDKE4UTF
Expression: @{biServer.variables['CUR_CAL_PER_MONTH_NAME']}). Pushing "GO" button on the prompt fixing the error but it's actually second execution of the dashboard.
Any ideas ??

How do I add rows to a drop down list. I am using Excel 2008

I am trying to incorporate added rows into a drop down list and am having no luch. Any suggestions?

Any of this help?
Enter the items for your drop-down list into a list on the worksheet, one item per cell. In this example, I'll assume that the month names start in cell E1 and extend down to E12, but they can be in any out-of-the-way location on the worksheet. In Excel terminology, a rectangular group of cells (such as E1 to E12) is called a range.
Select the cell that will contain the drop-down list. If you'd like more than one cell to display the same list, just select them all now rather than setting them up one at a time. (Click and drag to select a range; hold down Ctrl while you click to select non-adjacent cells.)
Choose Data, Validation to display the Data Validation dialog box.
Click the Settings tab.
In the Allow field, select List.
In the Source field, specify the range that contains the list items. In this example, the items are in cells E1 to E12, so type =E1:E12 into the field.
http://support.microsoft.com/kb/141573
NOTE You cannot create a list in a shared workbook. You must remove the workbook from shared use first if you want to create a list.
Every column in the list has AutoFilter enabled by default in the header row. AutoFilter allows you to filter or sort your data quickly.
The dark blue border around the list clearly distinguishes the range of cells that makes up your list.
The row that contains an asterisk is called the insert row. Typing information in this row will automatically add data to the list and expand the border of the list.
A total row can be added to your list. When you click a cell within the total row, a drop-down list of aggregate functions becomes available.
You can modify the size of your list by dragging the resize handle found on the bottom corner of the list border.

How do I get the location bar drop-down list to show the most recently visited page at the top? I have no idea how it's deciding what to display.

In IE when you show the drop-down list from the location bar, it show you all of your most recently visited pages in descending order with the most recent at the top. Firefox is showing me a list that I have no idea where it's getting the pages from or how it's ordering them. It doesn't update the pages or the order when I go to a new page. I have recently switched from IE to Firefox and cannot figure out how to get Firefox to do this; very annoying.

That drop down list doesn't show recently visited pages, but shows list list of most visited sites sorted by what the Mozilla devs call frecency (frequency and recency) and is based on bonus points. It is not possible to have much influence on what shows on that list.
If you want a list of recently visited sites then you can use a smart bookmark e.g. on the Bookmarks Toolbar with the location set to this smart folder.<br />
Name: <b>Recently Visited</b><br />
Location: <b>place:queryType=0&sort=4&maxResults=30</b><br />
You need to close and restart Firefox to make that folder work as intended.

How do I get a URL to display in the Awesome Bar drop down list? Some URL's appear in this drop down but I can't figure how they got there.

There is a drop down list from the Awesome Bar containing some of my most frequently visited sites. How can I add URL's to this list?

The location bar drop-down list shows items based on visited count (bonus points and frecency: frequency and recency) and if you have visited other URLs more often then those will replace other websites.
*https://developer.mozilla.org/en/The_Places_frecency_algorithm
You can't customize this drop-down list and you would have to bookmark websites to have easier access.

How to Pre-select Value in auto drop down list

Hi,
I have an automatically populated drop down list, and I'm trying to have it display with a pre-selected value (in the example 5). I didn't know where to start, so I modified the Dreamweaver code for "Set value equal to" from the Dynamic list function.The list displays, but the value defaults to 0. What am I missing?
<?php
echo '<select name="firstnumber" id="number">';
for ($j=0; $j<11; $j+=1)
echo "<option value=\"$j\" <?php if (!(strcmp(\"$j\",5))) {echo \"selected=\"selected\"\";} ?>$j</option>\n";
echo '</select>';
?>
Thanks,
Tim

The problem is that you have nested PHP tags inside a PHP block. You can't do that. In fact, it's surprising that the code works at all. Normally, nesting PHP tags inside a PHP code block will trigger a syntax error.
Also, your code is very difficult to read because of the way you use double quotes all the time. It's best to use single quotes for strings, except when you need to display the value of a variable inside a string. You can also nest double quotes inside a single-quoted string and vice versa, making for code that's much easier to read without all the backslashes.
This is how I have rewritten your code:
<select name="firstnumber" id="number">
<?php
for ($j=0; $j<11; $j+=1) {
echo "<option value='$j'";
if (!(strcmp($j,5))) {
echo 'selected="selected"';
echo ">$j</option>\n";
?>
</select>

How to show first parameter value in drop down list as a default value dynamically in ssrs report?

Hi,
in my ssrs report i have two parameters, accounts and Manager ,there is a cascading between the accounts parameter and manager parameter, as per the cascading we will get managers names based on the account we selected in the accounts parameter,
my requirement is the first name in the mangers drop down list has to get selected as default value.
please help me with this, it is an urgent requirement.
Thanks in advance,
Naveen

Hi NaveenMSBI,
According to your description, you want to use cascading parameters in the report, if the accounts are selected when you preview the report, the first manager name will be selected from drop down list as the default value. If so, there can be two scenarios:
• If manager is single-valued parameter, we can get Available Values and Default Values from the same query as below. Then when the accounts are selected, the first manager name will be selected as default value.
SELECT managerName FROM table_name WHERE accounts IN (@accounts)
• If manager is multi-valued parameter, we need to use different query for Available Values and Default Values. In this case, please refer to Patrick’s solution.
For more information about Adding Cascading Parameters, please refer to the following document:
http://technet.microsoft.com/en-us/library/aa337498(v=sql.105).aspx
If you have any questions, please feel free to let me know.

Need help using drop down list to calculate fields

I am trying to use a drop down list to control how my field calculate. I have events packages that have multiple tiers. For example, Package One has (2) Tiers. Tier 1 costs $16 & Tier 2 costs $20. So based on the number of guests i want to be able to select the tier and it multiply and give me the total cost for the package. Ex: 2 Guests for Tier 1 = $32. Here is the code i have so far, it is placed under the change handler of the drop down list:
var costPerGuest = 16;
var tier = event.newText;
if (tier == "Tier 1"){
costPerGuest = 16;}
else if (tier == "Tier 2"){
costPerGuest = 20;}
Total.rawValue = String(Guests.rawValue * costPerGuest)
//Total.rawValue = DropDownList1.rawValue;
What happens is when I run this it will not change unless the number of guests will change. So for the example above, if i switch it to Tier 2 after selecting Tier 1, it will not change my Total from $32 to $40.
Any help would be greatly appreciated.

Hi,
I think ,you can use the event of EXIT event of dropdown list.
var costPerGuest = 0;
if (this.rawValue == "Tier1")
costPerGuest = 16;
else if (this.rawValue == "Tier2")
costPerGuest = 20;
else
total.rawValue = Guests.rawValue * costPerGuest;
Hope this helps,
S,Candy.

END;
i have created a Record_Group from Object navigator(name:'rg_name').
and used it in the above code.
after this i try to run the form, i am not able to see the value which i drop-down list
can any one suggest me abt this, and any changes i need to do in the property pallet,...
Thanks

POPULATE_LIST works with both, record groups created at runtime AND at design time.
Try the below code on SCOTT schema with a list item and a button trigger:
Record Group created at design time
DECLARE
     RG_NAME VARCHAR2(10) := 'RGROUP';
     V_DUMMY NUMBER;
BEGIN
     CLEAR_LIST('LIST_ITEM1');
     V_DUMMY := POPULATE_GROUP(RG_NAME);
     IF V_DUMMY = 0 THEN
          CLEAR_LIST('LIST_ITEM1');
          POPULATE_LIST('LIST_ITEM1', RG_NAME);
     END IF;
END;
Record group Created at Runtime
DECLARE
     GROUP_ID RECORDGROUP;
     RG_NAME VARCHAR2(10) := 'RGROUP';
     QUERY_TEXT VARCHAR2(1000) := 'SELECT ENAME, TO_CHAR(EMPNO) FROM EMP';
     V_DUMMY NUMBER;
BEGIN
     CLEAR_LIST('LIST_ITEM1');
     GROUP_ID := FIND_GROUP(RG_NAME);
     IF NOT ID_NULL(GROUP_ID) THEN
          DELETE_GROUP(GROUP_ID);
     END IF;
     GROUP_ID := CREATE_GROUP_FROM_QUERY(RG_NAME, QUERY_TEXT);
     CLEAR_LIST('LIST_ITEM1');
     V_DUMMY := POPULATE_GROUP(RG_NAME);
     IF V_DUMMY = 0 THEN
          CLEAR_LIST('LIST_ITEM1');
          POPULATE_LIST('LIST_ITEM1', RG_NAME);
     END IF;
END;It does work with me both ways, I suggest you test it.

How to make default value in a drop down list

Hi,

1) let drop down box be g_dd.
if g_dd is initial.
g_dd = option2.
endif.
2)
by default same pf-status is used by all the screens in the same program
if sy-dynnr = 'screen_no'. " for screens for which you do not want button to come
set pf-status 'abc' excluding 'fcode_of_button'
endif.
or
data: git_fcode type sy-ucomm with header line.
git_fcode = 'fcode_of_button'.
append git_fcode.
if sy-dynnr = 'screen_no'. " for screens for which you do not want button to come
set pf-status excluding git_fcode
endif.
