How to validate Date value in Text Column

Hi All,
I have entered DATE value in text item field(Char Data Type), Now how can i validate, the entered date is valid or not.
Thanks in advance.

Well, the easiest way would be to make the item of datatype DATE.
Another possibility is to try to convert the given value to a date in the WHEN-VALIDATE-ITEM-trigger, like
DECLARE
dt DATE;
BEGIN
dt:=TO_DATE(:BLOCK.ITEM);
-- if code comes here, the date is valid
EXCEPTION
WHEN OTHERS THEN
    -- seems to be no valid date
    MESSAGE('Error');
    RAISE FORM_TRIGGER_FAILURE;

How to validate date picker value

Hi,
When a date is entered manually in the date picker .ie 01/03/08 the year 08 is saved as 0008 in the database rather than 2008. How to validate the value in date picker to save the year as 2008 instead of 0008.
Ven

The date picker does not always "store" the value for you - you create it with a particular format such as DD-MON-YY and then like any character to date field you need to be careful to use a format mask and to_date. Alternatively, change the format to DD-MON-YYYY.
Are you using this in a query or defined as a page item? Do you have the app on the APEX site?

How to validate Date

Hi,
We have a date field in the form. I am validating date format as YYYY-MM-DD, validation works fine. But If user enters invalid date, how to validate date? For examples:
2006-02-31 It is an invalid date. How can i validate it.
If anybody have sample code, it will help me a lot.
thanks
Neopal.

Hi Neopal,
You can use something like the following to test the date is valid, use the validation event on the <Field> which you want to validate to call a Rule something like this (not complete)..
<Rule name='isDateValid'>
 <RuleArgument name='date'/>
 <block>
 <script>
 var dateToTest = env.get('date');
 var formatter = new java.text.SimpleDateFormat('YYYY-MM-DD');
 Date validDate = formatter.parse(dateToTest);

How to insert varchar2 value in timestamp column in table?

When you do this, there is no fundamental difference between "08:00:00" and "here's your sign".
Data should always be stored in the correct data type. For dates and times, that data type is either DATE or TIMESTAMP. Period.
in this format: 08:00:00
now i have to insert this value in timestamp column in table. how to insert this value in timestamp column?
Hopefully as remediation to the original bad design.

How to set default values for boolean columns

I'm trying to deploy some content types and columns into a site with a feature. All it's ok, except that I'm trying to set a default value for boolean columns with no success.
I've tried to set default value at column level:
<Field ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DisplayName="Se publican noticias en español"
Type="Boolean" Hidden="FALSE" Group="Columnas ShaCon" >
<Default>TRUE</Default>
</Field>
and at content type level:
<FieldRef ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DefaultValue="TRUE" Required="TRUE" />
But in any case, when i create a new item with this content type, default value is applied.
Can anyone tell how to set default values for boolean columns?
Thanks in advance,
Regards,
Sergio

In the field definition you can set
<Default>1</Default>
or
<Default>0</Default>

Model of how APEX handles data (values)?

Reference {thread:id=2486655}
I'm trying to get a model of how APEX handles data (values). There are several places(?) that data (values) can exist. Or so it seems. I'm trying to understand how these work -- to put all the pieces together.
Question:
A) Where data can be?
1) In the database
2) In the session
3) Rendered -- and hence displayed on the screen, if a displayed value -- but not in the session
4) In perhaps(?) some working memory pool(?) but different from the page rendered values I see on the screen?
5) Other?
Why do I think this is relevant?
Question:
B) If there are rendered values and session values different from the rendered values, then when code executes, which of these values (rendered or session) is it executing against?
And maybe the answer is, "You don't understand what's going on." Yes, "Exactly!" Hence the question.
Best wishes,
Howard

Howard (DBA in Training) wrote:
I'm putting this together now. For example:
I set the value of a Page Item (say, :P2_DATA) to "BEFORE" in a Before Region process and change it to "AFTER" in an After Region Process. 'BEFORE' was displayed on the screen but 'AFTER' was in the session state. So I see that PL/SQL changes these values in the session state. But it doesn't "go back" to change the HTML after the region has been rendered -- hence we see BEFORE shown on the screen. (I'll have to think about what a Dynamic Action does.)
Also, if a page item has a default value, say 'DEFAULT' then that value doesn't get into the session state. At least, not with my current settings. Oh, that explains a lot of confusion!! I suppose there's a logical reason for this but who would expect default values to be differently from other PL/SQL operations on the item?
Questions:
1) So why does a default value not get put into the session state?Several reasons, among them:
*1. When/why is the value required?* Region items (and thus their source and default values) are rendered in region/item sequence order. The item's source/default value would therefore not be available in session state until it's rendering point. This is frequently later in page show processing than the value is actually required, such as the common use case of including a data value in the page or region title. Setting the value in a Before Header/Regions computation or process makes it available as required before the item is actually rendered.
*2. The rendered page might not be submitted.* Default values are typically set when a page will create a new row. Consider the situation where the user clicks a "Create" button and is presented with an order entry form containing several default values. They then decide they don't want to create a new order after all, and navigate away from the form page via some mechanism that uses a redirect rather than a submit (such as a default "Cancel" button). This means that no page submit processing is performed, and generally that no session state management is performed. If the default values were set in session state, the order entry page would contain the default values for the non-existent order despite the user never submitting it. This may have unwanted side-effects if these values are referenced elsewhere in the application, and therefore would require extra session state management to be built into the application.
*3. A rendered item might not be submitted with the page.* Per the HTML specification, the values of disabled controls unchecked checkboxes are not POSTed on page submit. Consider a situation where a checkbox item is set with several default values, but the application requires that the checkboxes be cleared and disabled by a dynamic action if the user chooses certain options from a select list. In this case, on page submission no values are submitted into session state for the checkbox item. If the defaults had been set in session state, then the application would be in an inconsistent state, with the user-selected option indicating that none of the checkboxes were checked, but with session state holding values showing that they were. This would require additional processing to ensure that the application's state was consistent before saving it to the database.1
2 & 3 are particularly significant in basic wizard-generated applications. Doing things in this way, the wizard-generated DML and navigation "just works", without the need for additional session state management.
2) Is there a Page Item setting that causes the default value to be saved to the session state?No. Hopefully the explanations above provide sufficient reason to show why this is genearlly not desirable. On the rare occasions when it is required, set the session state value using a computation or process.
1 There are other reasons—mainly security related—that make it good practice to perform such checks in more complex and internet-facing applications anyway.

How to use Special value set with Column clause to display addtional column

Dear Yaseen,
To get the value in formula cumulative,after you have created the formula for that particular key figure,go to edit and click on tab "calculations".
In that select overall result as 'count all values not equal to zero' and single result as 'count all values not equal to zero' .
And mark the cumulative check box underneath.
I hope you get the desired result and please do me favour .

How to validate date columns in tabular forms?

Hi,
I have two date columns in a tabular form
1.Start_date 2.End_date so here i need to validate the end_date as should not be lesser value than start_date column
so any solution for this?

Hi,
use a validation of type "Function returning boolean" and the following code:
IF to_date(:YOUR_END_DATE,'YYYY-MM-DD') < to_date(:YOUR_START_DATE,'YYYY-MM-DD') THEN RETURN FALSE;
ELSE RETURN TRUE;
END IF;The date format is of course in your choice.
Hope this helps...

Gouri,
You can just simply edit to each column's report attribute. For example,
To set default date,
Default Type: PL/SQL Expression of Function
Default: sysdate
To set default text,
Default Type: PL/SQL Expression of Function
Default: *'CLERK'*
If you still have an error, what is the error message?

"How to get distinct values of sharepoint column using SSRS"

Hi,
 I have integrated sharepoint list data to SQL Server reporting services. I am using the below to query sharepoint list data using sql reporting services.
<Query>
 <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction>
 <Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems">
 <Parameters>
 <Parameter Name="listName">
 <DefaultValue>{GUID of list}</DefaultValue>
 </Parameter>
 <Parameter Name="viewName">
 <DefaultValue>{GUID of listview}</DefaultValue>
 </Parameter>
 <Parameter Name="rowLimit">
 <DefaultValue>9999</DefaultValue>
 </Parameter>
 </Parameters>
 </Method>
<ElementPath IgnoreNamespaces="True">*</ElementPath>
</Query>
By using this query, I am getting a dataset which includes all the columns of sharepoint list. Among these columns, I wanted to display only 2 columns (i.e Region and Sales type) using chart. I have created a Region parameter but when I click preview, the drop down box is giving me all the repeatative values of region like RG1,RG1,RG1,RG2,RG2,RG2,RG2,RG3.......... I wanted to display only distinct values of Region parameter so that whenever end user select region from the parameter drop down, it will display the respective value of Sales type column.
Also when I select only RG1 parameter, it is giving me a chart including the sales type of all the Regions. (it should display me only the sales type of RG1) How can I link these 2 columns so that they will display the values respectively.
 I would really appreciate if anyone can help me out with this.
Thanks,
Sam.

Hi Sam,
By code, the CAML language doesn’t have any reserved word (or tag) to set this particular filter to remove duplicate results.
In this case, we could use the custom code to get distinct records.
Here are the detailed steps:
1. Create a hidden parameter that gets all the records in one field.
Note: Please create another dataset that is same of the main dataset. This dataset is used for the parameter.
2. Create a function that used to remove the duplicate records.
Here is the code:
Public Shared Function RemoveDups(ByVal items As String) As String
Dim noDups As New System.Collections.ArrayList()
Dim SpStr
SpStr = Split(items ,",")
For i As Integer=0 To Ubound(Spstr)
If Not noDups.Contains(SpStr(i).Trim()) Then
noDups.Add(SpStr(i).Trim())
End If
Next
Dim uniqueItems As String() = New String(noDups.Count-1){}
noDups.CopyTo(uniqueItems)
Return String.Join(",", uniqueItems)
End Function
3. Create another parameter that will be used for filtering the maindata.
Please set the available value to be =Split(Code.RemoveDups(JOIN(Parameters!ISSUE_STATUS_TEMP.Value, ",")), ",")
And the default value to be the value you what such as the first value:
=Split(Code.RemoveDups(JOIN(Parameters!ISSUE_STATUS_TEMP.Value, ",")), ",").(0)
4. Go to the main dataset. Open the property window of this dataset.
5. In the “Filters” tab, set the filter to be:
Expression: <The field to be filter>
Operator: =
Value: =Parameters!Region.Value
The parameter “Region” should be the parameter we created in the step3.
Now, we should get distinct values of SharePoint columns.
If there is anything unclear, please feel free to ask.
Thanks,

How to pass date value to an UDF

Hi,
I am working in SDK UI. I have created a form. In this form there is a edit text box. I have to pass a date value to that object. I have taken a variable and pass a date value in "yyyy/mm/dd" format. When I am assign this variable to the object to pass the date value to that object then I am getting an error. The error is "Unable to cast object of type 'system.string' to 'system.IFormatProvider' ".
I have written the code like this :------>
Dim AtenDate As String
AtenDate = '2007/08/01' ' format "yyyy/mm/dd"
Dim txtEditDt As SAPbouiCOM.EditText
oItem = oForm.Items.Item("11")
txtEditDt = oItem.Specific
txtEditDt.String = AtenDate.ToString("dd/MM/yyyy")
After the last line the error is getting fire.
Please help me how I can pass the date value to that object.
Please help me. It is very urgent.

Date and Double conversion is really a confusing thing in B1-SDK programming in the beginning.
But once you got it it's okay.
When working with date-time and doubles (System and SBO-Price/SBO-Quantity), you should always take care about the language of...
...system (windows)
...SBO User Interface
These two formats could make trouble when the programming has been made only for a specific configuration of these two.
The third format for SDK-Programming is
...the SBO-DB-Format, which is language-independent and always a String
Here are some rules:
EditText.String ALWAYS returns the value you see on the SBO GUI. It depends on the SBO Date, Price etc.-Format the USER has configured in the Administration. Consider that the user has (for example) the possibility to choose a "#" (or whatever) as decimal-seperator. Direct (implicit) conversion of such a string to a double will fail at the latest now.
The savest way to get a .NET-Double or DateTime- Value from EditText.String are the conversion methods of SBOBobs-Object (see SDK-help -> BoBridge, Format_MoneyToString...etc.).
I think it's a good idea to write some wrapper functions for that methods, cause they always need a recordset which blows up the code too much.
EditText.Value always (system/sbo-language independent) returns the value as a String in DB-Format (Double as "12345.126700" and date as "20070930".
For that you must asure that the EditText is bounded to a format-corresponding datasource. Price, Quantitiy.... if you need a double.
If your "price"-field would be bound to ShortText and the user wants (assuming the example from above) a "#" for decimal-point, then a GUI-seen value like "12,421#12" is also returned as "12,421#12" by EditText.Value. But If bound to Price-DataSource it's "12421.120000"
=> So always do a DataBind to the Data - Type which is needed is recommended for this to work!
In my case EditText.String and -Value is mostly (only...? needed for B1-System-Forms where using of DataSources is restricted.
The prefered way of read/write values is the
UserDataSource.ValueEx and DBDataSource.GetValue/SetValue-method. It's also always in DB-Format as EditText.Value before, but gives much more performance.
Once you got some conversion-functions for "DB-Format-String" to ".NET-DataType" and vice verca (I've defined some .NET - System.Globalization.XXXFormatInfo-Objects for that) all of your problems are things of the past

How to represent multiple values in one column

Hi,
I need some help in designing a schema for this problem.
I have :
- 4 domains
- In each domain there will be many groups
- users belong to multiple groups in multiple domains
Eg.
user1 might be in groups g1, g2 and g3 in domains d1, d2
In a text file I represent it like this:
user1 | d1 | g1,g2,g3
user2 | d2 | g1, g2
etc.,
How do design a schema for this. I don't like the idea of having comma
separated values in columns.
Thanks.

Good instincts. You don't want to have comma-separated values in a column, that violates basic normalization rules.
You would probably want something like this
CREATE TABLE usr (
user_pk
user_id
CREATE TABLE grp (
group_pk
group_id
CREATE TABLE domain (
domain_pk,
domain_name
CREATE TABLE domain_group (
domain_pk,
group_pk
CREATE TABLE user_group (
user_pk,
group_pk
)where you create separate tables that map different things to each other. domain_group shows which groups are associated with a particular domain, user_group shows which users are associated with a particular group.

How to get a value from a column inside a table

Hi,
I have got the following problem. I have got a table with some data inside. And a new column, which is not in the dataprovider. Now i search for an opportunity to go through the rows of the table and check the value of this column. I cant do this with the dataprovider or the rowset. My question is now how can i do this? The table object doesnt seem to have a corresponding method.
Thanks in advance for help
Acinonyx

this is some code you can use (based on Winston's and others' tips):
put this in you page bean:
private HashSet selectedRows = new HashSet();
public boolean isSelected() {
TableRowDataProvider trdp = (TableRowDataProvider)getBean("currentRow");
if (trdp == null) {
return false;
RowKey rowKey = trdp.getTableRow();
if (this.selectedRows.contains(rowKey.getRowId()))
return true;
else
return false;
public void setSelected(boolean b) {
TableRowDataProvider trdp = (TableRowDataProvider)getBean("currentRow");
RowKey rowKey = trdp.getTableRow();
if (checkbox1.isChecked()) {
this.selectedRows.add(rowKey.getRowId());
Object v = this.t_fotoDataProvider.getValue("fieldName", rowKey);
} else {
this.selectedRows.remove(rowKey.getRowId());
and then bind the "selected" property of the checkbox column to the "selected" property of the page bean.
Now, eveytime the page is submitted, you can do something useful, for example, in the setSelected() method (the row that starts with Object v = ... get's the value of some field corresponding to the checked row)
