I want to supress the encircled value in whole column.

I have multiple data types in one column (dates & text) see table below - I'm wanting to add new column so that one column has date values only and the new column has the text values only.
I guess that I need to add a conditional column but I don't know the language to do it.
I found the solution here:
Basically you duplicate the column, change the column type to one of the types (I changed to date type), therefore the text changed to errors.
I then changed errors to null values.
Then I added a conditional column and substituted the null values for the values in the original column.
See link below for example:

It appear I am not getting latest row when rows have actually same created_at value.
Using $model->latest()->first() - I am getting first row rather than last row of created_at.
How to solve this?
latest() will use the created_at column by default.
If all of your created_at values are the exact same, this obviously won't work...
You can pass a column name to latest() to tell it to sort by that column instead.
You can try:
$model->latest('id')->first();
This assumes you have an incrementing id column.
This will entirely depend on what other data you have in your table. Any query of a relational database does not take the "physical position" into account - that is, there is no such thing as being able to get the "last inserted row" of a table until you are able check some value in the table that indicates it is the probably the last row.
One of the common ways to do this is to have a auto-incrementing unique key in the database (often the Primary Key), and you can simply get the largest value in that set. It's not guaranteed to be the last row inserted, but for most applications this is usually true.
What you need is the equivalent query to be executed
SELECT * FROM Table WHERE created_at = ? ORDER BY ID DESC LIMIT 1
or, in Eloquent ORM
$model->where('created_at', '=', ?)->orderBy('id', 'desc')->take(1)->first();
Keep in mind that you'll probably need other filters, since it is entirely possible other users or processes may insert records at the same time generating the same creation date, and you'll end up with somebody elses records.
I have a BIRT Excel Report with 10 columns. I have a query which executes and brings the data for all the 10 columns.
However, based on one of the input parameters, i need to display just 8 columns. I am able to hide the remaining 2 columns but i would like to delete those 2 columns from the report so that user does not see the hidden columns.
I tried to change the query but i am unable to dynamically set the select parameters.
Is there a way either in Query or in BIRT to remove few columns based on an input condition.
You cannot delete the columns, but it's sufficient to hide them dynamically using the column's visibility expression. You can add an aggregation to the table, using the MAX function for the column data (let's call it max_name).
E.g. if your table column shows the DS column NAME and you want to hide the column if NAME is empty for all rows:
Add an aggration (let's call it MAX_NAME) to the table, with the aggregation function MAX and the expression NAME. Then in the visibility expression of the table column, use !row["MAX_NAME"] as the expression.
After drag and drop the dataset. Right click on column header and select the delete column option.
I have a Tabular Form in my Oracle Apex application. There is a column as UPDATED_DATE. I have set Tabular Form Attributes of this column as below.
When i'm inserting data, UPDATED_DATE column in database table is filling with a value. But when i'm updating existing record, UPDATED_DATE column is not filling with a new value. old date is remaining without changing to a newer data.
How can i solve this ?
The default will only set a value if the field is empty. On your first entry the field is empty, and therefore the updated_Date is set. On updating, the field is allready set, and therefore won't be updated.
You need to create a dynamic action (assuming you use apex 4 or above) and use that to update the date field. Your dynamic action should be triggerd on change of an table row and subsequently set the date field to the current date.
Let me now if you need help on the dynamic action.
I have created a LOV using query; It has 3 columns. When LOV is displayed I want to search a value. But when I type something it search only first column. LOV do not search in other columns except first column.
Is there anybody who knows how to search any value of other column or multi-column search in forms developer 6i?
Thanks.
An Oracle Forms LOV only searches the first column - so you might need to concatenate 2 or more columns into the first column to get what you want.
Otherwise, you may need to make your own custom LOV form.
