APEX_MAIL send results in an HTML table
Apex 3.2I've written a procedure that sends an email with the data of the apex_workspace_activity_log.
I would try to display that data in a table in the email.
All the world done this before?
CREATE OR REPLACE PACKAGE BODY EFSAPX.p_monitor_page_times AS
procedure pr_checkelapsed(p_elapsed in number,
p_toemail in varchar2) is
v_text clob;
begin
wwv_flow_api.SET_SECURITY_GROUP_ID;
for x in (select
application_id,
application_name,
page_id,
elapsed_time
from
apex_workspace_activity_log
where
application_id = 103
and elapsed_time > p_elapsed
and trunc(view_date) > trunc(sysdate-1)
order by
elapsed_time desc)
loop
v_text := v_text || 'Application No: ' || x.application_id ||chr(10);
v_text := v_text || 'Application: ' || x.application_name ||chr(10);
v_text := v_text || 'Page Id: ' || x.page_id ||chr(10);
v_text := v_text || 'Elapsed Time: ' || x.elapsed_time ||chr(10);
v_text := v_text || utl_tcp.crlf;
end loop;
apex_mail.SEND(p_to => p_toemail,
p_from => '[email protected]',
p_body => v_text,
p_subj => 'Elapsed Time Metric Warning');
apex_mail.push_queue('localhost', 25);
end pr_checkelapsed;
END p_monitor_page_times;Gus
As says below, the real HTML involved is very simple, and there's a lot of documentation available for it.
I normally use SQL/XML for generating HTML fragments with the embedded data:
select
xmlserialize(
content
xmlelement(
"table"
, xmlconcat(
xmlelement(
"tr"
, xmlconcat(
xmlelement("th", 'Application No')
, xmlelement("th", 'Application')
, xmlelement("th", 'Page ID')
, xmlelement("th", 'Elapsed Time')))
, xmlagg(
xmlelement(
"tr"
, xmlconcat(
xmlelement("td", application_id)
, xmlelement("td", application_name)
, xmlelement("td", page_id)
, xmlelement("td", elapsed_time)))
order by elapsed_time desc)))
indent size=2) html_table
from
apex_workspace_activity_log
where
application_id = :p_app_id
and elapsed_time > :p_elapsed
and trunc(view_date) > trunc(sysdate-1)
This avoids a lot of tedious messing about with concatenation or substitution in the PL/SQL code and translates the own and valid HTML mark-up with all the tags and attributes in the right place. However as apex_mail API docs notes, the p_body_html parameter must be a complete HTML document (and you will probably need to include any other content and style as well as the table). It's a bit tedious to nest this structure in the query, so a combination method of the lower model for the structure of the base HTML document and this approach to SQL/XML query to generate the table with data structure would be a good idea.
I guess from the wwv_flow_api of . SET_SECURITY_GROUP_ID call that you intend to execute outside a session of APEX? Another option to consider is to create a public page in this app, or as a stand-alone application in the workspace with this query as a region of simple aid report pages/templates, and all the required style embedded in the page. The mail procedure can then use httpUriType.getCLOB to retrieve this page as a complete document which can be passed as p_body_html to apex_mail.send.
Note the requirement that each line in the content cannot exceed 1000 characters. Whatever method you use will have to be built around model/applications are used (where the dash in the code above), or you need to process the content and insert CRLF at the appropriate places before calling apex_mail.send.

Help! > How to send a dynamic HTML table as an email?
Hello
I want to send a dynamic html table as an email
I'm using php/mysql and I have a mysql database
I have a table dynaimc restrained some data from the database
I have a form with a text box to write the email and a button "submit"
I want to send the picture (or the information in the table) when I send the form
is this possible?
Help, please!
OK, now I have you. You create a queary to select the data you want, and then copy the following code
$data = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc));
While ($row = {mysqli_fetch_array ($data))}
Mail to the owner of the form
$header = "from: [email protected]\n".
. "Reply-To: $email\n";
$subject = 'DB in emails data';
$email_to = "[email protected]";
$message =
$row ["FirstName"].
$row ['last_name']
;
}
mail ($email_to, $subject, $message, $header);
So, for each column, you will enter in this
$row ["FirstName"].
So if the column reported, you would put
$row ["State"].
I hope this is the answer you are looking for.

How can I filter the data and display it in the html table?
Hello
How do I filter data that contains the database table and already displayed in html table, then when the user write a data to filter or search, it will automatically display the data in html table. ?
can someone help me to do this? Here is my php code for the table that will display the data:
<?php $servername = "localhost"; $username = "root"; $password = "pass"; $dbname = "ses"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT No, Calon, ID, Jurusan FROM candidates"; $result = $conn->query($sql); ?> <?php if ($result->num_rows > 0) { echo "<table > <tr> <th>NO</th> <th>Candidate</th> <th>ID Number</th> <th>Programme</th> <th>Edit</th> <th>Delete</th> </tr>"; // output data of each row while($row = $result->fetch_assoc()) { echo "<tr> <td align='center'>" . $row["No"]. "</td> <td>" . $row["Calon"]. "</td> <td>" . $row["ID"]. " </td> <td>" . $row["Jurusan"].

Thank you.
You must first create a search form for the user to enter a search word:
Then create a page named search_page.php and insert the following code into it and save it. The code in red below Gets information from the search form field name = "Calon" and the SQL query finds in the "Calon" database field for a game.
<>
$servername = "localhost";
$username = 'root ';
$password = "pass";
$dbname = 'his ';
Create the connection
$conn = new mysqli ($dbname, $servername, $username, $password);
Check the connection
If {($conn-> connect_error)
Die ("connection failed:".) $conn-> connect_error);
}
$Calon = trim($_POST['Calon']);
$sql = (' SELECT no, Calon, ID, Jurusan candidates WHERE Calon = "'.") $Calon.' » ") ;
$result = $conn-> Query;
?>
<>
If ($result-> num_rows > 0) {}
ECHO '.
";NO. Candidate Identification number Program Edit Delete each line output
While ($row = {$result-> fetch_assoc())}
ECHO '.
" . $row ["no"]. " " . $row ["Calon"]. " " . $row ['ID']. " " . $row ["Jurusan"]. " Edit Delete }
ECHO '.
} else {}
echo "0 results."

I'm new to jQuery, animate edge and this Forum... and pretty novice to HTML5 and CSS3, so I could really use a help please :-)
I have a JSON file with many records. I wish that each record to represent a row in an html table. The JSON file gets written each night courses, and the number of records in the JSON file will often change. I want to write the values of the file in a dynamic html table and then use different animations to set the table on the stage! Possible? Or is there a better way?
My JSON example:
[{'id': 1,}]
'Division': 'Austin ',.
'txt_one': 9,.
'txt_two': 5,.
'txt_three': 20,.
"txt_four": 5
},
{"id": 2}
'Division': 'Houston ',.
'txt_one': 0,
"txt_two": 4.
'txt_three': 0,
'txt_four': 7
},
{"id": 3}
"Division':"Phoenix. "
'txt_one': 1,.
'txt_two': 2.
"txt_three": 3.
"txt_four": 6
}]
(1) the html option (table symplistic).
(A) code:
var myList = {lines: []}
{'id': 1, 'Division': 'Austin', 'txt_one': 9, "txt_two": 5, "txt_three": 20, "txt_four": 5},
{'id': 'Division' 2: "Houston", "txt_one": 0, "txt_two": 4, "txt_three": 0, "txt_four": 7},.
{'id': 3, 'Division': 'Phoenix', 'txt_one': 1, 'txt_two': 2, 'txt_three': 3, 'txt_four': 6}
]};
var lines ="";
.each $(myList.rows, {function(index,item)}
"lines += '.
'+' + item.id "+ point. "Division. '+ item.txt_one +' '+ item.txt_two +' '+ item.txt_three +' '+ item.txt_four +' } );
.html ("$("Text") sym.
"+ lines +".
");SYM. $("table") .css ("width", sym.$("Text").width ());
SYM. $("table, td") .css ({'border': "1px solid black", "border-spacing": "5px"})
SYM. $("tr") .css ("background", "#acc5a0");
SYM. $("td") .css ("text-align", "center") .css ("color", "white");
(B) back on stage:
(2) the display option.
Could you please send a file with your model of symbol?
I mean your line template.

Hi there, I don't have an exact answer as to why your code behaves like that.
The best thing I can say is that you use Web Inspector to debug your application. If there are errors as they appear in the Console of the Web Inspector, and you will be able to solve much better.

Urgent please. I have a table with two rows. In each line, I'll add a few separate images in columns/cells. On the first line, the images will fill all the columns. But (!) on the first line, I'll add pictures only on left (fixed to the left) and the right (fixed to the right) and I want every cell of these two broad 8px, so I can keep the Middle wide enough to add text and empty. But I can't do it!
Here's a JSfiddle my work online.
http://jsfiddle.NET/mdermez32/pcmz4ysk/2/
Why can't I just have two rows of a table and each line have two or more cells with fixed width?
You can, but you have no guarantee in a way that will be rendered (or display) in all browsers on every computer and mobile device out there.
HTML tables are elastic by nature and love to develop according to their content and fill any container they are in (div block etc.). Trying to control a single table to perfection perfect pixel is bound to frustrate you.
Nested tables has long been the most reliable solution for the specific page layouts such as you are aiming for.

Display the values of the Page element in HTML table
Hi all
could you please help me with the below? I want to have a table in the HTML area and to display in the table of elements of the Page of the page.
I got the code like this:
{
< table >
< tr > < td > & P1_ECEMEA_ASSISTANCE < table > < /tr >
< tr > < td > & P1_ECEMEA_WIP < table > < /tr >
< /table >
}
It shows the element of the Page names in the form of text, not the values.
However, this code without the tags table:
{
ECEMEA request for Assistance of the CQT: & P1_ECEMEA_ASSISTANCE.
ECEMEA CQT Work in Progress: & P1_ECEMEA_WIP.
}
Works and Page element values are displayed.
Is it possible to display the values of the Page element in the HTML table at all or should I use a different method to show the values in a table? The above is only an excerpt of the code. I need to display about 30 items in Page, put in shape in a table with headers.
Please let me know what kind of region is the best to use, or if I have to use only a few symbols of escape in the table code...
Thank you and best regards,
VladimirVladimir,
Looks like you're missing the period after the substitution variables.

JSF component to create a html table view
Jdev 11.1.1.4
I would like to know what is the preferred jsf component create a view in an HTML table.
My screen must have a 'head of column table' and 'line the table header '. It is composed of several rows and columns. In each cell, I need to insert a different inputText mapped to the different attributes of VO. I have many attributes of VO... (one per cell). Something like a MS-Excel crosstab table.
I am currently using a real html table, but I'm having some problems when the contents are adjusted inside a cabinet (sometimes the right side of the table out of the box of control panel). I also have problems with the help toolltip (property shortdesc) text that sometimes does not display exactly where are the input fields and the shadow of this ToolTip apears incorrectly overlapping content (in fact the ToolTip apperars in one place and he the shadow in a different place from the screen like a gray rectangle.)

My html table does not appear on the 2nd tab on the Panel (muse widget)
The same table works fine on the first tab, however when I try to click on the second table in the page mode or overview of the browser on browser, my table is not displayed. Tips to solve this problem?
If I get this right, you use the tabbed panel widget to display an HTML table in each of the tabs. If this is the case, please make sure that you insert the HTML content on each content area of the tab respectively. To check this, switch between tabs in design mode to check your content.
Thank you
