I am using phpMyadmin to store my database and I would like to insert 2 columns of data onto the bind popup and the code is below
.bindPopup(healthcare[i][0])
.bindPopup(healthcare][i][3])
My aim is to insert the 2 columns of data into one popup.
Do any of you know how to help me with this problem? Thank you
The second call actually overwrites the first one. You would need to concatenate results, e.g. like this:
.bindPopup(healthcare[i][0] + ' ' + healthcare][i][3]);
You would probably want something more sophisticated than that, e.g. with HTML tags, etc.

In my model I want to loop through the database which contains multiple columns (see example) by an event. The idea behind it is that I want to create dynamic events based on the rows in the database.
But I've no clue how to iterate through a database in anylogic and also was not able to find an example of a loop with a database.
The dummycode of my problem would look something like this:
For order in orderdatabase:
Create order based on (order.name, order.quantity, order.arrivaltime, order.deliverylocation)
Where order in the loop is every row of the database, and the value on which the creation is based based on the different column values of that specific row.
Can somebody give me a simple example of how to create such a loop for this specific problem.
Thanks in advance.
Use the database query wizard:
put your cursor into a code field
this will allow you to open the database wizard
select what you need (in your case, you want the "iterate over returned rows and do something" option
Click ok
adjust the dummy code to make it do what you want
For details and examples, check the example models and the AnyLogic help, explaining all options in detail.
I have hundreds of rows of raw data in a CSV. It is stacked like this:
ID.....SS.....P.....Window
S1235...345...48.....Fall
S1235...460....68....Winter
S1123....389....50....Fall
S1123.....598....98.....Winter
What I would like to do is match it up so that all of the IDs match with similar ID on one row only (without doing a manual copy and paste) so it looks like this:
ID.....SS.....P.....Window
S1235...345...48.....Fall..... S1235...460....68....Winter
S1123....389....50....Fall.....S1123.....598....98.....Winter
I don't care if there are multiple columns...because I will manually delete what I don't need. What I need is for all the data with the same ID to appear on one row only. Each piece of information needs to be in it's own cell.
I appreciate the help in advance...I'm not very good with this stuff...but it would be a HUGE time saver if you can help me out!
sorry for my noob question,
I'm currently writing a perl web application with sqlite database behind it.
I would like to be able to show in my app query results which might get thousands of rows - these should be split in pages - routing should be like /webapp/N - where N is the page number.
what is the correct way to query the sqlite db using DBI, in order to fetch only the relavent rows.
for instance, if I show 25 rows per page so I want to query the db for 1-25 rows in the first page, 26-50 in the second page etc....
Using the LIMIT/OFFSET construction will show pages, but the OFFSET makes the query inefficient, and makes the page contents move off when the data changes.
It is more efficient and consistent if the next page starts the query at the position where the last one ended, like this:
SELECT *
FROM mytable
ORDER BY mycolumn
WHERE mycolumn > :lastvalue
LIMIT 25
This implies that your links are not /webapp?Page=N but /webapp?StartAfter=LastKey.
This is explained in detail on the Scrolling Cursor page.
You should do something like this:
SELECT column FROM table ORDER BY somethingelse LIMIT 0, 25
and when the user clicks on page 2, you should do:
SELECT column FROM table ORDER BY somethingelse LIMIT 25, 50
and so on..
You'd most likely be using the LIMIT and OFFSET keywords, something like this:
$sth->prepare("SELECT foo FROM bar WHERE something LIMIT ? OFFSET ?");
$sth->execute($limit, $offset);
while ( my #row = $sth->fetchrow_array ) { # loop contains 25 items
The $limit and $offset variables would be controlled by the parameters passed to your script by html/cgi/whatever features.
Pagination is one of those problems a lot of CPAN modules have already solved. If you're using straight SQL, you could look at something like DBIx::Pager. You might also want to check out something like Data::Pageset to help you manage creating the links to your various pages. If you're using DBIx::Class (which is an excellent tool) for your SQL queries, then DBIx::Class::ResultSet::Data::Pageset will make this very easy for you.
Essentially handling the SQL is one end of it, but you'll also need to solve various problems in the templating aspect of it. I'd encourage you to have a look at these modules and maybe even poke around CPAN a little bit more to see where somebody else has already done the heavy lifting for you with respect to pagination.
I am using TinyMCE to allow users to write in what will eventually be submitted to a database.
TinyMCE includes a button which will insert a "pagebreak" (actually just an HTML comment <!--pagebreak-->).
How can I later pull back everything up to the first occurrence of the pagebreak "tag"? There might be a significant bit of data after that tag which I could discard via php later, but it seems like I shouldn't even bring it back. So I can I SELECT just part of a column if I never know how far in to the data the <!--pagebreak--> will be?
EDIT:
The below answer does work, and will get me where I need to go.. I am just curious as to if there is an equally simple way to handle bringing back the whole column if it is short and thus the pagebreak tag doesn't exist. With the below solution, if no pagebreak is found, an empty string is returned.
If not, then I can easily handle it in the code.
Something like this should get you everything up to the <!--:
SELECT SUBSTRING(my_col FROM 1 FOR POSITION('<!--' IN my_col)-1) AS a_chunk
FROM my_table
Reference for string functions.
Edit:
Just putting OMG Ponies' words into SQL:
SELECT CASE WHEN position('<!--' IN my_col) > 0
THEN SUBSTRING(my_col FROM 1 FOR POSITION('<!--' IN my_col)-1)
ELSE my_col END AS a_chunk
FROM my_table
It sounds like you'll also want a check on the length of the text; whether or not there is a page break. You can use CHARACTER_LENGTH() for that.
why not create another column in your mysql table to store integer value of the position where <!--pagebreak--> is. You'll calculate this value in your script and store this value at same time when you insert the html generated by tinymce.
Then in later retrievals use the value in that column to select the substring from 1 up to the value. This should make your query simpler and maybe improve query performance?
I have a large table which inserts data into the database. The problem is when the user edits the table I have to:
run the query
use lots of lines like value="<cfoutput>getData.firstname#</cfoutput> in the input boxes.
Is there a way to bind the form input boxes to the database via a cfc or cfm file?
Many Thanks,
R
Query objects include the columnList, which is a comma-delimited list of returned columns.
If security and readability aren't an issue, you can always loop over this. However, it basically removes your opportunity to do things like locking certain columns, reduces your ability to do any validation, and means you either just label the form boxes with the column names or you find a way to store labels for each column.
You can then do an insert/update/whatever with them.
I don't recommend this, as it would be nearly impossible to secure, but it might get you where you are going.
If you are using CF 9 you can use the ORM (Object Relation Management) functionality (via CFCs)
as described in this online chapter
https://www.packtpub.com/sites/default/files/0249-chapter-4-ORM-Database-Interaction.pdf
(starting on page 6 of the pdf)
Take a look at <cfgrid>, it will be the easiest if you're editing table and it can fire 1 update per row.
For security against XSS, you should use <input value="#xmlFormat(getData.firstname)#">, minimize # of <cfoutput> tags. XmlFormat() not needed if you use <cfinput>.
If you are looking for an easy way to not have to specify all the column names in the insert query cfinsert will try to map all the form names you submit to the database column names.

This is indeed a very good question. I have no doubt that the answers given so far are helpful. I was faced with the same problem, only my table does not have that many fields though.
Per the docs EntityNew() the syntax shows that you can include the data when instantiating the object:
artistObj = entityNew("Artists",{FirstName="Tom",LastName="Ron"});
instead of having to instantiate and then add the data field by field. In my case all I had to do is:
artistObj = entityNew( "Artists", FORM );
EntitySave( artistObj );
ORMFlush();
NOTE
It does appear from your question that you may be running insert or update queries. When using ORM you do not need to do that. But I may be mistaken.
