Retrieving Data from SQLite and make link with the ID of the retrieved data?

Hello, first of all sorry if my english is bad as im from Mexico.
I using HTML/Javascript/SQLite, and im having an issue while retrieving data from SQLite, all my querys work right, but when i try to select an Id, the Name, Firstname, and Lastname and only use the Name, Firstname and Lastname to print on screen and the Id to use as a link or OnClick query with the id more info from the name of the person..
My SQLite query is the next one.
var sql = "SELECT [sis_persona].[idPersona], [sis_persona].[Nombre], [sis_persona].[Paterno], [sis_persona].[Materno] FROM [sis_persona] WHERE Nombre LIKE '"+ nombre1+"%' AND Paterno LIKE '"+ paterno1+"%' AND Materno LIKE '"+ materno1+"%' ORDER BY [sis_persona].[Nombre], [sis_persona].[Paterno], [sis_persona].[Materno] LIMIT 20";
And my ResultHandler is the next one:
    row = document.createElement("tr");
                cell = document.createElement("th");
                cell.innerText = "Nombre";
                row.appendChild(cell)
                cell = document.createElement("th");
                cell.innerText = "Paterno";
                row.appendChild(cell)
                cell = document.createElement("th");
                cell.innerText = "Materno";
                row.appendChild(cell)
                tbl.appendChild(row);
                var numRows = result.data.length;
                for (var i = 0; i < numRows; i++)
                    // iterate over the columns in the result row object
                    row = document.createElement("tr");
                    for (col in result.data[i])
            var ea = result.data[i];
            cell = document.createElement("td");
            var a = document.createElement( 'a' );
            a.setAttribute('HREF','#');
            var txt = document.createTextNode( ea.Nombre );
            a.appendChild( txt );
            a.onclick = function() {querytest(ea.idPersona);};
            row.appendChild( a );
            row.appendChild(cell);
                        cell = document.createElement("td");
            var a = document.createElement( 'a' );
            a.setAttribute('HREF','#');
            var txt = document.createTextNode( ea.Paterno );
            a.appendChild( txt );
            a.onclick = function() {querytest(ea.idPersona);};
            row.appendChild( a );
            row.appendChild(cell);
                    cell = document.createElement("td");
            var a = document.createElement( 'a' );
            a.setAttribute('HREF','#');
            var txt = document.createTextNode( ea.Materno );
            a.appendChild( txt );
            a.onclick = function() {querytest(ea.idPersona);};
            row.appendChild( a );
            row.appendChild(cell);
                    tbl.appendChild(row);
And this is where i have the problem, it print three times and i dont know how to take print only the result and make a link with the id from the query.
var ea = result.data[i];
            cell = document.createElement("td");
            var a = document.createElement( 'a' );
            a.setAttribute('HREF','#');
            var txt = document.createTextNode( ea.Nombre );
            a.appendChild( txt );
            a.onclick = function() {querytest(ea.idPersona);};
            row.appendChild( a );
            row.appendChild(cell);
Anyone have any ideas?
Sorry again if my english is bad.
Thanks in advance

How to retrieve data from database to the structure(complicated)

Hello everyone:
I want to retrieve data from database to the structure. but the structure defined like this below:
TOLERANZOB LIKE QAMV-TOLERANZOB
TOLERANZOB1 LIKE QAMV-TOLERANZOB
so how can I retrieve the data from the database ? make sure that the two fields contain data both.
Thanks in advance .
Regards
Nick

Hi Nick,
To retreive data for TOLERANZOB from QAMV,
If you know the key fields then use
SELECT SINGLE TOLERANZOB FROM QAMV INTO TOLERANZOB WHERE keyfields.
else, you can use
SELECT TOLERANZOB FROM QAMV UPTO ONE ROWS INTO TOLERANZOB WHERE....
Once you retreive the data using the select query, you can check if it is initial and if not move the data from TOLERANZOB to TOLERANZOB1.

Failed to retrieve data from database?

I am a new user
When I try to Preview a document I am prompted to enter in database information.
I have tried a few times to connect to my server and
continuously keep getting the same error page
No matter what I enter in the two fields, this is what pops up.
"Failed to retrieve data from database"
" Details: ADO Error Code:0x
Source: Microsoft OLE DB Provider SQL server
Description: Invalid object name: ScratchWO.dbo.tblsyslistviewprint'.
SQL State:42502
Code:208"
When the OLE DB(ADO) page opens and asks for a server and a database, what is needed to stop the error from happening
If anyone has any information that would be great !

SQL State:42502 means an user authorization error. Check the user and it's access to the target database.

How to Retrieve data from database into another form ?

Good Day!
Am currently new at JSP. I've been studying it for awhile and still getting the hang of it. We are working on a project.
Editing a given data. We have to retrieve the given data and post it to another form "Editing form".
Since we can retrieve data using JSP but how are we going to post it to another form? I mean how are we going to transfer data from one form to another?
Can anyone help me with codes please..

The client is a web browser.
The client submits a request (click a link, visit a form)
The server gets to respond to this
- look at request parameters from the client
- access database
- produce resulting html page
- send page back to client.
The standard pattern is to retrieve data from the database in java code, and then load that data into a bean.
You then make that bean available as an attribute
It is then available for use in your JSP - either <jsp:useBean> tag or using ${ELexpressions}
All you can pass from the client to the server is request parameters - which are always strings.
Draw a picture of where the information is, and the information flows. Very rarely does it go directly from one "form" to another.
Cheers,
evnafets

Retrieving data from database into tabular layout item

Hi..
If the number of product_id is 1; I can retrieve data from the database into tabular layout item.However, if the number of product_id is more than 1 error message is shown.
Here is my code:
select product_id
into : PRODUCTS. ID --Tabular layout item
from products
where customer_id=5;
Any suggestions????

It's simpler to do so:
insert that code in a post-query trigger at block level (block where is multi-item)
You will see after execute-query, your item will be populated.
I wrote post-query trigger no post-quert

Error retrieving data from database

my problem is i cant connect my eclipse to database
it display this error
Error parsing data org.json.JSONException: Value <html><body><h2>Checking of type java.lang.String cannot be converted to JSONObject
my apps can run correctly before...but last night i cant open it when want to retrieve any data from database
can somebody help me?

This doesn't seem to have anything to do with Eclipse, but I'd guess that a server-side error message is being returned a HTML rather than the JSON you expect.

Is there a way to retrieve data from database wihout using JDBC while using JPDK?

Hi,
I want to create a portlet using JPDK with extra render modes and edit/Edit defaults mode too. The detail and show renderer mode jsp's/servlets render data from database. Based on the personalized paramter, the data rendered in detail and show mode will be obtained from database.
The articles in the PDK zip asks not to use JDBC for security vulnerability. Does that mean , I should not use JDBC to connect to db to get data. If not, what should I use ? How do I connect to database ? Is there any class which helps to connect to db without using JDBC ?
thanks,
Mainak

I'm not sure what articles you are refering to, because there is no other way to access a database from a java program. Generally, security related docs tend to be a little paranoid (and so they should be), but you have to balance high security against getting the job done.
Obviously, if using JDBC, you need to be careful about protecting your config files because they will contain connection information.

Failed to retrieve data from database - DataDirect Paradox

Crystal Reports 12.1.0.892
Windows XP SP3
DataDirect ODBC Driver for Paradox 5.30.00.23
Paradox 5 database
When I run the following query against two tables:
SELECT `Ticket1a`.`PatronID`, `PHONELIN`.`PhoneNumber`
FROM `PHONELIN` `PHONELIN` INNER JOIN `Ticket1a` `Ticket1a` ON `PHONELIN`.`PatronID`=`Ticket1a`.`PatronID`
I get the following error:
Failed to retrieve data from the database
Details: 42000: DataDirect ODBC Paradox driver Extra characters at end of query: INNER. Database VendorCode: 3902
The SQL tracing log can be found at http://188.grandtheater.org/sql.log
Can anyone tell me what is going on here and how I can get around it?
TIA

I tried the Add Command option and entered the SQL query as follows:
select ticket1a.patronid, phonelin.phonenumber
from ticket1a ticket1a inner join phonelin phonelin on ticket1a.patronid=phonelin.patronid
and still got the same error as before. Using the following SQL query:
select ticket1a.patronid, phonelin.phonenumber
from ticket1a, phonelin
where ticket1a.patronid = phonelin.patronid
I was able to get results using the DataDirect driver.
If I use the Microsoft Paradox driver (which is very slow. 15 minutes to run this query) and use the following SQL query:
select ticket1a.patronid, phonelin.phonenumber
from ticket1a ticket1a inner join phonelin phonelin on ticket1a.patronid=phonelin.patronid
I will not get the error and I will get results.
Any reasons why the DataDirect driver is producing errors?
