Retrieve and display info from 3 tables

Been struggling with this for some days now. Setting up a calendar with football fixtures. For some reason, the team names do not appear in the table and this is really killing me. I thought I knew something about sql and php, guess not.
So for building up this page, I use 3 tables, Season, Teams & Calendar containing a.o. these columns. The first table, season, has only 1 record/row, being the season that's up, in this case 2010-2011:
Season
id (primary key - AI)
current
Teams
id (primary key - AI)
season
leagueid
teamid (unique value)
teamname
Calendar
id (primary key - AI)
season
leagueid
hometeamid
awayteamid
So, what the query should look like is, based on that 1 record from the table season, it has to select all games from the table calendar, selecting all the columns as displayed above. Now that's the easiest part, the hardest part is, replacing the hometeamid AND awayteamid by their names from the teams table. The teamid you see in the table teams is also used in the table calender. Below some basic input from the tables in question, to get a better feel of it:
Season
1
2010-2011
Teams
ID
Season
League ID
Team ID
Team Name
1
2010-2011
u12
1245-u12aa
Team XYZ
2
2010-2011
u8a
9521-u8a
Team ABC
3
2010-2011
u12
1245-u12a
Team HFH
Calendar
ID
Season
League ID
Hometeam ID
Awayteam ID
1
2010-2011
u12
1245-u12aa
5874-u12a
2
2010-2011
u12
9521-u12ab
7436-u12ab

So far you have 4 tables, so the links between the 4 tables is:
1)id from season table(parent) is linked to seasonid from teams table(child)
2)id from season table(parent) is linked to seasonid from calendar table(child)
3)id from league table(parent) is linked to leagueid from teams table(child)
So the joins between them are:
JOIN1: season.id=teams.seasonid
JOIN2: season.id=calendar.seasonid
JOIN3: league.id=teams.leagueid
To extract from multiple tables, SQL query would be as follows:(criteria 1 is optional)
SELECT * FROM teams,season,league,calendar
WHERE [CRITERIA 1] AND JOIN1 AND JOIN2 AND JOIN3
To create relational tables, change all the tables ENGINE=INNODB
then
ALTER TABLE foreign table name ADD FOREIGN KEY(' insert foreign key') REFERENCES(' insert database.primary table.primary key ')
ON DELETE CASCADE ON UPDATE CASCADE

How to retrieve and display image from database in a web page

Hi all;
I have been trying this for some time now. I have found some tutorials so far but none of them addresses my concern. Here it is:
I have built a web application that can connect to an Oracle DB.
I have a table called "employee", where I record any employee details, among which the employee picture. I stored the pictures and the finger prints using "Oracle sql developper" as blob type.
How can i retrieve and view all these information when i run the application?
I can easily retrieve all other types of value, but the image(BLOB type) has been a nightmare for me.
HELP PLEASE.

I believe your Binary Large Obejct will come back as an array of int, and you'll need to use BufferedImage it's associated API to get it to a viewable image configuration.I don't think BufferedImage immediately solves the problem -- this is a web app, so I assume the image will be displayed using the HTML IMG tag.
Solution: google. There are many example of how to do this. For example, any book on servlets will have an example of dishing up a dynamic image.

Retrieving and downloading info from the cloud

How can I download items from the iCloud such as contacts, calendar, and notes?

If you mean on your iPad, go to Settings>iCloud, sign into your account, then turn on the data sets you want to download (such as contacts, calendars and notes). If you mean you want to download a copy so they can be archived, see http://support.apple.com/kb/ht4910.

Help, how to open and display blobs from tables

Dear all,
I am trying to store ms-word files on a table using a blob column.
Does anyone how to open the files and display them from a form using 9iAS?
Thank you.
Carlos.

And there may be, but you won't likely find that here. Do some time searching Google and maybe you'll find code that someone was nice enough to make freely available, although I wouldn't count on it. Were i a programmer and took the time to read those docs and write the code, I'd want to be paid for my time. But there are a lot of programmers who swear by freeware! You may get lucky.

Create a table with a Long RAW Datatype column for storing the Image Column Data.
Create the form based on the table , which by defaults the column with LONG RAW atatype to a Image Item.
You can use Forms Built in function READ_IMAGE_FILE to read a Image file stored on the file system in to the image item.
A save on the form saves the image in the Image item in the long raw column.

Help with displaying info from database+asp

How can I display info from a database so that it is
formatted into rows in a table
here is an example of what I would like
http://www.westerveltcollege.com/new/programs/bus_admin_computers.html
(it is the section that show the course content)
I know it has been code into the table but how to do this
dymanically
hope that makes sense to someone ;)

To do it properly you would set up two tables. The first
would contain the
topics and be something like this
topicID
topicName
Then you would have a second table that would hold the
content like this
contentID
contentName
topicID
The last field links this table to the topic.
To display them you would link the topics into a master list,
and then pass
the topicID to the page displaying the content and use the
topicID as a
filter on the content table.

How to acquire and display data from labview to excel simultaneously

hello,
I am using the NI-DAQ to measure the falling edges of a clock and display them into a table. What I need is to display these data in a table in excel while the program is running. In addition, when I receive a pulse from an external clock, for which I have created a digital channell, the data must be logged in a different column. In other words, every time I receive a pulse the data must be stored in the adjacent column in excel.

Hello Evangelos,
As far as I know and have experienced, it is not possible to access a spreadsheet file (or any file, for that matter) by two programs at the same time, you will get an error.
Also, a couple of observations on your code:
A constant wired to a case selector of a case structure makes no sense as the false case will never be executed.
Move the DAQmx Read from your Digital Input task into the while loop, as the DAQmx Read will only read once and the wire won’t get information in or out of a while loop as long as the while loop is iterating.

Creating a external content type for Read and Update data from two tables in sqlserver using sharepoint designer

When I try to create an external content type based on a view (AdventureWorks2012.vSalesPerson) - I can display the data in an external list. When I attempt to edit it, I get an error:
External List fails when attached to a SQL view
Sorry, something went wrong
Failed to update a list item for this external list based on the Entity (External Content Type) 'SalesForce' in EntityNamespace 'http://xxxxxxxx'. Details: The query against the database caused an error.
I can edit the view in SQL Manager, so it seems strange that it fails.
Any advice would be greatly GREATLY appreciated.

Store and Display Image from Database

Now that MySQL is working (woo hoo!) with JSC, I have a couple of questions for any experts out there...
1. How would I perform an image or other file upload from a browser?
2. How would I retrieve and display an image from a db on a jsp page?
Thanks for any help.

Craig, I think I have a simpler way to load an image on the page, although for the time being I'm not retrieving from a database, but from the file system. The problem is that I'm not getting the pages to load continuously with new images. At some point it apears that the session gets clogges and can not load new pictures. I'll try to include the page bean code just below. This time I'm not adding the "code" tags because I haven't being successful with that. If you have problems , please, contact me at [email protected].
The core of the code is in a couple of button_action methods.
If you need, I can give access to the http server where this is running.

Create a procedure which requires displaying information from two tables

What if we want to create a procedure which requires displaying information from two tables. In this situation,
I need to display all the details of an employee from an 'emp' table based on the deptno. and also their salary information which is
stored in "Salgrade" Table. Is the use of "And" the correct way of using it?
Do I need to declare all the attributes before begin or I can just access them directly? Thanks
Create Procedure findDept
( I_deptno IN number
) As
Begin
Select Ename, Job, MGR, Hiredate, Sal, Comm, Dept_no from emp and exp, grade , location from salgrade where dept_no
= I_Deptno;
Exception
When NO_Data_Found then
DBMS_Output.Put_Line(' Department not found"|| I_deptno);
End findDept;

Hi,
Besides Qwerty's remark, you've also got a quoting error:
Change
DBMS_Output.Put_Line(' Department not found"|| I_deptno);
{code}
into
{code}
dbms_output.put_line(' Department not found: '|| i_deptno);
{code}
Which leads to the question:
What do you want to do when a record is found?
Display it?

UPDATING A TABLE WITH SAME INFO FROM ANOTHER TABLE ON THE SAME DB

0down votefavorite
I am trying to update a table with info from another table on the same db with same table name. I just want the info to be the same , no primary key or constraint involve just a straight replacement of records and I keep getting errors WITH THE TABLE not
being recignize. below is my query:
UPDATE
VNDFIL
SET EOBTYP
= VNDFIL.EOBTYP,
EDI_X12_835_VERSION = VNDFIL.EDI_X12_835_VERSION
FROM
AGERECOVERY
WHERE
VNDFIL.EOBTYP
= VNDFIL.EOBTYP
AND
VNDFIL
.EDI_X12_835_VERSION
= VNDFIL.EDI_X12_835_VERSION

Hi rotary,
If those two same named tables are in the same database then they have to be in different schemas. If you mean they are in the same server instance, then they may be in different databases, besides the "table not being recognized" error,
anyway you should use the fully qualified table names, that is database.Schema.Table(If across instances, ServerName should be prefixed) to avoid the table unrecognized error.
Using Identifiers As Object Names
With the fully qualified names, your update statement can be like below.
UPDATE
db1.schema1.VNDFIL
SET EOBTYP = srcTbl.EOBTYP, EDI_X12_835_VERSION = srcTbl.EDI_X12_835_VERSION
FROM
db1.schema2.VNDFIL srcTbl
WHERE
db1.schema1.VNDFIL.EOBTYP = srcTbl.VNDFIL.EOBTYP AND
db1.schema1.VNDFIL.EDI_X12_835_VERSION = srcTbl.VNDFIL.EDI_X12_835_VERSION
If you have any question, feel free to let me know.

Retrieving multiple rows selected from a table

I want to retrieve selected multiple rows from a table and pass it to other views. Does anyone know how to implement this

You could try a simple example:
Create a context node "Rows" with a string attribute "Text". Create some node elements in wdDoInit().
Create an action "ShowSelectedRowIndices" and implement the event handler as follows:
//@@begin javadoc:onActionShowSelectedRowIndices(ServerEvent)
/** Declared validating event handler. */
//@@end
public void onActionShowSelectedRowIndices(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionShowSelectedRowIndices(ServerEvent)
    StringBuffer msg = new StringBuffer("Multi-selected rows:");
    for (int i = 0; i < wdContext.nodeRows().size(); ++i)
      if (wdContext.nodeRows().isMultiSelected(i))
        msg.append(" ").append(i);
    wdComponentAPI.getMessageManager().reportSuccess(msg.toString());
    //@@end
When executing the action (e.g. with a button) you will see the selected indices in the message area.

Retrieve specific range data from oracle table

Hi, Dear friends,
I want to retrieve all the data from oracle table and then save them to mysql table using JDBC ResultSet. The problem is that some oracle table is too big, if I retrieve all of them to memory at a once time using excuteQuery, the program will become no response out of memory limitation. So my question is if I can retrieve just specific range data once a time. I can¡¯t find this function through JDBC API. Also, I don¡¯t want to use the specific sql sentence, for example ¡°select ¡ from¡ where someid>¡ and someid<¡¡±, because there are many different tables, I want to transfer them automatically. So I can¡¯t construct such sql sentence in advance. Does anyone know if oracle JDBC driver provide such kind of function or does there any other way?
Any suggestion will be greatly appreciated!
Sammy

Dear Justin,
thank you so much for your prompt reply!
as your suggestion, I do check the performance while my program is running, after the program become nearly no response, I found the memory usage is nearly 100%, while disk usage and process usage is pretty low. that's the reason why I guess maybe the memory limitation, but the strange thing is that no any error reported by JBuilder, it just nearly no response and don't transfer any data any more. my os is windows xp, the version of JBuilder is 7. my main memory is 768M. just as you said, the total 6,000 records in not very large, just no more than 400K. another strange thing is that why my program works well when there is little data records in the table.
the big picture of my program is first I retrieve oracle table metadata, according to this information, I construct DDL sql words and then create the corresponding table in mysql database. this part works well. in order to save your time, I will not paste the code here. then there is a method to transfer oracle data to mysql table, whenever creating the mysql table, then I will call this method to transfer datat to it. the following is the code of this method, I am very sorry to take your time. please read it when you are available.
thank you very much!!
Sammy
