For quite a few days I was searching for something that gives me the ability to

1. open a link (outside webpage) in a popup window
2. Open HTML controls in popup
3. Can show images in the popup
4. Can show images as a slideshow in a popup
5. Can show inline HTML in a popup
6. Should be sexy, not like the old school HTML popup window

After quite a lot of research and comparisons, I came across ColorBox. It perfectly suits my requirements. Okay lets stop talking and start coding

You can download the project source code from here but read the following steps for making yourself familiar with the code.

1. Go to colorbox webiste http://colorpowered.com/colorbox/
2. Get yourself a little familiar with this beauty by trying a few examples over here
3. The example code contains an HTML file with a single link (<a> tag) in it. When that link is clicked,  www.google.com  opens in the popup window.
4. Other files that the package contains are the css file “colorbox.css” , javascript file “jquery.colorbox.js” and the images folder in the same folder as of the html file.
5. That’s it. Open the html file in a browser and click on the link “Outside Webpage (Iframe)” and a popup appears similar to the following image

   

Lesson: Not having Primary keys is a bad idea

So, now I can not delete each row manually so I had to write a query which could do that for me. Thanks god it saved me a lot of time.

So here goes the query, rather queries for performing the same functionality.

First Method

DELETE FROM department
WHERE rowid not in
(
SELECT MIN(rowid)
FROM department d
GROUP BY D.department_id
)

Second Method

DELETE FROM department A
WHERE ROWID > (
SELECT min(rowid)

FROM department B
WHERE A.department_id = B.department_id);

Third Method

DELETE FROM department A
WHERE EXISTS
(
SELECT ‘x’
FROM department B
WHERE A.department_id = B.department_id
AND B.rowid      > A.rowid);

I hope it helps.

Enjoy…

Ooops, and I didn’t do well in that interview either.LOL

Before showing you the query, first, let me make things more easy for you. Here is the table script for our very simple JOB table.

CREATE TABLE AAMT.JOB
(
JOB_ID       INTEGER,
DESCRIPTION  VARCHAR2(50 BYTE)
);

Done? Lets move on and insert a few records in JOB table.

Insert into JOB   (JOB_ID, DESCRIPTION) Values   (1, ‘Teaching’);
Insert into JOB   (JOB_ID, DESCRIPTION) Values   (2, ‘Programming’);
Insert into JOB   (JOB_ID, DESCRIPTION) Values   (3, ‘Administration’);
Insert into JOB   (JOB_ID, DESCRIPTION) Values   (10, ‘DBA’);
Insert into JOB   (JOB_ID, DESCRIPTION) Values   (5, ‘Pilot’);
Insert into JOB   (JOB_ID, DESCRIPTION) Values   (8, ‘Security’);
COMMIT;

OK, ladies and gentlemen here goes an Oracle query that does the same. Rownum is our thing here, rownum will serve our purpose .I hope it would be helpful for you.

select job_id from
(select rownum r,job_id from job order by job_id desc)
where r=2;

This is another version I found on web

SELECT job_id FROM
(SELECT job_id,row_number() OVER (ORDER BY JOB_ID DESC )r  FROM job)
WHERE r=2;

Both queries return

8

I hope this would help.

Please leave feedback or if you have better solution, please share.

Its almost ready Here is what Ubuntu team has to say

DECLARE
tempvar NUMBER;
BEGIN

DBMS_OUTPUT.PUT_LINE(‘hello world’);
END;

Have a look at the image displayed under. Write the SQL mention above into an SQL editor and press Execute Statement button after selecting the entire sql.

Once you execute the above sql, open the output window to see the output. See the image below.

Syntax

CREATE SEQUENCE sequence_name
MINVALUE VALUE
MAXVALUE VALUE
START WITH VALUE
INCREMENT BY VALUE
CACHE VALUE;

A Demo

CREATE SEQUENCE my_seq
MINVALUE 1
MAXVALUE 999999999999999999999999999
START WITH 1
INCREMENT BY 1
CACHE 20;
– If you don’t provide MAXVALUE its default value is 99999999999999999999999999

Using Sequence

SELECT my_seq.NEXTVAL FROM dual;

NEXTVAL
———-
1

SELECT my_seq.NEXTVAL FROM dual;

NEXTVAL
———-
2

SELECT my_seq.NEXTVAL FROM dual;

NEXTVAL
———-
3

SELECT my_seq.NEXTVAL FROM dual;

NEXTVAL
———-
4

Drop Sequence

DROP sequence my_seq;

Increment/Decrement/Alter/Reset Sequence

Now if I want to reset the sequence to a previous value, lets say my current sequence number is 4 and I want my sequence number back at 1. Here is how you can do that.

ALTER SEQUENCE my_seq INCREMENT BY -3;

SELECT my_seq.NEXTVAL FROM dual;

NEXTVAL

—————-

1

If you accendently decremented it by -4, you may get the following error

ORA-08004: sequence my_seq.NEXTVAL goes below MINVALUE and cannot be instantiated

In that case execute the following statment

ALTER SEQUENCE my_seq INCREMENT BY 4;

SELECT my_seq.NEXTVAL FROM dual;

This may solve your problem

1- Deploy the application in webapps directory directly under tomcat directory.

Put the .war file of project in webapp directory and restart tomcat.

2- You have a working project with correct directory structure anywhere on filesystem and you want to deploy that without moving it to webapps directory.

But I don’t wanna create a war file then putting it in webapps directory and later on whenever I make a change I’ll have to deploy it again.

To overcome this issue do the following

2.1- Go to tomcat directory

2.2- Then go to tomcat_home/conf/Catalina/localhost directory

Note: sometimes Catalina/localhost directory structure does not exit. If this is case then first create Catalina direcoty  and then inside Catalina create localhost directorie.

2.3- Create an xml file. Give it a name. This name will be used to access the application from URL. In my case I name it adbank.xml and in the URL for my application is

http://localhost:8080/adbank

2.4- Add the following line in this xml file

<Context path="/AdBlast" docBase="/home/baig/Workspace-AdBlast/AdBank/webapp/webroot" debug="0" reloadable="true"/>

path: provide any name(I personally don’t know its functionality but the path did not matte for me)

docBase: provide the path to you project. I had a few problems with it, I solved it when I provided the path up to the directory where my project’s WEB-INF directory is placed.

2.4- Restart tomcat

2.4- Access you application with a URL similar to this one

http://localhost:8080/adbank

replace adbank with the name of your xml file.
