Import Excel into MySql database....!!!!

Its easy and quick, thought to share it with you all....

Convert Excel into csv file with Save As.
Open the csv file in notepad/wordpad, see the delimeter (should be a comma).
Write the following command in the query browser
LOAD DATA LOCAL INFILE 'D:\\converted_csv.csv' INTO TABLE database.table FIELDS TERMINATED BY ',' ENCLOSED BY ‘”‘ LINES TERMINATED BY '\r\n' (table.field1, table.field2,table.field3...);

If you get any error, probably the single and double qoutes are not correct, sometimes the editor changes the quotes ASCII, better delete the quotes and write again...

TERMINATED BY is the delimeter you use "comma in our case"
LINES TERMINATED BY – new line character, if you do not use \r, the query will insert a new line character in the database.

Hope this helps....

ORA-06502: PL/SQL: numeric or value error: character string buffer too small

This is a common error faced by many of us and some times it takes hours to find what went wrong.

The reason it happens is

1) The size of the Varchar2 parameter, the maximum allowed size of the Varchar2 datatype is 4000, if the input string exceeds that number you will get this error.

2) Or you have defind your parameter of size 10 and trying to write 12 characters.

Workaround - For first reason, there is no way out you can use the Varchar2 datatype, better use CLOB objects.

For second, try to increase the size of the parameter.

Hope this helps.

Thanks

PL SQL query to create a search query.

Hi,

Often we search for a particular value in the user tables of a database, for each table we have to change the query, if not the column name, at least the table name. The good new is, we can avoid doing that. We can write a query which will create a search query as its result records each for a user table in the database.

select 'select * from '||table_name||'
where upper (to_char(&in_column)) = upper (to_char('||'''&in_value'''||'));'
from user_tab_columns
where column_name = upper ('&in_column');

Run tha above query in PL SQL and see the magic.

Hope that helps you.

Thanks..

Website structure does matter.

When you have decided to create a website for your business or say you are a developer and designing a website for your customer, you should always keep in mind that the Web site structure should not be complicated. A website should be well-organized, a well-organized website is one which is easy to understand, navigate and find easily what the visitor is looking for.

The intensionof the article is to make you understand the level of leaves/pages of the website should reside in. A good well organized website makes it easy for you to grow your site logically.

The page (which has the content) of your website must not be more than two level in the depth, that is the required page should not take more than two clicks from the home page. This is very important with regards to Search Engines.

A typical website structure could be as in the picture below.



Tier 1 – The home page

Tier 2 – The team sites/folders/sub sites

Tier 3 – The leaves/pages with contents

Navigate to portal home from Mysite.

We had this problem of having Portal home link (to return to the portal home page) on Mysite of every user during one of our project, what we did was we created a link in SharedServices1 > Personalization site links.

Easy enough to add a link in SharedServices1 > Personalization site links. Except that when you click and return to your Portal, the menu has retained the MySite navigation because the URL contains "?MySiteView=1".The solution (as per link) is to add a # on the end of the URL you enter, this makes the rest of the link an anchor so SP will ignore it and display your normal menu. Thought to share it with you guys.
