Using style.display instead of style.visibility

Hello,

HTML-CSS-JavaScript combination is little bit tricky to non-web developers.

There are few UIs which seems to be inconsistent as we are using JavaScript to enable/disable the HTML Components.

And it takes time to find out and align all the forms.

If you are using any JavaScript and CSS combination to hide/show any components, below information may save your time. 

To maintain proper alignment of whole HTML and its elements, please use following:

Element Property	Value
style.display	'none' (To hide element)
style.display	'' (Empty string to show element)

Please try to avoid using style.display='block' and style.visibility='hidden'/'visible'/'inline' as it is affecting the CSS applied.

Cheers and Enjoy Scripting!

Dropping all DB tables, views, indexes, sequences in one query.

Most of the time one faces the issues like one need to delete all the tables, views, indexes or sequences in the database.
So following the query which generates DROP statements for all the components present in the Oracle database:

SELECT 'DROP TABLE ' || table_name || ';' AS statement FROM user_tables
Union
SELECT 'DROP VIEW ' || view_name || ';' AS statement from user_views
Union
SELECT 'DROP INDEX ' || index_name || ';' AS statement from user_indexes
Union
SELECT 'DROP SEQUENCE ' || sequence_name || ';' AS statement from user_sequences
Union
SELECT 'DROP SYNONYM ' || SYNONYM_name || ';' AS statement from user_SYNONYMs;

Cheers :)
