a way to implement 'select any' or 'select one' condition

For the web development, usually, there will be a condition to let user to select the opition, e.g.
option '1': case when the variable is 1
option '2': case when the variable is 2
option '3': case when the variable is 'any' - including 1,2 and others

and in the backside,the sql could be
....  and regexp_like(DR.RESET_TYPE,NVL(:RESET_TYPE,'[12]'),'i');

Although this sql runs perfect as I imaged, our DBA is not happy with it. Because in that situation, he think  adding filter ' and regexp_like(DR.RESET_TYPE,NVL(:RESET_TYPE,'[12]'),'i');'.  is just wasting the oracle resource.

So, What shall I do?
Here is the solution,
replacing .  and regexp_like(DR.RESET_TYPE,NVL(:RESET_TYPE,'[12]'),'i'); with:

... AND (:RESET_TYPE IS NULL OR DR.RESET_TYPE = :RESET_TYPE);

which means when user select 'any' , the value of parameter reset_type  will be null ,so oracle
won't execute the filter 'DR.RESET_TYPE = :RESET_TYPE)' .

Stretch a row if data overflows in jasper reports

It is very common that some columns of the report need to stretch to show all the content in that column. But  if you just specify the property " stretch with overflow' to that column(we called text field in jasper report world) , it will just stretch that column and won't change other columns, so the row could be ridiculous. Haven't find the solution from internet yet. So I just review the properties in iReport one by one and find two useful properties(the bold highlighted in example below) which resolve the problems.   example:
<band height="20" splitType="Stretch"> <textField isStretchWithOverflow="true" pattern="" isBlankWhenNull="true"> <reportElement stretchType="RelativeToTallestObject" mode="Opaque" x="192" y="0" width="183" height="20"/> <box leftPadding="2"> <pen lineWidth="0.25"/> …

Spring - Operations with jdbcTemplate

This class manages all the database communication and exception handling using a java.sql.Connection that is obtained from the provided DataSource. JdbcTemplate is a stateless and threadsafe class and you can safely instantiate a single instance to be used for each DAO.


Use of Callback Methods
JdbcTemplate is based on a template style of programming common to many other parts of Spring. Some method calls are handled entirely by the JdbcTemplate, while others require the calling class to provide callback methods that contain the implementation for parts of the JDBC workflow. This is another form of Inversion of Control. Your application code hands over the responsibility of managing the database access to the template class. The template class in turn calls back to your application code when it needs some detail processing filled in. These callback methods are allowed to throw a java.sql.SQLException, since the framework will be able to catch this exception and use its built-in excepti…
