PL/SQL Parameter Types Interesting Facts

A parameter is the value that is used in PL/SQL subprograms(procedures,functions), calling programs(could be anonymous PL/SQL blocks, another subprogram,simple EXECUTE procedure_name(parameter),EXECUTE function_name(parameter)). A parameter in calling function/procedure and called program can be any one of the following three types :
1) IN Parameter – It is passed as a read only value from calling program to called program. If we try to modify this IN parameter value in procedures being called, it gives a compile time error
2) OUT Parameter – OUT parameter is the value passed from calling program. It is modified and given back as output to calling program. We can display the value of OUT parameter using DBMS_OUTPUT.PUT_LINE, iSQL*PLUS host variables also called as global variables(in oracle 11g isql*plus is no longer available), using VARIABLE variable name datatype; EXECUTE procedure_name(parameter);PRINT variable name. The variable name is the OUT parameter value returned and displayed in host environment. We can also use this inside oracle forms, reports, java and c applications
3) IN OUT Parameter – It is both value passed into program, variable returned after processing. This is a common type used in most reporting systems where we need to format the output display. A very good example is phone number which when passed as raw value is say 9874563789. After making changes, the output is going to be say 987-456-3789

Oracle Table SET UNUSED Column

We can set a column in a table as UNUSED. When we specify this clause the column becomes invisible and inaccessible. It is equivalent to dropped column. This column can be dropped at a later time when there is less resource consumption.We’ve seen that it is not possible to use SET UNUSED clause with the SYS tables
Now we demonstrate the usage of SET UNUSED as a normal user(schema user) :
SQL> connect temp/temp
Connected.
SQL> desc test;
Name                                      Null?    Type
—————————————– ——– ————————
ID                                        NOT NULL NUMBER(38)
NAME                                               VARCHAR2(10)

SQL> insert into test values(1,’info’);
1 row created.
SQL> insert into test values(2,’new’);
1 row created.
SQL> alter table test set unused (id);
Table altered.
SQL> desc test;
Name                                      Null?    Type
—————————————– ——– ————————–
NAME                                               VARCHAR2(10)
DROP UNUSED Column Oracle Table:
If a column in a database table is set as UNUSED it is essential to drop it at a later point of time. This can be done as a bulk UNUSED column drop. It is simple to specify DROP UNUSED COLUMNS clause along with ALTER TABLE. Here is how we go about it :
SQL> alter table test drop unused columns;
Table altered.

Oracle timbo internationalization

Timbo is an open source project undertaken by Oracle Corporation.It supports internationalization.
Timbo is a message catalog library. It is a simple hashed database of message indexes.The message sources are XML specified by timbo.dtd.
Timbo Tools :
mktimbo – creates a library from XML source.
mktimbolate – creates and merges language-specific sources from the main source file.
timboget – queries message libraries from the command line.
po2timbodoes – a simple translation of the English source to the initial englishTimbo file.
The tools have dependancies on Glib 2 and libxml 2. po2timbo depends onPerl. If we only wish to build the library, specify –disable-toolsas an argument to configure.
