On lines 69 through 83, I ve recoded the detection block to retrieve the primary key value for a row with duplicate values. If a duplicate row exists, variable n_id, initially NULL, will be set to the value of the primary key. Otherwise, if a duplicate row does not exist, a NO_DATA_FOUND exception will be raised. In turn, the exception will be handled by the WHEN NO_DATA_FOUND clause in the enclosing PL/SQL block s exception-handling section. There, in the EXCEPTION clause, I set the value of variable n_id to NULL, to flag that I did not find a duplicate. I actually don t need to set it to NULL, because it remained NULL when the exception was raised. But the Oracle PL/SQL documentation does not explicitly guarantee this behavior, so I set it to NULL. Also, on line 86, now I use the n_id variable to determine if I found a duplicate row. If n_id is NULL, I insert the row. Otherwise, on lines 143 through 154, I update the duplicate row with the worker_type_id value. So if this was a better tactic, what s best Before I answer that question, let s first digress a moment so I can finally explain the syntax of all those IF statements I ve been using all along!

In some applications, however, you don t get the answer right away; you have to try several alternatives. And not only do you have to try several alternatives on one level, but on every level in your recursion. To draw a parallel from real life, imagine that you have an important meeting to go to. You re not sure where it is, but you have two doors in front of you, and the meeting room has to be behind one of them. You choose the left, and step through. There you face another two doors. You choose the left, but it turns out to be wrong. So you backtrack, and choose the right door, which also turns out to be wrong (excuse the pun). So, you backtrack again, to the point where you started, ready to try the right door there. This strategy of backtracking is useful for solving problems that require you try every combination until you find a solution. Such problems are solved like this: # Pseudocode for each possibility at level 1: for each possibility at level 2: ... for each possibility at level n: is it viable To implement this directly with for loops, you have to know how many levels you ll encounter. If that is not possible, you use recursion.

Spring is primarily known as a Dependency Injection container Dependency Injection is the more appropriate term coined by Martin Fowler, Rod Johnson, and the PicoContainer team in late 2003 for what was once known as Inversion of Control An alternative view is that DI is a strategy or flavor of IoC Most explanations of DI also referred to it as the Hollywood Principle: Don t call us, we ll call you Early in my forays into DI containers and the Spring Framework, I found some of the explanations of IoC/DI overly complex The best explanation I can give for DI is that it is a technique by which you externalize the choice of which implementation of a given interface you ll use at runtime In Spring, a system is designed using interfaces, and the Spring framework plugs or injects the right implementations at runtime.

You should (must, in my opinion) create a unique index on each table s primary key column(s) you know, the one that uniquely identifies entries in the table. In our author table, that column is id. However, we will create a unique index on the id column when we talk about constraints in the next section. (It s a kind of the chicken vs. the egg story here which comes first ) Instead, let s create a unique index on the name, birth_date, and gender columns of the author table. Listing 1-3 shows our example. Listing 1-3. DDL for Creating an Index on the Author Table, author_uk1.ndx. 1 2 3 4 5 CREATE UNIQUE INDEX author_uk1 on author ( name, birth_date, gender ); The syntax for the CREATE INDEX statement is as follows: CREATE [UNIQUE] INDEX <index_name> on <table_name> ( <column_name_1>, <column_name_2>, <column_name_N> ); where <index_name> is the name of the index, <table_name> is the name of the table, and <column_name> is the name of a column. The keyword UNIQUE is optional, as denoted by the brackets ([ ]) around it. It just means that the database must check to make sure that the column s combination of the values is unique within the table. Unique indexes are old-fashioned; now it s more common to see a unique constraint, which I ll discuss shortly. But unique indexes are still useful.
