ZXing provides Java source code that reads most any common format (UPC, EAN, QR codes, etc.). It provides source to a complete Android and J2ME app, and ... Null values in SQL often cause trouble. You must be aware of their existence in the database and their odds of being generated by Oracle in (intermediate) results, and you must continuously ask yourself how you want them to be treated in the processing of your SQL statements. Otherwise, the correctness of your queries will be debatable, to say the least. You have already seen that null values in expressions generally cause those expressions to produce a null value. In the next chapter, you will learn how the various SQL functions handle null values. It is obvious that there are many pitfalls in the area of missing information. It may be possible to circumvent at least some of these problems by properly designing your databases. In one of his books, Ted Codd, the inventor of the relational model, even proposed introducing two types of null values: applicable and inapplicable. This would imply the need for a four-valued logic (see Ted Codd, 1990). java barcode reader library BarCode Reader Application - Using ZXing Library - EDUmobile.ORG

Edits are automatically saved to Concordance in response to a user navigating to another record, closing the database, or activating another Concordance tool, such as Form Search. There s no Save button, per se, as it isn t needed. When Edit view is activated, a series of buttons is made visible on the bottom of the Concordance screen. Record navigation buttons, as described in the Browse View section earlier in this chapter, allow you to advance or retreat through records. The Go To button is available as well. Other buttons useful during Edit view are the following: : Allows you to create a new record in Concordance, duplicating values from Ditto fields that you select. Clicking this button opens the Duplicate tool a dialog that displays all fields in the database and offers other options (see Figure 8-20). To select fields to be duplicated, click the field name, highlighting it. To select two or more fields, press the Ctrl key, and then click field names while the Ctrl key is depressed. When you select the Append new radio button, a new record is created, with field values duplicated from the values of the record that was active when the Duplicate tool was opened. If you select the Copy previous radio button, values will be copied from the previous record. If you select the Copy from another radio button, you must specify the numerical position of an existing record that will provide data for the new record. sub _build_translators { my ($self) =@_; return { LOLCAT => LolCatalyst::Lite::Translator::LOLCAT->new }; } Since we currently have only a single translator, we can hard-code the hashref construction to get started. sub translate { my ($self, $text) = @_; $self->translate_to($self->default_target, $text); } Tip If you are interested in more details about the trouble of null values (or other theoretical information about relational databases and pitfalls in SQL), the books written by Chris Date are the best starting point for further exploration. In particular, his Selected Writings series is brilliant. Chris Date s ability to write in an understandable, entertaining, and fascinating way about these topics far exceeds others in the field.
