The SQL::Statement module implements a pure Perl SQL parsing and
|
||
|
|
execution engine. While it by no means implements full ANSI standard,
|
||
|
|
it does support many features including column and table aliases,
|
||
|
|
built-in and user-defined functions, implicit and explicit joins,
|
||
|
|
complex nested search conditions, and other features.
|
||
|
|
|
||
|
|
SQL::Statement is a small embeddable Database Management System
|
||
|
|
(DBMS). This means that it provides all of the services of a simple
|
||
|
|
DBMS except that instead of a persistent storage mechanism, it has
|
||
|
|
two things: 1) an in-memory storage mechanism that allows you to
|
||
|
|
prepare, execute, and fetch from SQL statements using temporary
|
||
|
|
tables and 2) a set of software sockets where any author can plug
|
||
|
|
in any storage mechanism.
|
||
|
|
|
||
|
|
There are three main uses for SQL::Statement. One or another
|
||
|
|
(hopefully not all) may be irrelevant for your needs: 1) to access
|
||
|
|
and manipulate data in CSV, XML, and other formats 2) to build your
|
||
|
|
own DBD for a new data source 3) to parse and examine the structure
|
||
|
|
of SQL statements.
