/**
* Encapsulation of SQL text and the environment under which it will executed
* with a JDBC Connection.
* 'SqlInputStream' would be a more precise name, but the content we are
* talking about here is what is colloqially known as the contents of
* "SQL file"s.
*
* The file src/org/hsqldb/sample/SqlFileEmbedder.java
* in the HSQLDB distribution provides an example for using SqlFile to
* execute SQL files directly from your own Java classes.
*
* The complexities of passing userVars and macros maps are to facilitate
* strong scoping (among blocks and nested scripts).
*
* Some implementation comments and variable names use keywords based
* on the following definitions.
* - COMMAND = Statement || SpecialCommand || BufferCommand
*
- Statement = SQL statement like "SQL Statement;"
*
- SpecialCommand = Special Command like "\x arg..."
*
- BufferCommand = Editing/buffer command like ":s/this/that/"
*
*
* When entering SQL statements, you are always "appending" to the
* "immediate" command (not the "buffer", which is a different thing).
* All you can do to the immediate command is append new lines to it,
* execute it, or save it to buffer.
* When you are entering a buffer edit command like ":s/this/that/",
* your immediate command is the buffer-edit-command. The buffer
* is the command string that you are editing.
* The buffer usually contains either an exact copy of the last command
* executed or sent to buffer by entering a blank line,
* but BUFFER commands can change the contents of the buffer.
*
* In general, the special commands mirror those of Postgresql's psql,
* but SqlFile handles command editing very differently than Postgresql
* does, in part because of Java's lack of support for raw tty I/O.
* The \p special command, in particular, is very different from psql's.
*
* Buffer commands are unique to SQLFile. The ":" commands allow
* you to edit the buffer and to execute the buffer.
*
* \d commands are very poorly supported for Mysql because
* (a) Mysql lacks most of the most basic JDBC support elements, and
* the most basic role and schema features, and
* (b) to access the Mysql data dictionary, one must change the database
* instance (to do that would require work to restore the original state
* and could have disastrous effects upon transactions).
*
* The process*() methods, other than processBuffHist() ALWAYS execute
* on "buffer", and expect it to contain the method specific prefix
* (if any).
*
* The input/output Reader/Stream are generally managed by the caller.
* An exception is that the input reader may be closed automatically or on
* demand by the user, since in some cases this class builds the Reader.
* There is no corresponding functionality for output since the user always
* has control over that object (which may be null or System.out).
*
* @see
* The SqlTool chapter of the
* HyperSQL Utilities Guide
* @see org.hsqldb.sample.SqlFileEmbedder
