<h2>2.0 The Split Amalgamation</h2>

<p>Developers sometimes experience difficulting debugging the
185,000-line-long amalgamation source file because some debuggers
are only able to handle source code line numbers less than 32,768.
The amalgamation source code runs fine.  One just cannot single-step
through it in a debugger.

<p>To circumvent this limitation, the amalgamation is also available in
a split form, consisting of files "sqlite3-1.c", "sqlite3-2.c", and

<blockquote><pre>
SELECT * FROM dbstat;
</pre></blockquote>

<p>
If a named virtual table that uses the dbstat module is desired,
then the recommanded way to create an instance of the dbstat
virtual table is as follows:

<blockquote><pre>
CREATE VIRTUAL TABLE temp.stat USING dbstat(main);
</pre></blockquote>

<p>

       
       <ul>
         <li> Non-ASCII range characters (i.e. unicode codepoints greater 
              than 127), or 
         <li> One of the 52 upper and lower case ASCII characters, or
         <li> One of the 10 decimal digit ASCII characters, or
         <li> The underscore character (unicode codepoint 96).
         <li> The subsitute character (unicode codepoint 26).
       </ul>

       Strings that include any other characters must be quoted. Characters
       that are not currently allowed in barewords, are not quote characters and
       do not currently serve any special purpose in FTS5 query expressions may
       at some point in the future be allowed in barewords or used to implement
       new query functionality. This means that queries that are currently

<p>The [sqlite3_module.xBestIndex] method in the implementation of this
table checks for equality constraints against the HIDDEN columns, and uses
those as input parameters to determine the range of integer "value" outputs
to generate.  Reasonable defaults are used for any unconstrainted columns.
For example, to list all integers between 5 and 50:

<blockquote><pre>
SELECT value FROM generate_series(5,50);
</pre></blockquote>

<p>The previous query is equivalent to the following:
