<blockquote><pre>
SELECT sql FROM sqlite_master
WHERE tbl_name LIKE '%s' AND type!='meta'
ORDER BY type DESC, name
</pre></blockquote>

<p>The <b>%s</b> in the query above is replaced by the argument
to ".schema", of course.</p>
to ".schema", of course.  Notice that the argument to the ".schema"
command appears to the right of an SQL LIKE operator.  So you can
use wildcards in the name of the table.  For example, to get the
schema for all tables whose names contain the character string
"abc" you could enter:</p>}

Code {
sqlite> (((.schema %abc%)))
}

puts {
<p>
Along these same lines,
the ".table" command also accepts a pattern as its first argument.
If you give an argument to the .table command, a "%" is both
appended and prepended and a LIKE clause is added to the query.
This allows you to list only those tables that match a particular
pattern.</p>

<h2>Converting An Entire Database To An ASCII Text File</h2>

<p>Use the ".dump" command to convert the entire contents of a
database into a single ASCII text file.  This file can be converted
back into a database by piping it back into <b>sqlite</b>.</p>
