+
+ <title>MySQL <literal>.frm</literal> File Format</title>
+
+ <para>
+ Regardless of the storage engine you choose, every MySQL table you
+ create is represented, on disk, by a <filename>.frm</filename>
+ file, which describes the table's format (i.e. the table
+ definition). The file bears the same name as the table, with a
+ <literal>.frm</literal> extension. The <literal>.frm</literal>
+ format is the same on all platforms but in the description of the
+ .frm format that follows, the examples come from tables created
+ under the Linux operating system.
+ </para>
+
+ <para>
+ First, let's create an example table, using the mysql client:
+ </para>
+
+<programlisting>mysql> CREATE TABLE table1 (column1 CHAR(5)) ENGINE=MYISAM COMMENT '*';
+Query OK, 0 rows affected (0.00 sec)</programlisting>
+
+ <para>
+ The <literal>.frm</literal> file associated with table1 can be
+ located in the directory that represents the database (or schema)
+ to which the table belongs. The <literal>datadir</literal>
+ variable contains the name of this directory:
+ </para>
+
+<programlisting>mysql> SHOW VARIABLES LIKE 'datadir';
++---------------+-----------------------+
+| Variable_name | Value |
++---------------+-----------------------+
+| datadir | /usr/local/mysql/var/ |
++---------------+-----------------------+
+1 row in set (0.00 sec)</programlisting>
+
+ <para>
+ The <literal>DATABASE()</literal> function contains the name of
+ the relevant database:
+ </para>
+
+<programlisting>mysql> SELECT DATABASE();
++------------+
+| DATABASE() |
++------------+
+| ff |
++------------+
+1 row in set (0.00 sec)</programlisting>
+
+ <para>
+ Since MySQL stores .frm files in 'datadir/database_name', it's a
+ simple matter to locate table1's .frm file with the above
+ information. With Linux shell, say:
+ </para>
+
+<programlisting>shell> su root
+shell> cd /usr/local/mysql/var/ff
+shell> ls table1.*</programlisting>
+
+ <para>
+ You'll see a response like the following:
+ </para>
+
+<programlisting>shell> su root
+shell> cd /usr/local/mysql/var/ff
+shell> ls table1.*
+ table1.frm table1.MYD table1.MYI
+shell> ls -l table1.*
+-rw-rw---- 1 root root 8566 2006-09-22 11:22 table1.frm
+-rw-rw---- 1 root root 0 2006-09-22 11:22 table1.MYD
+-rw-rw---- 1 root root 1024 2006-09-22 11:22 table1.MYI</programlisting>
+
+ <para>
+ The <literal>.MYD</literal> and <literal>.MYI</literal> files are
+ not our concern here; they are described elsewhere in this MySQL
+ internals manual. To understand the <literal>.frm</literal>
+ format, let's look at table1.frm using a hexadecimal-dump utility;
+ the contents are show below.
+ </para>
+
+<programlisting>shell> hexdump -v -C table1.frm

+
+ <para>
+ The details shown above might change, especially since there is a
+ transition underway from an old ("binary") format to a new ("text
+ based") <literal>.frm</literal> format. You can confirm that the
+ details are correct by comparing this description with the
+ statements in <filename>sql/table.cc</filename>,
+ <literal>create_frm()</literal>. The table below explains the
+ meaning of each byte in the hexadecimal dump shown in Table 1. In
+ Table 2, "Offset" shows the byte position in the file, "Length" is
+ the number of bytes, "Value" is what's in that byte position for
+ that length (remember that storage is "low byte first" so 0010
+ means 1000!), and "Explanation" provides a brief explanation of
+ the contents.

+ <para>
+ In the example output, notice that position 00001010 and following
+ contains the clear text of the <literal>CREATE TABLE ...
+ PARTITION</literal> clause and not just the
+ <literal>MYISAM</literal> engine information, as in
+ <literal>table1</literal>, which shows the <literal>.frm</literal>
+ of a non-partitioned table.
+ </para>
+
+ <para>
+ Finally, <literal>CREATE VIEW</literal> also causes creation of a
+ <literal>.frm</literal> file, but a view <literal>.frm</literal>
+ bears no resemblance to a base table <literal>.frm</literal>; it's
+ purely textual. Here's an example of a <literal>.frm</literal> for
+ a view made with:
+ </para>
+
+<programlisting>mysql> CREATE VIEW v AS SELECT 5";
+Query OK, 0 rows affected (0.00 sec)</programlisting>
+
+ <para>
+ Just looking at the text will tell you what it's about. For
+ example let's do another hexadecimal dump; the contents are shown
+ below.
+ </para>
+
+<programlisting>
