DESCRIPTION

22       Creates XML output of a schema, in the flavor of XML used natively by
23       the SQLFairy project (SQL::Translator). This format is detailed here.
24
25       The XML lives in the "http://sqlfairy.sourceforge.net/sqlfairy.xml"
26       namespace.  With a root element of <schema>.
27
28       Objects in the schema are mapped to tags of the same name as the
29       objects class (all lowercase).
30
31       The attributes of the objects (e.g. $field->name) are mapped to
32       attributes of the tag, except for sql, comments and action, which get
33       mapped to child data elements.
34
35       List valued attributes (such as the list of fields in an index) get
36       mapped to comma separated lists of values in the attribute.
37
38       Child objects, such as a tables fields, get mapped to child tags
39       wrapped in a set of container tags using the plural of their contained
40       classes name.
41
42       An objects' extra attribute (a hash of arbitrary data) is mapped to a
43       tag called extra, with the hash of data as attributes, sorted into
44       alphabetical order.
45
46       e.g.
47
48           <schema name="" database=""
49             xmlns="http://sqlfairy.sourceforge.net/sqlfairy.xml">
50
51             <tables>
52               <table name="Story" order="1">
53                 <fields>
54                   <field name="id" data_type="BIGINT" size="20"
55                     is_nullable="0" is_auto_increment="1" is_primary_key="1"
56                     is_foreign_key="0" order="3">
57                     <extra ZEROFILL="1" />
58                     <comments></comments>
59                   </field>
60                   <field name="created" data_type="datetime" size="0"
61                     is_nullable="1" is_auto_increment="0" is_primary_key="0"
62                     is_foreign_key="0" order="1">
63                     <extra />
64                     <comments></comments>
65                   </field>
66                   ...
67                 </fields>
68                 <indices>
69                   <index name="foobar" type="NORMAL" fields="foo,bar" options="" />
70                 </indices>
71               </table>
72             </tables>
73
74             <views>
75               <view name="email_list" fields="email" order="1">
76                 <sql>SELECT email FROM Basic WHERE email IS NOT NULL</sql>
77               </view>
78             </views>
79
80           </schema>

ARGS

87       add_prefix
88           Set to true to use the default namespace prefix of 'sqlf', instead
89           of using the default namespace for
90           "http://sqlfairy.sourceforge.net/sqlfairy.xml namespace"
91
92           e.g.
93
94            <!-- add_prefix=0 -->
95            <field name="foo" />
96
97            <!-- add_prefix=1 -->
98            <sqlf:field name="foo" />
99
100       prefix
101           Set to the namespace prefix you want to use for the
102           "http://sqlfairy.sourceforge.net/sqlfairy.xml namespace"
103
104           e.g.
105
106            <!-- prefix='foo' -->
107            <foo:field name="foo" />
108
109       newlines
110           If true (the default) inserts newlines around the XML, otherwise
111           the schema is written on one line.
112
113       indent
114           When using newlines the number of whitespace characters to use as
115           the indent.  Default is 2, set to 0 to turn off indenting.
116

LEGACY FORMAT

118       The previous version of the SQLFairy XML allowed the attributes of the
119       schema objects to be written as either xml attributes or as data
120       elements, in any combination. The old producer could produce attribute
121       only or data element only versions. While this allowed for lots of
122       flexibility in writing the XML the result is a great many possible XML
123       formats, not so good for DTD writing, XPathing etc! So we have moved to
124       a fixed version described above.
125
126       This version of the producer will now only produce the new style XML.
127       To convert your old format files simply pass them through the
128       translator :)

130        $ sqlt -f XML-SQLFairy -t XML-SQLFairy schema-old.xml > schema-new.xml
