12         my $trans = SQL::Translator->new(
13             from => 'MySQL',            # or your db of choice

DESCRIPTION

27       Creates a graph of a schema using the amazing graphviz (see
28       http://www.graphviz.org/) application (via the GraphViz module).  It's
29       nifty--you should try it!

PRODUCER ARGS

32       All GraphViz constructor attributes are accepted and passed through to
33       "new" in GraphViz. The following defaults are assumed for some
34       attributes:
35
36         layout => 'dot',
37         overlap => 'false',
38
39         node => {
40           shape => 'record',
41           style => 'filled',
42           fillcolor => 'white',
43         },
44
45         # in inches
46         width => 8.5,
47         height => 11,
48
49       See the documentation of "new" in GraphViz for more info on these and
50       other attributes.
51
52       In addition this producer accepts the following arguments:
53
54       ·   skip_tables
55
56           An arrayref or a comma-separated list of table names that should be
57           skipped. Note that a skipped table node may still appear if another
58           table has foreign key constraints pointing to the skipped table. If
59           this happens no table field/index information will be included.
60
61       ·   skip_tables_like
62
63           An arrayref or a comma-separated list of regular expressions
64           matching table names that should be skipped.
65
66       ·   cluster
67
68           Clustering of tables allows you to group and box tables according
69           to function or domain or whatever criteria you choose.  The syntax
70           for clustering tables is:
71
72             cluster => 'cluster1=table1,table2;cluster2=table3,table4'
73
74           Or pass it as an arrayref like so:
75
76             cluster => [ 'cluster1=table1,table2', 'cluster2=table3,table4' ]
77
78           Or like so:
79
80             cluster => [
81               { name => 'cluster1', tables => [ 'table1', 'table2' ] },
82               { name => 'cluster2', tables => [ 'table3', 'table4' ] },
83             ]
84
85       ·   out_file
86
87           The name of the file where the resulting GraphViz output will be
88           written. Alternatively an open filehandle can be supplied. If
89           undefined (the default) - the result is returned as a string.
90
91       ·   output_type (DEFAULT: 'png')
92
93           This determines which output method will be invoked to generate the
94           graph: "png" translates to "as_png", "ps" to "as_ps" and so on.
95
96       ·   fontname
97
98           This sets the global font name (or full path to font file) for
99           node, edge, and graph labels
100
101       ·   fontsize
102
103           This sets the global font size for node and edge labels (note that
104           arbitrarily large sizes may be ignored due to page size or graph
105           size constraints)
106
107       ·   show_fields (DEFAULT: true)
108
109           If set to a true value, the names of the columns in a table will be
110           displayed in each table's node
111
112       ·   show_fk_only
113
114           If set to a true value, only columns which are foreign keys will be
115           displayed in each table's node
116
117       ·   show_datatypes
118
119           If set to a true value, the datatype of each column will be
120           displayed next to each column's name; this option will have no
121           effect if the value of "show_fields" is set to false
122
123       ·   friendly_ints
124
125           If set to a true value, each integer type field will be displayed
126           as a tinyint, smallint, integer or bigint depending on the field's
127           associated size parameter. This only applies for the "integer" type
128           (and not the "int" type, which is always assumed to be a 32-bit
129           integer); this option will have no effect if the value of
130           "show_fields" is set to false
131
132       ·   friendly_ints_extended
133
134           If set to a true value, the friendly ints displayed will take into
135           account the non-standard types, 'tinyint' and 'mediumint' (which,
136           as far as I am aware, is only implemented in MySQL)
137
138       ·   show_sizes
139
140           If set to a true value, the size (in bytes) of each CHAR and
141           VARCHAR column will be displayed in parentheses next to the
142           column's name; this option will have no effect if the value of
143           "show_fields" is set to false
144
145       ·   show_constraints
146
147           If set to a true value, a field's constraints (i.e., its primary-
148           key-ness, its foreign-key-ness and/or its uniqueness) will appear
149           as a comma-separated list in brackets next to the field's name;
150           this option will have no effect if the value of "show_fields" is
151           set to false
152
153       ·   show_indexes
154
155           If set to a true value, each record will also show the indexes set
156           on each table. It describes the index types along with which
157           columns are included in the index.
158
159       ·   show_index_names (DEFAULT: true)
160
161           If "show_indexes" is set to a true value, then the value of this
162           parameter determines whether or not to print names of indexes.  if
163           "show_index_names" is false, then a list of indexed columns will
164           appear below the field list. Otherwise, it will be a list prefixed
165           with the name of each index.
166
167       ·   natural_join
168
169           If set to a true value, "make_natural_joins" in
170           SQL::Translator::Schema will be called before generating the graph.
171
172       ·   join_pk_only
173
174           The value of this option will be passed as the value of the like-
175           named argument to "make_natural_joins" in SQL::Translator::Schema;
176           implies "natural_join => 1"
177
178       ·   skip_fields
179
180           The value of this option will be passed as the value of the like-
181           named argument to "make_natural_joins" in SQL::Translator::Schema;
182           implies "natural_join => 1"
183

192
193           If set to a true value, the graphic will have a background color of
194           'lightgoldenrodyellow'; otherwise the default white background will
195           be used
