7       tables.

SYNOPSIS

10         # e.g. Add timestamp field to all tables.
11         use SQL::Translator;

13         my $sqlt = SQL::Translator->new(
14             from => 'MySQL',
15             to   => 'MySQL',
16             filters => [
17               Globals => {
18                   fields => [
19                       {
20                           name => 'modified'
21                           data_type => 'TIMESTAMP'
22                       }

26                           fields => 'modifed',
27                       },
28                   ]

32                   ]
33               },

DESCRIPTION

39       Adds global fields, indices and constraints to all tables in the
40       schema.  The globals to add can either be defined in the filter args or
41       using a _GLOBAL_ table (see below).
42
43       If a table already contains a field with the same name as a global then
44       it is skipped for that table.
45
46   The _GLOBAL_ Table
47       An alternative to using the args is to add a table called "_GLOBAL_" to
48       the schema and then just use the filter. Any fields and indices defined
49       on this table will be added to all the tables in the schema and the
50       _GLOBAL_ table removed.
51
52       The name of the global can be changed using a "global_table" arg to the
53       filter.

BUGS

59       Will generate duplicate indices if an index already exists on a table
60       the same as one added globally.
61
62       Will generate duplicate constraints if a constraint already exists on a
63       table the same as one added globally.
64

TODO

66       Some extra data values that can be used to control the global addition.
67       e.g.  'skip_global'.
