NAME

       SQL::Translator::Schema::Table - SQL::Translator table object

SYNOPSIS

         use SQL::Translator::Schema::Table;
         my $table = SQL::Translator::Schema::Table->new( name => 'foo' );

DESCRIPTION

       "SQL::Translator::Schema::Table" is the table object.

METHODS

   new
       Object constructor.

         my $table  =  SQL::Translator::Schema::Table->new(
             schema => $schema,
             name   => 'foo',
         );

   add_constraint
       Add a constraint to the table.  Returns the newly created
       "SQL::Translator::Schema::Constraint" object.

         my $c1     = $table->add_constraint(
             name   => 'pk',
             type   => PRIMARY_KEY,
             fields => [ 'foo_id' ],
         );

         my $c2 = SQL::Translator::Schema::Constraint->new( name => 'uniq' );
         $c2    = $table->add_constraint( $constraint );

   drop_constraint
       Remove a constraint from the table. Returns the constraint object if the index was found
       and removed, an error otherwise. The single parameter can be either an index name or an
       "SQL::Translator::Schema::Constraint" object.

         $table->drop_constraint('myconstraint');

   add_index
       Add an index to the table.  Returns the newly created "SQL::Translator::Schema::Index"
       object.

         my $i1     = $table->add_index(
             name   => 'name',
             fields => [ 'name' ],
             type   => 'normal',
         );

         my $i2 = SQL::Translator::Schema::Index->new( name => 'id' );
         $i2    = $table->add_index( $index );

   drop_index
       Remove an index from the table. Returns the index object if the index was found and
       removed, an error otherwise. The single parameter can be either an index name of an
       "SQL::Translator::Schema::Index" object.

         $table->drop_index('myindex');

   add_field
       Add an field to the table.  Returns the newly created "SQL::Translator::Schema::Field"
       object.  The "name" parameter is required.  If you try to create a field with the same
       name as an existing field, you will get an error and the field will not be created.

         my $f1        =  $table->add_field(
             name      => 'foo_id',
             data_type => 'integer',
             size      => 11,
         );

         my $f2     =  SQL::Translator::Schema::Field->new(
             name   => 'name',
             table  => $table,
         );
         $f2 = $table->add_field( $field2 ) or die $table->error;

   drop_field
       Remove a field from the table. Returns the field object if the field was found and
       removed, an error otherwise. The single parameter can be either a field name or an
       "SQL::Translator::Schema::Field" object.

         $table->drop_field('myfield');

   comments
       Get or set the comments on a table.  May be called several times to set and it will
       accumulate the comments.  Called in an array context, returns each comment individually;
       called in a scalar context, returns all the comments joined on newlines.

         $table->comments('foo');
         $table->comments('bar');
         print join( ', ', $table->comments ); # prints "foo, bar"

   get_constraints
       Returns all the constraint objects as an array or array reference.

         my @constraints = $table->get_constraints;

   get_indices
       Returns all the index objects as an array or array reference.

         my @indices = $table->get_indices;

   get_field
       Returns a field by the name provided.

         my $field = $table->get_field('foo');

   get_fields
       Returns all the field objects as an array or array reference.

         my @fields = $table->get_fields;

   is_valid
       Determine whether the view is valid or not.

         my $ok = $view->is_valid;

   is_trivial_link
       True if table has no data (non-key) fields and only uses single key joins.

   is_data
       Returns true if the table has some non-key fields.

   can_link
       Determine whether the table can link two arg tables via many-to-many.

         my $ok = $table->can_link($table1,$table2);

   name
       Get or set the table's name.

       Errors ("No table name") if you try to set a blank name.

       If provided an argument, checks the schema object for a table of that name and disallows
       the change if one exists (setting the error to "Can't use table name "%s": table exists").

         my $table_name = $table->name('foo');

   schema
       Get or set the table's schema object.

         my $schema = $table->schema;

   primary_key
       Gets or sets the table's primary key(s).  Takes one or more field names (as a string, list
       or array[ref]) as an argument.  If the field names are present, it will create a new PK if
       none exists, or it will add to the fields of an existing PK (and will unique the field
       names).  Returns the "SQL::Translator::Schema::Constraint" object representing the primary
       key.

       These are equivalent:

         $table->primary_key('id');
         $table->primary_key(['name']);
         $table->primary_key('id','name']);
         $table->primary_key(['id','name']);
         $table->primary_key('id,name');
         $table->primary_key(qw[ id name ]);

         my $pk = $table->primary_key;

   options
       Get or append to the table's options (e.g., table types for MySQL).  Returns an array or
       array reference.

         my @options = $table->options;

   order
       Get or set the table's order.

         my $order = $table->order(3);

   field_names
       Read-only method to return a list or array ref of the field names. Returns undef or an
       empty list if the table has no fields set. Useful if you want to avoid the overload magic
       of the Field objects returned by the get_fields method.

         my @names = $constraint->field_names;

   equals
       Determines if this table is the same as another

         my $isIdentical = $table1->equals( $table2 );

LOOKUP METHODS

       The following are a set of shortcut methods for getting commonly used lists of fields and
       constraints. They all return lists or array refs of Field or Constraint objects.

       pkey_fields
           The primary key fields.

       fkey_fields
           All foreign key fields.

       nonpkey_fields
           All the fields except the primary key.

       data_fields
           All non key fields.

       unique_fields
           All fields with unique constraints.

       unique_constraints
           All this tables unique constraints.

       fkey_constraints
           All this tables foreign key constraints. (See primary_key method to get the primary
           key constraint)
