Features

Extended table creation

Schema::create('table', function (Blueprint $table) {
    $table->like('other_table')->includingAll(); 
    $table->ifNotExists();
});

Extended Schema USING

Schema::create('table', function (Blueprint $table) {
    $table->integer('number');
});

//modifications with data...

Schema::table('table', function (Blueprint $table) {
    $table
        ->string('number')
        ->using("('[' || number || ']')::character varying")
        ->change();
});

Create views

// Facade methods:
Schema::createView('active_users', "SELECT * FROM users WHERE active = 1");
Schema::dropView('active_users')

// Schema methods:
Schema::create('users', function (Blueprint $table) {
    $table
        ->createView('active_users', "SELECT * FROM users WHERE active = 1")
        ->materialize();
});

Get foreign keys

// Facade methods:
/** @var ForeignKeyDefinition[] $fks */
$fks = Schema::getForeignKeys('some_table');

foreach ($fks as $fk) {
    // $fk->source_column_name
    // $fk->target_table_name
    // $fk->target_column_name
}

Extended unique indexes creation

Schema::create('table', function (Blueprint $table) {
    $table->string('code'); 
    $table->softDeletes();
    $table->uniquePartial('code')->whereNull('deleted_at');
});

Schema::create('table', function (Blueprint $table) {
    $table->dropUniquePartial(['code']);
});

CREATE UNIQUE INDEX CONCURRENTLY examples_new_col_idx ON examples (new_col);
ALTER TABLE examples
    ADD CONSTRAINT examples_unique_constraint USING INDEX examples_new_col_idx;

Exclude constraints creation

Schema::create('table', function (Blueprint $table) {
    $table->integer('type_id'); 
    $table->date('date_start'); 
    $table->date('date_end'); 
    $table->softDeletes();
    $table
        ->exclude(['date_start', 'date_end'])
        ->using('type_id', '=')
        ->using('daterange(date_start, date_end)', '&&')
        ->method('gist')
        ->with('some_arg', 1)
        ->with('any_arg', 'some_value')
        ->whereNull('deleted_at');
});

ALTER TABLE test_table
    ADD CONSTRAINT test_table_date_start_date_end_excl
        EXCLUDE USING gist (type_id WITH =, daterange(date_start, date_end) WITH &&)
        WITH (some_arg = 1, any_arg = 'some_value')
        WHERE ("deleted_at" is null)

Check constraints creation

Schema::create('table', function (Blueprint $table) {
    $table->integer('type_id'); 
    $table->date('date_start'); 
    $table->date('date_end'); 
    $table
        ->check(['date_start', 'date_end'])
        ->whereColumn('date_end', '>', 'date_start')
        ->whereIn('type_id', [1, 2, 3]);
});

ALTER TABLE test_table
    ADD CONSTRAINT test_table_date_start_date_end_chk
        CHECK ("date_end" > "date_start" AND "type_id" IN [1, 2, 3])

Partitions

Schema::table('table', function (Blueprint $table) {
    $table->attachPartition('partition')->range([
        'from' => now()->startOfDay(), // Carbon will be converted to date time string
        'to' => now()->tomorrow(),
    ]);
});

Check existing index

Schema::table('some_table', function (Blueprint $table) {
   // check unique index exists on column
   if ($table->hasIndex(['column'], true)) {
      $table->dropUnique(['column']);
   }
   $table->uniquePartial('column')->whereNull('deleted_at');
});

Numeric column type

Schema::table('some_table', function (Blueprint $table) {
   $table->numeric('column_with_variable_precision');
   $table->numeric('column_with_defined_precision', 8);
   $table->numeric('column_with_defined_precision_and_scale', 8, 2);
});
