### Ext Column Types
#### Bit
Bit String.
[Doc](https://www.postgresql.org/docs/current/datatype-bit.html).
```php
$table->bit(string $column, int $length = 1);
```
#### Geo Point
Points are the fundamental two-dimensional building block for geometric types.
[Doc](https://www.postgresql.org/docs/current/datatype-geometric.html#id-1.5.7.16.5).
```php
$table->geoPoint(string $column);
```
#### Geo Path
Paths are represented by lists of connected points.
[Doc](https://www.postgresql.org/docs/current/datatype-geometric.html#id-1.5.7.16.9).
```php
$table->geoPoint(string $column);
```
#### IP Network
The IP network datatype stores an IP network in CIDR notation.
[Doc](https://www.postgresql.org/docs/current/datatype-net-types.html).
IPv4 = 7 bytes
IPv6 = 19 bytes
```php
$table->ipNetwork(string $column);
```
#### Ranges
The range data types store a range of values with optional start and end values. They can be used e.g. to describe the
duration a meeting room is booked.
[Doc](https://www.postgresql.org/docs/current/rangetypes.html).
```php
$table->dateRange(string $column);
$table->tsRange(string $column);
$table->timestampRange(string $column);
```
#### UUID
The `primaryUUID` can be used to store UUID-type as primary key.
```php
$table->primaryUUID(); // create PK UUID-column with name `id`
$table->primaryUUID('custom_name'); // create PK UUID-column with name `custom_name`
```
The `generateUUID` can be used to store UUID-type with/without index (or FK).
On a row creating generates a value with `uuid_generate_v4()` by extension `uuid-ossp`.
```php
// create UUID-column with name `id`. Generate UUID-value by DB.
$table->generateUUID();
// create UUID-column with name `cid`. Generate UUID-value by DB.
$table->generateUUID('cid');
// create UUID-column with name `cid`. NOT generate UUID-value by DB. Set `nullable`. Default value: `NULL`.
$table->generateUUID('id', null);
// create UUID-column with name `cid`. NOT generate UUID-value by DB. Set `nullable`. Default value: `NULL`. Create Index by this column.
$table->generateUUID('fk_id', null)->index();
// create UUID-column with name `fk_id`. NOT generate UUID-value by DB.
$table->generateUUID('fk_id', false);
// create UUID-column with name `fk_id`. Generate UUID-value by DB with custom value.
$table->generateUUID('fk_id', fn($column)=>'uuid_generate_v5()');
// create UUID-column with name `fk_id`. Generate UUID-value by DB with custom value.
$table->generateUUID('fk_id', new Expression('uuid_generate_v2()'));
```
#### XML
The xml data type can be used to store an XML document.
[Doc](https://www.postgresql.org/docs/current/datatype-xml.html).
```php
$table->xml(string $column);
```
#### Array of UUID
The array of UUID data type can be used to store an array of IDs (uuid type).
```php
$table->uuidArray(string $column);
```
#### Array of Integer
The array of integer data type can be used to store a list of integers.
```php
$table->intArray(string $column);
```
#### Array of Text
The array of text data type can be used to store a list of string.
```php
$table->textArray(string $column);
```
### Column Options
#### Compression
PostgreSQL 14 introduced the possibility to specify the compression method for toast-able data types. You can choose
between the default method `pglz`, the recently added `lz4` algorithm and the value `default` to use the server default
setting.
[Doc](https://www.postgresql.org/docs/current/storage-toast.html).
```php
$table->string('col')->compression('lz4');
```
### Views
#### Create views
```php
// Facade methods:
Schema::createView('active_users', "SELECT * FROM users WHERE active = 1");
Schema::createView('active_users', "SELECT * FROM users WHERE active = 1", true) ;
Schema::createViewOrReplace('active_users', "SELECT * FROM users WHERE active = 1");
// Schema methods:
use \Php\Support\Laravel\Database\Schema\Postgres\Blueprint;
Schema::create('users', function (Blueprint $table) {
$table
->createView('active_users', "SELECT * FROM users WHERE active = 1")
->materialize();
});
```
#### Dropping views
```php
// Facade methods:
Schema::dropView('active_users');
Schema::dropViewIfExists('active_users');
```
### Indexes
#### Partial indexes
See: https://www.postgresql.org/docs/current/indexes-partial.html
Example:
```php
use \Php\Support\Laravel\Database\Schema\Postgres\Blueprint;
Schema::create('table', static function (Blueprint $table) {
$table->string('code');
$table->softDeletes();
$table
->partial('code')
->whereNull('deleted_at');
});
```
If you want to delete partial index, use this method:
```php
use \Php\Support\Laravel\Database\Schema\Postgres\Blueprint;
Schema::create('table', static function (Blueprint $table) {
$table->dropPartial(['code']);
});
```
#### Unique Partial indexes
Example:
```php
use \Php\Support\Laravel\Database\Schema\Postgres\Blueprint;
Schema::create('table', static function (Blueprint $table) {
$table->string('code');
$table->softDeletes();
$table
->uniquePartial('code')
->whereNull('deleted_at');
});
```
If you want to delete partial unique index, use this method:
```php
use \Php\Support\Laravel\Database\Schema\Postgres\Blueprint;
Schema::create('table', static function (Blueprint $table) {
$table->dropUniquePartial(['code']);
});
```
`$table->dropUnique()` doesn't work for Partial Unique Indexes, because PostgreSQL doesn't define a partial (ie
conditional) UNIQUE constraint. If you try to delete such a Partial Unique Index you will get an error.
```SQL
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;
```
When you create a unique index without conditions, PostgresSQL will create Unique Constraint automatically for you, and
when you try to delete such an index, Constraint will be deleted first, then Unique Index.
### Extended Schema
#### Create like another table
Create a table from a source-table. Creates a structure only.
`includingAll` copies all dependencies from source-table.
Creating will be without a data.
```php
Schema::create('target_table', function (Blueprint $table) {
$table->like('source_table')->includingAll();
$table->ifNotExists();
});
```
#### Create as another table with full data
Copy a table from a source-table. Copy only columns and a data. Without indexes and so on...
```php
Schema::create('target_table', function (Blueprint $table) {
$table->fromTable('source_table');
});
```
#### Create as another table with data from select query
Create a table from a select query. Copy only columns and a data. Without indexes and so on...
```php
Schema::create('target_table', function (Blueprint $table) {
$table->fromSelect('select id, name from source_table');
});
// or
Schema::create('target_table', function (Blueprint $table) {
$table->fromSelect(
'select t1.id, t2.enabled, t2.extra from source_table t1 ' .
'join source_table_2 t2 on t1.id = t2.src_id ' .
'where t2.enabled = true'
);
});
// or
$tbl = 'source_table';
Schema::create(
$tbl,
static function (Blueprint $table) {
$table->string('key', 16)->primary();
$table->string('title');
$table->integer('sort')->index();
}
);
// or
Schema::create(self::TGT_TABLE, function (Blueprint $table) use ($tbl) {
Schema::createExtensionIfNotExists('uuid-ossp');
$table->fromSelect(
'select uuid_generate_v4() as id, key, title, sort from ' . $tbl
);
});
// or
Schema::create(self::TGT_TABLE, function (Blueprint $table) use ($tbl) {
Schema::createExtensionIfNotExists('uuid-ossp');
$table->fromSelect(
'select uuid_generate_v4() as id, * ' . $tbl
);
});
```
#### Drop Cascade If Exists
Automatically drop objects that depend on the table (such as views, indexes, seqs), and in turn all objects that depend
on those objects.
```php
Schema::dropIfExistsCascade('table');
```
### Extended Query Builder
#### Update records and return updated records` columns
```php
$list = Model::toBase()->updateAndReturn(['deleted_at' => now()], 'id', 'name');
```
```php
$list = Model::where(['enabled' => true])->updateAndReturn(['enabled' => false], 'id');
```
#### Delete records and return deleted records` columns
```php
$list = Model::toBase()->deleteAndReturn('id', 'name');
```
```php
$list = Model::where(['enabled' => true])->deleteAndReturn('id');
```
### Extensions
#### Create Extensions
The Schema facade supports the creation of extensions with the `createExtension` and `createExtensionIfNotExists`
methods:
```php
Schema::createExtension('uuid-ossp');
Schema::createExtensionIfNotExists('uuid-ossp');
```
#### Dropping Extensions
To remove extensions, you may use the `dropExtensionIfExists` methods provided by the Schema facade:
```php
Schema::dropExtensionIfExists('tablefunc');
```
You may drop many extensions at once by passing multiple extension names:
```php
Schema::dropExtensionIfExists('tablefunc', 'fuzzystrmatch');
```
-----
## Usage
### Simple example
```php
primaryUUID();
$table->generateUUID('id', null);
$table->tsRange('range');
$table->numeric('num');
}
);
```
## Test
```bash
composer test
composer test-cover # with coverage
```
