/**
|
|
* SchemaBuilderTrait contains shortcut methods to create instances of [[ColumnSchemaBuilder]].
|
|
*
|
|
* These can be used in database migrations to define database schema types using a PHP interface.
|
|
* This is useful to define a schema in a DBMS independent way so that the application may run on
|
|
* different DBMS the same way.
|
|
*
|
|
* For example you may use the following code inside your migration files:
|
|
*
|
|
* ```php
|
|
* $this->createTable('example_table', [
|
|
* 'id' => $this->primaryKey(),
|
|
* 'name' => $this->string(64)->notNull(),
|
|
* 'type' => $this->integer()->notNull()->defaultValue(10),
|
|
* 'description' => $this->text(),
|
|
* 'rule_name' => $this->string(64),
|
|
* 'data' => $this->text(),
|
|
* 'created_at' => $this->datetime()->notNull(),
|
|
* 'updated_at' => $this->datetime(),
|
|
* ]);
|
|
* ```
