/** |
|
10
|
|
|
* It's a utility that provides a convenient way to create column schema for use with {@see Schema} for Oracle Server. |
|
11
|
|
|
* |
|
12
|
|
|
* It provides methods for specifying the properties of a column, such as its type, size, default value, and whether it |
|
13
|
|
|
* is nullable or not. It also provides a method for creating a column schema based on the specified properties. |
|
14
|
|
|
* |
|
15
|
|
|
* For example, the following code creates a column schema for an integer column: |
|
16
|
|
|
* |
|
17
|
|
|
* ```php |
|
18
|
|
|
* $column = (new Column(SchemaInterface::TYPE_INTEGER))->notNull()->defaultValue(0); |
|
19
|
|
|
* ``` |
|
20
|
|
|
* |
|
21
|
|
|
* Provides a fluent interface, which means that the methods can be chained together to create a column schema with |
|
22
|
|
|
* many properties in a single line of code. |
