|
* Represents the metadata of a column in a database table for MSSQL Server. |
|
17
|
|
|
* |
|
18
|
|
|
* It provides information about the column's name, type, size, precision, and other details. |
|

|
|
|
* Is used to store and retrieve metadata about a column in a database table. It's typically used in conjunction with |
|
21
|
|
|
* the {@see TableSchema}, which represents the metadata of a database table as a whole. |
|

* The following code shows how to use: |

|
|
|
* |
|
25
|
|
|
* ```php |
|
26
|
|
|
* use Yiisoft\Db\Mssql\ColumnSchema; |
|
27
|
|
|
* |
|
28
|
|
|
* $column = new ColumnSchema(); |
|
29
|
|
|
* $column->name('id'); |
|
30
|
|
|
* $column->allowNull(false); |
|
31
|
|
|
* $column->dbType('int'); |
|
32

* $column->phpType('integer'); |
|

* $column->type('integer'); |
|

|
|

* $column->defaultValue(0); |
|
35
|
|
|
* $column->autoIncrement(true); |
|
