- * @deprecated Use the following class for specific type:
- * `StringColumnSchema`, `IntegerColumnSchema`, `BigIntColumnSchema`, `DoubleColumnSchema`, `BooleanColumnSchema`,
- * `BinaryColumnSchema`, `JsonColumnSchema`
- *
- * Represents the metadata of a column in a database table for SQLite Server.
- *
- * It provides information about the column's name, type, size, precision, and other details.
- *
- * It's used to store and retrieve metadata about a column in a database table and is typically used in conjunction with
- * the {@see TableSchema}, which represents the metadata of a database table as a whole.
- *
- * The following code shows how to use:
- *
- * ```php
- * use Yiisoft\Db\Sqlite\ColumnSchema;
- *
- * $column = new ColumnSchema();
- * $column->name('id');
- * $column->allowNull(false);
- * $column->dbType('integer');
- * $column->phpType('integer');
- * $column->type('integer');
- * $column->defaultValue(0);
- * $column->autoIncrement(true);
- * $column->primaryKey(true);
- * ```
