updateColumn 基本用法

更新成功后，返回影响行数，updateColumn 实际上调用的是 update 方法。

public function testBaseUse(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "UPDATE `test_query` SET `test_query`.`name` = :pdonamedparameter_name WHERE `test_query`.`id` = :test_query_id",
            {
                "pdonamedparameter_name": [
                    "小小小鸟，怎么也飞不高。"
                ],
                "test_query_id": [
                    503
                ]
            },
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->sql()
                ->table('test_query')
                ->where('id', 503)
                ->updateColumn('name', '小小小鸟，怎么也飞不高。')
        )
    );
}

updateColumn 支持表达式

public function testExpression(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "UPDATE `test_query` SET `test_query`.`name` = concat(`test_query`.`value`,`test_query`.`name`) WHERE `test_query`.`id` = :test_query_id",
            {
                "test_query_id": [
                    503
                ]
            },
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->sql()
                ->table('test_query')
                ->where('id', 503)
                ->updateColumn('name', Condition::raw('concat([value],[name])'))
        )
    );
}
