使用sql server时bug非常多，需要怎么修复？

比如使用模型关联统计的时候会报错：
SQLSTATE[42000]: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]当没有用 EXISTS 引入子查询时，在选择列表中只能指定一个表达式。
我总表的hasMany添加了，明细表的belongsTo也添加了，按着教程的做都报错

• 能自行解决的且代码有优化空间的，可提交PR。
• 自行解决不了的，请补充详细信息（包括但不限于代码和表结构）

先声明，我的环境是：sql server
比如我有2个表：customer，equipment
customer表里面有字段：customer_id（主键），name
equipment表里有字段：equipment_id (主键)，equipment_model，customer_id

然后我生成了2个model：CustomerModel、EquipmentModel
在CustomerModel添加了：
function equipments() {
return $this->hasMany(EquipmentModel::class,'customer_id','customer_id');
}

现在我在customer的controller里面使用
$customer_equipments_count= CustomerModel::withCount('equipments')->select();
这个就直接报错了，错误代码：
[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]当没有用 EXISTS 引入子查询时，在选择列表中只能指定一个表达式。

合成的sql语句为：
SELECT T1.* FROM (SELECT thinkphp., ROW_NUMBER() OVER ( ORDER BY rand()) AS ROW_NUMBER FROM (SELECT ,(SELECT T1. FROM (SELECT thinkphp., ROW_NUMBER() OVER ( ORDER BY rand()) AS ROW_NUMBER FROM (SELECT COUNT(*) AS think_count FROM [d_equipment] [count_table] WHERE ( [count_table].[customer_id] =d_customer.customer_id ) ) AS thinkphp) AS T1) AS [equipments_count] FROM [d_customer] WHERE [customer_id] IN (1,2,3) ) AS thinkphp) AS T1
