将Oracle存储过程转换为SQL Server存储过程

亲爱的各位，有人能帮我转换以下Oracle存储过程吗 到SQL Server版本

您能提供数据进行测试吗？您的数据类型有问题，但似乎是从oracle开始的。你为什么用数字代替日期？这就是数据类型的要点，使用正确的数据类型。oracle中的游标没有sql server那么糟糕，但这里不需要循环和游标。这可以是基于设置的，在oracle中也应该是基于设置的。您可以提供要测试的数据吗？您的数据类型有问题，但似乎是从oracle开始的。你为什么用数字代替日期？这就是数据类型的要点，使用正确的数据类型。oracle中的游标没有sql server那么糟糕，但这里不需要循环和游标。这可以设置为基础，也应该在oracle中设置为基础。
