Oracle的RETURNING INTO:使用SQL Server的等效变量

Question

我有以下适用于Oracle的代码:

OracleCommand command = conn.CreateCommand(); // conn is my connection

string sql = "INSERT INTO table_name (ID, NAME, GENDER) VALUES (1, 'JOHN', 'M') RETURNING ID INTO :returnedId";

command.CommandText = sql;
command.Parameters.Add(new OracleParameter("returnedId", OracleDbType.Decimal));
command.ExecuteNoQuery();

我需要将它移植到SQL Server.这就是我正在做的事情:

SqlCommand command = conn.CreateCommand(); // conn is my connection

string sql = "INSERT INTO table_name (Id, Name, Gender) OUTPUT Inserted.Id As returnedId VALUES (1, "JOHN", "M")";

command.CommandText = sql;
command.Parameters.Add(new SqlParameter("returnedId", SqlDbType.Decimal));
command.ExecuteNoQuery();

该代码给我以下错误:

参数化查询需要未提供的参数:@returnedId

将Oracle RETURNING和:returnedId子句从Oracle 迁移到SQL Server 的正确方法是什么？

我试过OUTPUT Inserted.Id As @returnedId,以及改变SqlParameter到"@returnedId"没有成功.

OUTPUT是 SQL Server相当于 RETURNING INTO.

INSERT INTO table_name (ID, NAME, GENDER) 
OUTPUT INSERTED.ID 
VALUES (1, 'JOHN', 'M') ;

而C#:

Int32 outputID = (Int32)command.ExecuteScalar();
