c# - Oracle 返回 :variable equivalent using SQL Server

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();

我需要将其移植到 SQL Server。这就是我正在做的:

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:

the parameterized query expects the parameter which was not supplied: @returnedId

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

我尝试了 OUTPUT Inserted.Id As @returnedId 以及将 SqlParameter 更改为 "@returnedId" 但没有成功。

Answer 1

OUTPUT SQL Server 等同于RETURNING INTO .

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

和C#:

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