node.js - 如何使用Sequelize中的输出参数在SQL Server中执行存储过程？

Question

当我尝试在 Sequelize 中使用输出参数执行存储过程时出现错误:

Executing (default): spsPerson @PersonID=0 OUTPUT, @Firstname=N'test', @Lastname=N'test'

UnhandledPromiseRejectionWarning: SequelizeDatabaseError: Cannot use the OUTPUT option when passing a constant to a stored procedure.

这是代码:

  seq.query(
    'spsPerson @PersonID=:PersonID OUTPUT, @Firstname=:firstname, @Lastname=:lastname,
    {
      type: seq.QueryTypes.SELECT,
      replacements: {
        PersonID: 0,
        Firstname: 'test',
        Lastname: 'test'
      },
    }
  );

这是我的存储过程:

SET ANSI_NULLS OFF
GO

SET QUOTED_IDENTIFIER OFF
GO

CREATE PROCEDURE [dbo].[spsPerson]
    @PersonID INT OUTPUT,
    @Firstname VARCHAR(50),
    @Lastname VARCHAR(255)
AS
    INSERT INTO PersonTable (Firstname,  Lastname)
    VALUES (@Firstname,  @Lastname)

    SET  @PersonID  = SCOPE_IDENTITY()
GO

我不在乎输出参数，只想在不更改它的情况下执行此存储过程。

问题在于 OUTPUT 参数，您为其分配了 0 值，这导致了问题。

这是在 TSQL 中执行它以获取变量 @results 的结果的方式:

declare @results int;
exec dbo.spsPerson @results OUTPUT, @Firstname=N'test', @Lastname=N'test'
select @results;

如果你根本不关心结果:

exec dbo.spsPerson NULL, @Firstname=N'test', @Lastname=N'test'
