mysql - 从 MySQL 到 MS SQL Server 的 SQL 查询错误

Question

当我将以下 SQL 查询从 MySQL 导入到 MS SQL Server 时，出现警告“表级约束未指定列列表，表‘标记’。” 有谁能帮我解决这个问题吗？

以下是整个查询的一部分。(它是由 MySQL Workbench 生成的

CREATE TABLE Mark (
  student_id INT NOT NULL,
  exam_id INT NOT NULL,
  subject_id INT NOT NULL,
  mark VARCHAR(2) NULL,
  INDEX Student_id_idx ON Mark(student_id),
  INDEX Subject_id_idx ON Mark(subject_id),
  INDEX Exam_id_idx ON Mark(exam_id),
  CONSTRAINT exam_id
    FOREIGN KEY (exam_id)
    REFERENCES Exam (exam_id)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT student_id
    FOREIGN KEY (student_id)
    REFERENCES Student (student_id)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT subject_id
    FOREIGN KEY (subject_id)
    REFERENCES Subject (subject_id)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)

Answer 1

试试这个:

CREATE TABLE [dbo].[Mark] (
  [student_id] [int] NOT NULL,
  [exam_id] [int] NOT NULL,
  [subject_id] [int] NOT NULL,
  [mark] [varchar](2) NULL,

  FOREIGN KEY ([Exam_id]) REFERENCES [Exam]([Exam_id]),
  FOREIGN KEY ([Student_Id]) REFERENCES [Student]([Student_Id])
  FOREIGN KEY ([subject_id]) REFERENCES [Subject]([subject_id])
) ON [PRIMARY]
