mysql - 为单个列插入多个值

Question

我想在一个字段中将多个值插入MySQL，其余字段只包含一个值。

我试过下面的查询

INSERT INTO assessment_training(
  PARENT_SLNO
  RNO
  TRAINING_CATEGORY
  TRAINING_NAME
) 
VALUES (
  9,
  1,
  'Technical',
  (1,7)
);

错误＃1241

`INSERT INTO assessment_training(PARENT_SLNO,RNO,TRAINING_CATEGORY,TRAINING_NAME) VALUES (9,1,'Technical',(1,7))    Error Code: 1241. Operand should contain 1 column(s)`

Answer 1

您可以使用CONCAT()

INSERT INTO assessment_training(
  PARENT_SLNO,
  RNO,
  TRAINING_CATEGORY,
  TRAINING_NAME
) 
VALUES (
  9,
  1,
  'Technical',
  CONCAT("1", ",", "7")
);
