Answer 1

使用此

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

例如

INSERT INTO example
  (example_id, name, value, other_value)
VALUES
  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

Answer 2

仅在会议表中的所选用户的商店ID（用户表的ID）以逗号（，）分隔的“与会者”字段。假设选择id为1,7和5的用户，然后将1,5,7存储到会议表
在提取时，您可以获取用户

$q="SELECT username from user_table where ID IN (1,5,7)";
