Ruby on rails： 多次插入 SQLite3：：SQLException： 接近 "," ： 语法错误：

Question

我需要在数据库中进行多次插入。它总是显示一个错误

单次插入工作完美:

CONN = ActiveRecord::Base.connection
irb(main):271:0> inserts.push'(1,2,3,4,5,6)'
=> ["(1,2,3,4,5,6)"]
sql="INSERT INTO signals_rmas (groupsnorm_id, arraydb_id, probeset_id,signal,updated_at,created_at) VALUES #{inserts.join(", ")}"
irb(main):276:0> CONN.execute sql
   (32.3ms)  INSERT INTO signals_rmas (groupsnorm_id, arraydb_id, probeset_id,signal,updated_at,created_at) VALUES (1,2,3,4,5,6)
=> []

多次插入根本不起作用:

irb(main):272:0> inserts.push'(7,8,9,10,11,12)'
=> ["(1,2,3,4,5,6)", "(7,8,9,10,11,12)"]
irb(main):278:0>sql="INSERT INTO signals_rmas (groupsnorm_id, arraydb_id, probeset_id,signal,updated_at,created_at) VALUES #{inserts.join(", ")}"
=> "INSERT INTO signals_rmas (groupsnorm_id, arraydb_id, probeset_id,signal,updated_at,created_at) VALUES (1,2,3,4,5,6), (7,8,9,10,11,12)"
irb(main):279:0> CONN.execute sql
   (0.4ms)  INSERT INTO signals_rmas (groupsnorm_id, arraydb_id, probeset_id,signal,updated_at,created_at) VALUES (1,2,3,4,5,6), (7,8,9,10,11,12)
ActiveRecord::StatementInvalid: SQLite3::SQLException: near ",": syntax error: INSERT INTO signals_rmas (groupsnorm_id, arraydb_id, probeset_id,signal,updated_at,created_at) VALUES (1,2,3,4,5,6), (7,8,9,10,11,12)

有什么问题吗?我如何在sql中插入多个记录作为时间?(创建记录)提前感谢

看起来SQLite不支持插入多个记录
