Ruby on Rails的：多插入的SQLite3 ::的SQLException：近“”：语法错误：

Question

我需要做多次插入在database.It显示我的错误所有的时间

单一插入完美的作品：

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) 
=> [] 

多个插入并不在所有的工作：

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) 

问题是什么？如何在SQL中插入多个记录（创建记录） 在此先感谢

Answer 1

它看起来像SQLite不支持插入多个记录。
