通过CSV格式在ClickHouse数据库中插入字符串数组

Question

我有一个简单的表：

CREATE TABLE t1
(
    v1 Int32, 
    a1 Array(Int32), 
    s2 Array(String)
) ENGINE = Memory

但无法弄清楚如何插入String数组：

insert into t1 format CSV 1,"[1,2]","[a1,a2]"

失败并显示以下错误：

Exception on client:
Code: 26. DB::Exception: Cannot parse quoted string: expected opening     quote: 
Could not print diagnostic info because two last rows aren't in    buffer (rare case)
: (at row 1)

Answer 1

抱歉，重新阅读了文档，发现数组中的字符串应该用单引号引起来。

 insert into t1 format CSV 1,"[1,2]","['a1','a2']"
