如何将this 数据导入sqlite：

nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ sqlite3
SQLite version 3.31.1 2020-01-27 19:55:54
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.
sqlite> 
sqlite> .mode csv
sqlite> 
sqlite> .import BCCDC_COVID19_Dashboard_Case_Details.csv details;
CREATE TABLE details;(...) failed: near ";": syntax error
sqlite> .quit
nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ head BCCDC_COVID19_Dashboard_Case_Details.csv 
"Reported_Date","HA","Sex","Age_Group","Classification_Reported"
"2020-01-26","Out of Canada","M","40-49","Lab-diagnosed"

nicholas@mordor:~/csv$

引号似乎有问题的地方。

我还有tried不同的模式和其他设置：

sqlite> 
sqlite> .mode ascii
sqlite> .separator ","
sqlite>

没有成功。引用泛型documentation。

也许：

将使用csvsql 工具。

【问题讨论】：

标签： database sqlite csv text import

【解决方案1】：

双引号不是问题。问题是;。点命令不以分号 ; 结尾。命令行将分号解释为表名的一部分。

【讨论】：

啊，谢谢。我更新了q，数据还是有问题。

【解决方案2】：

出于某种原因，他们在 CSV 中的所有内容都加上了引号，所以：

nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ rm covid.db 
nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ touch covid.db
nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ csvsql --db sqlite:///covid.db --table cases --insert BCCDC_COVID19_Dashboard_Case_Details.csv 
nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ csvsql --db sqlite:///covid.db --table labs --insert BCCDC_COVID19_Dashboard_Lab_Information.csv 
nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ sqlite3 covid.db 
SQLite version 3.31.1 2020-01-27 19:55:54

哪个有效。
