无法从 csv 文件导入多于一行到 sqlite 数据库

Question

我在尝试将整个 csv 文件导入 sqlite 数据库时遇到问题。这些是我的终端命令：

sqlite3 DB.sql
create table table1 (id integer primary key, question VARCHAR(500), Aanswer VARCHAR(255), Banswer VARCHAR(255), Canswer VARCHAR(255), Danswer VARCHAR(255));
.mode csv
.import db.csv table1
select * from table1

和输出：

7,"Who's head did Courtney Cox say was on her body in Scream 2?","Heather Graham",Oprah,"*Jennifer Aniston","Demi Moore"

您会注意到它只在几个字段周围加上引号，这似乎是随机的...我不知道这是否是它不会继续导入下一行的原因。

谢谢！

编辑：

这是我的 csv 文件的前几行：

1,What movie follows Cher and Dionne named after great singers of the past that now do infomercials?,10 Things I Hate About You,Cant Hardly Wait,*Clueless,Freeway
2,What 90s movie did critic Janet Maslin describe as : A gale-force movie with the energy to blow audiences right out of the theater?,Avalanche,Aftershocks,Armageddon,*Twister
3,What actress declined Neve Campbell's role in Scream?,*Drew Barrymore,Carla Hatley,Courteney Cox,Rose McGowan

如果我把引号放在自己里面，它会吐出这样的东西：

"""What was the name of Milla Jovovich's character in the Fifth Element?""","""Billy""","""Fog""","""Mugger""","""*Leeloo"""

Answer 1

sqlite 的 .import 命令只能理解 LF (0xA) 行尾代码，而不是 CR (0xD)。在十六进制编辑器中检查您的输入文件。

Answer 2

您需要在带有空格的字段周围加上引号。

这样

C:\Documents and Settings\james\My Documents>type test.csv
1,field_with_no_spaces,'field with spaces'
2,field_with_no_spaces,'field with spaces'
3,field_with_no_spaces,'field with spaces'
4,field_with_no_spaces,'field with spaces'

C:\Documents and Settings\james\My Documents>sqlite3 test.dat
SQLite version 3.6.19
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> create table t1 (id integer primary key, q1, q2 );
sqlite> .mode csv
sqlite> .import test.csv t1
sqlite> select * from t1;
1,field_with_no_spaces,"'field with spaces'"
2,field_with_no_spaces,"'field with spaces'"
3,field_with_no_spaces,"'field with spaces'"
4,field_with_no_spaces,"'field with spaces'"

您将在带有空格的字段周围获得“额外”引号。不是问题。重要的是整个文件都被导入了，对吧？

如果你关心额外的问题，请关闭 csv 模式，像这样

sqlite> .mode list
sqlite> .separator ,
sqlite> select * from t1;
1,field_with_no_spaces,'field with spaces'
2,field_with_no_spaces,'field with spaces'
3,field_with_no_spaces,'field with spaces'
4,field_with_no_spaces,'field with spaces'

在你的数据周围加上引号，给出

1,What movie follows Cher and Dionne named after great singers of the past that now do infomercials?,10 Things I Hate About You,Cant Hardly Wait,*Clueless,Freeway
2,What 90s movie did critic Janet Maslin describe as : A gale-force movie with the energy to blow audiences right out of the theater?,Avalanche,Aftershocks,Armageddon,*Twister
3,What actress declined Neve Campbell's role in Scream?,*Drew Barrymore,Carla Hatley,Courteney Cox,Rose McGowan
