sqlite命令行工具简单操作

来源: lixianlin 分享至:

在Win32下面操作,先看下sqlite.exe的帮助:

D:\>sqlite3.exe -help
Usage: sqlite3.exe [OPTIONS] FILENAME [SQL]
FILENAME is the name of an SQLite database. A new database is created
if the file does not previously exist.
OPTIONS include:
   -help                show this message
   -init filename       read/process named file
   -echo                print commands before execution
   -[no]header          turn headers on or off
   -bail                stop after hitting an error
   -interactive         force interactive I/O
   -batch               force batch I/O
   -column              set output mode to 'column'
   -csv                 set output mode to 'csv'
   -html                set output mode to HTML
   -line                set output mode to 'line'
   -list                set output mode to 'list'
   -separator 'x'       set output field separator (|)
   -stats               print memory stats before each finalize
   -nullvalue 'text'    set text string for NULL values
   -version             show SQLite version
   -vfs NAME            use NAME as the default VFS

1、创建DB文件(存在的话则打开)

D:\>sqlite3.exe test.db
SQLite version 3.7.9 2011-11-01 00:52:41
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite>

说明:使用“.help”可以查看帮助,SQL语句使用分号";"结束。

2、创建表

sqlite> CREATE TABLE user(id int, name varchar(20));

3、查看创建表的SQL语句

sqlite> .schema user
CREATE TABLE user(id int, name varchar(20));

4、插入

sqlite> INSERT INTO user ('id', 'name') values(1, 'LiLei');

sqlite> INSERT INTO user ('id', 'name') values(2, 'HanMeimei');

5、查询

sqlite> SELECT * from user;
1|LiLei
2|HanMeimei

6、删除

sqlite> DELETE FROM user WHERE id=2;

7、更新

sqlite> UPDATE user SET name='Xiaoming' WHERE id=1;

8、删除表

sqlite> DROP TABLE user;
