常用的一些命令解析:

創建表： create table table_name(filed1Name filed1Property,filed2Name filed2Property);

顯示數據庫中的表：.table

顯示錶結構：.schema table_name

刪除表: .drop table table_name

退出：.exit

顯示錶所有內容: .dump table_name

導入數據：將txt文件中的數據到導入到表中, data.txt中每一列用”|”分隔, |兩邊不要空格,文件末尾不要有空行，例如：1|rainkey|tencent

注意：在android 上面執行的時候將text_name.txt存放到databases所在目錄

.import text_name.txt table_name

插入記錄：insert into table_name values(‘key’,’value’);

查找記錄：select * from table_name;

從第三行開始查詢10條記錄：select * from table_name limit 3,10;

刪除記錄：delete from table_name where field1=value;

更新操作：update table_name set name=’rainkey’ where id=1;
