sqlite3可用命令列實現簡便操作,方便手工資料庫錄入進行測試, 方法如下:
#sqlite3

常用的一些命令解析:
建立表： create table table_name(filed1Name filed1Property,filed2Name filed2Property);
顯示資料庫中的表：.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
匯入資料：將txt檔案中的資料到匯入到表中, data.txt中每一列用”|”分隔, |兩邊不要空格,檔案末尾不要有空行，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’);
查詢記錄：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;
