Asp.net中使用Sqlite数据库的方法 |
实际运用中当我用SqliteAdmin以及SQLite Expert Professional 2软件新建Sqlite数据库的时候在ASP.NET中是无法运用的,老是报错:文件不是一个合法的数据库 。后来采用一种方法,就是直接在ASP.NET里面利用引用入的DLL新建数据库就可以用了 。 string datasource = "d:\\test.db"; //数据库文件的地址 System.Data.SQLite.SQLiteConnection.CreateFile(datasource); //产生文件 这样产生出的test.db就可以在asp.net中运用了,此时你即使用SqliteAdmin以及SQLite Expert Professional 2软件打开它在里面建表都不影响它的使用了 。 对Sqlite的操作其实跟Access非常像的,只不过OleDB开头的都变成了SQLite而已… .NET Framework Data Provider for ODBC DRIVER=SQLite3 ODBC Driver; Database=mydb.db; LongNames=0; Timeout=1000; NoTXN=0;SyncPragma=NORMAL; StepAPI=0; SQLite3 ODBC Driver DRIVER=SQLite3 ODBC Driver; Database=mydb.db; LongNames=0; Timeout=1000; NoTXN=0;SyncPragma=NORMAL; StepAPI=0; SQLite.NET Basic(基本的)
Data Source=filename;Version=3;
Using UTF16(使用UTF16编码)
Data Source=filename;Version=3;UseUTF16Encoding=True;
With password(带密码的)
Data Source=filename;Version=3;Password=myPassword;
Using the pre 3.3x database format(使用3.3x前数据库格式)
Data Source=filename;Version=3;Legacy Format=True;
Read only connection(只读连接)
Data Source=filename;Version=3;Read Only=True;
With connection pooling(设置连接池)
Data Source=filename;Version=3;Pooling=False;Max Pool Size=100;
Using DateTime.Ticks as datetime format()
Data Source=filename;Version=3;DateTimeFormat=Ticks;
The default value is ISO8601 which activates the use of the ISO8601 datetime format Store GUID as text(把Guid作为文本存储,默认是Binary)
Data Source=filename;Version=3;BinaryGUID=False;
如果把Guid作为文本存储需要更多的存储空间 Specify cache size(指定Cache大小)
Data Source=filename;Version=3;Cache Size=2000; Cache Size 单位是字节 Specify page size(指定页大小)
Data Source=filename;Version=3;Page Size=1024;
Page Size 单位是字节 Disable enlistment in distributed transactions
Data Source=filename;Version=3;Enlist=N;
Disable create database behaviour(禁用创建数据库行为)
Data Source=filename;Version=3;FailIfMissing=True; 默认情况下,如果数据库文件不存在,会自动创建一个新的,使用这个参数,将不会创建,而是抛出异常信息 Limit the size of database(限制数据库大小)
Data Source=filename;Version=3;Max Page Count=5000;
The Max Page Count is measured in pages. This parameter limits the maximum number of pages of the database.
Disable the Journal File (禁用日志回滚) Data Source=filename;Version=3;Journal Mode=Off;
This one disables the rollback journal entirely. Persist the Journal File(持久)
Data Source=filename;Version=3;Journal Mode=Persist;
This one blanks and leaves the journal file on disk after a commit. Default behaviour is to delete the Journal File after each commit. Controling file flushing
Data Source=filename;Version=3;Synchronous=Full;
Full specifies a full flush to take action after each write. Normal is the default value. Off means that the underlying OS flushes I/Os.
