Asp.net中使用Sqlite數據庫的方法

編輯:ASP.NET基礎
實際運用中當我用SqliteAdmin以及SQLite Expert Professional 2軟件新建Sqlite數據庫的時候在ASP.NET中是無法運用的,老是報錯:文件不是一個合法的數據庫。後來采用一種方法,就是直接在ASP.NET裡面利用引用入的DLL新建數據庫就可以用了。

string datasource = "d:\\test.db"; //數據庫文件的地址

System.Data.SQLite.SQLiteConnection.CreateFile(datasource); //產生文件

這樣產生出的test.db就可以在asp.net中運用了,此時你即使用SqliteAdmin以及SQLite Expert Professional 2軟件打開它在裡面建表都不影響它的使用了。

對Sqlite的操作其實跟Access非常像的,只不過OleDB開頭的都變成了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;
This is just one connection string sample for the wrapping OdbcConnection class that calls the underlying ODBC Driver. See respective ODBC driver for more connection strings to use with this class.

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編碼)       Data Source=filename;Version=3;UseUTF16Encoding=True; With password(帶密碼的)       Data Source=filename;Version=3;Password=myPassword; Using the pre 3.3x database format(使用3.3x前數據庫格式)       Data Source=filename;Version=3;Legacy Format=True; Read only connection(只讀連接)       Data Source=filename;Version=3;Read Only=True; With connection pooling(設置連接池)       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作為文本存儲,默認是Binary)      Data Source=filename;Version=3;BinaryGUID=False;
      如果把Guid作為文本存儲需要更多的存儲空間 Specify cache size(指定Cache大小)
      Data Source=filename;Version=3;Cache Size=2000;
      Cache Size 單位是字節 Specify page size(指定頁大小)       Data Source=filename;Version=3;Page Size=1024;
      Page Size 單位是字節 Disable enlistment in distributed transactions       Data Source=filename;Version=3;Enlist=N; Disable create database behaviour(禁用創建數據庫行為)
      Data Source=filename;Version=3;FailIfMissing=True;
      默認情況下,如果數據庫文件不存在,會自動創建一個新的,使用這個參數,將不會創建,而是拋出異常信息 Limit the size of database(限制數據庫大小       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 (禁用日志回滾)       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/O's.
