實(shí)際運(yùn)用中當(dāng)我用SqliteAdmin以及SQLite Expert Professional 2軟件新建Sqlite數(shù)據(jù)庫的時(shí)候在ASP.NET中是無法運(yùn)用的,老是報(bào)錯(cuò):文件不是一個(gè)合法的數(shù)據(jù)庫。后來采用一種方法,就是直接在ASP.NET里面利用引用入的DLL新建數(shù)據(jù)庫就可以用了。
string datasource = "d://test.db"; //數(shù)據(jù)庫文件的地址
System.Data.SQLite.SQLiteConnection.CreateFile(datasource); //產(chǎn)生文件
這樣產(chǎn)生出的test.db就可以在asp.net中運(yùn)用了,此時(shí)你即使用SqliteAdmin以及SQLite Expert Professional 2軟件打開它在里面建表都不影響它的使用了。
對(duì)Sqlite的操作其實(shí)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(shù)據(jù)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(shè)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(chǔ),默認(rèn)是Binary)
Data Source=filename;Version=3;BinaryGUID=False;
如果把Guid作為文本存儲(chǔ)需要更多的存儲(chǔ)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(jié)
Specify page size(指定頁大小)
Data Source=filename;Version=3;Page Size=1024;
Page Size 單位是字節(jié)
Disable enlistment in distributed transactions
Data Source=filename;Version=3;Enlist=N;
Disable create database behaviour(禁用創(chuàng)建數(shù)據(jù)庫行為)
Data Source=filename;Version=3;FailIfMissing=True;
默認(rèn)情況下,如果數(shù)據(jù)庫文件不存在,會(huì)自動(dòng)創(chuàng)建一個(gè)新的,使用這個(gè)參數(shù),將不會(huì)創(chuàng)建,而是拋出異常信息
Limit the size of database(限制數(shù)據(jù)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.
