SQLite 下载与SQLite.lib生成

一、SQLite下载

SQLite可以在SQLite 官网http://www.sqlite.org/download.html下载 sqlite-dll-win32-x86-3070600.zip（这个时候发现压缩包里只有dll和def文件。）

二、SQLite.lib生成

1、将sqlite-dll-win32-x86-3070600.zip 下载到自己的本地电脑上以后，（假设存储地址：E:/test）；

2、打开LIB.EXE所在的目录，VC6.0下的LIB.EXE一般都存放在C:/Program Files/Microsoft Visual Studio/VC98/Bin下；

3、打开“运行”—>”cmd”进入DOS下，使用CD 更改到LIB.EXE所在的当前路径，如：cd C:/Program Files/Microsoft Visual Studio/VC98/Bin

4、在DOS下输入LIB /out:E:/test/sqlite3.lib /MACHINE:IX86 /DEF:E:/test/sqlite3.def

5、回车之后，打开E:/test文件就会发现多了两个文件sqlite3.lib和sqlite3.exp

注：

生成时可能会报错：

在C:\Program Files\Microsoft Visual Studio 8

搜索 MSPDB80

将其copy->C:\Program Files\Microsoft Visual Studio 8\VC\bin

生成.lib后，建立工程时要删除，要不然编译报错

我生成的

sqlite3.lib

sqlite3.exp

#include <Stdio.h>

//包含SQLite3头文件

#include "sqlite3.h"

#pragma comment(lib,"sqlite3.lib")

int main( int argc, char* argv[] )

{

int nRet;

sqlite3 *db=NULL;

nRet = sqlite3_open( "xx.db", &db );

if ( 0 != nRet )

{

printf("Open db error %s\n", sqlite3_errmsg(db));

sqlite3_close( db );

}else

{

printf( "open db success\n" );

}

//create a table

char *zErrMsg = 0;

char *sql = " CREATE TABLE SensorData( ID INTEGER PRIMARY KEY,SensorID INTEGER,SiteNum INTEGER,Time VARCHAR(12),SensorParameter REAL);";

printf( "%s\n", sql );

nRet = sqlite3_exec( db , sql , 0 , 0 , &zErrMsg );

if ( 0 != nRet )

{

printf("Create table falure, MSG:%s\n", zErrMsg);

}else

{

printf( "Create table success\n" );

}

//insert data

sql = "INSERT INTO \"SensorData\" VALUES(NULL , 1 , 1 , '200605011206', 18.9 );" ;

nRet = sqlite3_exec( db , sql , 0 , 0 , &zErrMsg );

if ( 0 != nRet )

{

printf("Insert Error:%s", zErrMsg);

}else

{

printf("Insert OK\n");

}

//insert data

sql = "INSERT INTO \"SensorData\" VALUES(NULL , 1 , 1 , '200605011306', 16.4 );" ;

nRet = sqlite3_exec( db , sql , 0 , 0 , &zErrMsg );

if ( 0 != nRet )

{

printf("Insert Error:%s", zErrMsg);

}else

{

printf("Insert OK\n");

}

//update data

sql = "UPDATE SensorData SET SensorParameter=1000.01,SensorID=123 WHERE SensorParameter=100.01";

nRet = sqlite3_exec( db , sql , 0 , 0 , &zErrMsg );

if ( 0 != nRet )

{

printf("Update Error:%s", zErrMsg);

}else

{

printf("Update OK\n");

}

//delete data

sql = "DELETE FROM SensorData WHERE SensorID=123";

nRet = sqlite3_exec( db , sql , 0 , 0 , &zErrMsg );

if ( 0 != nRet )

{

printf("Delete Error:%s", zErrMsg);

}else

{

printf("Delete OK\n");

}

//query data

int nrow = 0, ncolumn = 0;

char **azResult; //二维数组存放結果

sql = "SELECT * FROM SensorData ";

sqlite3_get_table( db , sql , &azResult , &nrow , &ncolumn , &zErrMsg );

int i = 0 ;

printf( "row:%d column=%d \n" , nrow , ncolumn );

printf( "\nThe result of querying is : \n" );

for( i=0 ; i<( nrow + 1 ) * ncolumn ; i++ )

printf( "azResult[%d] = %s\n", i , azResult[i] );

//释放azResult 的內存空間

sqlite3_free_table( azResult );

//关闭数据库

sqlite3_close( db );

return 0;

}

注：请将您的sqlite3.h、sqlite3.lib、sqlite3.dll放到你的工程目录下！

sqlite3.h ->C:\Program Files\Microsoft Visual Studio 8\VC\include

sqlite3.lib ->C:\Program Files\Microsoft Visual Studio 8\VC\lib

sqlite3.dll ->C:\Program Files\Microsoft Visual Studio 8\VC\bin

执行本程序后其输出结果如下：

open db success

CREATE TABLE SensorData( ID INTEGER PRIMARY KEY,SensorID INTEGER,SiteNum INTEGER,Time VARCHAR(12),SensorParameter REAL);

Create table success

Insert OK

Update OK

Delete OK

row:2 column=5

The result of querying is :

azResult[0] = ID

azResult[1] = SensorID

azResult[2] = SiteNum

azResult[3] = Time

azResult[4] = SensorParameter

azResult[5] = 1

azResult[6] = 1

azResult[7] = 1

azResult[8] = 200605011206

azResult[9] = 18.9

azResult[10] = 2

azResult[11] = 1

azResult[12] = 1

azResult[13] = 200605011306

azResult[14] = 16.4
