Assembly 如何在Windows上将sqlite3与masm32一起使用

因为我必须在汇编程序中编写一个访问Sqlite3数据库的小库，所以我开始搜索如何使用Sqlite3.dll。我在fasm中找到了一种方法（我不得不使用masm32，因为许多原因都无助于解决问题，这只是一种必要），方法是通过

cinvoke

并引用看起来不可用的库。

我最想知道的是，我是否可以在masm中做类似的事情，或者我是否必须通过

GetProcAddress

获得我需要单独调用的每个函数的地址，为什么不呢？它很简单，如下所示：

.486
.model flat, stdcall
option casemap:none

include \masm32\include\masm32.inc
include \masm32\include\kernel32.inc
include \masm32\include\user32.inc
include sqlite3.inc

.data
szSQLDB         db  "MyDB.db3", 0
szRandQuery     db  "SELECT * FROM Quit ORDER BY RANDOM() LIMIT 1;", 0

.data?
hDBase          dd  ?

.code
START:
    invoke  sqlite3_open, offset szSQLDB, offset hDBase

    call    GetQuitMsg

    invoke  sqlite3_close, hDBase

    invoke  ExitProcess, 0

GetQuitMsg proc
local   ppStmt

    invoke  sqlite3_prepare_v2, hDBase, offset szRandQuery, -1, addr ppStmt, 0
    invoke  sqlite3_step, ppStmt
    invoke  sqlite3_data_count, ppStmt
    .if eax !=0
        invoke  sqlite3_column_text, ppStmt, 0
        invoke  MessageBoxA, 0, eax, 0,0        
    .endif        
    ret
GetQuitMsg endp
end START

我使用makefile，Geany作为我的编辑器。zip包括测试数据库sqlite3.inc，但不包括sqlite3.dll。只要解压缩文件，将sqlite3.dll放到项目目录中，就可以了。我也不使用MS链接，而是使用GoLink，因为它不需要import libs，但是如果必须使用MS链接，我在附近的某个地方有一个SQLite导入库

这是我的示例代码：）

它将创建名为“file.db”的数据库文件，创建名为“DBI”的表，并插入多达三行的数据。插入数据三次后，它将使用MessageBoxA显示数据。nID作为标题，szName作为文本

享受我的代码的乐趣：）

请将INCLUDE、LIB和BIN环境添加到MASM安装路径

例如：

INCLUDE=C:\MASM32\INCLUDE

LIB=C:\MASM32\LIB

BIN=C:\MASM32\BIN

在命令提示下键入set时，请确保上面有路径
