c++ - 无法执行 sqlite SQL 文件来创建数据库

Question

我有一个带有长事务的 sql(文本文件)来创建数据库。

为此我正在使用 Kompex sqlite c++ 库:

// open database
Kompex::SQLiteDatabase *pDatabase = new Kompex::SQLiteDatabase(CT2A(strDBFilename), SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, 0);

// create statement instance for sql queries/statements
Kompex::SQLiteStatement *pStmt = new Kompex::SQLiteStatement(pDatabase);

strSQLCreateDB=get_file_contents(strSQLFilename).c_str(); // load the SQL file

try {
    pStmt->Sql(strSQLCreateDB);
    pStmt->ExecuteAndFree();        
} catch(Kompex::SQLiteException &exception)
{
    std::cerr << "Exception Occured" << std::endl;
    exception.Show();
}

pDatabase->Close();

数据库是用 0 字节创建的，没有错误。即使没有 kompex 库，我也对任何示例代码感兴趣，以执行创建数据库的 sql 事务。

从 sqlite 浏览器执行数据库创建数据库没有错误。

这是SQL命令文件的一部分

/* Disable Foreign Keys */
pragma foreign_keys = off;
/* Begin Transaction */
begin transaction;

/* Database [scanlog(1)] */
pragma auto_vacuum=0;
pragma encoding='UTF-8';
pragma page_size=1024;

/* Drop table [ApplicationNames] */
drop table if exists [ApplicationNames];

/* Table structure [ApplicationNames] */
CREATE TABLE [ApplicationNames] (
  [Id] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, 
  [ApplicationName] TEXT, 
  [Icon] TEXT);
CREATE INDEX [IndexApps] ON [ApplicationNames] ([Id], [ApplicationName]);

/* Data [ApplicationNames] */
insert into [ApplicationNames] values(1, 'Windows System', null);
insert into [ApplicationNames] values(2, 'Internet Explorer', null); 
insert into [ApplicationNames] values(3, 'Google Chrome', null);

/* Commit Transaction */
commit transaction;

/* Enable Foreign Keys */
pragma foreign_keys = on;

这似乎可行:

// open connection to a DB
    if (SQLITE_OK != (ret = sqlite3_open_v2(CT2A(strDBFilename), &pDb, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, NULL)))
    {
        TRACE("Failed to open SQLite conn: %d\n", ret);
        break;
    } 

    // prepare the statement
    if (SQLITE_OK != (ret = sqlite3_prepare_v2(pDb, CT2A(strSQLCreateDB), -1, &query, NULL)))
    {
        TRACE("Failed to prepare SQLite script: %d, %s\n", ret, sqlite3_errmsg(pDb));
        break;
    }

    if (SQLITE_OK != (ret=sqlite3_exec(pDb, CT2A(strSQLCreateDB), NULL, 0, NULL)))
    {
        TRACE("Failed to execute SQLite script: %d, %s\n", ret, sqlite3_errmsg(pDb));
        break;
    }
