Iphone SQlite - 从文本字段填充表格

Question

我正在尝试从文本文件中预填充我的 SQlite 表 - 虽然编译正常，但不会插入任何行：

NSLog(@"Insert Table for English");


    char *errorMsg;

    NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath ] stringByAppendingPathComponent:@"english.sql"];

    NSLog(@"DefaultPath: %@", defaultDBPath);

    NSString *sql = [[[NSString alloc] initWithContentsOfFile:defaultDBPath  
                                           encoding:NSUTF8StringEncoding 
                                              error:NULL] autorelease];

    if (sqlite3_exec(database,[sql UTF8String],NULL,NULL, &errorMsg) != SQLITE_OK) {
        NSAssert1(0, @"Error loading update file: %s", errorMsg);
    }

    NSLog(@"I should have written something");

这是我的文本文件的样子：

BEGIN TRANSACTION;
INSERT INTO PARTNER(branche) VALUES('Choose music for the Ceremony');
COMMIT;

我在这里创建数据库：

-(void)createDatabase {

NSUserDefaults *userSETTINGS = [NSUserDefaults standardUserDefaults];

NSLog(@"HUHU - schau ma mal: Database = %d", [userSETTINGS integerForKey:@"Database"]);


if ([userSETTINGS integerForKey:@"Database"] == 0) {


    if (sqlite3_open([[self dataFilePath] UTF8String], &database) != SQLITE_OK) {
        sqlite3_close(database);
        NSAssert(0, @"Failed to open database");
    }

    char *errorMsg;
    //sqlite3_stmt *statement;
    NSString *createSQL = @"CREATE TABLE IF NOT EXISTS PARTNER (id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, branche TEXT, company TEXT, name TEXT, phone TEXT, email TEXT, price INT, notes TEXT, done TEXT);";
    if (sqlite3_exec(database, [createSQL UTF8String], NULL, NULL, &errorMsg) != SQLITE_OK) {
        sqlite3_close(database);
        NSAssert1(0, @"Error createing table: %s", errorMsg);
    }

    NSUserDefaults *userSETTINGS = [NSUserDefaults standardUserDefaults];
    [userSETTINGS setInteger:1 forKey:@"Database"];

    NSLog(@"HUHU - schau ma mal: Database = %d", [userSETTINGS integerForKey:@"Database"]);

[self fillDatabase];

} else {

    NSLog(@"Database wurde schon angelegt");
    [self readDatabase];

}

}

日志文件告诉我，defaultDBPath 是：

默认路径：/Users/sl/Library/Application Support/iPhone Simulator/User/Applications/0BE2EDC6-F070-43BE-9666-310257B495B9/WeddingPlanner.app/english.sql

我错过了什么？数据库是正确的，路径是好的，但什么都不会写...

感谢您的回答、帮助、建议... :-)

BR，

再次感谢您的持续帮助...

我做了如下改动：

if (sqlite3_open_v2([[self dataFilePath] UTF8String], &database, SQLITE_OPEN_READWRITE, nil) != SQLITE_OK) {
        sqlite3_close(database);
        NSAssert(0, @"Failed to open database");
    }

    NSLog(@"Insert Table for English");


    char *errorMsg;

    NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath ] stringByAppendingPathComponent:@"e.sqlite"];

    NSLog(@"DefaultPath: %@", defaultDBPath);

    NSString *sql = [[[NSString alloc] initWithContentsOfFile:defaultDBPath  
                                           encoding:NSUTF8StringEncoding 
                                              error:NULL] autorelease];

    if (sqlite3_exec(database,[sql UTF8String],NULL,NULL, &errorMsg) != SQLITE_OK) {
        NSAssert1(0, @"Error loading update file: %s", errorMsg);
    }

    NSLog(@"Hier hätte ich schreiben sollen");

一切看起来都很好 - 将创建数据库，可以打开数据库（因为没有失败问题），我能够将（查看 GUI）数据插入到“合作伙伴”表中，但我无法插入通过文件获取数据...

The correct syntax for committing transaction 是

COMMIT TRANSACTION
