我正在尝试从文本文件中预填充我的SQlite表 - 尽管它编译得很好,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");
这就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:
DefaultPath:/ 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,路径是正常的,但没有任何内容可写......
感谢您的回答,帮助,建议......: - )
BR,
的Stefan
再次感谢您的不断帮助......
我改变如下:
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");
我的日志看起来像:

所以外观看起来很好 - 将创建DB,可以打开DB(因为没有故障问题),我能够将(查看GUI)数据插入表“伙伴”,但我无法插入数据通过文件......
