Question

我正试图在iphone上使用sqlite3在表格中插入一些数据... 我从各个步骤得到的所有错误代码表明操作应该是成功的，但事实上，表格仍然是空的...我想我错过了一些东西......

这里是代码：

sqlite3 *database = nil;
NSString *dbPath = [[[ NSBundle mainBundle ] resourcePath ] stringByAppendingPathComponent:@"placemarks.sql"];

if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK){

sqlite3_stmt *insert_statement = nil;
//where int pk, varchar name,varchar description, blob picture
static char *sql = "INSERT INTO placemarks (pk, name, description, picture) VALUES(99,'nnnooooo','dddooooo', '');";
    if (sqlite3_prepare_v2(database, sql, -1, &insert_statement, NULL) != SQLITE_OK) {
        NSAssert1(0, @"Error: failed to prepare statement with message '%s'.", sqlite3_errmsg(database));
    }

int success = sqlite3_step(insert_statement);

int finalized = sqlite3_finalize(insert_statement);

NSLog(@"success: %i finalized: %i",success, finalized);

NSAssert1(101, @"Error: failed to insert into the database with message '%s'.", sqlite3_errmsg(database));


sqlit3_step returns 101, so SQLITE_DONE, which should be ok..

如果我在命令行中执行sql语句，它可以正常工作......

谁有个主意呢？可能是因为写在placemarks.sql中有问题，因为它在资源文件夹中？

发现它是什么！我想...我无法修改资源文件夹中的* .sql，我必须先在应用程序的文档中复制并使用该副本！

sqlite3之后没有插入 - ＆gt;插入 - ＆gt; SQLITE_DONE
