iphone sqlite问题:sqlite3_prepare_v2上的"内存不足"

Question

我想知道是否有人可以帮我理解这段代码有什么问题.我从未通过sqlite3_prepare_v2语句,调试器说:

'NSInternalInconsistencyException',原因:'创建add语句时出错.'内存不足''

    static sqlite3 *database = nil;
sqlite3_stmt *addStmt = nil;

if(addStmt == nil) {
    NSLog(@"About to add start time...\n");
    const char *sql = "INSERT INTO games_played(start) VALUES(?)";     
    if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK)
        NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database));
    NSLog(@"add statement created successfully!\n");
}
NSLog(@"About to bind start time...\n");
sqlite3_bind_text(addStmt, 1, @"start time", -1, SQLITE_TRANSIENT);

Answer 1

我从未打开数据库...我认为这就是问题所在.

Answer 2

它不是一个bug,问题是你永远不会打开数据库.例如:

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