iphone sqlite 问题 : "out of memory" on sqlite3_prepare_v2

Question

我想知道是否有人可以帮助我理解这段代码有什么问题。我从来没有通过 sqlite3_prepare_v2 语句，调试器说:

'NSInternalInconsistencyException'，原因:'创建添加语句时出错。 '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

我从未打开过数据库...我认为这就是问题所在。
