利用线程存储检测数据，点击按钮  发送  邮件  保存数据。   第一次保存数据没问题，数据也能保存进sqlite.
第二次就会出现  UNALIGNED，怎么解决？为什么第一次没出现？

以下是代码，是非常通用的open ，insert，close。
```c
static int testdb1(void)
{
ALIGN(256) 
    sqlite3* db = NULL;
ALIGN(256)    char* sql;
    char* pErrMsg = 0;
    char** azResult;
    int rc;
    int nrow = 0;
    int ncolumn = 0;

rt_kprintf("<br>=====case 1:<br>");

rc = sqlite3_open(DB_FILE, &db);
    if(rc)
    {
        rt_kprintf("Can’t open database: %s<br>", sqlite3_errmsg(db));
        sqlite3_close(db);
        return -1;
    }

rt_kprintf("opened a sqlite3 database named %s successfully!<br>", DB_FILE);

sql = "CREATE TABLE test(ID INTEGER PRIMARY KEY,AGE INTEGER,LEVEL INTEGER,"
            "NAME VARCHAR(12),SALARY REAL);";
    sqlite3_exec(db, sql, 0, 0, &pErrMsg);
    JUDGE_ERR(pErrMsg);

sql = "INSERT INTO test VALUES(NULL, 1, 1, '201312', 120.9);";
    sqlite3_exec(db, sql, 0, 0, &pErrMsg);
    JUDGE_ERR(pErrMsg);

sql = "SELECT * FROM test";
    sqlite3_get_table(db, sql, &azResult, &nrow, &ncolumn, &pErrMsg);
    JUDGE_ERR(pErrMsg);
    _select_show(nrow, ncolumn, azResult);

//    sql = "DELETE FROM test WHERE AGE = 1;";
//    sqlite3_exec(db, sql, 0, 0, &pErrMsg);
//    JUDGE_ERR(pErrMsg);

sqlite3_free_table(azResult);
    sqlite3_close(db);

return 0;
}
```
提示对齐，让去哪里对齐呢？
