无法创建表;为什么此代码会失败?

我对SQLite v3.22.0和AutoIt v3.3.14.3有问题。尝试创建数据库可以工作,但无法创建表。我使用AutoIt示例代码:

#include <MsgBoxConstants.au3>
#include <SQLite.au3>
#include <SQLite.dll.au3>

Local $hQuery, $aRow, $sMsg
_SQLite_Startup()
ConsoleWrite("_SQLite_LibVersion=" & _SQLite_LibVersion() & @CRLF)
_SQLite_Open() ; open :memory: Database
_SQLite_Exec(-1, "CREATE TABLE aTest (a,b,c);") ; CREATE a Table
_SQLite_Exec(-1, "INSERT INTO aTest(a,b,c) VALUES ('c','2','World');") ; INSERT Data
_SQLite_Exec(-1, "INSERT INTO aTest(a,b,c) VALUES ('b','3',' ');") ; INSERT Data
_SQLite_Exec(-1, "INSERT INTO aTest(a,b,c) VALUES ('a','1','Hello');") ; INSERT Data
_SQLite_Query(-1, "SELECT c FROM aTest ORDER BY a;", $hQuery) ; the query
While _SQLite_FetchData($hQuery, $aRow) = $SQLITE_OK
    $sMsg &= $aRow[0]
WEnd
_SQLite_Exec(-1, "DROP TABLE aTest;") ; Remove the table
MsgBox($MB_SYSTEMMODAL, "SQLite", "Get Data using a Query : " & $sMsg)
_SQLite_Close()
_SQLite_Shutdown()

; Output:
; Hello World

如果我请求SQLite错误,我会得到“库使用不正确”。这个案子有什么问题?
