Recommended Posts

My data table is:

1.thumb.png.7c63763f2cdbf855ff75eb5c0765

But when i run this script to insert to my listview:

.....
_SQLite_Query($dbntdh, "SELECT * FROM data;", $qre)
While _SQLite_FetchData($qre, $qrow) = $SQLITE_OK
    GUICtrlCreateListViewItem(_ArrayToString($qrow, "|"),$gui_ntdh_listtu)
WEnd
.....

He does not show me the texts, he show me the code, i don't know how to convert it to text, please help me:

I see the ID in column "STT" is good, but all other column text is not good. Thanks for your advanced helping!

It all looks like that data was stored as binary.

What is the result of:

select distinct typeof(Từ) from data;

(please check that I spelled the column name correctly!). Are you getting BLOB somewhere?

Maybe it stored data as binary, because i use this code to store data:

$currentTime = _Date_Time_SystemTimeToDateTimeStr(_Date_Time_GetSystemTime(), 1)
_SQLite_Exec($dbntdh, "INSERT INTO data (word, mean,time) VALUES ("&_SQLite_Encode($translated[0])&", "&_SQLite_Encode($translated[1])&", "&_SQLite_Encode($currentTime)&");")

When i use your code:

_SQLite_Query($dbntdh, "SELECT distinct typeof(word) FROM data;", $qre)

--->>> He return BLOB

So what should i do know, should i change the store code, or anything else to get BLOB data to display as text.

Thanks for your suggestion, i think he store data as binary, so i use the autoit function BinaryToString to translate it to text as what i want to display:

_SQLite_Query($dbntdh, "SELECT * FROM data;", $qre)
While _SQLite_FetchData($qre, $qrow) = $SQLITE_OK
  GUICtrlCreateListViewItem(BinaryToString($qrow[0], 4)&"|"&BinaryToString($qrow[1], 4)&"|"&BinaryToString($qrow[2], 4)&"|"&BinaryToString($qrow[3], 4),$gui_ntdh_listtu)
WEnd

Thanks so much, love you so much ! !:thumbsup:

You should have used _SQLite_FastEscape() instead of _SQLite_Encode(). See help to understand the difference.

Rather than having leaving the data in a wrong format, I highly recommend changing its type definitely. Make a copy of the DB just in case and apply this:

update data set word = cast(word as text);
update data set mean = cast(mean as text);
update data set time = cast(time as text);

Double check that the vietnamese text is OK after that!

Note that you can also use SQLite faster internal functions to format the ouput to your needs, simplifying AutoIt code:

_SQLite_Query($dbntdh, "SELECT word || '|' || mean || '|' || time FROM data;", $qre)
While _SQLite_FetchData($qre, $qrow) = $SQLITE_OK
    GUICtrlCreateListViewItem($qrow[0], $gui_ntdh_listtu)
WEnd
