_SQLite_FetchData example: run-time error

Recommended Posts

When run, this example shows in the Console:

The most likely reason is that it cannot find the sqlite3.dll file.  I think the error comes from when the SQLite.dll.au3 udf used to download the sqlite dll file if it wasn't found.

Try this slightly modified example.  Make sure you have the correct path for the sqlite3.dll file.

#include <Constants.au3>
#include <SQLite.au3>
;~ #include <SQLite.dll.au3>

Local $hQuery, $aRow, $aNames

_SQLite_Startup("c:\program files\sqlite\sqlite3.dll", False, True) ;<== Change to your sqlite3 path
If @error Then Exit MsgBox($MB_ICONERROR, "SQLITE ERROR", "Unable to start up SQLite")

ConsoleWrite("_SQLite_LibVersion=" & _SQLite_LibVersion() & @CRLF)
_SQLite_Open() ; open :memory: Database
_SQLite_Exec(-1, "CREATE TABLE aTest (A,B,C);")
_SQLite_Exec(-1, "INSERT INTO aTest(a,b,c) VALUES ('c','2','World');")
_SQLite_Exec(-1, "INSERT INTO aTest(a,b,c) VALUES ('b','3',' ');")
_SQLite_Exec(-1, "INSERT INTO aTest(a,b,c) VALUES ('a','1','Hello');")
_SQLite_Query(-1, "SELECT ROWID,* FROM aTest ORDER BY a;", $hQuery)
_SQLite_FetchNames($hQuery, $aNames)
ConsoleWrite(StringFormat(" %-10s  %-10s  %-10s  %-10s ", $aNames[0], $aNames[1], $aNames[2], $aNames[3]) & @CRLF)
While _SQLite_FetchData($hQuery, $aRow, False, False) = $SQLITE_OK ; Read Out the next Row
    ConsoleWrite(StringFormat(" %-10s  %-10s  %-10s  %-10s ", $aRow[0], $aRow[1], $aRow[2], $aRow[3]) & @CRLF)
WEnd
_SQLite_QueryFinalize($hQuery)
_SQLite_Exec(-1, "DROP TABLE aTest;")
_SQLite_Close()
_SQLite_Shutdown()

; Output:
; rowid       A           B           C
; 3           a           1           Hello
; 2           b           3
; 1           c           2           World

BTW, prefer higher-level functions (GetTable[2d]) instead of looping "fetch" by yourself.

Thank you to both.

My point (which I failed to make) is that an Example Script doesn't work out-of-the-box.

Either it should work when someone clicks on "Open this script" and runs it, or what to do when it doesn't run should show in a message box.

I suggest that the Help needs to be fixed, in some way. 

BTW I have just copied this script to a folder where I have the .dll . It works AOK there.

It was decided by Jon long time ago that the _SQLite_OpenStartup function of the standard UDF wouldn't any more check the DLL version and download the latest, since it was eating a very high percentage of the AutoIt website load.

It's now the responsability of the app designer to provide the DLL.
