Column names not sent to callback by _SQLite_Exec

[ILLBeBack]

The remarks in the help file for _SQLite_Exec states “The first row in the Callback sequence will be the column names”, and the example script indicates that in the “output”, but the column names are not output.

Am I missing something or is the documentation incorrect? Just try the example script in the help file for _SQLite_Exec.

AutoIt v3.3.6.1

I doubt it makes any difference, but I’ve tested with SQLite versions 3.7.6.2 & 3.7.6.3.

Looks like a documentation error to me. To get the column names via Exec you could do this query:

#include <sqlite.au3>
#include <sqlite.dll.au3>
#include <Array.au3>

Local $hQuery, $aRow
_SQLite_Startup()
ConsoleWrite("_SQLite_LibVersion=" & _SQLite_LibVersion() & @CRLF)
_SQLite_Open()
; Without $sCallback it's a resultless statement
_SQLite_Exec(-1, "Create table tblTest (a,b int,c single not null);" & _
        "Insert into tblTest values ('1',2,3);" & _
        "Insert into tblTest values (Null,5,6);")

Local $d = _SQLite_Exec(-1, "PRAGMA table_info(tblTest)", "_cb") ; Show table schema for each column

Func _cb($aRow)
    _ArrayDisplay($aRow, "Column Name = " & $aRow[1]) ; [1] = name
EndFunc   ;==>_cb

_SQLite_Close()
_SQLite_Shutdown()

But it would be easier to use _SQLite_GetTable2d() instead, that does return the column names in the first row.

@PsaltyDS, thanks’s for taking the time to post a script as it may help someone else, and I did test it and can verify it works.

The reason I posted this issue was to verify that the documentation is in error before reporting it as a “bug” as I’ve had a very nasty reply from Dev once before when I overlooked something, even though I put in a great deal of time and research beforehand, not to mention developing a script to duplicate the issue. I’ll give it a few more days to see if Dev replies before making a bug report.

This is a doc error. If you want the headers, just pass

".header on" & @CRLF & $sSQL

for the SQL parameter.

I never looked at this function as it is essentially useless.

Slick workaround, jchd. Thanks.
