Update in ADODB


Recommended Posts

I am using a proprietary database ( c-tree ) with an odbc driver written by Faircom.

I can use a free program ( Passport/ODBCTableview) to view table and even edit fields ( or add new records if needed. ) I use the the System ODBC entry created from the Faircom drivers.

Using those same drivers in Autoit, I can read any table/fields I want, but the .update command fails. I have tried with parenthesese and without. Strangely, the .updatecancel does not return an error.

Oh, and the supports() method returns true for the AdUpdate constant. Any ideas?

Any ideas?

Add COM Error handler to see the detailed error description.

Example how to do it is in Autoit's helpfile.

EDIT: Also

instead of

$rs = ObjCreate( "ADODB.RecordSet" )

$rs.activeconnection = $conn

$rs.cursortype = $adOpenStatic

$rs.locktype = $adLockOptimistic

$number = "   C45476"

$rs.Open( "SELECT * from nmmain where ""nmmain"".""number"" = '" & $number & "' ")

try

$rs = ObjCreate( "ADODB.RecordSet" )

$rs.cursortype = $adOpenStatic

$rs.locktype = $adLockOptimistic

$number = "   C45476"

$rs.Open( "SELECT * from nmmain where ""nmmain"".""number"" = '" & $number & "' ", $conn)

In addition to what Zedna suggested (in particular the COM error handler), you could try update (or delete) from a separate UPDATE query.

Of course, only try this on a work copy, not on the production version!

Something along the line:

...
$rs = ObjCreate( "ADODB.RecordSet" )
$rs.activeconnection = $conn
$rs.cursortype = $adOpenStatic
$rs.locktype = $adLockOptimistic

$number = " C45476"
$rs.Open( "update nmmain set nmmain.number = ' Z99999' where nmmain.number = '" & $number & "';")
$rs.close

gives ?
