Catching ADODB SQL errors.

6 posts in this topic

I've looked around but i'm having trouble finding what i need. I need to catch the SQL error output for a statement.

Example:

Global $adoCn = ObjCreate( "ADODB.Connection" )
$adoCn.Properties("Prompt") = 2; 1=PromptAlways, 2=PromptComplete

$ConnectionString = "DRIVER={Oracle in instantclient_11_2};data source=src"

        $adoCn.ConnectionString = $ConnectionString
        $adoCn.Open
        If @error Then
         MsgBox(0, "Problem", "SQL Connection Failed")
        Else


$adoCn.Execute("Blah blah SQL here")
... ?? catch error ?

So i can run a SQL statement. and something like "Select * from dba_users"  is easy to catch. if my record set is zero then i can do some error code.

Problem is i'm trying to write a little tool that can manage passwords. so i want to do an "alter user identified by "xxxx""  Statement. there's no return and if the alter fails i want to get back the error why (maybe password was too weak or other reasons)

But @error doesn't seem to contain anything from the sql.  in fact i'm not even sure how to continue the script . seems the whole thing just dies with a "The requested action with this object has failed.:" error.

ObjEvent

Look in example for Func _ErrFunc....

 

is there a better example of this? doesn't appear to do anything.

if i do this 

ObjEvent ( $adoCn, "_ErrFunc" )

then define the _errFunc as in the example the script still crashes. all I get is "The requested action with this object has failed.:"   _errFunc is never called.

mLipok is talking about:

Local $oErrorHandler = ObjEvent("AutoIt.Error", "_ErrFunc")

; Your code goes here

; User's COM error function. Will be called if COM error occurs
Func _ErrFunc($oError)
    ; Do anything here.
    ConsoleWrite(@ScriptName & " (" & $oError.scriptline & ") : ==> COM Error intercepted !" & @CRLF & _
            @TAB & "err.number is: " & @TAB & @TAB & "0x" & Hex($oError.number) & @CRLF & _
            @TAB & "err.windescription:" & @TAB & $oError.windescription & @CRLF & _
            @TAB & "err.description is: " & @TAB & $oError.description & @CRLF & _

exactly.

here is extended example:

Local $oErrorHandler = ObjEvent("AutoIt.Error", "_ErrFunc")
Global $adoCn = ObjCreate("ADODB.Connection")

$adoCn.Properties("Prompt") = 2; 1=PromptAlways, 2=PromptComplete

$ConnectionString = "DRIVER={Oracle in instantclient_11_2};data source=src"

$adoCn.ConnectionString = $ConnectionString
$adoCn.Open
If @error Then
    MsgBox(0, "Problem", "SQL Connection Failed")
Else


    $adoCn.Execute("Blah blah SQL here")
EndIf

; User's COM error function. Will be called if COM error occurs
Func _ErrFunc($oError)
    ; Do anything here.
    ConsoleWrite(@ScriptName & " (" & $oError.scriptline & ") : ==> COM Error intercepted !" & @CRLF & _
            @TAB & "err.number is: " & @TAB & @TAB & "0x" & Hex($oError.number) & @CRLF & _
            @TAB & "err.windescription:" & @TAB & $oError.windescription & @CRLF & _
            @TAB & "err.description is: " & @TAB & $oError.description & @CRLF & _
            @TAB & "err.source is: " & @TAB & @TAB & $oError.source & @CRLF & _
            @TAB & "err.helpfile is: " & @TAB & $oError.helpfile & @CRLF & _
            @TAB & "err.helpcontext is: " & @TAB & $oError.helpcontext & @CRLF & _
            @TAB & "err.lastdllerror is: " & @TAB & $oError.lastdllerror & @CRLF & _
            @TAB & "err.scriptline is: " & @TAB & $oError.scriptline & @CRLF & _
            @TAB & "err.retcode is: " & @TAB & "0x" & Hex($oError.retcode) & @CRLF & @CRLF)
EndFunc   ;==>_ErrFunc

and console output:

OK got it, I thought I was supposed to catch errors from the ADODB object directly. changing it to "AutoIt.Error" catches the COM error. thanks for the help
