MySQL & Blob Help!

Recommended Posts

Can someone please help... I am having problems determining where the problem is in my code...

(MyODBC is required)

The problem I am having is the adding of the files to the db. It throws errors and adds the record without the binary data.

I have tested the ability to both read and write and everything seems to work but the binary part.

1) Created MySQL db called 'testdb'

2) Created db user name: joe pass: blo

3) Logged in as joe and executed this script against the testdb:

CREATE TABLE files(

file_id SMALLINT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY,

file_name VARCHAR(64) NOT NULL,

file_size MEDIUMINT UNSIGNED NOT NULL,

file MEDIUMBLOB NOT NULL);

4) Created script to add record to db:

CreateRecord.au3

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

$ado = ObjCreate( "ADODB.Connection" )

$adoRS = ObjCreate( "ADODB.RecordSet" )

$ado.Open( "DRIVER={MySQL ODBC 3.51 Driver};SERVER=SERVERIPGOESHERE;DATABASE=testdb;USER=joe;PASSWORD=blo;OPTION=1 + 2 + 8 + 32 + 2048 + 16384;" )

$adoRS.CursorType = 2

$adoRS.LockType = 3

$adoRS.Open( " Select * from files", $ado )

$oStream = ObjCreate( "ADODB.Stream")

$adoRS.AddNew

$oStream.Type=1

$oStream.Open

$var = FileOpenDialog("Locate Image", "C:\", "Images (*.jpg;*.bmp;*.tif)", 1)

$oStream.LoadFromFile = $var

$adoRS.Fields("file_name").Value = 'filenametest.tif'

$adoRS.Fields("file_size").Value = $oStream.size

$adoRS.Fields("file").Value = $oStream.read

$adoRS.Update

$adoRS.Close

$ado.Close

Func MyErrFunc()

$HexNumber=hex($oMyError.number,8)

Msgbox(0,"AutoItCOM Test","We intercepted a COM Error !" & @CRLF & @CRLF & _

"err.description is: " & @TAB & $oMyError.description & @CRLF & _

"err.windescription:" & @TAB & $oMyError.windescription & @CRLF & _

"err.number is: " & @TAB & $HexNumber & @CRLF & _

"err.lastdllerror is: " & @TAB & $oMyError.lastdllerror & @CRLF & _

"err.scriptline is: " & @TAB & $oMyError.scriptline & @CRLF & _

"err.source is: " & @TAB & $oMyError.source & @CRLF & _

"err.helpfile is: " & @TAB & $oMyError.helpfile & @CRLF & _

"err.helpcontext is: " & @TAB & $oMyError.helpcontext _

)

SetError(1) ; to check for after this function returns

Endfunc

5) Created script to read records from db:

ReadRecords.au3

$ado = ObjCreate( "ADODB.Connection" )

$adoRS = ObjCreate( "ADODB.RecordSet" )

$ado.Open( "DRIVER={MySQL ODBC 3.51 Driver};SERVER=SERVERIPGOESHERE;DATABASE=testdb;USER=joe;PASSWORD=blo;OPTION=1 + 2 + 8 + 32 + 2048 + 16384;" )

$adoRS.CursorType = 2

$adoRS.LockType = 3

$adoRS.Open( " Select * from files", $ado )

While not $adoRS.EOF

MsgBox(4096, "Database", $adors.Fields( "file_size" ).Value, 5)

$adoRS.MoveNext

WEnd

bump :">

Sorry I don't know the syntax for this SQL;

You could use the workaround in AoutIT, example in last link in my signature. [uses binary string udf too, so you can dislay that field as text in GUI without resorting t binary save]

SQLcreateTableInsertRecord.au3

best, Randall!

(I'll be interested to hear if you work out the syntax...)
