Hi,

I'm having an issue uploading a image Blobs to a MS SQL Server and can't figure out where I'm going wrong (Using Powerbuilder 2017 R3, both in Desktop App and Appeon Mobile).

The Upload Blob is working and creating the database records but it looks like its getting cut off only a small way through the insert.
This cut off is more dramatic the larger the image.

e.g.

 

I've updated the pbodb170.ini PBMaxBlobSize under each of the database sections and also included it in the database script

 

INI:
PBMaxBlobSize='1073741824'
PBMaxTextSize='1073741824'
Case IS_USE_SCRIPT							

	as_dbms			= "SNC SQL Native Client(OLE DB)"
	as_database		= ""
	as_userid		= ""
	as_dbpass		= ""
	as_logid		= "myDBbUserID"
	as_logpass		= "myDBUserPassword"
	as_server		= "myDbServer"
	as_dbparm		= "Database='MyDB';PBMaxBlobSize=1073741824"
	as_lock			= ""
	as_autocommit	= "true"

 

Database Table is in MS SQL 2014 Express


The field in the database is varbinary(max)

This is the code being used to save the blob to the database

 

Long 		l_file_handle, ll_blob_id
blob   		l_blob_file
str_response 	l_str_response
String 		ls_error

SQLCA.AutoCommit = TRUE

// Get File Handle
l_file_handle = FileOpen(as_filepath, StreamMode!)

IF l_file_handle  0 THEN
		COMMIT USING SQLCA;
	Else
		l_str_response.success = false
		l_str_response.message = 'Cannot upload blob to database.' 						+&
											'SQL error ' + String(SQLCA.SQLDBCode) + ' ' 	+&
											 SQLCA.SQLErrText
		return l_str_response
	END IF

ELSE
	l_str_response.success = false
	l_str_response.message = 'Cannot get handle on file'
	return l_str_response
END IF

l_str_response.success = true
l_str_response.message = ''
return l_str_response

 

Any ideas?
