Nico de Groot and Raul Monares, thank you! I tested loading files less 64kb
and thats files was loaded. On my work we will use folder "uploads" for
store files.
But I don't understan why operation INSERT is working not in all cases.
There are two tables 'test' and 'bin_files'. Both tables have ge
The problem with the Firebird adapter is that it inserts blobs as base64
strings directly in an INSERT statement instead of using the stream
mechanism that Firebird provides. There's a reported bug about
this: https://github.com/web2py/web2py/issues/666. At this time, there's no
workaround.

I added blob to the fieldname because in my code DAL checks for reserved
SQL names. DATA is not allowed in some databases

Nico de Groot, thank you for example and attention! I already have crud
form and that form work. It load files in folder 'uploads'. I want to save
that files in database now. I sure that
stream=open(filepath + '\\' + i.file, 'rb')
and
stream.read()
made a long base64 string because I saw it on s
Take into account that the Firebird DAL adapter has a 64kb limit for
inserting blobs.

Minimal example using web2py DAL as a script. I'm not using firebird but
your example with the string shows that the storage in a blob is working in
firebird (Note that a python string is saved as binary data in a blob). In
a webapp, move code to model file and to a controller, or use a form to
That 'example' isn't work too(((. Can anyone advice how can I insert data
in blob field.
There are one interesting thing. This code is working.
db_xml.define_table('bin_files',
Field('id','integer'),
Field('PARENT'),
Field('SRC_FILENAME')
I found only one working example.
tables.py
db_xml.define_table('bin_files',
Field('id','integer'),
Field('PARENT'),
Field('SRC_FILENAME'),
Field('DATA', 'blob'),
primarykey=['id','PARENT'],
I found example:
tables.py
db_xml.define_table('test',
Field('NAME', 'string'),
Field('FILE', 'string')
)
default.py
db_xml.test.insert(NAME='something', FILE='somthing')
But it's not working, becouse generator not defined. In database I created
generator and trigge

You don’t need to use sqlexecute(), insert can handle multiple fields. But you
do need to separate them with comma. In the field definitions you need to add
the field type otherwise the default type is assumed (string). See the DAL
documentation for details.

Thank you, as I understand web2py function INSERT have only one argument
and if I want to pass 2 or more variables I should use something else?
I have read about executesql and use it for inserting some variables like
that: db.executesql('INSERT INTO table (var1, var2, var3) VALUES (1, 2, 3)')

If web2py didn't create the generator and trigger, you can do it manually
with this DDL
CREATE GENERATOR GENID_XML_FILES;
SET TERM !! ;
CREATE TRIGGER XML_FILES_BI FOR XML_FILES
ACTIVE BEFORE INSERT POSITION 0
AS
DECLARE VARIABLE tmp DECIMAL(18,0);
BEGIN
IF (NEW.ID IS NULL) THEN
NEW.ID = G
