Question

does anybody have example how to use BLOB in SQLAlchemy?

Regards, Steve

Answer 1

From the documentation BINARY seems the way to go: http://docs.sqlalchemy.org/en/latest/dialects/mysql.html

class sqlalchemy.dialects.mysql.BLOB(length=None) Bases: sqlalchemy.types.LargeBinary

The SQL BLOB type.

__init__(length=None) Construct a LargeBinary type.

Parameters: length – optional, a length for the column for use in DDL statements, for those BLOB types that accept a length (i.e. MySQL). It does not produce a lengthed BINARY/VARBINARY type - use the BINARY/VARBINARY types specifically for those. May be safely omitted if no CREATE TABLE will be issued. Certain databases may require a length for use in DDL, and will raise an exception when the CREATE TABLE DDL is issued.
