class ifcpatch.recipes.Ifc2Sql.Patcher(file, logger, sql_type: SQLTypes = 'SQLite', host: str = 'localhost', username: str = 'root', password: str = 'pass', database: str = f'{DEFAULT_DATABASE_NAME}.sqlite', full_schema: bool = True, is_strict: bool = False, should_expand: bool = False, should_get_inverses: bool = True, should_get_psets: bool = True, should_get_geometry: bool = True, should_skip_geometry_data: bool = False)

Convert an IFC-SPF model to SQLite or MySQL.

Parameters:

  • sql_type – Choose between “SQLite” or “MySQL”

  • database – Database path to save the SQL database to (already existing or not). Could also be a directory, then the database will be stored using default filename (e.g. ‘database.sqlite’).

  • full_schema – if True, will create tables for all IFC classes, regardless if they are used or not in the dataset. If False, will only create tables for classes in the dataset.

  • is_strict – whether or not to enforce null or not null. If your dataset might contain invalid data, set this to False.

  • should_expand – if True, entities with attributes containing lists of entities will be separated into multiple rows. This means the ifc_id is no longer a unique primary key. If False, lists will be stored as JSON.

  • should_get_psets – if True, a separate psets table will be created to make it easy to query properties. This is in addition to regular IFC tables like IfcPropertySet.

  • should_get_geometry – Whether or not to process and store explicit geometry data as a blob in a separate geometry and shape table.

  • should_skip_geometry_data – Whether or not to also create tables for IfcRepresentation and IfcRepresentationItem classes. These tables are unnecessary if you are not interested in geometry.

Filter_glob database:

.db;.sqlite

# Convert to SQLite, SQLite databse will be saved to a temporary file.
sqlite_temp_filepath = ifcpatch.execute(
    {"input": "input.ifc", "file": model, "recipe": "Ifc2Sql", "arguments": ["sqlite"]}
