- teradataml.dataframe.dataframe.DataFrame.create_view = create_view(self, view_name, schema_name=None)
- Creates a view from the DataFrame object in the specified schema.
As teradataml creates views, internally for operations, which will be garbage
collected during remove_context(), this function helps the user to persist the
DataFrame as a view.
Note:
The persisted view can be used across sessions and can be accessed
using the view_name and schema_name.
PARAMETERS:
view_name:
Required Argument.
Specifies the name of the view to be persisted.
Types: str
schema_name:
Optional Argument.
Specifies the schema name where the view is to be persisted.
Note:
If the schema_name is not provided, the current database will be used.
Types: str
RETURNS:
Persisted teradataml DataFrame.
RAISES:
TeradataMlException
EXAMPLES:
# Load the data to run the example.
>>> load_example_data("antiselect", ["antiselect_input"])
>>> antiselect_input = DataFrame.from_table("antiselect_input")
>>> antiselect_input
