vDataFrame¶

In [ ]:

vDataFrame(input_relation: str,
           cursor = None,
           dsn: str = "",
           usecols: list = [],
           schema: str = "",
           empty: bool = False)

The vDataFrame is a Python object that allows you to prepare and explore your data without modifying it. When you make "changes" to your data, the vDataFrame records your modifications as SQL queries and sends them to your Vertica database which then aggregates and returns the final result. For each column of the relation, the vDataFrame creates a virtual column (vcolumn) which stores the column alias and all the user modifications to the column.

Parameters¶

Name	Type	Optional	Description
input_relation	str	❌	Relation (view, table, or temporary table) used to create the object. To get a specific schema relation, your string must include both the relation and schema: 'schema.relation' or '"schema"."relation"'. Alternatively, you can use the 'schema' parameter, in which case the input_relation must exclude the schema name.
cursor	DBcursor	✓	Vertica database cursor. For a cursor designed by Vertica, see vertica_python. For ODBC, see pyodbc. For JDBC, see jaydebeapi. For more information, see the utilities.vHelp function.
dsn	str	✓	Database DSN, including the OS File and DB credentials. VerticaPy will try to create a vertica_python cursor first. If it didn't find the library, it will try to create a pyodbc cursor. For more information, see the utilities.vHelp function.
usecols	list	✓	List of columns to use to create the object.
schema	str	✓	Relation schema. This can be used as an alternate way to specify the schema of a particular relation and allows you to create schemas and relations with periods (.) in their names.
empty	bool	✓	If true, the vDatFrame will be empty. This can be to used to create a custom vDataFrame without going through the initialization check.

Attributes¶

Name	Type	Description
_VERTICAPY_VARIABLES_	dict	Dictionary containing all the vDataFrame attributes. allcols_ind, int : Int to use to optimize the SQL code generation. columns, list : List of the vcolumns names. count, int : Number of elements of the vDataFrame (catalog). cursor, DBcursor : Vertica database cursor. display, dict : Dictionary to use to format the vDataFrame. dsn, str : Vertica database DSN. exclude_columns, list : columns to exclude from the final relation. history, list : vDataFrame history (user modifications). input_relation, str : Name of the vDataFrame. main_relation, str : Relation to use to build the vDataFrame (first floor). order_by, dict : Dictionary of all the rules to sort the vDataFrame. query_on, bool : If true, every query will be displayed. saving, list : List to use to reconstruct the vDataFrame. schema, str : Schema of the input relation. schema_writing, str : Schema to use to create temporary tables when needed. time_on, bool : If set to True, all the query elapsed time will be displayed. where, list : List of all the rules to filter the vDataFrame.
vcolumns	vcolumn	Each vcolumn of the vDataFrame is accessible by entering its name between brackets. For example to access to "myVC", you can write vDataFrame["myVC"].
