Python API#

To begin a querying session in EvaDB, obtain a connection with a cursor using connect and cursor functions. After getting the cursor, you can run queries with the query function in this manner:

# Import the EvaDB package
import evadb

# Connect to EvaDB and get a database cursor for running queries
cursor = evadb.connect().cursor()

# List all the built-in functions in EvaDB
print(cursor.query("SHOW UDFS;").df())

connect([evadb_dir, sql_backend])

Connects to the EvaDB server and returns a connection object.


Retrieves a cursor associated with the connection.


Executes a SQL query.


Returns the result as a pandas DataFrame.


It is important to call df to run the actual query and get the output dataframe.

cursor.query("...") only construct the query and not run the query. cursor.query("...").df() will both construct and run the query.
