API reference for the Amazon Redshift Python connector

Following, you can find a description of the Amazon Redshift Python connector API operations.

redshift_connector

Following, you can find a description of the redshift_connector API operation.

connect(user, database, password[, port, …])

Establishes a connection to an Amazon Redshift cluster. This function validates user input, optionally authenticates using an identity provider plugin, and then constructs a connection object.

apilevel

The DBAPI level supported, currently "2.0".

paramstyle
str(object=’’) -> str str(bytes_or_buffer[, encoding[, errors]]) -> str

The database API parameter style to use globally.

Connection

Following, you can find a description of the connection API operations for the Amazon Redshift Python connector.

__init__(user, password, database[, host, …])

Initializes a raw connection object.

cursor

Creates a cursor object bound to this connection.

commit

Commits the current database transaction.

rollback

Rolls back the current database transaction.

close

Closes the database connection.

execute(cursor, operation, vals)

Runs the specified SQL command. You can provide the parameters as a sequence or as a mapping, depending upon the value of redshift_connector.paramstyle.

run(sql[, stream])

Runs the specified SQL command. Optionally, you can provide a stream for use with the COPY command.

xid(format_id, global_transaction_id, …)

Create a transaction ID. Only the global_transaction_id parameter is used in postgres. format_id and branch_qualifier are not used in postgres. The global_transaction_id can be any string identifier supported by postgres that returns a tuple (format_id, global_transaction_id, branch_qualifier).

tpc_begin(xid)

Begins a TPC transaction with a transaction ID xid consisting of a a format ID, global transaction ID, and branch qualifier.

tpc_prepare

Performs the first phase of a transaction started with .tpc_begin.

tpc_commit([xid])

When called with no arguments, .tpc_commit commits a TPC transaction previously prepared with .tpc_prepare().

tpc_rollback([xid])

When called with no arguments, .tpc_rollback rolls back a TPC transaction.

tpc_recover

Returns a list of pending transaction IDs suitable for use with .tpc_commit(xid) or .tpc_rollback(xid).

Cursor

Following, you can find a description of the cursor API operation.

__init__(connection[, paramstyle])

Initializes a raw cursor object.

insert_data_bulk(filename, table_name, parameter_indices, column_names, delimiter, batch_size)

Runs a bulk INSERT statement.

execute(operation[, args, stream, …])

Runs a database operation.

executemany(operation, param_sets)

Prepares a database operation, and then runs it for all parameter sequences or mappings provided.

fetchone

Fetches the next row of a query result set.

fetchmany([num])

Fetches the next set of rows of a query result.

fetchall

Fetches all remaining rows of a query result.

close

Closes the cursor now.

__iter__

A cursor object can be iterated to retrieve the rows from a query.

fetch_dataframe([num])

Returns a dataframe of the last query results.

write_dataframe(df, table)

Writes the same structure dataframe into an Amazon Redshift database.

fetch_numpy_array([num])

Returns a NumPy array of the last query results.

get_catalogs

Amazon Redshift doesn't support multiple catalogs from a single connection. Amazon Redshift only returns the current catalog.

get_tables([catalog, schema_pattern, …])

Returns the unique public tables which are user-defined within the system.

get_columns([catalog, schema_pattern, …])

Returns a list of all columns in a specific table in an Amazon Redshift database.
