CData Python Connector for Apache Impala

Build 24.0.9060

Batch Processing

This Python connector also supports writing to the data source via batch processing, using the cursor object's executemany() method. This requires both a SQL statement string and a data frame of values that act as a series of parameters for executing the SQL statement.

Note that the connector does not support transactions. As with normal write operations, all SQL statements executed by this connector affect the data source immediately. Call the connection's commit() method following the execution.

Insert

The following example adds new records to the table:
cur = conn.cursor()
cmd = "INSERT INTO [CData].[Default].Customers (City, CompanyName) VALUES (?, ?)"
params = [["Jon Deere", "RSSBus Inc."], ["Jon Deere", "RSSBus Inc."]]
cur.executemany(cmd, params)
print("Records affected: ", cur.rowcount)
