cursor.execute("SELECT * FROM table_name") # Returns generator of results # Does not put result into memory. Iterates through rows in a streaming fashion. # DEPRECATED for row in cursor.iter_result(): # Do something with row # Use: for row in cursor: # Do something with row # Fetch all results rows = cursor.fetchall() # Fetch one results rows = cursor.fetchone() # Fetch multiple results rows = cursor.fetchmany(size=10) # Get list of column names cursor.col_names # Get column names mapped to data types cursor.col_types

Simplified Functions
# List Permissions ## Permissions are shown as a hierarchical tree structure ### Level 1 = Catalog, Level 2 = Schemas, Level 3 = Table Names permissions = cursor.permissions() print(permissions) # Check database connection results = cursor.is_connected() # List all catalogs rows = cursor.show_catalogs() # List all schemas rows = cursor.show_schemas("catalog_name") # List all tables rows = cursor.show_tables("catalog_name", "schema_name") # Get number of rows rows = cursor.table_stats(catalog="catalog_name", schema="schema_name", table="table_name")
