pandas.read_sql — pandas documentation - PyData |
This function is a convenience wrapper around read_sql_table and read_sql_query (for backward compatibility). It will delegate to the specific function depending on the provided input. A SQL query will be routed to read_sql_query, while a database table name will be routed to read_sql_table.

This question is very old by now. pandas 0.10 is very old as well. In the newest version of pandas 0.16, the read_frame method has been depricated in favour of the read_sql. Even so, the documentation says that just like the read_csv function, it takes a parse_dates argument Pandas 0.16 read_frame
It seems the parse_dates argument appeared in 0.14, at the same time as read_frame was depricated. The read_sql function seems to be a rename of the read_frame, so just updating your pandas version to 0.14 or higher and renaming your function will give you access to this argument. Here is the doc for the read_sql function: Pandas 0.16 read_sql

data_frame["column"] = pandas.to_datetime(data_frame["column"])
should work by default but if not you can specify options. See the doc.

Working with SQL using Python and Pandas – Dataquest
April 9, 2023 - We’d need to manually add column heads, and manually parse the data. Luckily, the pandas library has an easier way, which we’ll look at in the next section. Before we move on, it’s good practice to close Connection objects and Cursor objects that are open. This prevents the SQLite database from being locked.

DEPR: pandas.io.sql.execute · Issue #50185 · pandas-dev/pandas
December 11, 2022 - After #49967, SQLDatabase accepts str, Engine, and Connection, but in SQLDatabase.__init__, a Connection is created if it was not passed in, and an ExitStack is created to clean up the Connection and Engine if necessary. Cleanup happens either in SQLDatabase.__exit__ or at the end of the generator which is returned by read_sql if chunksize is not None. What I'm not able to see is how to do the cleanup after the caller fetches the results of pandas.io.sql.execute.

Generating SQL Create Table from Pandas DataFrame | by OmniView. | Medium
February 4, 2024 - Of course you could use ETL tools, but let’s say you can’t. Let’s say you only want to use python. As I said earlier, you can use the to_sql() function to push data, but to the best of my knowledge, that table has to first exist before you can push data to it. That’s where the io.sql.get_schema() function comes in!
