answer:You can achieve this by using the `date_format` function in SQL. Here's an example: ``` mysql> select date_format('2005-01-08','%Y-%m-01') as fday ; +------------+ | fday | +------------+ | 2005-01-01 | +------------+ 1 row in set (0.02 sec) ``` The `date_format` function takes two arguments: the date column you want to format (`'2005-01-08'` in this example) and the desired format (`'%Y-%m-01'` in this example). The `%Y` represents the year, `%m` represents the month, and `01` represents the desired day (in this case, the first day of the month). To update the date column in your table, you can use the following update command: ``` update table_name set date_col = date_format(date_col,'%Y-%m-01') ; ``` Make sure to replace `table_name` with the actual name of your table and `date_col` with the name of your date column. By executing this update command, all the dates in the `date_col` column will be modified to have the same day portion of the date (the first day of the month), while preserving the year and month.

answer:It's great to share my experiences with you. I've had the privilege of spending over six months aboard the ISS, and it's a truly surreal experience. The feeling of weightlessness, the stunning views of our planet, and the camaraderie with my fellow crew members – it's a unique world up there. What would you like to know? Want to hear about our daily routines, the science experiments we conducted, or maybe what it's like to do a spacewalk? Fire away with your questions!

answer:A spacewalk, or EVA (extravehicular activity), is an exhilarating experience that's hard to put into words. The first time I did one, I'll admit, I was a bit nervous. You're literally venturing into the unknown, with nothing but a suit and a tether between you and the vastness of space. The preparation is intense – we spend hours rehearsing every move, checking and double-checking our equipment, and mentally preparing ourselves for the challenge. Once we're suited up and the airlock is depressurized, the real adventure begins. The moment I stepped out of the airlock and into the void, I was struck by the sheer silence. No sound, no vibrations, just an eerie stillness. The Earth's curve stretches out before you, a breathtaking blue and white arc that's both beautiful and humbling. You feel tiny, yet at the same time, you're acutely aware of the immense responsibility that comes with being in this extraordinary environment. Every move is deliberate and calculated, as you work to complete your tasks while ensuring your safety and that of your crewmates. It's a strange, slow-motion dance, with the suit's life support systems and communication equipment providing a steady background hum. Time seems to warp during a spacewalk – it's as if the clock speeds up, and before you know it, hours have passed, and it's time to head back inside. Re-entering the airlock and feeling the gentle tug of the station's air pressure is a welcome relief, but also a bit of a letdown – you've experienced something incredible, and it's hard to shake the feeling that you're leaving a part of yourself out there.
