A learner here. This has to be esasy but I cannot figure it out.
这是一个学习者。这必须是安逸的,但我无法弄清楚。
I have a table like this:
我有这样一张桌子:
ID -- NAME -- CHOICE
1 -- John -- book
2 -- Matt -- pen
3 -- Linda -- bag
.
.
What would be the script to turn all the data in column CHOICE to null?
将CHOICE列中的所有数据转换为null的脚本是什么?
Thanks a ton
万分感谢

You'd use an UPDATE statement, without a WHERE clause (so it updates every single row)
你使用UPDATE语句,没有WHERE子句(所以它更新每一行)
UPDATE YourTable
SET Choice = NULL
