SQL如何截断字符串
我有一列字符串，每个字符串包含一个城市、州和数字.
I have a column of strings with a city, state and number in each.
SPOKANE, WA 232/107
LAS VEGAS, NV 232/117
PORTLAND, OR 232/128
还有很多，但我想知道如何删除此列中的数字并仅显示城市和州，或者-甚至更好- 删除数字并将城市和州作为单独的列.
There are many more than just that, but I am wondering how either I could cut off the numbers in this column and just show the city and state or -even better- cut off the numbers and make city and state a separate column.
对于所有不同的记录，该列一直采用相同的格式.
The column is in the same format all the way down for all the different records.
谢谢！

无需为您完成所有工作...
Without doing all of the work for you...
城市:列的子字符串，从位置 0 到逗号的第一次出现 - 1.
状态:列的子字符串，从逗号第一次出现后的 2 个位置到下一个空格的位置......修剪.
City: A substring of the column from position 0, to the first occurence of a comma - 1.
State: A substring of the column from 2 positions after the first occurence of a comma, to the next position that is a space... trimmed.
