Question

我已经将一个excel电子表格导入到sql server表中，如果我将一个单元格复制并粘贴到记事本中，例如它在单词后面包含很多空格

e.g。

require 'mechanize'
require 'json'
require 'open-uri'
require 'openssl'
require 'base64'
require 'time'

def fa(shared_secret)
      timestamp = Time.new.to_i
      math = timestamp / 30
      math = math.to_i
      time_buffer =[math].pack('Q>')

      hmac = OpenSSL::HMAC.digest('sha1', Base64.decode64(shared_secret), time_buffer)

      start = hmac[19].ord & 0xf
      last = start + 4
      pre = hmac[start..last]
      fullcode = pre.unpack('I>')[0] & 0x7fffffff

      chars = '23456789BCDFGHJKMNPQRTVWXY'
      code= ''
      for looper in 0..4 do
        copy = fullcode #divmod
        i = copy % chars.length #divmod
        fullcode = copy / chars.length #divmod
        code = code + chars[i]
      end
      puts code
      return code

end

def pass_stamp(username,password,mech)
      response = mech.post('https://store.steampowered.com/login/getrsakey/', {'username' => username})

      data = JSON::parse(response.body)
      mod = data["publickey_mod"].hex
      exp = data["publickey_exp"].hex
      timestamp = data["timestamp"]

      key   = OpenSSL::PKey::RSA.new
      key.e = OpenSSL::BN.new(exp)
      key.n = OpenSSL::BN.new(mod)
      ep = Base64.encode64(key.public_encrypt(password.force_encoding("utf-8"))).gsub("\n", '')
      return {'password' => ep, 'timestamp' => timestamp }
end

user = 'user'
password = 'password'

session = Mechanize.new { |agent|
  agent.user_agent_alias = 'Windows Mozilla'
  agent.follow_meta_refresh = true
  agent.add_auth('https://steamcommunity.com/tradeoffer/new/send/', user, password)
  agent.log = Logger.new("mech.log")
}

data = pass_stamp(user,password, session)
ep = data["password"]
timestamp = data["timestamp"]
session.add_auth('https://steamcommunity.com/tradeoffer/new/send/', user,  ep)

send = {
      'password' => ep,
      'username' => user,
      'twofactorcode' =>fa('twofactorcode'), #update
      'emailauth' => '',
      'loginfriendlyname' => '',
      'captchagid' => '-1',
      'captcha_text' => '',
      'emailsteamid' => '',
      'rsatimestamp' => timestamp,
      'remember_login' => 'false'
}

login = session.post('https://store.steampowered.com/login/dologin', send )
responsejson = JSON::parse(login.body)
if responsejson["success"] != true
      puts "didn't sucded"
      puts "probably 2fa code time diffrence,  retry "
      exit
end

responsejson["transfer_urls"].each { |url|
      getcookies = session.post(url, responsejson["transfer_parameters"])
}


## SET COOKIE FOR STEAM COMMUNITY.COM
steampowered_sessionid = ''
session.cookies.each { |c|
      if c.name == "sessionid"
            steampowered_sessionid = c.value
            puts c.domain
      end
}
cookie = Mechanize::Cookie.new :domain => 'steamcommunity.com', :name =>'sessionid', :value =>steampowered_sessionid, :path => '/'
session.cookie_jar << cookie
sessionid = steampowered_sessionid
### END SET COOKIE
offer_link = 'https://steamcommunity.com/tradeoffer/new/?partner=410155236&token=H-yK-GFt'
token = offer_link.split('token=', 2)[1]
theirs = [{"appid" => 753,"contextid"=> "6","assetid" => "6705710171","amount" => 1 }]
mine =  []
params = {
      'sessionid' => sessionid,
      'serverid' => 1,
      'partner' => '76561198370420964',
      'tradeoffermessage' => '',
      'json_tradeoffer' => {
            "newversion" => true, ## FIXED newversion to avoid 400 BAD REQUEST
           "version" => 4,
           "me" => {
                "assets" => mine, #create this array
                "currency" => [],
                "ready" => false
           },
           "them" => {
                 "assets" => theirs, #create this array
                 "currency" => [],
                 "ready" => false
            }
      }.to_json, # ADDED TO JSON TO AVOID 400 BAD REQUEST
      'captcha' => '',
      'trade_offer_create_params' => {'trade_offer_access_token' => token}.to_json ## ADDED TO JSON FIX TO AVOID ERROR 400 BAD REQUEST
}

begin
      send_offer = session.post(
       'https://steamcommunity.com/tradeoffer/new/send',
        params,
        {'Referer' =>  'https://steamcommunity.com/tradeoffer/new', 'Origin' => 'https://steamcommunity.com' } ##FIXED THIS
      )
      puts send_offer.body
rescue Mechanize::UnauthorizedError => e
      puts e
      puts e.page.content
end

但它应该只是：

"absconding

"

另一个例子：

"absconding"

就像换行符一样，我可以修剪该列中的所有空格，但是有很多条目是句子

有没有办法摆脱最后一个单词后的所有空格？

Answer 1

您可以使用TRIM()功能。 MySQL TRIM（）函数在从给定字符串中删除所有前缀或后缀后返回一个字符串。

public class NodeDetails {
private String typeMessage;
private String nodeName;
private String ip;
private String nPort;
private int capacity;
private String resources;

get and set methods for all the variables as well....

}

示例：

TRIM([{BOTH | LEADING | TRAILING} [remstr] FROM ] str)

输出：

SELECT TRIM(' trim ');

对于您的情况，数据已经在数据库中，并且您想要清理空格或任何其他不需要的字符，您可以使用trim语句中的TRIM函数：

UPDATE

注意 - 如果您只想删除前导或尾随空格，可以使用其他字符串函数：UPDATE tblGloss SET TITLE = TRIM(Replace(Replace(TITLE,'\t',''),'\n',''));和LTRIM。

Answer 2

您可以合并replace以删除换行符和rtrim以删除右侧的空格：

declare @x varchar(200)
set @x='absconding

'
select rtrim(replace(replace(@x,CHAR(10),''),CHAR(13),''))

SQL导入 - 单元格包含空格
