在Rails4中将我的数据库从sqlite3切换到mysql时出现strftime错误

最近我将我的数据库从sqlite3更改为mysql.当我运行我的项目时,我在其中一个使用此查询的文件中收到此错误.

date = Date.today 1

@employees = Employee.where(“status =？AND strftime(‘％d /％m’,date_of_birth)=？”,“Active”,date.strftime(‘％d /％m’)

ActionView::Template::Error (Mysql2::Error: FUNCTION hrms_development.strftime does not exist: SELECT COUNT(*) FROM `employees` WHERE (status = 'Active' AND strftime('%d/%m', date_of_birth) = '28/03')):
    210:             
    211:               <% date = Date.today %>
    212:              <% @employees = Employee.where("status = ? AND strftime('%d/%m', date_of_birth) = ?", "Active" , date.strftime('%d/%m')) %>
    213:             <% if @employees.empty? %>
    214:              
    215:             <%else%>
    216:               <% @employees.each do |e| %>
  app/views/home/_group_admin.html.erb:213:in `_app_views_home__group_admin_html_erb___2522183600721478262_91627100'
  app/views/home/index.html.erb:17:in `_app_views_home_index_html_erb__2772204906267359422_86967120'



ActionView::Template::Error: Mysql2::Error: FUNCTION hrms_development.strftime does not exist: SELECT COUNT(*) FROM `employees` WHERE (status = 'Active' AND strftime('%d/%m', date_of_birth) = '28/03')

解决方法:

只需更换即可试用

<% @employees = Employee.where("status = ? AND strftime('%d/%m', date_of_birth) = ?", "Active" , date.strftime('%d/%m')) %>

同

<% @employees = Employee.where("status = ? AND DATE_FORMAT(date_of_birth,'%d/%m') = ?", "Active" , date.strftime('%d/%m')) %>
