code: public static String logicDeleteColumnEqualsValue(Class<?> entityClass, boolean isDeleted) {
          EntityColumn logicDeleteColumn = SqlHelper.getLogicDeleteColumn(entityClass);
  
          if (logicDeleteColumn != null) {
              return logicDeleteColumnEqualsValue(logicDeleteColumn, isDeleted);
          }
  
          return "";
      }
docs: 返回格式: column = value
  <br>
  默认isDeletedValue = 1  notDeletedValue = 0
  <br>
  则返回is_deleted = 1 或 is_deleted = 0
  <br>
  若没有逻辑删除注解，则返回空字符串
  
  @param entityClass
  @param isDeleted   true 已经逻辑删除  false 未逻辑删除
