反引号用于表名或列名。如果您将值传递给 value(x,x,x) 中的参数及其字符串文字，请使用单引号，例如 'string value'

 public bool InsertGuildShare(string RoleName, int RoleID, double Share, int GuildID, int Rank, int FamilyID, string FamilyName)
            {
                MySQLConnection conn = null;
    
                try
                {
    
                    conn = this._Database.DBConns.PopDBConnection();
    
                    string cmdText = "Insert into t_guildshare(RoleID,Share,GuildID,RoleName,Rank,FamilyID,FamilyName) VALUES (" + RoleID + "," + Share + "," + GuildID + ",'" + RoleName + "'," + Rank + "," + FamilyID + ",'" + FamilyName + "')";
    
                    MySQLCommand cmd = new MySQLCommand(cmdText, conn);
    
                    cmd.ExecuteNonQuery();
    
                    GameDBManager.SystemServerSQLEvents.AddEvent(string.Format("+SQL: {0}", cmdText), EventLevels.Important);
    
                    cmd.Dispose();
                    cmd = null;
    
                    return true;
                }
                catch (Exception ex)
                {
                    LogManager.WriteLog(LogTypes.Guild, "BUG :" + ex.ToString());
    
                    return false;
                }
                finally
                {
                    if (null != conn)
                    {
                        this._Database.DBConns.PushDBConnection(conn);
                    }
                }
            }
