Question

所以我在C#中有一个程序从第三方程序访问旧的Firebird 1.5数据库。我所拥有的方法之一是通过id获取报价或项目的数据:(抱歉那里有一些葡萄牙语单词）

public static List<object> GetFollowUpData(int id, TipoFollowUp tipo)
    {
        var res = new List<object>();
        string q = tipo == TipoFollowUp.Orcamento
            ? "SELECT ('Q-' || c.CLIENT_CODE || q.CQUO_FNUMB) as Codigo, q.CQUO_NAME as Nome, q.CQUO_SENT as Data, q.CQUO_TOTAL as Total, c.CLIENT_NAME as Empresa, m.CCON_NAME as Contacto, ((CASE WHEN m.CCON_PHONE1 IS null then '' else m.CCON_PHONE1 end) || '/' || (CASE WHEN m.CCON_PHONE2 IS null then '' else m.CCON_PHONE2 end) || '/' || (CASE WHEN m.CCON_PHONE3 IS null then '' else m.CCON_PHONE3 end) || '/' || (CASE WHEN m.CCON_PHONE4 IS null then '' else m.CCON_PHONE4 end) || '/' || (CASE WHEN c.CLIENT_PHONE1 IS null then '' else c.CLIENT_PHONE1 end) || '/' || (CASE WHEN c.CLIENT_PHONE2 IS null then '' else c.CLIENT_PHONE2 end) || '/' || (CASE WHEN c.CLIENT_PHONE3 IS null then '' else c.CLIENT_PHONE3 end) || '/' || (CASE WHEN c.CLIENT_PHONE4 IS null then '' else c.CLIENT_PHONE4 end)) as Telefones FROM CMULTIQUOTES q, CLIENTS c, CCONTACTS m WHERE q.ID = @id AND c.CLIENT_ID = q.CLIENT_ID AND q.CLIENT_PM = m.CCON_ID"
            : "SELECT q.PROJ_CODE as Codigo, q.PROJ_NAME as Nome, q.PROJ_COMPLETED as Data, (select sum(j.CJOB_TOTAL) from CJOBS j where j.PROJ_ID = @id) as Total, c.CLIENT_NAME as Empresa, m.CCON_NAME as Contacto, ((CASE WHEN m.CCON_PHONE1 IS null then '' else m.CCON_PHONE1 end) || '/' || (CASE WHEN m.CCON_PHONE2 IS null then '' else m.CCON_PHONE2 end) || '/' || (CASE WHEN m.CCON_PHONE3 IS null then '' else m.CCON_PHONE3 end) || '/' || (CASE WHEN m.CCON_PHONE4 IS null then '' else m.CCON_PHONE4 end) || '/' || (CASE WHEN c.CLIENT_PHONE1 IS null then '' else c.CLIENT_PHONE1 end) || '/' || (CASE WHEN c.CLIENT_PHONE2 IS null then '' else c.CLIENT_PHONE2 end) || '/' || (CASE WHEN c.CLIENT_PHONE3 IS null then '' else c.CLIENT_PHONE3 end) || '/' || (CASE WHEN c.CLIENT_PHONE4 IS null then '' else c.CLIENT_PHONE4 end)) as Telefones FROM PROJECTS q, CLIENTS c, CCONTACTS m WHERE q.PROJ_ID = @id AND c.CLIENT_ID = q.CLIENT_ID AND q.CLIENT_PM = m.CCON_ID";
        using (var cmd = new FbCommand(q) {CommandType = CommandType.StoredProcedure})
        using (cmd.Connection = new FbConnection(ConnectionString))
        {
            cmd.Connection.Open();
            cmd.Parameters.Add("@id", id);
            using (FbDataReader reader = cmd.ExecuteReader())
            {
                while (reader.Read())
                {
                    res.Add(id); // ID
                    res.Add(reader[0]); // Código
                    res.Add(reader[1]); // Nome
                    res.Add(reader[2]); // Data
                    res.Add(reader[3]); // Total
                    res.Add(reader[4]); // Empresa
                    res.Add(reader[5]); // Contacto
                    res.Add(reader[6]); // Telefones
                    res.Add(tipo); // Tipo
                }
                reader.Close();
            }
            cmd.Connection.Close();
        }
        return res;
    }

这大部分时间都有效 - 但对于特定项目，它不会返回任何数据（项目编号8771）

我将第二个查询复制粘贴到FlameRobin中，将其连接到数据库并用8771替换查询中的@id，flameRobin返回我想要的数据。

因此，如果FlameRobin可以使用我的查询获取数据，为什么我的程序也不能获得它？在上面的My方法中，Reader.Read() imediatly返回false，并且我没有从该项目的数据库中获取数据。到目前为止，其他项目和报价在我检测到的情况下没有问题返回数据

有人有什么想法吗？

Answer 1

对不起大家只花了半个小时左右，最后弄清楚我在程序中使用我的开发/测试数据库副本（在VS下）并连接到FlameRobin中的生产副本。

tw数据库之间缺乏同步导致了这个

有问题的项目存在于生产副本中 - 因此FlameRobin正在展示它 - 但不是在程序使用的开发/测试副本中

抱歉

SQL命令不返回特定记录
