Database Firebird.NET提供程序中是否存在可更新的结果集和记录集？

我昨天在.NET提供商那里试过Firebird。Firebird肯定会击败SQL Compact Edition。我对它的特点和精确性感到惊讶。但是当我在.NET提供程序中找不到可更新的记录集/结果集特性和函数时，我感到很难过。FBResultSet不包含任何内容，没有行添加、创建、修改，什么都不包含。任何人都知道Firebird的Ado.Net提供程序中是否存在此功能，因为没有文档。我希望得到帮助，因为我正在等待将Firebird集成到我的免费软件应用程序中。另外，如果有用于实现可更新记录集的替换函数，则返回ResultSet。请帮帮我

问候。

我去过那里，做完了，拿到了t恤。所以，当我感受到你的痛苦时，我会给你一些代码来帮助你

我使用存储过程（存储过程）来执行任何记录更新添加等操作。然后我编写了一个类包装器来调用存储过程

在这里输入代码

因此，使用存储过程的以下代码：

ALTER PROCEDURE SP_IU_BATCH (
    AUTYPE INTEGER,
    BATCHID INTEGER,
    MAT_BATCHID INTEGER,
    DOS DATE,
    FACILITYID INTEGER)
RETURNS (
    RTNIDX INTEGER)
AS
BEGIN
    IF (:AUTYPE = 0) THEN
    BEGIN
        FOR
            SELECT GEN_ID(GEN_BATCH_ID,1)
            FROM RDB$DATABASE
        INTO
            :RTNIDX
        DO
        BEGIN
            INSERT INTO BATCH (BATCHID, MAT_BATCHID, DOS, FACILITYID)
            VALUES (:RTNIDX, :MAT_BATCHID, :DOS, :FACILITYID);
        END
    END
    ELSE
    BEGIN
        UPDATE BATCH SET MAT_BATCHID=COALESCE(:MAT_BATCHID, MAT_BATCHID), DOS=COALESCE(:DOS, DOS),
        FACILITYID=COALESCE(:FACILITYID, FACILITYID)
        WHERE BATCHID=:BATCHID;
    END
END

这是很多代码，但我不得不用很难的方式来完成，结果很糟糕。我希望你能用这个来弥补你的差距，开始跑步。Firebird真的是一个很棒的数据库。

谢谢你的源代码。我不知道把什么放在哪里，以及如何调用特定函数来更新DataTable中的任何行。
