在PostgreSQL表中創建插入，更新規則

Question

我試圖用插入和更新規則創建一個postgresql表，該規則可以使用戶自動插入信息或更新數據庫表上的現有信息。 當我嘗試在數據庫中運行SQL查詢以創建表時，我不斷收到此錯誤。 我嘗試遵循PostgreSQL 9.1中的文檔步驟。 它一直使我的一個主鍵表達式出現錯誤，表明我需要重新編寫它。 請有人看看這個腳本並幫幫我。 感謝您最寶貴的貢獻！

這是我的SQL腳本

 CREATE TABLE fieldtally1
  (fieldtally1_id serial NOT NULL,
  pipeno character varying,

  );
  Create rule fieldtally1_ins as on INSERT to fieldtally1
  Do Instead
  Insert into fieldtally1 values (

                New.ManualUser, 
                current_timestamp
                );

CREATE RULE fieldtally1_upd AS ON UPDATE TO fieldtally1
    DO INSTEAD
    UPDATE fieldtally1
    SET PIPENO = New.pipeno,
    wthick = New.wthick,
    heatno1 = New.heatno1,
    pipeno2 = New.pipeno2,
    heatno2 = New.heatno2,
    Djointno = New.Djointno,
    ContractorNo = New.ContractorNo,
    measuredlength = New.measuredlength,
    New.serialno = New.serialno,
    coatingtype = New.coatingtype,
    coatingno = New.coatingno,
    mnfcno = New.mnfcno,
    factorylength = New.factorylength,
    pipeod_in = New.pipeod_in,
    pipeod_mm = New.pipeod_mm,
    pipeweight = New.pipeweight,
    pipegrade =  New.pipegrade,
    ManualUser = New.ManualUser 
    WHERE pipeno = OLD.pipeno;      

CREATE RULE fieldtally1_del AS ON DELETE TO fieldtally1
    DO INSTEAD
    DELETE FROM fieldtally1
     WHERE pipeno = OLD.pipeno;

這是我運行腳本時遇到的錯誤

注意：CREATE TABLE將為串行列“ fieldtally1.fieldtally1_id”創建隱式序列“ fieldtally1_fieldtally1_id_seq”注意：CREATE TABLE / PRIMARY KEY將為表“ fieldtally1”創建隱式索引“ fieldtally1_pkey”錯誤：列“ fieldtally1_id”是整數類型，但表達式類型的字符類型隨行而異。LINE 34：New.pipeno，^提示：您將需要重寫或強制轉換表達式。

*** 錯誤 ** *

錯誤：“ fieldtally1_id”列的類型為整數，但表達式的類型因字符而異SQL狀態：42804提示：您將需要重寫或強制轉換表達式。 字元：1024

Answer 1

如果您的插入內容與該列不完全匹配，則需要指定它們。 您的更新包括一個“新”。 在serialno的左側：在http://sqlfiddle.com/#!1/c9ef3/1/0中有效

用戶GO-因此sql在最后一次執行之前將不檢查評估
