擴充表格 extending-a-table

若要擴充 nms:recipient 綱要收件者表格,請套用下列程式:

  1. 建立擴充功能綱要(cus:extension)使用下列資料:

    code language-none
    <srcSchema mappingType="sql" name="extension" namespace="cus" xtkschema="xtk:srcSchema" extendedSchema="nms:recipient">
      <enumeration basetype="string" default="area1" name="area">
        <value label="Zone 1" name="area1"/>
        <value label="Zone 2" name="area2"/>
      </enumeration>
    
      <element name="extension">
        <dbindex name="area">
          <keyfield xpath="location/@area"/>
        </dbindex>
    
        <attribute label="Loyalty code" name="fidelity" type="long"/>
        <element name="location">
          <attribute name="area" label="Purchasing zone" type="string" length="50" enum="area"/>
        </element>  </element>
    </srcSchema>
    

    在此範例中,索引欄位(逼真度)新增了,且 位置 元素(已存在於 nms:recipient 結構描述)以列舉欄位(區域)。

    note important
    IMPORTANT
    請記得新增 extendedSchema 屬性以參考擴充功能綱要。
  2. 檢查擴充結構描述是否為 nms:recipient 結構描述以及其他資料存在:

    code language-none
    <schema dependingSchemas="cus:extension" mappingType="sql" name="recipient" namespace="nms" xtkschema="xtk:schema">
      ...
      <enumeration basetype="string" default="area1" name="area">
        <value label="Zone 1" name="area1"/>
        <value label="Zone 2" name="area2"/>
      </enumeration>
      ...
      <element autopk="true" name="recipient" sqltable="NmsRecipient">
        <dbindex name="area">
          <keyfield xpath="location/@area"/>
        </dbindex>
    
        ...
        <attribute belongsTo="cus:extension" label="Loyalty code" name="fidelity" sqlname="iFidelity" type="long"/>
        <element name="location">
          ...
          <attribute enum="area" label="Purchasing zone" length="50" name="area" sqlname="sArea" type="string"/>
        </element>
        ...
      </element>
    </schema>
    

    從資料庫更新精靈產生的SQL指令碼如下:

    code language-none
    ALTER TABLE NmsRecipient ADD iFidelity INTEGER;
    UPDATE NmsRecipient SET iFidelity = 0;
    ALTER TABLE NmsRecipient ALTER COLUMN iFidelity SET NOT NULL;ALTER TABLE NmsRecipient ALTER COLUMN iFidelity SET Default 0;
    ALTER TABLE NmsRecipient ADD sArea VARCHAR(50);
    CREATE INDEX NmsRecipient_area ON NmsRecipient(sArea);
    

連結的集合表格 linked-collection-table

本節說明如何建立連結至具有基數1-N之收件者表格的訂單表格。

排序表格來源結構描述:

<srcSchema label="Order" name="order" namespace="cus" xtkschema="xtk:srcSchema">
  <element autopk="true" name="order">
    <compute-string expr="@number" + '(' + ToString(@date) + ')'/>

    <attribute label="Number" length="128" name="number" type="string"/>
    <attribute desc="Order date" label="Date" name="date" type="datetime" default="GetDate()"/>
    <attribute desc="order total" label="Total" name="total" type="double"/>
    <element label="Recipient" name="recipient" revDesc="Orders associated with this recipient" revIntegrity="own" revLabel="Orders" target="nms:recipient" type="link"/>
  </element>
</srcSchema>

表格型別為 autopk ,以建立自動產生的主要索引鍵,供連結至收件者表格使用。

產生的結構描述:

<schema label="Order" mappingType="sql" name="order" namespace="cus" xtkschema="xtk:schema">
  <element autopk="true" label="Order" name="order" sqltable="CusOrder">
    <compute-string expr="ToString(@date) + ' - ' + @number"/>

    <dbindex name="id" unique="true">
      <keyfield xpath="@id"/>
    </dbindex>

    <key internal="true" name="id">
      <keyfield xpath="@id"/>
    </key>

    <dbindex name="recipientId">
      <keyfield xpath="@recipient-id"/>
    </dbindex>

    <attribute desc="Internal primary key" label="Primary key" name="id" sqlname="iOrderId" type="long"/>
    <attribute label="Number" length="128" name="number" sqlname="sNumber" type="string"/>
    <attribute desc="Order date" label="Date" name="date" sqlname="tsDate" type="datetime"/>
    <attribute desc="order total" label="Total" name="total" sqlname="Total" type="double"/>
    <element label="Recipient" name="recipient" revLink="order" target="nms:recipient" type="link">
      <join xpath-dst="@id" xpath-src="@recipient-id"/>
    </element>
    <attribute advanced="true" label="Foreign key of 'Recipient' link ('id' field)" name="recipient-id" sqlname="iRecipientId" type="long"/>
   </element>
</schema>

表格建立SQL命令檔如下:

CREATE TABLE CusOrder(dTotal DOUBLE PRECISION NOT NULL Default 0, iOrderId INTEGER NOT NULL Default 0, iRecipientId INTEGER NOT NULL Default 0, sNumber VARCHAR(128), tsDate TIMESTAMP Default NULL);
CREATE UNIQUE INDEX CusOrder_id ON CusOrder(iOrderId);
CREATE INDEX CusOrder_recipientId ON CusOrder(iRecipientId);
INSERT INTO CusOrder (iOrderId) VALUES (0);
NOTE
SQL命令INSERT INTO位於指令碼結尾,可讓您插入設為0的識別碼記錄,以模擬外部聯結。

擴充功能表格 extension-table

擴充表格可讓您擴充連結基數1-1之連結表格中現有表格的內容。

擴充功能表格的用途是避免表格中支援的欄位數限制,或最佳化資料佔用的空間(依需求使用)。

建立擴充功能表格結構(cus:feature):

<srcSchema mappingType="sql" name="feature" namespace="cus" xtkschema="xtk:srcSchema">
  <element autopk="true" name="feature">
    <attribute label="Children" name="children" type="byte"/>
    <attribute label="Single" name="single" type="boolean"/>
    <attribute label="Spouse first name" length="100" name="spouseFirstName" type="string"/>
  </element>
</srcSchema>

在收件者表格上建立擴充功能綱要,以新增基數1-1的連結:

<srcSchema extendedSchema="nms:recipient" label="Recipient" mappingType="sql" name="recipient" namespace="cus" xtkschema="xtk:srcSchema">
  <element name="recipient">
    <element desc="Features" integrity="own" label="Features" name="feature" revCardinality="single" revLink="recipient" target="cus:feature" type="link"/>
  </element>
</srcSchema>
NOTE
收件者表格和擴充功能表格之間連結的定義,必須從包含外部索引鍵的綱要填入。

建立擴充功能表格的SQL指令碼如下:

CREATE TABLE CusFeature(  iChildren NUMERIC(3) NOT NULL Default 0, iFeatureId INTEGER NOT NULL Default 0, iSingle NUMERIC(3) NOT NULL Default 0, sSpouseFirstName VARCHAR(100));
CREATE UNIQUE INDEX CusFeature_id ON CusFeature(iFeatureId);
INSERT INTO CusFeature (iFeatureId) VALUES (0);

收件者表格SQL更新指令碼如下:

ALTER TABLE NmsRecipient ADD iFeatureId INTEGER;
UPDATE NmsRecipient SET iFeatureId = 0;
ALTER TABLE NmsRecipient ALTER COLUMN iFeatureId SET NOT NULL;
ALTER TABLE NmsRecipient ALTER COLUMN iFeatureId SET Default 0;
CREATE INDEX NmsRecipient_featureId ON NmsRecipient(iFeatureId);

溢位表格 overflow-table

溢位表格是擴充表格(基數1-1),但要擴充之表格的連結宣告會填入溢位表格的綱要。

溢位表格包含要擴充之表格的外部索引鍵。 因此,不會修改要擴充的表格。 兩個表格之間的關係是要擴充之表格的主鍵值。

建立溢位表格綱要(cus:overflow):

<srcSchema label="Overflow" name="overflow" namespace="cus" xtkschema="xtk:srcSchema">
  <element name="overflow">
    <key internal="true" name="id">
      <keyfield xlink="recipient"/>
    </key>

    <attribute label="Children" name="children" type="byte"/>
    <attribute label="Single" name="single" type="boolean"/>
    <attribute label="Spouse first name" length="100" name="spouseFirstName" type="string"/>
    <element label="Customer" name="recipient" revCardinality="single" revIntegrity="own" revExternalJoin="true" target="nms:recipient" type="link"/>
  </element>
</srcSchema>
NOTE
溢位表格的主索引鍵是要擴充表格的連結(範例中為「nms:recipient」綱要)。

表格建立SQL命令檔如下:

CREATE TABLE CusOverflow(iChildren NUMERIC(3) NOT NULL Default 0, iRecipientId INTEGER NOT NULL Default 0, iSingle NUMERIC(3) NOT NULL Default 0, sSpouseFirstName VARCHAR(100));
CREATE UNIQUE INDEX CusOverflow2_id ON CusOverflow2(iRecipientId);

關係表 relationship-table

關係表格可讓您連結兩個具有基數N-N的表格。此表格僅包含要連結之表格的外部索引鍵。

群組之間關係表的範例(nms:group)和收件者(nms:recipient)。

關係表的來源結構描述:

<srcSchema name="rcpGrpRel" namespace="cus">
  <element name="rcpGrpRel">
    <key internal="true" name="id">
      <keyfield xlink="rcpGroup"/>
      <keyfield xlink="recipient"/>
    </key>

    <element integrity="neutral" label="Recipient" name="recipient" revDesc="Groups to which this recipient belongs" revIntegrity="own" revLabel="Groups" target="nms:recipient" type="link"/>
    <element integrity="neutral" label="Group" name="rcpGroup" revDesc="Recipients in the group" revIntegrity="own" revLabel="Recipients" revLink="rcpGrpRel" target="nms:group" type="link"/>
  </element>
</srcSchema>

產生的結構描述如下:

<schema mappingType="sql" name="rcpGrpRel" namespace="cus" xtkschema="xtk:schema">
  <element name="rcpGrpRel" sqltable="CusRcpGrpRel">
    <compute-string expr="ToString([@rcpGroup-id]) + ',' + ToString([@recipient-id])"/>
    <dbindex name="id" unique="true">
      <keyfield xpath="@rcpGroup-id"/>
      <keyfield xpath="@recipient-id"/>
    </dbindex>

    <key internal="true" name="id">
      <keyfield xpath="@rcpGroup-id"/>
      <keyfield xpath="@recipient-id"/>
    </key>

    <dbindex name="rcpGroupId">
      <keyfield xpath="@rcpGroup-id"/>
    </dbindex>
    <dbindex name="recipientId">
      <keyfield xpath="@recipient-id"/>
    </dbindex>

    <element integrity="neutral" label="Recipient" name="recipient" revLink="rcpGrpRel" target="nms:recipient" type="link">
      <join xpath-dst="@id" xpath-src="@recipient-id"/>
    </element>
    <attribute advanced="true" label="Foreign key of 'Recipient' link ('id' field)" name="recipient-id" sqlname="iRecipientId" type="long"/>

    <element integrity="neutral" label="Group" name="rcpGroup" revLink="rcpGrpRel" target="nms:group" type="link">
      <join xpath-dst="@id" xpath-src="@rcpGroup-id"/>
    </element>
    <attribute advanced="true" label="Foreign key of 'Group' link ('id' field)" name="rcpGroup-id" sqlname="iRcpGroupId" type="long"/>
  </element>
</schema>

表格建立SQL命令檔如下:

CREATE TABLE CusRcpGrpRel( iRcpGroupId INTEGER NOT NULL Default 0, iRecipientId INTEGER NOT NULL Default 0);
CREATE UNIQUE INDEX CusRcpGrpRel_id ON CusRcpGrpRel(iRcpGroupId, iRecipientId);
CREATE INDEX CusRcpGrpRel_recipientId ON CusRcpGrpRel(iRecipientId);

此使用案例示範如何使用現有的參考表格作為內建Adobe Campaign列舉機制(enum、userEnum或dbEnum)的替代方案。

您也可以使用現有的參考表格作為結構描述中的分項清單。 這可以透過在表格和參照表格之間建立連結,並新增屬性來達成 displayAsField="true".

在此範例中,參考表格包含銀行名稱與識別碼的清單:

<srcSchema entitySchema="xtk:srcSchema" img="cus:bank16x16.png" label="Bank" mappingType="sql" name="bank" namespace="cus"
xtkschema="xtk:srcSchema">
    <element img="cus:bank16x16.png" label="Banks" name="bank">
        <compute-string expr="@name"/>
        <key name="id">
            <keyfield xpath="@id"/>
        </key>
        <attribute label="Bank Id" name="id" type="short"/>
        <attribute label="Name" length="64" name="name" type="string"/>
     </element>
</srcSchema>

在使用此參考表的任何表格中,定義連結並新增 displayAsField="true" 屬性。

<element displayAsField="true" label="Bank" name="bank" target="cus:bank" type="link" noDbIndex="true"/>

使用者介面不會顯示連結,但會顯示欄位。 當使用者選取該欄位時,他們可以從參照表中選取值或使用自動完成功能。

  • 為了使其自動完成,您必須在參考表中定義計算字串。

  • 新增 noDbIndex="true" 屬性來防止Adobe Campaign在連結的來源表格中儲存的值上建立索引。
