Question

我目前正在尝试输出产品代码和移动，以显示我们销售的产品数量的完整历史记录。

我有两张表private void setLivestockAttribute( String attribute ) { String value = ""; // 1. Get a List of the Indices of Rows selected. ObservableList<Integer> selectedIndices = null; selectedIndices = FXCollections.observableList(tblView_Livestock.getSelectionModel().getSelectedIndices()); // If ONE or MORE rows have been selected. if ( selectedIndices.size() > 0 ) { // 2. Get the VALUE of the relevant ATTRIBUTE. switch (attribute) { case LM_Constant.BREED: value = LM_Utility.getChoice_Breed(); break; case LM_Constant.SEX: value = LM_Utility.getChoice_Sex(); break; case LM_Constant.HAS_CALF: value = LM_Utility.getChoice_HasCalf(); break; } // If there is a VALUE. if ( value.length() > 0 ) { ObservableList<LivestockModel> dataList = tblView_Livestock.getItems(); // 3. Update each Livestock record. DataStore.getInstance().updateLivestock(dataList, selectedIndices, attribute, value); // 4. Refresh the TableView to show changes. setLivestockData(); } } }和PUB.movement

我已经做到了这一点

PUB.product

生成的输出是：

SELECT   a."prod-code" AS productcode, count(*) AS Movement 
FROM     (SELECT   mov."tran-date", pro."prod-code"   
          FROM     PUB."movement" mov,            
                   PUB."product" pro   
          WHERE    mov.SKU=pro.SKU   
            AND      mov."move-type" = 'i'   
            AND      pro."prod-group" like 'SLA%') a 
GROUP BY a."prod-code"

我唯一的问题是，如果当时开具多个发票，它只会将发票计为1，而不是发票数量。 PRODUCTCODE | MOVEMENT 0490786 1 0500012 1 0566003 1 0566004 1 0650594 1 0920127 1 0920154 1 1000557M1 1 1000578M1m 19中有一个qty列。我无法将其与当前查询合并以输出正确的库存变动。

Answer 1

听起来你想要SUM()字段的qty而不是动作数量？试试这个：

Select pro."prod-code" As productcode, Sum(mov.qty) As Movement
  From PUB.movement As mov
  Inner Join PUB.product As pro On mov.SKU = pro.SKU
  Where mov."move-type" = 'i'
    And pro."prod-group" like 'SLA%'
  Group By pro."prod-code";
