OLAP分析應用(十一)-動態生成sq
動態插入語句：
拼前半段：前半段語句在佈局表當中，已經存在了（設計界面的時候，就生成好了）。
拼插入sql語句後半段：關鍵是順序還要和插入前半段字段順序一致，其實，我們在comm_doc_layout中也有定義：
根據comm_doc_layout表中maincols中定義的順序，循環取得相關的值，代碼如下：
DocLayout layout = (DocLayout) cacheHelper.getObjectInCache(Constants.CACHE_LAYOUT,
new DocLayout_Key(true), Integer.parseInt(layoutId));
StringBuffer sql = new StringBuffer(layout.getMainsql() + "(");//插入語句的前半段
String[] cols = layout.getMaincols().split(",");//界面已保存的所有字段
List<BillArrObject> objs = this.exchange2Codes(list);//轉換得到所有數據元code
//保存主表
for (String col : cols) {//循環界面已保存的所有字段與傳來的list拼湊後半段sql
boolean f = true;
for (BillArrObject obj : objs) {
if (col.equals(obj.getName())) {
sql.append(this.exchange2str(user, obj, newGuid) + ",");//轉換成值
f = false;
}
}
if (col.equals("GUID") && f) {
String s = CreateGUID.GenerateGUID();
sql.append("'" + s + "',");
newGuid = s;
}
}
StringBuffer sql2 = new StringBuffer(sql.substring(0, sql.length() - 1));//去掉最後的逗號
sql2.append(")");
Query query = this.getCurrentSession().createSQLQuery(sql2.toString());
query.executeUpdate();
不過，取得值根據類型要進行一些轉換，如對日期進行格式化、數字進行必要的檢查判斷、字符串進行必要的轉換（主要是轉自然鍵值）、字符類型插入要加上前後引號等，代碼如下：
/***
* 判斷數據元類型並返回相應的字符串
* @param ecode
* 字符串返回'XX',數字返回XX，日期返回to_date('xx','yyyy-mm-dd hh24:mi:ss')
*/

至於更新，和插入是一樣的，不過得先刪除原來的記錄。

動態刪除
一個要點是找到要刪除的表：路徑爲：佈局對象-->數據集--->要刪除的表 拼接到sql當中
要刪除細表，要找到這個細表，路徑爲 主表數據集對象--->主細表關係對象-->關聯數據元
//根據佈局表找到數據集id
String setid = layout.getBillsetid();
//根據數據集id從緩存當中取得數據集對象
ds = (DataSet) cacheHelper.getObjectInCache(Constants.CACHE_DATA_SET, new DataSet_Key(true), setid);
//刪除主表
sql = "delete from " + ds.getScode() + " where " + FieldEnum.GUID.getFieldCode() + "='" + obj.getValue() + "'";
....
//找到主細關係表 進一步刪除細表當中數據
DataSet2DataSet s2s = (DataSet2DataSet) cacheHelper.getObjectInCache(
Constants.CACHE_DATA_SET2SET, new DataSet2Set_RelationId_Key(true), setid);
DataSet dds = (DataSet) cacheHelper.getObjectInCache(Constants.CACHE_DATA_SET,
new DataSet_Key(true), s2s.getSetid());//細表
DataElement de = (DataElement) cacheHelper.getObjectInCache(Constants.CACHE_DATA_ELEMENT,
new DataElement_Key(true), s2s.getElementid());//關聯數據元
String sql2 = "delete from " + dds.getScode() + " where " + de.getEcode() + "= '" + oldGuid + "'";//刪除細表
query = this.getCurrentSession().createSQLQuery(sql2);
query.executeUpdate();//執行刪除細表
