[英]ORACLE APEX 18 JET Chart Dynamic Series
I was using AnyChart for all my chart in Apex 5. Now that I upgraded to 18.2, AnyChart is now "legacy". 我在Apex 5中为所有图表使用AnyChart。现在,我升级到18.2,AnyChart现在是“旧版”。 So, I wanted to update my chart to use JET Chart.
因此,我想更新图表以使用JET图表。
My chart used "PL/SQL Function Body returning SQL Query". 我的图表使用“返回SQL查询的PL / SQL函数体”。 My PL/SQL Function body build my query dynamicaly and my number of series displayed may varied.
我的PL / SQL函数主体动态地建立了我的查询,并且显示的序列数可能有所不同。 As I don't know how many series I will have, I'm not able to set my series in my chart.
我不知道会有多少个系列,因此无法在图表中设置系列。
Here's my PL/SQL Function Body: 这是我的PL / SQL函数体:
DECLARE
l_selected APEX_APPLICATION_GLOBAL.VC_ARR2;
l_sql VARCHAR2(4000) := '';
BEGIN
--
-- Convert the colon separated string of values into a PL/SQL array
l_sql := l_sql || 'SELECT NULL link ';
l_sql := l_sql || ' ,year_month label ';
l_selected := APEX_UTIL.STRING_TO_TABLE(:P16_SELECT_LIST);
--
-- Loop over array to insert department numbers and sysdate
IF l_selected.count = 0 THEN
l_sql := l_sql || ' ,NULL "no data" ';
ELSE
FOR i IN 1..l_selected.count LOOP
l_sql := l_sql || ',MIN(DECODE(sqn, '''||l_selected(i)||''', srt_cnt, NULL)) "'||l_selected(i)|| CASE WHEN REGEXP_LIKE(TRIM(l_selected(i)), '^[[:digit:]]') THEN ' Sqn' ELSE NULL END||'"';
END LOOP;
END IF;
l_sql := l_sql || ' FROM flight_and_mmh t ';
l_sql := l_sql || ' WHERE snapshot_fk = :P27_SNAPSHOT_LIST ';
l_sql := l_sql || ' AND INSTR('':'' || :P16_SELECT_LIST || '':'' , '':'' || sqn || '':'') > 0 ';
l_sql := l_sql || ' GROUP BY t.year_month ';
l_sql := l_sql || ' ORDER BY t.year_month ';
RETURN l_sql;
END;
Theres no need to use dynamic sql for multiple series in apex nowadays. 如今,无需在顶点中对多个系列使用动态sql。
In the series region select: series => Source => Region Source 在系列区域中选择:series => Source => Region Source
Then put your sql query in the main region source code. 然后将您的sql查询放入主区域源代码中。
Back in the series => Column Maping, u need to choose the VALUE , the LABEL and the SERIES NAME with the respective columns of your query. 回到系列=>列映射中,您需要选择VALUE , LABEL和SERIES NAME以及查询的相应列。
