Plug-In: Tag Cloud Chart


It's a Tag Cloud Chart Plug-In. A tag cloud, otherwise known as a word cloud or weighted list, is a visual representation of text data. This chart is typically used to show keyword metadata (tags) on websites, or to visualize free form text. Tags are usually single words, and the importance of each tag, which is often based on its frequency, is shown with font size or color. It makes the visualize of complex data easy and understand it at a glance. This has been inspired by anychart.com.

Printing Page Numbers in RTF Template [Oracle BI Publisher]

Here I am giving an example to print the page numbers dynamically in the RTF (Rich Text Format) template. Step 1:  Go to page footer and copy and paste the below script.

CREATE TABLE emp   (     empno        NUMBER,     first_name   VARCHAR2(240),     last_name    VARCHAR2(240),     mgr          NUMBER,     deptno       NUMBER,     sal          NUMBER,     created_date TIMESTAMP (6),     comm         NUMBER,     hiredate     DATE,     JOB          VARCHAR2(240),     ename        VARCHAR2(240),     PRIMARY KEY (empno) USING INDEX ENABLE   ); /    INSERT INTO emp (empno, first_name, last_name, mgr,                   deptno, sal, created_date)         VALUES                 (1, 'Larry', 'Ellison', ,                  10, 5000, LOCALTIMESTAMP);   INSERT INTO emp (empno, first_name, last_name, mgr,                   deptno, sal, created_date)         VALUES                 (2, 'Juan', 'Juan', 1,  

Save Selected Interactive Grid Records into a Collection - Oracle APEX

Here I am giving an example to save selected interactive grid records into a oracle apex collection. Step 1: Create a new blank page. Note: Mine was page 20. You will need to update reference to " P20 " with your page number if it's different. Step 2: Create a new interactive grid report region to the page using below query. Set Static Id "EmpDetails" to the region. SELECT  *     FROM   ( SELECT  emp . empno ,                emp . ename ,                emp . JOB ,                dept . dname department ,                dept . loc  LOCATION ,                mgr . ename  manager ,                emp . hiredate ,                 nvl ( emp . sal , 0 )  salary ,                 nvl ( emp . comm , 0 )  commission            FROM  eba_demo_chart_emp emp ,                eba_demo_chart_dept dept ,                eba_demo_chart_emp mgr           WHERE  emp . deptno = dept . deptno             AND  emp . mgr      = mgr . empno  ( + )           ORDER   BY  emp . ename
