APEX 5 Give me Interactive Reports

One of the statements of direction for APEX 5 is multiple interactive reports on a single page.

Multiple Interactive Reports – Allow any number of Interactive Reports to be defined on a single page.

So, time to explore that functionality.

One pattern I've used in the past is loading particular saved reports (rather than the default primary report). You may have some pre-defined filters, a row highlight, specific columns. So for demonstrations, I've built an IR on the emp table.

Then I go and apply some filters, and save an alternate report:




Then in the page designer assign an alias to that report.





As you can see, that allows me to enter in the request portion of the URL: IR_SAL_TOTAL. However, if we add a second IR to the page and try to access that saved report, we would receive an error "Report does not exist". This is because it tries to find that that report name in both IR's.

To get around this, you MUST set a static ID property for your IR regions. Then the request portion of the URL would become: IR[<static ID>]_<ALIAS>. So I gave a static id: empIr, thus the request portion would be: IR[empIr]_SAL_TOTAL, to link to the report I previously saved.



The same concept applies to filtering your IR in the URL. The supported URL operations can be reviewed in the (beta) docs:

  • C = Contains
  • EQ = Equals (this is the default)
  • GTE = Greater than or equal to
  • GT = Greater Than
  • LIKE = SQL Like operator
  • LT = Less than
  • LTE = Less than or equal to
  • N = Null
  • NC = Not Contains
  • NEQ = Not Equals
  • NLIKE = Not Like
  • NN = Not Null
  • NIN = Not In (escape the comma separated values with backslash, \)
  • IN = In (escape the comma separated values with backslash, \)
  • ROWFILTER = Row Text Contains (this searches all columns displayed in the report with type STRING or NUMBER)

So, in the itemNames portion of the URL, you would spacify IR[<static id>]<operator as above>_<column>. So for example, if we wanted employees with a salary greater than 2000 we would use IR[empIr]GT_SAL giving us a URL like so:

f?p=101:1:12313123::::IR[empIr]GT_SAL:2000
