LOV with PL/SQL in APEX 4.0

Question

I want to create a LOV in APEX 4.0 with the help of PL/SQL block,but when I am pasting my PL/SQL block code in the List Of Values area and try to run it, it is showing me error "Rendering Page ITEM F300_P1510_PROJECT_TASK raised the following error: ORA-20001: Query must begin with SELECT or WITH" where F300_P1510_PROJECT_TASK is my LOV name.
Please help me how to fix this.

Hi,
The way to do this that comes to mind, and I know it works because I have done it, is rather long and uses Ajax
1. Create an On Demand Application Process that returns this as a string
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>2. Write a javascript function (HTML Header) that will
a. Make an Ajax call to the Application Process in step 1
b. replace the options in the select tag with the result of the ajax call
3. Call the js function in step 2 using onload from HTML Body Attribute.
The pure SQL PL/SQL way would be as follows:
a. Create a PIPELINED function that returns the display, return pairs of values
b. Use the above function in SELECT in the LOV
Maybe there is a simpler way, but it eludes me.
