Showing Buttons in Oracle Apex with Server Side Condition dependent on Page Item Value?

I am currently struggling with Oracle Apex, trying to show a Button, when the Value of a Page Item is greater than Zero (numeric).

Figured the Server Side Condition (SQL Expression) would be the best Idea and my SQL Code is:

    If :PAGE_ITEM > 0 then
      Return True;
    else
       Return False;
    End if;

I am however getting the error: ORA-06550: line 1, column 37: ORA-00920: invalid relational operator.

Using the Server-Side-Condition “Item = Value” with my Item selected and the Value being 0 did not work as well…

Answer

Your expression syntax is incorrect for “SQL Expression” type. It is appropriate for the “PL/SQL Function Body” type.

However, the most appropriate type for this in my opinion is “PL/SQL Expression”, with the simple expression:

:PAGE_ITEM > 0
