On every push button of the header the following code are written on when-button-pressed trigger:
begin if NVL (Get_block_property ( " Scott_emp ' , order_by), ' ename ASC ' ) = ' ename ASC ' then set_block_property ( ' scott_emp ' , order_by, ' ename desc ' "); Else set_block_property (' scott_emp ', order_by, ' ename ASC '); End if;Go_block (' scott_emp '); Execute_query; End;
Above example when I am getting the current setting of the block, I am reading it in Upper Case because it returns in upper case even if I am setting the property in lower case.
