bro it is not working on string format coz of the missing quotes. e.g. 'smith' or smith. so the quoted string will be compared. in set_block_property u have to include extra quotes on the variable. e.g.
set_block_property('emp',default_where,'where ename='''||:emp.ename||'');
or with conditional statement
set_block_property('emp',default_where,'where ename='''||:emp.ename||''' and dname='''||dept.deptno||'');
there i included two extra qoutes before joining ename and in the an extra quote to complete to string. if u would like to debug at runtime to show if the qouted string condition is proper then assign the where clause to a variable and message it up.
like
myvariable:='where ename='''||:emp.ename||'';
message(myvariable);
message(myvariable);
set_block_property('emp',default_where,myvariable);
after the string is quoted properly the execute query will work fine, also use the function upper or lower to compare strings.
