Passing values to APEX_UTIL.JSON_FROM_SQL

Question

What I'm trying to do in my OnDemand application process is something like:
declare
lv_ename varchar2(10) := 'BLAKE';
begin
APEX_UTIL.JSON_FROM_SQL('select empno,ename,job from emp where ename = '||lv_ename||'')
end;
What I get is:
ORA-20001: get_dbms_sql_cursor error ORA-20001: Invalid parsing schema for current workspace ID
from Application Express 3.1.2.00.02
-or-
ORA-20001: get_dbms_sql_cursor error ORA-00904: "BLAKE": invalid identifier
from Application Express 3.2.0.00.27
I get the same error message from Application Express 3.1.2.00.02 if I try passing a number rather than a varchar2 but Application Express 3.2.0.00.27 is OK with the number.
declare
lv_empno number := 7900;
begin
APEX_UTIL.JSON_FROM_SQL('select empno,ename,job from emp where empno = '||lv_empno||'');
end;
How do I get a varchar2 value into my WHERE clause?

Hello,
Your missing some quotes (but I don't know if this is the correct number of quotes. Print out the statement to see if it is constructed correctly. It should become:
select empno,ename,job from emp where ename = 'BLAKE'
APEX_UTIL.JSON_FROM_SQL('select empno,ename,job from emp where ename = '||'''||lv_ename||'''')
