Trigger compiles but errors out during execution

Question

You guys wouldn't like this. Its about a trigger !
Below is a trigger i've found in OTN. I've a similair requirement. The below trigger will compile . But, during execution i get
ORA-00936: missing expression during executionI have this feeling that the last line in the INSERT statment is causing the issue.
create or replace trigger trg_test
before insert or update on central_dtls.emp_config
for each row
declare
v_schema varchar2(100);
v_sql_stat varchar2(32767);
begin
select schema_name into v_schema from central_dtls.master_config where company_id= :new.id;
                              v_sql := 'insert into ' ||v_schema||'..emp_config_local
                              company_id,
                              values
                               ||:new.col1||', '
                               ||:new.col2||', '
                               ||:new.lastcol||  ')';    ----- Potential issue in this line
exception
when others then ......;
end;
/I've tried the below things.
||:new.lastcol  ');';   --- Trigger Will not compile
||:new.lastcol||  ')';    --- Trigger Will compile , but, will get "ORA-00936: missing expression" during execution
||:new.lastcol|| ');';   --- Trigger Will compile , but, will get "ORA-00936: missing expression" during execution

Answer 1

You have:
                              v_sql := 'insert into ' ||v_schema||'..emp_config_local Try with:
                              v_sql := 'insert into ' ||v_schema||'.emp_config_local (only one dot between schema and table name :) )
