Triggers in Stored Procedures

Question

Hi,
I am trying to execute the following procedure:
create or replace procedure create_view_trigger (viewname IN varchar2, triggername IN
varchar2, emp_number IN emp.empno%TYPE ) is
sql_statement varchar2(200);
view_name varchar2(100);
sql_statement1 varchar2(10000);
trigger_name varchar2(100);
begin
view_name := viewname;
sql_statement := 'create or replace view ';
sql_statement := sql_statement || view_name ||' as select * from emp';
dbms_output.put_line('View is created');
execute immediate sql_statement;
trigger_name := triggername;
sql_statement1 := 'create or replace trigger ';
sql_statement1 := sql_statement1 || trigger_name ||' instead of update on ';
sql_statement1 := sql_statement1 || view_name ||' referencing new as n for each row';
sql_statement1 := sql_statement1 || ' DECLARE employeenumber emp.empno%TYPE;';
sql_statement1 := sql_statement1 || ' BEGIN';
sql_statement1 := sql_statement1 || ' employeenumber = emp_number;';
sql_statement1 := sql_statement1 || ' UPDATE employee_info SET sal = sal+20';
sql_statement1 := sql_statement1[i]Long postings are being truncated to ~1 kB at this time.

I don't have much experience with Lite, but I'm running 9i Personal Edition. Any information about triggers can be found in the "ALL_TRIGGERS" view. You will want to filter out any rows where OWNER = 'SYS' unless you created your triggers as SYS. As for procedures and functions, you can see what you have created in the "ALL_OBJECTS" view where OBJECT_TYPE = 'PROCEDURE' or 'FUNCTION', once again filtering out rows where OWNER = 'SYS'. To see the code of any procedure or function, select substr(text,1,80) from ALL_SOURCE where NAME = 'function name' ORDER BY LINE.
Hope this helps!
