Description: bad bind variable trigger. Oracle Database Forums on Bytes.

    CREATE OR REPLACE TRIGGER "NEO".TEMP_TR BEFORE INSERT ON TEMP FOR EACH ROW declare c_id number:=0; BEGIN select :new_ID into c_id from dual ; dbms_output.put_line(c_id); End;

basically i want to store :new_ID value into a variable for further processing What is the value of :new_id?

Syntax for old and new keywords in Triggers were :Old.<Column_name> referes the existing value of the column in a record. New.<Column_Name> referes the new value for the column in a record.

And u can directly assign the value to the variable c_id like c_id=:new.id(I am considering ID is the column name)

    SQL> create table temp (id varchar2(15)); Table created. SQL> ed Wrote file afiedt.buf line 9 truncated. 1 CREATE OR REPLACE TRIGGER TEMP_TR BEFORE 2 INSERT ON TEMP FOR EACH ROW 3 DECLARE 4 c_id varchar2(15); 5 BEGIN 6 c_id :=:new.id; 7 dbms_output.put_line('Output from the Trigger c_id. '||c_id); 8* END; 9 / Trigger created. SQL> set serveroutput on; SQL> insert into temp values('Gnk'); Output from the Trigger c_id. Gnk 1 row created. SQL>
