The https://community.oracle.com/thread/2291573 columns event_system_id1 to event_system_id4 are varchar2(240). In most cases p_po_number will be null as the program is scheduled and the input parameter of p_po_number is not passed. In effect, for most cases, the below query will end like event_system_id1 = NVL(NULL,event_system_id1) I am getting an error of INVALID NUMBER SELECT TO_NUMBER (event_system_id1) FROM c_fnd_intf_transact_q WHERE event_system_id2 = :p_organization_code AND event_system_id4 = DECODE (:p_po_type, :vgc_internal, 'XXX', :vgc_standard ) AND event_system_id1 = NVL (p_po_number, event_system_id1) ---------------------------------------------------------------------------------------------------- I modified the query to SELECT event_system_id1 FROM c_fnd_intf_transact_q WHERE event_system_id2 = :p_organization_code AND event_system_id4 = DECODE (:p_po_type, :vgc_internal, 'XXX', :vgc_standard ) AND event_system_id1 = NVL (p_po_number, event_system_id1) which still threw the same error thus ruling out the cause of the issue being that to_number leaving only the implicit conversions of NVL. --------------------------------------------------------------------------------------------------------- I further modified the query to SELECT TO_NUMBER (event_system_id1) FROM c_fnd_intf_transact_q WHERE event_system_id2
NVL function, replace null in oracle, replace null in SQL The NVL used to replace NULL value with another value. To know more about NULL read post Oracle https://sqlandplsql.com/2012/04/23/oracle-nvl-function/ NULL Syntax:- NVL(expression,replace_value) Note:- expression and replace_value must be compatible data types. Examples :- Consider below table SALARY. Name Type ------- -------- NO NUMBER SAL NUMBER NO SAL 1 2000 2 3000 3 NULL 4 NULL 5 1000 1) Applying NVL to sal column select no,NVL(sal,0) from salary; NO NVL(SAL,0) ------- ----------- 1 2000 2 in oracle 3000 3 0 4 0 5 1000 2) NVL with in-compatible data type not allowed select NVL(sal,'no salary') from salary where no =3; ERROR at line 1: ORA-01722: invalid number Reason : sal column is number and trying to convert to string. It is always a good practice to apply NVL for null columns. Share this:TwitterFacebookGoogleLike this:Like Loading...
