Mutating Error in Triggers

151 New Member
Can Someone help me how to avoid mutating error while using triggers.

I work on oracle apps. I created a vacation rule such that responsibility is delegated to other person. These details are captured in wf_routing_rule s.

I created a procedure that takes the values from wf_routing_rule s and sends mail using utl_smtp. I created a trigger such that for every row insert in wf_routing_rule s, this procedure is called.

I know that doing a transaction and trigger on same table wil give mutating error.

Is there a way to avoid this ( other than changing the table name).

Glad if there is a different solution for this too.

It didn't work for me either.

Can we try in some other way. My requirement is as soon as end user creates the vacation rule in oracle apps, My procedure has to run. So can we call this procedure in the vacation rules.

Why dont you try using FAST FORMULA?

I will create the procedure and register in Apps as concurrent program. And for each row insert in the table i will call this concurrent program. I hope this will not create any mutating error again

If yes: how to call the concurrent program from trigger.

My friend you are complicating things here.

You can use FND_REQUEST.SUB MIT_REQUEST API to submit a concurrent program programatically .

Try using FAST FORMULA where you can call your procedure as well from there. R12 HRMS provides very good feature of FAST FORMULA

What about the documented method of using 3 triggers to avoid mutating errors.
Before insert for each row to set package variable(array) .
after insert for each row to get the unique id of rows inserted and store sin package array
after insert statement level- to do whatever procesing u want for the rows in packaged array

This doesnt work???

thanks all

it worked for me.

I created a after insert trigger and used pragma autonomous transaction, from there i had to call procedure that has the logic and one more procedure that from here, to send a mail.

for some reason, it worked only if the calling is indirect (calling one procedure from other)

My question is :
1. can we Store all records of column from table on which trigger is written ????
e.g. here in "wf_routing_rul es" this table can i get all role list which is stored in array and pass as an parameter to Procedure !!

Thanx !

Hello, I have a very simple table, and want to create a trigger that updates the date column entry (with the current date), whenever a row gets modified. Is there a simple way of fixing this, or would I have to create 3 extra triggers, a package, etc., as described in most posts about mutating table errors? Could you please explain to me WHY this error happens here (I have not been able to find a clear explanation of what causes them)?

Hello - I'm using Oracle 8i and am running into the infamous mutating table error on an AFTER INSERT OR UPDATE FOR EACH ROW trigger.
