My table is really more like T3 shown below. I am having problems trying grasp and re-code the trigger to accommodate. The real table and pk is quite different. Now, of course in my example, I created the table t1 just as a simple table just to demonstrate my problem. To control and have ability to deal with multiple rows coming in. the key elements are the deferrable constraint to allow the trigger to fireĪnd do it's stuff without raising pk error, as well as the internal buffer in the trigger Trying to understand the "magic" in the solution. I am beginning to think this can scale up to my 100 million rows + I mentioned.
#APEX SQL RECOVERY KEY CODE#
The code that insert uses an anyonymous transaction to pound in hundred of rows at a time.and see any performance woes.(yet) I tested the code you provided, indeed it worked! Your T1 table generated had 10 million rows and it held up well!!! I'd be inclined to tweak the trigger a little to sort out the performance:ħ - an array structure to buffer all the row changesĢ1 l_pk_rows(l_pk_unt+1) := :new.x ģ1 ( select rowid rid, row_number() over ( order by rowid) as r SQL> insert into t1 values (10000,'blah') īut this is not in any way to dismiss your solution - I think its a very nifty mechanism.
Things go a little bit nasty with that at scale:Ģ as select rownum x, rpad(rownum,100,'x') yĤ ( select 1 from dual connect by level alter table t1 add primary key (x ) deferrable initially deferred So, how can I "inject" this "hint" into the query? What approach and can you share any code? To happen dynamically without having to change the code. Insert /*+ ignore_row_on_dupkey_index(t, t_pk) */ into t values ( 1) << THIS DOES NOT give me error, just silently "ignores" it! I want this Insert into t values ( 1) << This would give me the primary key exception I am not sure 100% If I can do what I need to do.Īlter table t add constraint t_pk primary key(x) Stored outlines? The statement that fire doesn't use bind variables, so not sure If I can go this way. Assume I have a table called TĪnother approach I thought of is to use the "hint" of /*+ ignore_row_on_dupkey_index(t, t_pk) */Īgain, I would need to modify the statement! This require that the insert statement is modified to include the following statement. I did some research and found a couple of techniques would could help me, but they both required a change I need a way to "stop Oracle" from raising a exception of "ORA-00001: unique constraint" when bad rows get inserted.Īt first I tried to use a "before insert" trigger, but this got me with messages about mutating table. Periodically, this application inserts rows in a table which causes it to have a Primary key error.
