My question is, since I don't care how many times someone has viewed an object (after the first), I have two options for handling inserts. Do a SELECT count(*) ... and if no records are found, insert a new record. Always exception in oracle just insert a record, and if it throws a DUP_VAL_ON_INDEX exceptions (indicating that there already was such a record), just ignore it. What's the downside of choosing the second option? UPDATE: I guess the best way to put it is : "Is the overhead caused by the exception worse than the overhead caused by the initial select?" sql oracle exception plsql share|improve this question edited Sep 30 '09 at 18:31 OMG Ponies 198k36356415 asked Dec 8 '08 at 20:55 James Curran 71.6k21134217 add a comment| 5 Answers 5 active oldest votes up vote 13 down vote accepted I would normally just insert and trap the DUP_VAL_ON_INDEX exception, as this is the simplest to code. This is more efficient than checking for existence before inserting. I don't consider doing this a "bad smell" (horrible phrase!) because the exception we handle is raised by Oracle - it's not like raising your own exceptions as a flow-control mechanism. Thanks to Igor's comment I have now run two different benchamrks on this: (1) where all insert attempts except the first are duplicates, (2) where all inserts are not duplicates. Reality will lie somewhere between the two cases. Note: tests performed on Oracle 10.2.0.3.0. Case 1: Mostly duplicates It seems that the most efficient approach (by a significant factor) is to check for existence WHILE ins

I explain my problem for sample : I have following procedure: Procedure tomek() begin insert into name_table (id --id is PK ,surname) values (ID ,SURNAME ) select ID, SURNAME from any_table ; exception when DUP_VAL_ON_INDEX then dbms_output.put_line ('value ID=' || || 'value SURNAME=' || ); end tomek; and now my question. In exception I would like get value ID and SURNAME . Is it possible in this sample ?.

In order to do that, create a loop and either log exceptions into a table (you'll have to create it), or show it on the screen. The first approach is a little bit more complicated, but - at the end - you'll benefit from it as you'll have those records stored in a table. The second one is
