Select the column for which you want to specify a default value. Sandy, if the result is zero records, the answer is create a table that have records, as Bret suggest create a union may be an option or create a table with the dates, make a left join and this will return nulls. SQL> select * from dba_profiles where profile = 'DEFAULT'; If you only query DBA_PROFILES, this does not give sufficient information for the default profile values.

So ; for your conclusion—:“Let’s say I have one column per row. This represents both a space saving and performance improvement. For example, if a sequence number is requested and not used, a statement including a sequence is rolled back, or the databases is turned off and cached sequence values are lost. 8i | Let’s regroup. I generated a single record with default value as 0 and i did a full outer join with the output of the select query, so when no rows returned i get 0 as default value, when value is coming from select query, I choose only the output of the select query. PL/SQL | Blog | If the sequence is dropped after table creation, subsequent inserts will error.

New with database 12c. If you are using a select statement to come up with your default values when you do have rows, how about creating a union in the statement, and have the second query in the union only return 1 row of data, representing your “no rows returned” default value, and have the criteria of that basically indicate that the first query resulted in a rows count of zero. DEFAULT Values Using Sequences. This behaviour can be modified using the ON NULL clause described in the next section. You need to query DBA_PROFILES where profile = ‘DEFAULT’ in order to see the default values. So let's go back to This is a read Normal name resolution rules are used to determine the sequence owner, including expansion of private and public synonyms. How to Assign a Default Value if No Rows Returned from the Select Query. Oracle 12c allows you to modify this behaviour using the ON NULL clause in the default definition.

During table creation, the sequence must exist and you must have select privilege on it for it to be used as a column default. Specifying DEFAULT for the update value sets the value of the column to the default defined for that table. This can be done using a database parameter, "approx_for_count_distinct", which can be set at the session or database-level.
