Documentation
Definition
QQCTF is the number of times a statement was implemented with a temporary result file created by the database optimizer.
If the most expensive execution of a statement was thus implemented, more details about the database sort performed (for example the reason for temporary file creation) are found in the record in table SQ3004_DB4 corresponding to that statement.
Example
The Open SQL statement (with an appropriate internal table declaration for itab) lists all statements (library/SQL package/statement name), files (tables) accessed, and the reason code for temporary file creation which were implemented with a table scan when the most expensive execution occurred:
select b~qqplib b~qqpnam b~qqsnam a~qqtln a~qqtfn a~qqrcod
into corrseponding fields of table itab
from SQ3004_DB4 as a
inner join SQ1000_DB4 as b
where a~qqkey = b~qqkey.
