To answer this question, alpha queens must be compared in a larger eco- 374 logical context, not to beta queens within their group, but to queens outside their 375 group—the monogyne fire ant queen. Cooperative-breeding polygyne queens are of 376 lower-fecundity than aggressive monogyne ...
CPU time, elapsed time, logical reads, physical reads, and rows processed are also reported, along with information about recursion level and misses in the library cache. TKPROF can also optionally include the execution plan for each SQL statement in the report, along with counts of how many ...
Logical errors − Where a transaction cannot complete because it has some code error or any internal error condition. System errors − Where the database system itself terminates an active transaction because the DBMS is not able to execute it, or it has to stop because of some system ...
