If an execution plan contains only the Filter keyword, the filter condition does not hit any index. In this case, you need to check the table indexes and configure indexes again to accelerate the SQL query. Note If an execution plan contains One-Time Filter: false, the output is empty...
_version=1. Important If, for any reason, the statement to be analyzed is rejected the variable is not updated. MySQL 9.3 supports a FOR SCHEMA clause, which causes EXPLAIN to behaveas if the statement to be analyzed had been executed in the named database; FOR DATABASE is ...

Note any unusual results, if any should occur. How many bit strings of length 10 either begin with three 0s or end with two 0s? How many bit strings of length 8 have an equal number of 0 and 1? Which of these relations on {0,1,2,3} are partial orderings? (...
Most Boolean functions on N inputs have an exponentially long (as a function of N) minimal description (in any fixed reasonable encoding / formalism). True or False ? A periodic signal has a duty cycle of 25%. If the signal is LOW for 25.5 mic...
because that gateway wasn't accessible from outside. When they went live, they "improved" the password to "Internet1". There are still lots of these passwords around: first letter is a Cap, and the only non-alphabetic char is a 1 at the end. This doesn't add any entropy.141.101.104....
The functions cEE and cBB correspond to an electric permittivity and a magnetic permeability, which deviate from those in the vacuum due to the presence of the cosmological medium. Now, we also have the parity-violating term E · B in the action. Since the coefficient cEB is a function of...
When the cube is scrambled, it might seem to the untrained eye that the cubies can turn any old way. Yet, that's not the case. Because of the way the mechanism works, there are certain principles that limit the cubies' positions. For instance, no matter how you turn the cube, you ...
To determine whether any of the five ARCs is sufficient for 3BP2 recruitment in the context of the full TNKS2 N terminus, we mutated four out of five ARCs, leaving only a single ARC intact (1xxxx, x2xxx, xx3xx, xxx4x, xxxx5). As expected, ARC3 alone (xx3xx) did not bind 3...
