Like select * from table
Hey man, I would like to ask a question about de-emphasis of sql statements? I
Mean mysql engines have to be aware of which two statements are exactly the same
Despite of variables?? values at runtime. Because in slow log, the execution
counter is
Maintained for each sql statement.

Like select * from table where name’A’ is just
The same as select * from table where name’B’.
The execution plan for both statements is indeed likely (but not guaranteed!)
to be the same. As far as I'm aware, though, MySQL
this?..._///
