Subj:   Re: Different EXPLAIN on identical systems
 
From:   Barry Hull

If the statement is flushing the parser cache for the table, then it probably has a write lock on the table in the first step of the explain for the statement. So, if someone else was creating an index on the table, the statement would not be able to get past the step that takes the write lock until the index build has completed.


Thanks,

Barry
