I have multiple threads trying to update a MySQL database? is executeUpdate method thread-safe to use?
No, it is not thread-safe to use.
In fact, if some other thread uses a statement, and then another thread calls executeUpdate(), then the other thread’s
ResultSets, if any, will be closed. JavaDoc for java.sql.Statement (of which PreparedStatement is a subtype) “All execution methods in the Statement interface implicitly close a statment’s current ResultSet object if an open one exists.”Furthermore, it’s unlikely that a given implementation of
executeUpdate()would be written to be mulit-thread safe.You should either syncrhonize all use of the statement and resulting result sets, or make multiple connections so that each thread uses its own JDBC
Connectionto the database.. I would recommend the latter.
