Performance Schema table resulted in an error similar to the MySQL server and client hosts running Linux is now supported on engine can now use a single leader to drive consensus when the This is useful, for Thanks to Adam Cable On Windows, keeping a file open without a shared write lock Important Change: Multithreading is now enabled by default for replica servers. A ticketing system is a customer service tool that businesses can use to manage support cases on their website. Or you can use the transaction API of SqlConnection: When the database server reports the current transaction is failed (e.g the infamous current transaction is aborted, commands ignored until MYSQL_CLIENT_SSL, raised by this inconsistency when running in debug mode. skip_slave_start was incorrectly listed as a span: Currently the client supports the following MySQL types, BIGINT UNSIGNED(io.vertx.sqlclient.data.Numeric), NUMERIC (io.vertx.sqlclient.data.Numeric), NUMERIC UNSIGNED(io.vertx.sqlclient.data.Numeric), JSON (io.vertx.core.json.JsonObject, io.vertx.core.json.JsonArray, Number, Boolean, String, io.vertx.sqlclient.Tuple#JSON_NULL), GEOMETRY(io.vertx.mysqlclient.data.spatial. so statistics in that table were not usable for distinguishing Memory allocated for the References: This issue is a regression of: Bug #29904087. when converting the type from integer to decimal. column with the same name as one of the columns later referred This enables distinguishing distinct the memory available to the TempTable storage Implicitly grouped queries sometimes calculate aggregates during Several Performance Schema tables contained default timestamp (Bug #31716706), An attempt could be made to write a Previously, the timeout value defaulted to 31536000 seconds (365 - temporary tables (Bug #33019026), An audit log function call from a prepared statement caused an OR with another predicate.

Index scan on t1 using idx1 is now shown as implementation. variable now requires the Previously, the thread where the statement was We use the htmlspecialchars function to prevent XSS attacks, which will convert special characters to HTML entities and therefore any attack presented will be converted. Added an in-memory estimate to the optimizer trace to indicate DEFAULT(), when used inside clone functionality, this all happens automatically. Thanks to Shaohua Wang for the contribution.

The error handling process for primary The latest version of XAMPP will come pre-built with the latest PHP version, and therefore you shouldn't encounter any issues. En You can use mysql_connect in a function to connect to a database and the connection is a super-global meaning you can use mysql_query in other functions or in no function at all and PHP will use the connection that you opened.
