returns 8.

Based on the code originated  by Hartmut Holzgraefe <hartmut@six.de>.

@item

Added logical XOR.

The one that with a query like:

select 1 XOR 1;

returns 0;

Based on the code originated by Hartmut Holzgraefe <hartmut@six.de>.

@item

Add function CHEDK_LOCK("lock_name"). 

This function checks if the lock of the certain name is available or not. 

This function does not attempt to take a look.

It is used like this:

   SELECT CHECK_LOCK("some_lock");

it will return 1 if the lock is held by a process (including by

itself), 0 if it is currently not held by anyone and NULL on

errors.

Based on the code originated  by Hartmut Holzgraefe <hartmut@six.de>.

@item

Removed @code{mysql_ssl_clear()}, as this was not needed.

@item

@code{DECIMAL} and @code{NUMERIC} types can now read exponential numbers.
