MySQL Native Driver is in most cases compatible with MySQL Client Library
|
|
|
|
|
(<literal>libmysql</literal>). This section documents incompatibilities
|
|
|
|
|
between these libraries.

<para>
|
|
|
|
|
Values of <literal>bit</literal> data type are returned as binary strings
|
|
|
|
|
(e.g. "\0" or "\x1F") with <literal>libmysql</literal> and as decimal
|
|
|
|
|
strings (e.g. "0" or "31") with <literal>mysqlnd</literal>. If you want the
|
|
|
|
|
code to be compatible with both libraries then always return bit fields as
|
|
|
|
|
numbers from MySQL with a query like this:
|
|
|
|
|
<literal>SELECT bit + 0 FROM table</literal>.
