> In MySQL 5.0.3 the meaning of the BIT data type changed.  It used to be equivalent to
tinyint(1) but now it is a new bitwise datatype.  This means that when Torque generates SQL
files with a "bit" data type (mapped to the Java boolean) it is incorrect.
> I suggest that Torque map the Torque "bit" type to the MySQL "Boolean" type instead when
generating SQL.  See the reference from the MySQL manual below.
> http://dev.mysql.com/doc/refman/5.0/en/numeric-type-overview.html
> * BIT[(M)]
>       A bit-field type. M indicates the number of bits per value, from 1 to 64. The default
is 1 if M is omitted.
>       This data type was added in MySQL 5.0.3 for MyISAM, and extended in 5.0.5 to MEMORY,
InnoDB, and BDB. Before 5.0.3, BIT is a synonym for TINYINT(1).
>     
> *  TINYINT[(M)] [UNSIGNED] [ZEROFILL]
>       A very small integer. The signed range is -128 to 127. The unsigned range is 0
to 255.
>    
> * BOOL, BOOLEAN
>       These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero
values are considered true:
