Subject [jira] Commented: (TORQUE-106) Use "boolean" sql type not "bit" sql type with MySQL

Thomas Vandahl commented on TORQUE-106:

I remember a problem with bit columns in the runtime test of Torque against MYSQL-5 which
could be solved by using a new MYSQL JDBC driver, version 5.0 or higher. Could you please
check if that applies to your case, too?

>             Project: Torque

> 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.

> * 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).
>       A very small integer. The signed range is -128 to 127. The unsigned range is 0
to 255.
>       These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero
values are considered true:
