Description: ------------ In MDB2_Driver_Reverse_mysql::getTableFieldDefinition(), the length property is only set when the returned length value from MDB2_Driver_Datatype_Common::mapNativeDatatype() is > 0. However, it is the responsibility of MDB2_Driver_Datatype_Common::mapNativeDatatype() to ensure that it returns the correct length value, or null. As a result, I would propose that the MDB2_Driver_Reverse_mysql::getTableFieldDefinition() method only check to see if $length is not null, and if so, set the property. This also allows custom data types in MDB2 to sneakily store "alternative" data in the length property - for example, the set of allowed values for an "enum" native type can be returned as the length.

is the length property the place for such things?

Apart from the "abuse" of the length property for other purposes, I agree with your remarks. Fixed in CVS.
