[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3243) VARBINARY primary key with mysql doesn't function

VARBINARY primary key with mysql doesn't function ------------------------------------------------- Key: HHH-3243 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3243 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.1 Environment: MySQL-5.0.51a, hibernate-3.2.1.ga Reporter: Marc Ewert We have a 16-byte UUID type, which should be persisted in a VARBINARY (tinyblob) in a mysql database. But the primary key statement is invalid for mysql: ERROR 11:34:13 [main] (SchemaExport.java:create:274) - Unsuccessful: create table T_GRI_USER (C_ID tinyblob not null, C_ATTRIBUTES text, C_VERSION integer, C_PASSWORD varchar(255), C_VISIBILITIES blob, C_STATE integer not null, C_LOGIN varchar(255) not null unique, C_EMAIL varchar(255), primary key (C_ID)) ERROR 11:34:13 [main] (SchemaExport.java:create:275) - BLOB/TEXT column 'C_ID' used in key specification without a key length The statement should end with ... primary key (C_ID({length})). This has to be done in the class PrimaryKey, which forms this part of the statement without involving the Dialect. The MySQLDialect has also a little bug, it doesn't write the length while defining the tinyblob column. But unfortunately this doesn't solve the SQL-Error. Unfortunately because the dialect is much better patchable for us as the PrimaryKey class deep in hibernate is...
