Michael Dick updated OPENJPA-1144:
----------------------------------
Remaining Estimate: 0h
Original Estimate: 0h
I don't think table_name would trigger any of the reserved words checking. It's
more likely that we're checking for uniqueness and found the existing column
then (erroneously) creating a new column.
I'd have to look into it a bit more to test this hypothesis. Can you provide
the persistence.xml that you're using (or at least any configuration properties
that you set)?
> Improve support of key generator tables
> ---------------------------------------
>
> Key: OPENJPA-1144
> URL: https://issues.apache.org/jira/browse/OPENJPA-1144
> Project: OpenJPA
> Issue Type: Improvement
> Affects Versions: 1.2.1
> Environment: OS independent, at least on MS SQL Server and MySQL 5
> Reporter: Michael Simons
> Priority: Minor
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> The annotation to tell OpenJPA there's a Table Generator:
> @TableGenerator(name = "pkGenSessionConfig", table = "jdo_keygen",
> pkColumnName =
> "table_name", valueColumnName = "last_used_id", pkColumnValue =
> "session_config", allocationSize
> = 10)
> @Id
> @GeneratedValue(strategy=GenerationType.TABLE,
> generator="pkGenSessionConfig")
> @Column(name="session_config_id", unique=true, nullable=false)
> private int id;
> And here's the according SQL generated by OpenJPA:
> Unknown column 'TABLE_NAME0' in 'where clause' {prepstmnt 32845046 SELECT
> LAST_USED_ID FROM
> jdo_keygen WHERE TABLE_NAME0 = ? FOR UPDATE [params=(String) session_config]}
> [code=1054,
> state=42S22]
> Fay Wang told us that the name "TABLE_NAME0" is created by OpenJPA because
> DBDictionary.getValidColumnName returns "table_name0" where we want
> "table_name".
> Obvisouly "table_name" is _not_ assumed to be a valid column name, but that
> is not quite correct, because at least for the DBMS MySQL 5 and MS SQL Server
> it's legal.
> Furthermore we would appreciate the possibility to influence what's assumed
> a valid name for columns, tables and so on.
