[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3055) Incorrect type of SQLServer column for Java 'float' field

Anthony Ogier commented on HHH-3055:
------------------------------------

Actually it doesn't seem to be enough ... finally I did like you, creating my own dialect, extending org.hibernate.dialect.SQLServerDialect and including that code into the constructor :

	registerColumnType( Types.FLOAT, "real" );

But then, every Entity using java Float fields must map to a "real" type field in the database. Moreover, if the database contains "float" fields, then one must add a mapping to another java type ...

I'm not sure it's the good solution to handle SQL Server "real" type into hibernate...

> When mapping a Java field of type 'float' to a SQLServer table, the corresponding database column is created with type 'float', which is not correct as SQL Server floats are double precision, while Java floats are simple precision.
> The corresponding column should be created with type "real".
