Guillaume Grussenmeyer commented on HHH-3055:
---------------------------------------------

Moreover, the Sun JDBC documentation (http://java.sun.com/javase/6/docs/technotes/guides/jdbc/getstart/mapping.html) states that "The recommended Java mapping for the FLOAT type is as a Java double" and "The recommended Java mapping for the REAL type is as a Java float.".

> 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".
