Grails 1.3.7 Map to sql server 2k8 Date Column - sql-server

Question

We have a legacy grails app running 1.3.7 and having trouble mapping to a mssql server 2k8 table with a date data type.
I've got it mapped with sqlType:'date' it still get the following error when it tries to load the entity ERROR util.JDBCExceptionReporter - Can't convert '2013-07-24' to Timestamp.
Added a custom Dialect extending the SQLServerDialect with the following no difference
registerColumnType( Types.DATE, "date" );

Answer 1

Grails 1.3.7 comes bundles with hibernate 3.3.1 GA. I think there is no SQLServer2008Dialect in this version of Hibernate, only a `SQLServerDialect̀ which is good for 2k and 2k5 versions
You'll have to borrow this class from a later version, as explained in this blog post
I reproduce the class here for archive sakes (from robert-reiz.com)

You'll have to add
dialect = org.hibernate.dialect.SqlServer2008Dialect
in the ̀Datasource.groovy` config file and make this class available to your classpath
WARNING : in the blog post, the base version for Hibernate is 3.6.4 and the code above use a SQLServer2005Dialect class that doesn't exist in the 3.3.1 GA version. I've modified the code above to take this into account (I used SQLServerDialect) while assuming that these class were compatibles. I didn't check this.
