I created a new domain and created the table manually. The table should only contain one record so the only record id will be (1).
The record should be created automatically if not exist but I always get a casting error when trying to retrieve the record. It doesn't matter if I create the record manually first - the get, find or whatever always return in error.
The code that fails:
def int id = 1
def WtStatus wts = WtStatus.get(id)?:new WtStatus(id:1).save(failOnError:true)
The domain:
class WtStatus {
def prodBufferService
int weekUpdated
Date dateUpdated
def beforeInsert() {
dateUpdated = new Date()
weekUpdated = prodBufferService.getCurrentYearWeek()
}
def beforeUpdate() {
dateUpdated = new Date()
}
static constraints = {
dateUpdated nullable:true
weekUpdated nullable:true
}
static mapping = {
table 'wt_status'
version true
id column: "id", type: 'int'
}
}
The create-script for the table:
CREATE TABLE [dbo].[wt_status](
[id] [int] NOT NULL,
[version] [bigint] NOT NULL,
[date_updated] [datetime2](7) NULL,
[week_updated] [int] NULL,
CONSTRAINT [PK__wt_statu__3213E83F77809FC6] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

The problem is the type you are using for your ìd variable, which is int. Since you did not declare the id property in the domain, it will be a Long (Grails default). Note: in the mapping block you only define what will be the relation with the database, that's why the property is still a Long in the domain.
Also, you don't need to use def if you're going to use another type for a variable. Try this:
Long id = 1
WtStatus wts = WtStatus.get(id)?:new WtStatus(id:1).save(failOnError:true)
