Question
So , in my application i have a entity with a virtual column. The column takes values depending on what i save in another column.
On save i have the following error:
java.sql.BatchUpdateException: ORA-54013: INSERT operation disallowed on virtual columns
This is because i am sending a null value on that field.
Does anybody know how to map a virtual column in gorm?
Thanks
La solution
The extended GORM mappings plugins allows you to mark individual columns to be excluded from inserts and updates.
Example:
static mapping = {
readOnlyColumn updateable: false, insertable: false
}
